Endovascular treatment of ruptured lobulated anterior communicating artery aneurysms:A retrospective study of 24 patients

BACKGROUND Lobulated intracranial aneurysm is a special type of aneurysm with at least one additional cyst in the neck or body of the aneurysm.Lobulated intracranial aneurysm is a complex aneurysm with complex morphology and structure and weak tumor wall,which is an independent risk factor for rupture and hemorrhage.Lobular aneurysms located in the anterior communicating artery complex account for 36.9%of all intracranial lobular aneurysms.Due to its special anatomical structure,both craniotomy and endovascular treatment are more difficult.Compared with single-capsule aneurysms,craniotomy for lobular intracranial aneurysms has a higher risk and complication rate.AIM To investigate the efficacy and safety of endovascular treatment for ruptured lobulated anterior communicating artery aneurysm(ACoAA).METHODS Patients with ruptured lobulated ACoAA received endovascular treatment in Sanming First Hospital Affiliated to Fujian Medical University from June 2020 to June 2022 were retrospectively included.Their demographic,clinical and imaging characteristics,endovascular treatment methods and follow-up results were collected.RESULTS A total of 24 patients with ruptured lobulated ACoAA were included,including 9 males(37.5%)and 15 females(62.5%).Their age was 56.2±8.9 years old(range 39-74).The time from rupture to endovascular treatment was 10.9±12.5 h.The maximum diameter of the aneurysms was 5.1±1.0 mm and neck width were 3.0±0.7 mm.Nineteen patients(79.2%)were double-lobed and 5(20.8%)were multilobed.Fisher's grade:Grade 2 in 16 cases(66.7%),grade 3 in 6 cases(25%),and grade 4 in 2 cases(8.3%).Hunt-Hess grade:Grade 0-2 in 5 cases(20.8%),grade 3-5 in 19 cases(79.2%).Glasgow Coma Scale score:9-12 in 14 cases(58.3%),13-15 in 10 cases(41.7%).Immediately postprocedural Raymond-Roy grade:grade 1 in 23 cases(95.8%),grade 2 in 1 case(4.2%).Raymond-Roy grade in imaging follow-up for 2 wk to 3 months:grade 1 in 23 cases(95.8%),grade 2 in 1 case(4.2%).Followup for 2 to 12 months showed that 21 patients(87.5%)had good functional outcomes(modified Rankin Scale score≤2),and there were no deaths.CONCLUSION Endovascular treatment is a safe and effective treatment for ruptured lobulated AcoAA.

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.

Application of multi-planar reconstruction technique in endovascular repair of aortic dissection

BACKGROUND Endovascular repair of aortic dissection is an effective method commonly used in the treatment of Stanford type B aortic dissection.Stent placement during the operation was one-time and could not be repeatedly adjusted during the operation.Therefore,it is of great significance for cardiovascular physicians to fully understand the branch status,position,angle,and other information regarding aortic arch dissection before surgery.AIM To provide more references for clinical cardiovascular physicians to develop treatment plans.METHODS Data from 153 patients who underwent endovascular repair of aortic dissection at our hospital between January 2021 and December 2022 were retrospectively collected.All patients underwent multi-slice spiral computed tomography angiography.Based on distinct post-image processing techniques,the patients were categorized into three groups:Multiplanar reconstruction(MPR)(n=55),volume reconstruction(VR)(n=46),and maximum intensity projection(MIP)(n=52).The detection rate of aortic rupture,accuracy of the DeBakey classification,rotation,and tilt angles of the C-arm during the procedure,dispersion after stent release,and the incidence of late complications were recorded and compared.RESULTS The detection rates of interlayer rupture in the MPR and VR groups were significantly higher than that in the MIP group(P<0.05).The detection rates of De-Bakey subtypesⅠ,Ⅱ,andⅢin the MPR group were higher than those in the MIP group,and the detection rate of typeⅢin the MPR group was significantly higher than that in the VR group(P<0.05).There was no statistically significant difference in the detection rates of typesⅠandⅡcompared to the VR group(P>0.05).The scatter rate of markers and the incidence of complications in the MPR group were significantly lower than those in the VR and MIP groups(P<0.05).CONCLUSION The application of MPR in the endovascular repair of aortic dissection has improved the detection rate of dissection rupture,the accuracy of anatomical classification,and safety.

