Interventional treatment of acute hepatic artery occlusion after liver transplantation

BACKGROUND: With the development of the associated technology, interventional treatment has become an important method for the treatment of hepatic artery occlusion in some countries. This study was undertaken to evaluate the role of interventional methods in the diagnosis and treatment of acute hepatic artery occlusion after liver transplantation. METHODS: The diagnosis and treatment of 9 cases of acute hepatic artery occlusion after liver transplantation were retrospectively analyzed. RESULTS: In 109 cases of liver transplantation, 9 were diagnosed by angiography. Among them, 7 were diagnosed by Doppler ultrasound. After transcatheter thrombolysis, the hepatic arteries were partially or totally patent again in 6 cases of hepatic artery occlusion after liver transplantation, and stent placements in the hepatic artery were performed in 5 cases. All stents proved patent and no patient required another liver transplantation. CONCLUSIONS: Angiography plays an important role in diagnosing hepatic artery complications after liver transplantation. Interventional therapy is a valuable method in the treatment of acute hepatic artery occlusion after liver transplantation.

Mimicking aneurysm in a patient with chronic occlusion of the left middle cerebral artery

The chronic occlusion of intracranial arteries generally has no or mild clinical symptoms,and the clinical symptoms of acute cerebral artery occlusion are mostly manifested as severe cerebral infarction symptoms,which often make early diagnosis difficult,thus losing the best treatment opportunity.Once cerebral infarction occurs,the consequences are difficult to recover.This is also an important reason for the high misdiagnosis rate and mortality of this disease.In this paper,the characteristics of the disease were analyzed to provide clinical reference.

Operative or Interventional Treatment in Infrainguinal Bypass Occlusion:Are There Predictive Factors Affecting Outcome?

Purpose: To evaluate outcome of interventional and surcigal treatment in infrainguinal bypass occlusion and to identify predictive factors affecting therapeutic success. Material and Methods: Over a period of three years 96 patients with infrainguinal bypass occlusion were included in this retrospective study. 52 patients were treated by catheter-directed thrombolysis and 44 patients by reconstructive vascular surgery. Results: 41 grafts could be reopened in thrombolytic group (78.8%), thrombolysis failed in 11 cases (21.2%). 34 grafts were treated successfully by reconstructive vascular surgery (77.3%), 10 grafts couldn’t be reopened or reoccluded within 30 days after surcical therapy. After a median observation time of 14.7 months 30 of 48 (62.5%) bypass grafts treated with intraarterial thrombolysis and 19 of 27 (70.4%) grafts treated with thrombectomy were overall patent. Limb salvage was 81.3% in thrombolytic group and 88.8% in surgery group. No predictive factors affecting outcome could be identified in both groups except the localization of the occluded graft (above/below knee). Conclusion: Infrainguinal bypass occlusion is a serious and challenging complication in vascular surgery. Our study showed similar results for both therapeutic strategies. Despite our data was retrospective with a small number of patients the localization of the occluded graft as predictive pretherapeutic factor was significant in thrombolytic and surgery group. Based on these scientific findings we established a guideline for choice of therapeutic treatment in our institution after searching current literature.

Prognostic factors for acute central retinal artery occlusion treated with hyperbaric oxygen:The Hong Kong study report number five

BACKGROUND Central retinal artery occlusion(CRAO)is a potentially blinding disease,and hyperbaric oxygen therapy(HBOT)is becoming increasingly popular with the support of scientific evidence.Despite the presence of various acute management measures,there is no clear evidence on the gold standard treatment for CRAO.AIM To identify factors and imaging parameters associated with good visual outcome,which guide ophthalmologists in the triage of CRAO patients for HBOT.METHODS Patients who suffered from CRAO and had a symptom onset≤6 h were recruited for a course of HBOT in a tertiary hospital after failing bedside treatment.Patient demographics,onset time,CRAO eye parameters,and past medical history were prospectively collected.Visual outcomes after HBOT were also analyzed.RESULTS A total of 26 patients were included;the female-to-male ratio was 1:1.6,and the mean age was 67.5 years±13.3 years(range 44–89 years).The mean duration of follow-up and mean visual acuity(VA)improvement were 10.0 mo±5.3 mo and 0.48 logarithm of minimal angle of resolution(logMAR)±0.57 logMAR(approx-imately 9 letters in ETDRS)(P=0.0001,Z=-3.67),respectively.The 1 mm zone of central macular thickness(CMT)on optical coherence tomography was not associated with VA changes(P=0.119);however,the 1-to-3 mm circular rim of CMT was fairly associated(P=0.02,Spearman's coefficient=0.45).Complete retinal perfusion time during fundus fluorescein angiography(FFA)was mode-rately associated(P=0.01,Spearman's coefficient=0.58)with visual outcome.

