The Efficacy and Safety of Drug-Coated Balloons in the Treatment of Acute Myocardial Infarction

The incidence of acute myocardial infarction (AMI) is increasing year by year, which seriously endangers human health around the world. The preferred treatment strategy for AMI patients is the use of drug-eluting stents (DES), as there is ample evidence to suggest that stent implantation can reduce major adverse cardiovascular events (MACEs). With the application of drug-coated balloons (DCBs) and the enhancement of the concept of interventional without implantation, the question is whether DCBs can be safely and effectively used in patients with AMI? The purpose of this study was to investigate the safety and effectiveness of DCBs in the treatment of AMI. A retrospective review of clinical data was conducted on 55 AMI patients who underwent primary percutaneous coronary intervention (PCI) from January 2020 to December 2021. Of these patients, 25 were treated with DCBs and 30 were treated with DESs. Optical coherence tomography (OCT) was used to measure the minimum lumen diameter, lumen stenosis, and coronary artery dissection before and after surgery, and angina pectoris attacks and various MACEs were recorded at 1, 6, and 12 months after surgery. The results showed that there were no significant differences in clinical baseline data between the two groups. However, the minimum lumen diameter of the DCB group immediately after the operation was smaller than that of the DES group, and the stenosis degree of the lumen in the DCB group was higher than that in the DES group. The incidence of coronary artery dissection in the DCB group was significantly higher than that in the DES group, but the majority of them were type B. At 1, 6, and 12 months after treatment, there was no significant difference in the occurrence of MACEs between the two groups. In conclusion, DCBs is a safe and effective treatment for AMI. However, the incidence of coronary artery dissection in DCB patients is higher than that in DES patients, but the majority of them are type B. .

Drug-coated balloons for treating de novo lesions in large coronary vessels:A case report

BACKGROUND Percutaneous transluminal coronary angioplasty,while an effective intervention,can frequently lead to acute occlusion with severe consequences.Although clinical trials have demonstrated the efficacy of drug-coated balloons(DCB)in treating acute coronary artery occlusion and in preventing restenosis,there has been limited exploration on the use of DCB in treating de novo lesions in large vessels.Currently,DCB are only recommended for patients with small vessel lesions and in-stent restenosis lesions,those at high risk of bleeding,and other special groups of patients.CASE SUMMARY This report presents a case of successful drug-coated balloon treatment of de novo lesions in large coronary vessels.Postoperatively,the patient demonstrated favorable recovery,with subsequent examination results revealing no significant differences from the previous examination.CONCLUSION The successful treatment of the patient in our case highlights the potential of DCB in the treatment of de novo lesions in large coronary vessels.

Drug-coated balloons for the treatment of ostial left anterior descending or ostial left circumflex artery lesions:a patientlevel propensity score-matched analysis

BACKGROUND Controversy exists as to the optimal treatment approach for ostial left anterior descending(LAD)or ostial left circumflex artery(LCx)lesions.Drug-coated balloons(DCB)may overcome some of the limitations of drug-eluting stents(DES).Therefore,we investigated the security and feasibility of the DCB policy in patients with ostial LAD or ostial LCx lesions,and compared it with the conventional DES-only strategy.METHODS We retrospectively enrolled patients with de novo ostial lesions in the LAD or LCx who underwent interventional treatment.They were categorized into two groups based on their treatment approach:the DCB group and the DES group.The treatment strategies in the DCB group involved the use of either DCB-only or hybrid strategies,whereas the DES group utilized crossover or precise stenting techniques.Two-year target lesion revascularization was the primary endpoint,while the rates of major adverse cardiovascular events,cardiac death,target vessel myocardial infarction,and vessel thrombosis were the secondary endpoints.Using propensity score matching,we assembled a cohort with comparable baseline characteristics.To ensure result analysis reliability,we conducted sensitivity analyses,including interaction,and stratified analyses.RESULTS Among the 397 eligible patients,6.25%of patients who were planned to undergo DCB underwent DES.A total of 108 patients in each group had comparable propensity scores and were included in the analysis.Two-year target lesion revascularization occurred in 5 patients(4.90%)and 16 patients(16.33%)in the DCB group and the DES group,respectively(odds ratio=0.264,95%CI:0.093–0.752,P=0.008).Compared with the DES group,the DCB group demonstrated a lower major adverse cardiovascular events rate(7.84%vs.19.39%,P=0.017).However,differences with regard to cardiac death,non-periprocedural target vessel myocardial infarction,and definite or probable vessel thrombosis between the groups were non-significant.CONCLUSIONS The utilization of the DCB approach signifies an innovative and discretionary strategy for managing isolated ostial lesions in the LAD or LCx.Nevertheless,a future randomized trial investigating the feasibility and safety of DCB compared to the DES-only strategy specifically for de novo ostial lesions in the LAD or LCx is highly warranted.