Central nervous injury risk factors after endovascular repair of a thoracic aortic aneurysm with type B aortic dissection

Aortic dissection is the deadliest disease of the cardiovascular system.Type B aortic dissection accounts for 30%-60%of aortic dissections and is mainly treated by endovascular repair of thoracic endovascular aneurysm repair(TEVAR).However,patients are prone to various complications after surgery,with central nervous system injury being the most common,which seriously affects their prognosis and increases the risk of disability and death.Therefore,exploring the risk factors of central nervous system injury after TEVAR can provide a basis for its prevention and control.AIM To investigate the risk factors for central nervous system injury after the repair of a thoracic endovascular aneurysm with type B aortic dissection.METHODS We enrolled 306 patients with type B aortic dissection who underwent TEVAR at our hospital between December 2019 and October 2022.The patients were categorized into injury(n=159)and non-injury(n=147)groups based on central nervous system injury following surgery.The risk factors for central nervous system injury after TEVAR for type B aortic dissection were screened by comparing the two groups.Multivariate logistic regression analysis was performed.RESULTS The Association between age,history of hypertension,blood pH value,surgery,mechanical ventilation,intensive care unit stay,postoperative recovery times on the first day after surgery,and arterial partial pressure of oxygen on the first day after surgery differed substantially(P<0.05).Multivariate logistic regression analysis indicated that age,surgery time,history of hypertension,duration of mechanical ventilation,and intensive care unit stay were independent risk factors for central nervous system injury after TEVAR of type B aortic dissection(P<0.05).CONCLUSION For high-risk patients with central nervous system injury after TEVAR of type B aortic dissection,early intervention measures should be implemented to lower the risk of neurological discomfort following surgery in high-risk patients with central nervous system injury after TEVAR for type B aortic dissection.

Comprehensive classifications for the endovascular recanalization of vertebral artery stump syndrome

Background:and purpose:To share our single-center vertebral artery stump syndrome(VASS)treatment experience and assess the role of comprehensive classification based on anatomic development,proximal conditions,and distal conditions(PAD).Materials and methods:Data were retrospectively collected from patients who underwent endovascular thrombectomy(EVT)at the Stroke Center of the First Hospital of Jilin University between January 2016 and December2021.Among patients with acute ischemic stroke in the posterior circulation,those with acute occlusion of the intracranial arteries and occlusion at the origin of the vertebral artery confirmed by digital subtraction angiography were selected.The clinical data were summarized and analyzed.Results:Fifteen patients with VASS were enrolled in the study.The overall success rate of surgical recanalization was 80%.The successful proximal recanalization rate was 70.6%,and the recanalization rates for P1,P2,P3,and P4 were 100%,71.4%,50%,and 66.67%,respectively.The mean operation times for the A1 and A2 types were124 and 120 min,respectively.The successful distal recanalization rate was 91.7%,and the recanalization rates for types D1,D2,D3,and D4 were 100%,83.3%,100%,and 100%,respectively.Five patients experienced perioperative complications(incidence rate:33.3%).Distal embolism occurred in three patients(incidence rate:20%).No dissection or subarachnoid hemorrhage occurred in any patient.Conclusion:EVT is a technically feasible treatment for VASS,and comprehensive PAD classification can,to a certain extent,help initially estimate the difficulty of surgery and provide guidance for interventional procedures.

Endovascular Therapy of Internal Carotid Artery Tandem Occlusions and Literature Review

Acute large vessel occlusion is a common cause of acute ischemic stroke (AIS), with high rates of disability and lethality. The incidence of tandem occlusion of the internal carotid artery accounts for about 20% of patients with large vessel occlusion of the anterior circulation in acute ischemic stroke. The low rate of recanalization by intravenous thrombolysis in AIS due to internal carotid artery tandem occlusion, the poor establishment of collateral circulation within a short time, and the complex pathogenesis often suggest a poor prognosis for patients. Mechanical thrombectomy (MT) is beneficial for the opening of intracranial large vessel occlusion with internal carotid artery tandem occlusion, there are many problems regarding the emergency management of carotid artery occlusion or stenosis after mechanical thrombectomy, and there are currently no standardized treatment recommendations;The sequential approach to the management of carotid tandem occlusion, the timing of carotid stenting, and the use of antiplatelet agents remain controversial. The current state of research on carotid tandem occlusion is analyzed in the literature to promote clinical understanding of endovascular treatment for patients with acute ischemic stroke due to carotid tandem occlusion.