Analysis of The Impact of Interventional Nursing on The Therapeutic Effect, Negative Emotions, and Quality of Life of Patients Undergoing Cardiovascular and Cerebrovascular Interventional Therapy

Objective: To explore the impact of interventional nursing on the therapeutic effect, negative emotions, and quality of life of patients undergoing cardiovascular and cerebrovascular interventional therapy. Methods: A total of 106 patients who underwent cardiovascular and cerebrovascular interventional treatment were collected and randomly divided into Group A (control) and Group B (observation), with 53 cases each. Group A received the routine nursing intervention and Group B received the interventional nursing intervention. The clinical efficacy, complications, negative emotions, quality of life, and nursing satisfaction of the two groups of patients were evaluated. Results: The total clinical effective rate of Group B (52/98.12%) was higher than that of Group A (45/84.91%) (χ^(2)= 4.371, P < 0.05). The total incidence of complications in Group B (2/3.78%) was lower than that of Group A (9/16.98%) (χ^(2)= 4.970, P < 0.05). The self-rating anxiety (SAS) score and self-rating depression (SDS) of Group B were lower than those of Group A (P < 0.001). The quality of life of Group B was significantly higher than that of Group A (P < 0.001). The nursing satisfaction of group B (51/96.22%) was higher than that of group A (43/81.13%) (χ^(2)= 6.014, P < 0.05). Conclusion: In the care of patients undergoing cardiovascular and cerebrovascular interventional therapy, interventional nursing intervention effectively improved the patient’s clinical efficacy, reduced the incidence of complications, reduced negative emotions, improved the quality of life, and increased nursing satisfaction.

Mimicking aneurysm in a patient with chronic occlusion of the left middle cerebral artery:A case report

BACKGROUND With the popularization of various cerebrovascular imaging methods and increased attention to the field,more cerebrovascular diseases are being detected in asymptomatic patients.Different cerebrovascular diseases are typically isolated but occasionally occur simultaneously,causing difficulties in diagnosis and treatment.Morphological changes in the collateral circulation of blood vessels in chronic cerebral artery occlusion patients are slow and dynamic,intercepting morphological development at a specific moment.Excessive reliance on single imaging tests such as digital subtraction cerebral angiography(DSA)can lead to misdiagnosis.CASE SUMMARY We report a 52-year-old male who was admitted to our department for treatment of an unruptured aneurysm during a follow-up examination for brain trauma after 1 mo.Computed tomography(CT)scan was negative,but CT angiography(CTA)revealed a sac-like bulge at the bifurcation of the left middle cerebral artery.DSA revealed an unruptured aneurysm with unique scapular morphology.The stump of a middle cerebral artery occlusion was observed during exposure during aneurysm clipping surgery,and the diagnosis of chronic cerebral artery occlusion was confirmed intraoperatively.This case was confusing because of the peculiar morphology of the arterial stump and compensatory angiogenesis due to multiple cerebral artery stenoses observed on preoperative CTA and DSA.The surgery did not cause secondary damage to the patient,and medical treatment for risk factors was continued postoperatively.CONCLUSION Multiple cerebral arterial stenoses can occur in conjunction with aneurysms or arteriovenous malformations,and their unique morphology can lead to misdiagnosis.

Current interventional options for palliative care for patients with advanced-stage cholangiocarcinoma

Primary biliary tract tumors are malignancies that originate in the liver,bile ducts,or gallbladder.These tumors often present with jaundice of unknown etiology,leading to delayed diagnosis and advanced disease.Currently,several palliative treatment options are available for primary biliary tract tumors.They include percutaneous transhepatic biliary drainage(PTBD),biliary stenting,and surgical interventions such as biliary diversion.Systemic therapy is also commonly used for the palliative treatment of primary biliary tract tumors.It involves the administration of chemotherapy drugs,such as gemcitabine and cisplatin,which have shown promising results in improving overall survival in patients with advanced biliary tract tumors.PTBD is another palliative treatment option for patients with unresectable or inoperable malignant biliary obstruction.Biliary stenting can also be used as a palliative treatment option to alleviate symptoms in patients with unresectable or inoperable malignant biliary obstruction.Surgical interventions,such as biliary diversion,have traditionally been used as palliative options for primary biliary tract tumors.However,biliary diversion only provides temporary relief and does not remove the tumor.Primary biliary tract tumors often present in advanced stages,making palliative treatment the primary option for improving the quality of life of patients.