Drug-coated balloon angioplasty for the treatment of intracranial arterial stenosis in a young stroke patient:A case report

BACKGROUND Intracranial arterial narrowing is a significant factor leading to brief episodes of reduced blood flow to the brain,known as transient ischemic attacks,or fullblown strokes.While atherosclerosis is commonly associated with intracranial arterial narrowing,it is frequently of a non-atherosclerotic nature in younger patients.CASE SUMMARY Here,we present the case of a young stroke patient with narrowing of the middle cerebral artery(MCA),characterized as non-atherosclerotic lesions,who experienced an ischemic stroke despite receiving standard drug therapy.The patient underwent digital subtraction angiography(DSA)to assess the entire network of blood vessels in the brain,revealing significant narrowing(approximately 80%)in the M1 segment of the right MCA.Subsequently,the patient underwent Drug-Coated Balloon Angioplasty to treat the stenosis in the right MCA's M1 segment.Follow-up DSA confirmed the resolution of stenosis in this segment.Although the remaining branches showed satisfactory blood flow,the vessel wall exhibited irregularities.A review of DSA conducted six months later showed no evident stenosis in the right MCA,with a smooth vessel wall.CONCLUSION The use of drug-coated balloon angioplasty demonstrated favorable outcomes in repairing and reshaping the blood vessel wall in young patients.Therefore,it may be considered a promising treatment option for similar cases.

Study of Secondary Cosmic Rays and Astronomical X-Ray Sources using Small Stratospheric Balloons

The X-ray sources of the universe are extraterrestrial in nature which emit X-ray photons.The closest strong X-ray source is the Sun,which is followed by various compact sources such as neutron stars,black holes,the Crab pulsar,etc.In this paper,we analyze the data received from several low-cost lightweight meteorological balloon-borne missions launched by the Indian Centre for Space Physics.Our main interest is to study the variation of the vertical intensity of secondary cosmic rays,the detection of strong X-ray sources,and their spectra in the energy band of^(1)0–80 keV during the complete flights.Due to the lack of an onboard pointing system,low exposure time,achieving a maximum altitude of only~42 km,and freely rotating the payload about its axis,we modeled the background radiation flux for the X-ray detector using physical assumptions.We also present the source detection method,observation of the pulsation of the Crab(^(3)3 Hz),and spectra of some sources such as the quiet Sun and the Crab pulsar.

A novel cerebrovascular drug-coated balloon catheter for treating symptomatic intracranial atherosclerotic stenosis lesions:Study protocol for a prospective,multicenter,single-arm,target-value clinical trial

Background:Previous single-center studies have demonstrated that drug-coated balloons(DCBs)may reduce restenosis rates,which is an important factor affecting the prognosis for intracranial interventional therapy.However,currently available cardiac DCBs are not always suitable for the treatment of intracranial atherosclerotic stenosis(ICAS).This study aimed to evaluate the safety and efficacy of a novel DCB catheter designed for patients with severely symptomatic ICAS.Methods:This prospective,multicenter,single-arm,target-value clinical trial was conducted in 9 Chinese stroke centers to evaluate the safety and efficacy of a novel DCB catheter for treating symptomatic severe ICAS.Primary metrics and other indicators were collected and analyzed using SAS version 9.4(SAS Institute,Cary,NC,USA).Results:A total of 155 patients were enrolled in this study.The preliminary collection of follow-up data has been completed,while data quality control is ongoing.Conclusion:Results of this study demonstrated the patency rate,safety,and effectiveness of a novel on-label paclitaxel DCB designed for the treatment of ICAS.Ethics and dissemination:This study,involving human participants,was reviewed and approved by the Ethics Committee of Drugs(Devices)Clinical Experiment at Henan Provincial People’s Hospital(reference number:2020-145-03)and other research centers participating in the clinical trial.The results of this study will be presented at international conferences and sent to peer-reviewed journals for publication.Standard protocol items:The Recommendations for Interventional Trials checklist was used when drafting the study protocol.Trial registration number:Registered with the Chinese Clinical Trial Registry on June 11,2021(Chi CTR2100047223).