Endovascular Treatment of Ischemic Stroke due to Acute Carotid Dissection: A Report and Review of the Literature

The efficacy of endovascular therapy in patients with acute ischemic stroke due to tandem occlusion is comparable to that for isolated intracranial occlusion in the anterior circulation. Definitive treatment of carotid dissection-related strokes is currently unproved. The best endovascular technique in this setting remains to be established, but emergency carotid artery stenting (CAS) is frequently considered. We investigated the safety and efficacy of emergency CAS for carotid dissection in patients with acute stroke in current clinical practice.

Safety and Efficacy of Endovascular Aortic Repair for Abdominal Aortic Aneurysms with a Hostile Neck Anatomy

Objective This study aimed to investigate the safety and efficacy of endovascular aortic repair(EVAR)for the treatment of an abdominal aortic aneurysm(AAA)with a hostile neck anatomy(HNA).Methods From January 1,2015 to December 31,2019,a total of 259 patients diagnosed with an AAA who underwent EVAR were recruited into this study.Based on the morphological characteristics of the proximal neck anatomy,the patients were divided into the HNA group and the friendly neck anatomy(FNA)group.The patients were followed up for up to 4 years.Results The average follow-up time was 1056.1±535.5 days.Type I endoleak occurred in 4 patients in the HNA group,and 2 patients in the FNA group.Neither death nor intraoperative switch to open repair occurred in either group.The time of the operation was significantly longer in the HNA group(FNA vs.HNA,99.2±51.1 min vs.117.5±63.8 min,P=0.011).There were no significant differences in short-term clinical success rate(P=0.228)or midterm clinical success rate(P=0.889)between the two groups.The overall mortality rate was 10.4%,and Kaplan-Meier survival analysis indicated that the two groups had similar cumulative survival rates at the end of the follow-up period(P=0.889).Conclusion EVAR was feasible and safe in patients with an AAA with a proximal HNA.The early and midterm results were promising;however,further studies are needed to verify the long-term effectiveness of EVAR.

Morphological features and endovascular repair for type B multichanneled aortic dissection: A case report

BACKGROUND Among the various types of aortic dissection,multichanneled aortic dissection(MCAD)differs from classic double-channeled aortic dissection and involves the formation of an additional false lumen in the aortic wall or the flaps.It is considered a relatively rare condition with high perioperative mortality and morbidity.However,the morphological characteristic and the optimal therapeutic strategy for MCAD has not been fully determined.CASE SUMMARY A 64-year-old man presented to our hospital with severe epigastric abdominal pain radiating to the back that was associated with nausea without emesis.A computed tomography angiogram was performed that revealed a type B aortic dissection with multiple channels extending from the level of the left subclavian artery to the bilateral femoral arteries.We used a medical three-dimensional modeling(3D)modeling system to identify the location and extension of multiple lumens from different angles.It also precisely located the two primary entries leading to the false lumens,which helped us to exclude the two false lumens with one stent-graft.CONCLUSION By applying medical 3D modeling system,we discover the fragility of aortic wall and the collapse of true lumen caused by the multiple false lumens are the two morphological features of MCAD.

Subintimal recanalization for non-acute occlusion of intracranial vertebral artery in an emergency endovascular procedure:A case report

BACKGROUND Endovascular recanalization of non-acute intracranial artery occlusion is technically difficult,particularly when the microwire enters the subintima.Although the subintimal tracking and re-entry technique has been well established in the endovascular treatment of coronary artery occlusion,there is limited experience with its use in intracranial occlusion due to anatomical variations and a lack of dedicated devices.CASE SUMMARY A 74-year-old man was admitted to the hospital two days after experiencing acute weakness in both lower extremities,poor speech,and dizziness.After admission,imaging revealed acute ischemic stroke and non-acute occlusion of bilateral intracranial vertebral arteries(ICVAs).On the fourth day of admission,the patient's condition deteriorated and an emergency endovascular recanalization of the left ICVA was performed.During this procedure,a microwire was advanced in the subintima of the vessel wall and successfully reentered the distal true lumen.Two stents were implanted in the subintima.The patient's Modified Rankin Scale was 1 at three months postoperatively.CONCLUSION We present a technical case of subintimal recanalization for non-acute ICVA occlusion in an emergency endovascular procedure.However,we emphasize the necessity for caution when applying the subintimal tracking approach in intracranial occlusion due to the significant dangers involved.