Intelligent diagnosis of retinal vein occlusion based on color fundus photographs

AIM:To develop an artificial intelligence(AI)diagnosis model based on deep learning(DL)algorithm to diagnose different types of retinal vein occlusion(RVO)by recognizing color fundus photographs(CFPs).METHODS:Totally 914 CFPs of healthy people and patients with RVO were collected as experimental data sets,and used to train,verify and test the diagnostic model of RVO.All the images were divided into four categories[normal,central retinal vein occlusion(CRVO),branch retinal vein occlusion(BRVO),and macular retinal vein occlusion(MRVO)]by three fundus disease experts.Swin Transformer was used to build the RVO diagnosis model,and different types of RVO diagnosis experiments were conducted.The model’s performance was compared to that of the experts.RESULTS:The accuracy of the model in the diagnosis of normal,CRVO,BRVO,and MRVO reached 1.000,0.978,0.957,and 0.978;the specificity reached 1.000,0.986,0.982,and 0.976;the sensitivity reached 1.000,0.955,0.917,and 1.000;the F1-Sore reached 1.000,0.9550.943,and 0.887 respectively.In addition,the area under curve of normal,CRVO,BRVO,and MRVO diagnosed by the diagnostic model were 1.000,0.900,0.959 and 0.970,respectively.The diagnostic results were highly consistent with those of fundus disease experts,and the diagnostic performance was superior.CONCLUSION:The diagnostic model developed in this study can well diagnose different types of RVO,effectively relieve the work pressure of clinicians,and provide help for the follow-up clinical diagnosis and treatment of RVO patients.

Imaging characteristics and treatment strategies for carotid artery occlusion caused by skull base fracture:Three case reports

BACKGROUND Traumatic internal carotid artery(ICA)occlusion is a rare complication of skull base fractures,characterized by high mortality and disability rates,and poor prognosis.Therefore,timely discovery and correct management are crucial for saving the lives of such patients and improving their prognosis.This article retrospectively analyzed the imaging and clinical data of three patients,to explore the imaging characteristics and treatment strategies for carotid artery occlusion,combined with severe skull base fractures.CASE SUMMARY This case included three patients,all male,aged 21,63,and 16 years.They underwent plain film skull computed tomography(CT)examination at the onset of their illnesses,which revealed fractures at the bases of their skulls.Ultimately,these cases were definitively diagnosed through CT angiography(CTA)examinations.The first patient did not receive surgical treatment,only anticoagulation therapy,and recovered smoothly with no residual limb dysfunction(Case 1).The other two patients both developed intracranial hypertension and underwent decompressive craniectomy.One of these patients had high intracranial pressure and significant brain swelling postoperatively,leading the family to choose to take him home(Case 2).The other patient also underwent decompressive craniectomy and recovered well postoperatively with only mild limb motor dysfunction(Case 3).We retrieved literature from PubMed on skull base fractures causing ICA occlusion to determine the imaging characteristics and treatment strategies for this type of disease.CONCLUSION For patients with cranial trauma combined with skull base fractures,it is essential to complete a CTA examination as soon as possible,to screen for blunt cerebrovascular injury.

Total suprarenal aortic occlusion with cardiac disease: a case series of three cases

Acute aortic occlusion(AAO)has been very rarely reported in the literature and is a potentially life-threatening emergency.[1-5]AAO mostly occurs in cardiac disease patients,[1-4,6,7]and leads to cardiac complications.[1,2,5,6]Suprarenal aortic occlusion(SAO)is a very rare type of AAO,and infrarenal aortic occlusion(IAO)accounts for 75.8%-97.8%.[1,3,5-7]SAO is different from IAO in some clinical manifestations,treatment strategies,and prognoses.[3,6-8]SAO with cardiac disease will make the condition more complex and could easily cause a delay in diagnosis and portend worse outcomes with amputation and mortality rates.[1,3,6]Early and fast diagnosis and positive revascularization treatment are necessary to prevent cases from becoming fatal.[1-3]Herein,we present a case series of SAO with cardiac disease.