Drug-coated balloons are not inferior to drug-coated stents in the treatment of acute myocardial infarction and shorten the duration of dual antiplatelet treatment

Background:Drug-coated balloons(DCBs)are an up-and-coming tactic in treating in-stent restenosis and coronary artery small vessel disease,but their efficacy in treating acute myocardial infarction needs to be further explored.Methods:A meta-analysis of 7 studies was conducted to make a comparison with the results of DCB and drug-eluting stent implantation after a median follow-up of 15 months.Results:A total of 922 patients were included in this analysis in total,including 375 patients in the DCB group and 547 patients in the stent group.A total of 962 vascular diseases were manifested in the 2 groups.After 6 to 24 months of follow-up,there was no statistically significant difference with respect to major adverse cardiovascular events(odds ratio[OR]:0.82;95%confidence interval[CI]:0.52–1.29;Z=0.85;P=0.39),cardiac death(OR:0.92;95%CI:0.39–2.12;Z=0.21;P=0.84),target lesion revascularization(OR:1.09;95%CI:0.53–2.25;Z=0.24;P=0.81),late lumen loss(MD:−0.05;95%CI:−0.15 to 0.06;Z=0.85;P=0.40),or dual antiplatelet therapy(DAPT)(OR:1.04;95%CI:0.53–2.05;Z=0.11;P=0.91)between the 2 groups.In the DCB group,persistent residual stenosis or C-F dissection occurrence necessitated that a total of 30 patients receive extra bailout implantations.The rate of bailout stenting was 11.8%(95%CI:7.1–16).Moreover,the DCB group had a shorter DAPT duration compared with the stent group.Conclusion:Drug-coated balloons with shorter DAPT durations may be as effective and safe as stent therapy in treating acute myocardial infarction.

Restenosis of a drug eluting stent on the previous bioresorbable vascular scaffold successfully treated with a drug-coated balloon: A case report

BACKGROUND The in-stent restenosis(ISR)rates are reportedly inconsistent despite the increased use of second-generation drug eluting stent(DES).Although bioresorbable vascular scaffold(BVS)have substantial advantages with respect to vascular restoration,the rate of scaffold thrombosis is higher with BVS than with DES.Optimal treatment strategies have not been established for DES-ISR to date.CASE SUMMARY We report on a case of a 60-year-old man patient with acute coronary syndrome.He had a history of ST-segment elevation myocardial infarction associated with very late scaffold thrombosis and treated with a DES.Coronary angiography revealed significant stenosis,suggesting DES-ISR on the previous BVS.Optical coherence tomography(OCT)identified a plaque rupture and a disrupted scaffold strut in the neointimal proliferation of DES.To treat the DES-ISR on the previous BVS,we opted for a drug-coated balloon(DCB)after a balloon angioplasty using a semi-compliant and non-compliant balloon.The patient did not experience adverse cardiovascular events on using a DCB following the use of intensive dual antiplatelet therapy and statin for 24 mo.CONCLUSION This case highlights the importance of OCT as an imaging modality for characterizing the mechanism of target lesion failure.The use of a DCB following the administration of optimal pharmacologic therapy may be an optimal strategy for the treatment and prevention of recurrent BVS thrombosis and DES-ISR.

Preliminary experience with drug-coated balloon angioplasty in primary percutaneous coronary intervention

We evaluated the clinical feasibility of using drugcoated balloon(DCB) angioplasty in patients undergoingprimary percutaneous coronary intervention(PPCI). Between January 2010 to September 2014,89 STelevation myocardial infarction patients(83% male,mean age 59 ± 14 years) with a total of 89 coronary lesions were treated with DCB during PPCI. Clinical outcomes are reported at 30 d follow-up. Left anterior descending artery was the most common target vessel for PCI(37%). Twenty-eight percent of the patients had underlying diabetes mellitus. Mean left ventricular ejection fraction was 44% ± 11%. DCB-only PCI was the predominant approach(96%) with the remaining 4% of patients receiving bail-out stenting. Thrombolysis in Myocardial Infarction(TIMI) 3 flow was successfully restored in 98% of patients. An average of 1.2 ± 0.5 DCB were used per patient,with mean DCB diameter of 2.6 ± 0.5 mm and average length of 23.2 ± 10.2 mm. At 30-d follow-up,there were 4 deaths(4.5%). No patients experienced abrupt closure of the infarctrelated artery and there was no reported target-lesion failure. Our preliminary experience showed that DCB angioplasty in PPCI was feasible and associated with a high rate of TIMI 3 flow and low 30-d ischaemic event.

Avoiding revascularization strategy versus revascularization with drug-coated balloon for the treatment of superficial femoral artery occlusive disease

Objective:The aim of this study was to compare the efficacy,safety and treatment costs of superficial femoral artery revascularization(SFA)with drug-coated balloon(DCB)versus avoiding revascularization strategy for the treatment of symptomatic SFA disease.Methods:This retrospective single-center study reviewed 96 patients(113 limbs)with severe stenosis and occlusive SFA disease.All patients underwent either DCB(Group 1:n=55 limbs)or nonrevascularization(Group2:n=58 limbs)between March 2015 and June 2019.The improvement of Rutherford class,walking impairment questionnaire score(WIQ),target limb reintervention,perioperative major adverse events,the catheterization laboratory cost and length of hospital stay were compared.The limb salvage and survival rates were calculated using the Kaplan-Meier method.Univariate and multivariate logistic regression analysis were performed to assess the association between factors and the improvement of Rutherford category at 12 months.Results:The median follow-up time of Groups 1 and 2 was 17 and 33 months,respectively.At 12 months,the Rutherford category significantly decreased in both groups(P<0.001),with no significant difference(79.7%vs.64.3%,P=0.074).Furthermore,multivariate analysis showed that the selected therapeutic method was not an influential factor for the improvement of Rutherford class at 12 months.The WIQ overall score as well as three subscales scores(distance,speed and stair-climbing),the survival rate,limb salvage rate and the length of stay between the two groups were comparable.The perioperative adverse events rate and catheterization laboratory cost in Group 2 was significantly lower compared to Group 1[(34253.69±28172.87)yuan vs.(56936.76±41278.36)yuan,P=0.001].Conclusions:This study suggests that avoiding superficial femoral artery revascularization strategy has favorable efficacy and safety outcomes compared to combining revascularization with DCB in selected patients.

A Case Summary of the Application of a Drug-eluting Stent Combined with a Drug-Coated Balloon in Left Main Coronary Artery Disease

Objective:To evaluate the clinical efficacy of a drug-eluting stent(DES)combined with a drug-coated balloon(DCB)in the treatment of left main coronary artery bifurcation lesions.Methods:A retrospective analysis was conducted on the clinical data of eight patients with left main coronary artery bifurcation lesions treated with a DES combined with a DCB who were admitted to our hospital from July 2016 to July 2017.These eight patients all underwent DES treatment for their left main coronary artery and left anterior descending coronary artery lesions,and DCB treatment at the ostium of the left circumflex artery;six of the patients underwent surgical procedures under the guidance of intravascular ultrasonography.Immediate postoperative angiography was used to evaluate the patency of the diseased vessels,and the restenosis rate at the 6-month follow-up after the operation and the incidence of serious clinical events within 6 months were assessed as well.Results:The use of a DES combined with a DCB in the treatment of left main coronary artery bifurcation lesions had a low restenosis rate(left main coronary artery(8.4±5.3)%,left anterior descending coronary artery(18.2±5.0)%,left circumflex artery(30.5±16.5)%).No serious clinical events occurred in any patients.Conclusion:A DES combined with a DCB is a safe and effective interventional treatment for left main artery coro-nary bifurcation lesions.