The prognostic value of collateral circulation in coronary chronic total occlusion underwent percutaneous coronary intervention

BACKGROUND The prognostic value of coronary collateral circulation(CC)in patients undergoing chronic total occlusion(CTO)percutaneous coronary intervention(PCI)is underdetermined.The purpose of the study was to assess the prognostic value of current two CC grading systems and their association with long-term outcomes in patients with CTO underwent PCI.METHODS We consecutively enrolled patients with single-vessel CTO underwent PCI between January 2010 and December2013.All patients were categorized into well-developed or poor-developed collaterals group according to angiographic Werner's CC(grade 2 vs.grade 0–1)or Rentrop(grade 3 vs.grade 0–2)grading system.The primary endpoint was 5-year cardiac death.RESULTS Of 2452 enrolled patients,the overall technical success rate was 74.1%.Well-developed collaterals were present in686 patients(28.0%)defined by Werner's CC grade 2,and in 1145 patients(46.7%)by Rentrop grade 3.According to Werner's CC grading system,patients with well-developed collaterals had a lower rate of 5-year cardiac death compared with those with poordeveloped collaterals(1.6%vs.3.3%,P=0.02),those with suboptimal recanalization was associated with higher rate of 5-year cardiac death compared with optimal recanalization(4.7%vs.0.8%,P=0.01)and failure patients(4.7%vs.1.6%,P=0.12).However,the similar effect was not shown in Rentrop grading system.CONCLUSIONS In patients with the single-vessel CTO underwent PCI,well-developed collaterals by Werner's CC definition were associated with lower rate of 5-year cardiac death.Werner's CC grading system had a greater prognostic value than Rentrop grading system in patients with CTO underwent PCI.

Predictive value of neutrophil-to-lymphocyte ratio in coronary chronic total occlusion patients

BACKGROUND The neutrophil to lymphocyte ratio(NLR)has been reported as a novel predictor for atherosclerosis and car-diovascular outcomes.This study aimed to determine the effects of NLR on long-term clinical outcomes of chronic total occlusion(CTO)patients.METHODS A total of 670 patients with CTO who met the inclusion criteria were included at the end of the follow-up period.Patients were divided into tertiles according to their baseline NLR levels at admission:low(n=223),intermediate(n=223),and high(n=224).The incidence of major adverse cardiac events(MACEs)during the follow-up period,including all-cause death,nonfatal myocardial infarction(MI),or ischemia-driven revascularization,were compared among the three groups.RESULTS Major adverse cardiac events were observed in 27 patients(12.1%)in the low tertile,40(17.9%)in the intermediate tertile,and 61(27.2%)in the high NLR tertile(P<0.001).Kaplan-Meier analysis demonstrated a significantly higher incidence of MACE,ischemia-driven coronary revascularization,non-fatal MI,and mortality in patients within the high tertile than those in the low and intermediate groups(all P<0.001).Multivariable COX regression analysis showed that the high tertile of baseline NLR level showed a strong association with the risk of MACE(hazard ratio[HR]=2.21;95%confidence interval[CI]:1.21-4.03;P=0.009),ischemia-driven coronary revascularization(HR=3.19;95%CI:1.56-6.52;P=0.001),MI(HR=2.61;95%CI:1.35-5.03;P=0.043)and mortality(HR=3.78;95%CI:1.65-8.77;P=0.001).CONCLUSION Our findings suggest that NLR is an inexpensive and readily available biomarker that can independently pre-dict cardiovascular risk in patients with CTO.

Retinal vein occlusion coinciding with paracentral acute middle maculopathy in patient with menorrhagia causing life-threatening anemia

Dear Editor,We present two cases of retinal vein occlusion,one central retinal vein occlusion(CRVO)and one branch retinal vein occlusion(BRVO)respectively,coinciding with paracentral acute middle maculopathy(PAMM)on optical coherence tomography(OCT)in patients with menorrhagia causing life-threatening anemia.PAMM is considered a manifestation of acute ischemia affecting the deep macular capillary plexus.