Chinese expert consensus on the clinical application of drugcoated balloon(2^(nd) Edition)

Percutaneous coronary interventions have progressed through the era of plain balloon dilation, bare-metal stent insertion to drug-eluting stent treatment, which has significantly reduced the acute occlusion and restenosis rates of target vessels and improved patient prognosis, making drug-eluting stents the mainstream interventional treatment for coronary artery disease. In recent years, drug-coated balloons(DCBs) have become a new treatment strategy for coronary artery disease, and the drugs used in the coating and the coating technology have progressed in the past years. Without permanent implant, a DCB delivers antiproliferative drugs rapidly and uniformly into the vessel wall via the excipient during a single balloon dilation. Many evidence suggests that DCB angioplasty is an effective measure for dealing with in-stent restenosis and de novo lesions in small coronary vessels.As more clinical studies are published, new evidence is emerging for the use of DCB angioplasty in a wide range of coronary diseases, and the indications are expanding internationally. Based on the latest research from China and elsewhere, the Expert Writing Committee of the Chinese Expert Consensus on Clinical Applications of Drug-Coated Balloon has updated the previous DCB consensus after evidence-based discussions and meetings in terms of adequate preparation of in-stent restenosis lesions, expansion of the indications for coronary de novo lesions, and precise guidance of DCB treatment by intravascular imaging and functional evaluation.

Significance of balloon aortic valvuloplasty as palliative procedure for symptom benefit in patients with severe aortic stenosis

Aortic stenosis(AS)stands out as the most prevalent individual valvular defect globally.The onset and progression of AS mirror an active process akin to atherosclerosis,and the traditional triad of symptoms includes chest pain,breathlessness,and loss of consciousness.Prognosis takes a significant downturn when symptoms manifest,with mortality reaching approximately 50%-85% within the subsequent 5 years after symptom onset.

Effi cacy of partial and complete resuscitative endovascular balloon occlusion of the aorta in the hemorrhagic shock model of liver injury

BACKGROUND:Resuscitative endovascular balloon occlusion of the aorta(REBOA)can temporarily control traumatic bleeding.However,its prolonged use potentially leads to ischemia-reperfusion injury(IRI).Partial REBOA(pREBOA)can alleviate ischemic burden;however,its security and eff ectiveness prior to operative hemorrhage control remains unknown.Hence,we aimed to estimate the effi cacy of pREBOA in a swine model of liver injury using an experimental sliding-chamber ballistic gun.METHODS:Twenty Landrace pigs were randomized into control(no aortic occlusion)(n=5),intervention with complete REBOA(cREBOA)(n=5),continuous pREBOA(C-pREBOA)(n=5),and sequential pREBOA(S-pREBOA)(n=5)groups.In the cREBOA and C-pREBOA groups,the balloon was inflated for 60 min.The hemodynamic and laboratory values were compared at various observation time points.Tissue samples immediately after animal euthanasia from the myocardium,liver,kidneys,and duodenum were collected for histological assessment using hematoxylin and eosin staining.RESULTS:Compared with the control group,the survival rate of the REBOA groups was prominently improved(all P<0.05).The total volume of blood loss was markedly lower in the cREBOA group(493.14±127.31 mL)compared with other groups(P<0.01).The pH was significantly lower at 180 min in the cREBOA and S-pREBOA groups(P<0.05).At 120 min,the S-pREBOA group showed higher alanine aminotransferase(P<0.05)but lower blood urea nitrogen compared with the cREBOA group(P<0.05).CONCLUSION:In this trauma model with liver injury,a 60-minute pREBOA resulted in improved survival rate and was effective in maintaining reliable aortic pressure,despite persistent hemorrhage.Extended tolerance time for aortic occlusion in Zone I for non-compressible torso hemorrhage was feasible with both continuous partial and sequential partial measures,and the significant improvement in the severity of acidosis and distal organ injury was observed in the sequential pREBOA.

Effect of endoscopic sphincterotomy and endoscopic papillary balloon dilation endoscopic retrograde cholangiopancreatographies on the sphincter of Oddi

BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP),with its clinical ad-vantages of less trauma and faster recovery,has become the primary treatment for choledocholithiasis.AIM To investigate the effects of different ERCP procedures on the sphincter of Oddi.METHODS The clinical data of 91 patients who underwent ERCP at Yixing Hospital of Traditional Chinese Medicine between February 2018 and February 2021 were analyzed retrospectively.The patients were divided into endoscopic sphinc-terotomy(EST,n=24)and endoscopic papillary balloon dilation(EPBD,n=67)groups.The duration of operation,pancreatic development,pancreatic sphinc-terotomy,intubation difficulties,stone recurrence,and incidence of reflux cho-langitis and cholecystitis were statistically analyzed in patients with a history of choledocholithiasis,pancreatitis,and Oddi sphincter dysfunction in the EST and EPBD groups.RESULTS Differences in hypertension,diabetes,increased bilirubin,small diameter of the common bile duct,or ampullary diverticulum between the two groups were not significant.Statistically significant differences were observed between the two groups concerning sex and age(<60 years).Patients with a history of choledocholithiasis,pancreatitis,and Oddi sphincter dysfunction were higher in the EST group than in the EPBD group.The number of cases of pancreatic development,pancreatic duct sphincterotomy,and difficult intubation were higher in the EST group than in the EPBD group.The number of Oddi’s sphincter manometries,ERCP surgical outcomes,and guidewires entering the pancreatic duct several times in EST group were lower than those in the EPBD group.The numbers of stone recurrences,reflux cholangitis,and cholecystitis were higher in the EST group than in the EPBD group.CONCLUSION In summary,common bile duct stones,pancreatitis history,and multiple guided wire introductions into the pancreatic duct are independent risk factors for EST and EPBD.Based on this evidence,this study can provide actionable insights for clinicians and researchers.

Balloon dilation of congenital perforated duodenal web in newborns: Evaluation of short and long-term results

BACKGROUND Incomplete congenital duodenal obstruction(ICDO)is caused by a congenitally perforated duodenal web(CPDW).Currently,only six cases of balloon dilatation of the PDW in newborns have been described.AIM To present our experience of balloon dilatation of a perforated duodenal memb-rane in newborns with ICDO.METHODS Five newborns who underwent balloon dilatation of the CPDW along a prein-stalled guidewire between 2021 and 2023 were included.Nineteen newborns diagnosed with ICDO who underwent laparotomy were included in the control group.RESULTS In all cases,good anatomical and clinical results were obtained.In three cases,a follow-up study was conducted after 1 year.The average time to start enteral feeding per os was significantly earlier in the study group(4.4 d)than in the laparotomic group(21.2 days;P<0.0001).The time spent by patients in the intensive care unit and hospital after balloon dilatation was also significantly shorter.We determined the selection criteria for possible and effective CPDW balloon dilatation in newborns as follows:(1)Presence of dynamic radiographic signs of the passage of a radiopaque substance beyond the zone of narrowing or radiographic signs of pneumatisation of the duodenum and small bowel distal to the web;(2)presence of endoscopic signs of CPDW;(3)successful cannulation with a guidewire performed parallel to the endoscope,with holes in the congenital duodenal web;and(4)successful positioning of the balloon performed along a freestanding guidewire on the web.CONCLUSION Strictly following selection criteria for newborns with ICDO caused by CPDW ensures that endoscopic balloon dilatation using a pre-installed guidewire is safe and effective and shows good 1-year follow-up results.

Clinical efficacy of laparoscopic cholecystectomy combined with endoscopic papillary balloon dilation in treatment of gallbladder stones with common bile duct stones: A retrospective study