Recanalization of anastomotic occlusion following rectal cancer surgery using a rendezvous endoscopic technique with transillumination:A case report

BACKGROUND Colorectal anastomotic occlusion is a serious complication of colorectal cancer surgery.Although several treatment strategies have been proposed,the mana-gement of anastomotic occlusion remains challenging.In this report,we present a case of anastomotic occlusion recanalization performed using a novel technique involving two endoscopes,one for radial incision and the other serving as a guide light.This novel technique offers significant advantages in terms of operational feasibility,reduced invasiveness,rapid recovery,and shortened hospital stay.CASE SUMMARY A 37-year-old man underwent low anterior resection and prophylactic double-lumen ileostomy for rectal cancer in June,2023.Two months later,complete anastomotic occlusion was observed on colonoscopy.Therefore,we developed a novel atresia recanalization technique.Two endoscopes were placed,one through the colonic anastomosis and the other through the anus.A radial incision was successfully made from the colonic side,guided by the light of the endoscope from the anal side.Atresia recanal-ization was performed within 20 minutes.Three weeks after recanalization,colonoscopy revealed that the diameter of the colorectal anastomosis was approximately 16 mm and the patient therefore underwent stoma reversal in September.During the follow-up period of approximately one year,the patient remained well and no stenosis or obstruction symptoms were observed.CONCLUSION Endoscopic atresia recanalization of colorectal anastomotic occlusion assisted by an opposing light source is safe and effective.

Dexamethasone implant for refractory macular edema secondary to diabetic retinopathy and retinal vein occlusion

AIM:To evaluate the efficacy,timing of retreatment and safety of dexamethasone(DEX)implant on macular edema(ME)secondary to diabetic retinopathy(DME)and retinal vein occlusion(RVO-ME)patients who were refractory to anti-vascular endothelial growth factor(VEGF)treatment.METHODS:This retrospective study included 37 eyes received at least one DEX implant treatment for DME or RVO-ME between January 1,2019,and January 1,2023.These refractory DME and RVO-ME cases received at least 5 anti-VEGF injections and failure to gain more than 5 letters or a significant reduction in central retinal thickness(CRT).The best corrected visual acuity(BCVA)and CRT were measured at baseline,and at 1,3,4 and 6mo post-DEX implant injection.Adverse events such as elevated intraocular pressure(IOP)and cataract were recorded.RESULTS:For RVO cases(n=22),there was a significant increase in BCVA from 0.27±0.19 to 0.35±0.20 at 6mo post-DEX injection(P<0.05)and CRT decreased from 472.1±90.6 to 240.5±39.0μm at 6mo(P<0.0001).DME cases(n=15)experienced an improvement in BCVA from 0.26±0.15 to 0.43±0.20 at 6mo post-DEX implant injection(P=0.0098),with CRT reducing from 445.7±55.7 to 271.7±34.1μm at 6mo(P<0.0001).Elevated IOP occurred in 45.9% of patients but was well-controlled with topical medications.No cases of cataract or other adverse events were reported.CONCLUSION:DEX implants effectively improve BCVA and reduce CRT in refractory DME and RVO-ME.Further research with larger cohorts and longer follow-up periods is needed to confirm these findings and assess long-term outcomes.

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.

Comparative Quantitative Analysis of Retinal Superficial Capillary Plexus in Patients with Retinal Vein Occlusion and Unaffected Fellow Eyes

Purpose: To evaluate optical coherence tomography angiography (OCT-A) data obtained from the superficial retinal capillary plexus of patients with retinal vein occlusion and comparative analysis with data registered from unaffected fellow eyes. Methods: The examined patients were classified into 2 groups: group 1—eyes with established retinal vein occlusion (n = 29) and group 2—unaffected fellow eyes of patients with retinal vein occlusion (n = 24). The scanning protocol “Angiography 3 × 3 mm” of Zeiss Cirrus HD-OCT 6000, AngioPlex Metrix was used to evaluate the retinal superficial capillary plexus. The analyzed parameters were vascular density and perfusion density, as well as the area, perimeter, and circularity of the foveolar avascular zone (FAZ). Results: The comparative analysis of FAZ parameters at the superficial capillary plexus (SCP) between group 1 (eyes with retinal vein occlusion) and group 2 (unaffected fellow eyes) showed significant results for the three parameters, respectively area (p = 0.003), perimeter (p ≤ 0.001), and circularity (p = 0.011) of FAZ. The comparative analysis of the vascular network at SCP in patients with diagnosed retinal vein occlusion and unaffected fellow eyes showed significant results for vascular density (VD) in the central (p = 0.038) and inner (p ≤ 0.001) zones as well as total VD (p ≤ 0.001) were statistically significant. Moreover, the results obtained in the study of vascular perfusion (VP) indicated significant results in the inner zone (p ≤ 0.001) and total VP (p = 0.001). Vascular perfusion in the central zone (p = 0.116) was the only parameter not to meet significant results. Conclusion: The current study observed a significant enlargement of the FAZ and loss of its circularity, along with a reduction in vascular network parameters at the superficial retinal capillary plexus level.

Lenvatinib,sintilimab combined interventional treatment vs bevacizumab,sintilimab combined interventional treatment for intermediate-advanced unresectable hepatocellular carcinoma

BACKGROUND Bevacizumab and sintilimab combined interventional treatment(BeSiIT)and L envatinib and sintilimab combined interventional treatment(LeSiIT)are two commonly used therapeutic regimens for intermediate-advanced hepatocellular carcinoma(HCC)in clinical practice.AIM To compare the clinical efficacy and safety of BeSiIT and LeSiIT for the treatment of intermediate and advanced HCC.METHODS Patients diagnosed with intermediate-advanced HCC and initially treated with BeSiIT or LeSiIT in the Tianjin Medical University Cancer Institute and Hospital between February 2020 and July 2021 were included.The primary endpoint was progression-free survival(PFS),and the secondary endpoints were overall survival(OS),objective response rate(ORR),disease control rate(DCR),conversion rate,and treatmentrelated adverse events.RESULTS Total 127 patients met the inclusion criteria and were divided into BeSiIT and LeSiIT groups.Twenty-eight and fifty patients in the BeSiIT and LeSiIT groups,respectively,were assessed after 1:2 propensity score matching.PFS and OS rates were not significantly different between the two groups.No significant variations were noted in ORRs or DCRs according to the Response Evaluation Criteria in Solid Tumors(RECIST),and modified RECIST.BeSiIT group showed a better conversion rate than the LeSiIT group(P=0.043).Both groups showed manageable toxicity profiles.Multivariate analysis showed that the independent factors associated with PFS were alphafetoprotein levels and carcinoembryonic antigen score.CONCLUSION In intermediate-to-advanced HCC,the BeSiIT and LeSiIT groups exhibited acceptable toxicities and comparable PFS,OS,and ORR.

Risk factors of non-arteritic anterior ischaemic optic neuropathy and central retinal artery occlusion

AIM:To investigate the difference in risk factors between non-arteritic anterior ischaemic optic neuropathy(NAION)and central retinal artery occlusion(CRAO)and develop a predictive diagnostic nomogram.METHODS:The study included 37 patients with monocular NAION,20 with monocular CRAO,and 24 with hypertension.Gender,age,and systemic diseases were recorded.Blood routine,lipids,hemorheology,carotid and brachial artery doppler ultrasound,and echocardiography were collected.The optic disc area,cup area,and cup-to-disc ratio(C/D)of the unaffected eye in the NAION and CRAO group and the right eye in the hypertension group were measured.RESULTS:The carotid artery intimal medial thickness(C-IMT)of the affected side of the CRAO group was thicker(P=0.039)and its flow-mediated dilation(FMD)was lower(P=0.049)than the NAION group.Compared with hypertension patients,NAION patients had higher whole blood reduced viscosity low-shear(WBRV-L)and erythrocyte aggregation index(EAI;P=0.045,0.037),and CRAO patients had higher index of rigidity of erythrocyte(IR)and erythrocyte deformation index(EDI;P=0.004,0.001).The optic cup and the C/D of the NAION group were smaller than the other two groups(P<0.0001).The diagnostic prediction model showed high diagnostic specificity(83.7%)and sensitivity(85.6%),which was highly related to hypertension,the C-IMT of the affected side,FMD,platelet(PLT),EAI,and C/D.CONCLUSION:CRAO patients show thicker C-IMT and worse endothelial function than NAION.NAION and CRAO may be related to abnormal hemorheology.A small cup and small C/D may be involved in NAION.The diagnostic nomogram can be used to preliminarily identify NAION and CRAO.