BACKGROUND The incidence of cholelithiasis has been on the rise in recent years,but the choice of procedure is controversial.AIM To investigate the efficacy of laparoscopic cholecystectomy(LC)combined with endoscopic papillary balloon dilation(EPBD)in patients with gallbladder stones(GS)with common bile duct stones(CBDS).METHODS The clinical data of 102 patients with GS combined with CBDS were selected for retrospective analysis and divided into either an LC+EPBD group(n=50)or an LC+endoscopic sphincterotomy(EST)group(n=52)according to surgical methods.Surgery-related indexes,postoperative recovery,postoperative complications,and expression levels of inflammatory response indexes were compared between the two groups.RESULTS Total surgical time,stone free rate,rate of conversion to laparotomy,and successful stone extraction rate did not differ significantly between the LC+EPBD group and LC+EST group.Intraoperative hemorrhage,time to ambulation,and length of hospitalization in the LC+EPBD group were lower than those of the LC+EST group(P<0.05).The rate of total complications of the two groups was 9.80%and 17.65%,respectively,and the difference was not statistically significant.No serious complications occurred in either group.At 48 h postoperatively,the expression levels of interleukin-6,tumor necrosis factor-α,high-sensitivity Creactive protein,and procalcitonin were lower in the LC+EPBD group than in the LC+EST group(P<0.05).At 3 d postoperatively,the expression levels of aspartate transaminase,alanine transaminase,and total bilirubin were lower in the LC+EPBD group than in the LC+EST group(P<0.05).CONCLUSION LC combined with EPBD and LC combined with EST are both effective procedures for the treatment of GS with CBDS,in which LC combined with EPBD is beneficial to shorten the patient’s hospitalization time,reduce the magnitude of elevated inflammatory response indexes,and promote postoperative recovery.

Application of Clinical Care Pathway in Perioperative Patients with Autologous Arteriovenous Fistula Balloon Expansion

[Objective] To explore the effect of clinical care pathways in perioperative patients with autologous arteriovenous fistula balloon expansion. [Method] 202 patients undergoing autologous arteriovenous fistula from July 2021 to June 2022 were randomly divided into a control group (101 cases) and an observation group (101 cases) to compare the incidence rates of postoperative complications, hospitalization days, hospitalization expenses, knowledge of self-management of arteriovenous fistula and nursing satisfaction. [Results] In the observation group, the incidence of arteriovenous fistula was higher than that of the control group, and the hospitalization days and hospitalization costs were lower than that of the control group. The difference between the two groups was statistically significant (P < 0.05). [Conclusion] The application of the clinical nursing path to intervene in patients with autologous arteriovenous fistula balloon dilation can reduce the incidence of postoperative complications, shorten the hospital length of time, reduce hospitalization costs and improve patient satisfaction, which is clinical promotion significance.

Pseudoaneurysm formation following transarterial embolization of traumatic carotid-cavernous fistula with detachable balloon:An institutional cohort long-term study

BACKGROUND The goal of therapy for traumatic carotid-cavernous fistula(TCCF)is the elimination of fistula while maintaining patency of the parent artery.The treatment for TCCF has evolved from surgery to endovascular management using detachable balloons,coils,liquid embolic agents,covered stents,or flow-diverter stent through arterial or venous approaches.Despite the withdrawal of detachable balloons from the market in the United States since 2004,transarterial embolization with detachable balloons has currently remained the best initial treatment for TCCF in several countries.However,the pseudoaneurysm formation following transarterial detachable balloon embolization has rarely been observed in long-term follow-up.AIM To determine the occurrence and long-term follow-up of pseudoaneurysm after transarterial detachable balloon for TCCF.METHODS Between January 2009 and December 2019,79 patients diagnosed with TCCF were treated using detachable latex balloons(GOLDBAL)of four sizes.Pseudoaneurysm sizes were stratified into five grades for analysis.Initial and follow-up assessments involved computed tomography angiography at 1 month,6 month,1 year,and longer intervals for significant cases.Clinical follow-ups occurred semi-annually for 2 years,then annually.Factors analyzed included sex,age,fistula size and location,and balloon size.RESULTS In our cohort of 79 patients treated for TCCF,pseudoaneurysms formed in 67.1%,with classifications ranging from grade 0 to grade 3;no grade 4 or giant pseudoaneurysms were observed.The majority of pseudoaneurysms did not progress in size,and some regressed spontaneously.Calcifications developed in most large pseudoaneurysms over 5-10 years.Parent artery occlusion occurred in 7.6%and recurrent fistulas in 16.5%.The primary risk factors for pseudoaneurysm formation were identified as the use of specific balloon sizes,with balloon SP and No.6 significantly associated with its occurrence(P=0.005 and P=0.002,respectively),whereas sex,age,fistula size,location,and the number of balloons used were not significant predictors.CONCLUSION Pseudoaneurysm formation following detachable balloon embolization for TCCF is common,primarily influenced by the size of the balloon used.Despite this,all patients with pseudoaneurysms remained asymptomatic during long-term follow-up.