Custom Made Fenestrated Stent Graft Collapse after Thoracic Endovascular Aortic Repair: A Case Report

We present a case of stent graft collapse after performing thoracic endovascular aortic repair with a custom-made fenestrated stent graft. The patient was a 70-year-old woman with an asymptomatic aneurysm of the distal aortic arch, and thoracic endovascular aortic repair was performed. The patient showed a blood pressure difference between the left arm and the right arm on postoperative day (POD) 17 prompting the performance of a chest computed tomography scan which revealed stent graft collapse. She then underwent staged debranching of thoracic endovascular aortic repair. Stent graft collapse is a rare but well-described complication of thoracic endovascular repair. Therefore, patients who undergo such a procedure should be carefully monitored for signs and symptoms, which suggest the possibility of stent collapse.

Carotid-subclavian bypass and endovascular aortic repair of Kommerell’s diverticulum with aberrant left subclavian artery:A case report

BACKGROUND Kommerell’s diverticulum(KD)with aberrant left subclavian artery is a rare congenital deformity and also has very little research literature about it(35%of case study).There are three types of aortic arch diverticulum.Even literature concerning the treatment options are limited.CASE SUMMARY We present a case report of a 50-year-old male with KD in the right aortic arch with aberrant left subclavian artery.We conducted a total endovascular repair procedure,which is innovative and will spread more light in the medical world.Our patient has no past medical history and is a non-smoker and non-alcoholic.Patient presented with shortness of breath,chest pain and dizziness for six months.Blood tests were done and computerized tomography(CT)angiogram of the chest confirmed the diagnosis,illustrating showed a 3.9 cm KD.On Day 1,the CT angiogram showed mild dilatation of the thoracic aorta,adjacent esophagus,trachea was compressed and displaced.Surgery was planned as the treatment modality.Carotid-Subclavian artery bypass and endovascular aortic repair was conducted.We used prolene 5-0 C1 sutures to precisely anastomose a 6-mm Dacron graft to the left subclavian artery.Haemostasis was secured and wounds were closed.Protamine was administered and patient was shifted to intensive care unit.Post-operative,patient responded favorably and was discharged.Regular follow-up is done.CONCLUSION The procedure we performed is novel.This will help the cardio-thoracic surgeons a better insight about the full procedures we conducted,thereby bringing more light and better treatment options in managing KD with aberrant subclavian artery.

Appearance of aseptic vascular grafts after endovascular aortic repair on[(18)F]fluorodeoxyglucose positron emission tomography/computed tomography

BACKGROUND Diagnosis of prosthetic vascular graft infection with[(18)F]fluorodeoxyglucose positron emission tomography/computed tomography(18F-FDG PET/CT)allows for early detection of functional changes associated with infection,based on increased glucose utilization by activated macrophages and granulocytes.Aseptic vascular grafts,like all foreign bodies,can stimulate an inflammatory response,which can present as increased activity on 18F-FDG PET/CT.Consequently,distinguishing aseptic inflammation from graft infection,though important,can be difficult.In the case of endovascular aneurysm repair(EVAR),a minimally invasive procedure involving the transfemoral insertion of an endoprosthetic stent graft,the normal postoperative appearance of these grafts on 18F-FDG PET/CT can vary over time,potentially confounding study interpretation.AIM To investigate the visual,semiquantitative,and temporal characteristics of aseptic vascular grafts in patients status post EVAR.METHODS In this observational retrospective cohort study,patients with history of EVAR who underwent 18F-FDG PET/CT for indications other than infection were identified retrospectively.All patients were asymptomatic for graft infection-no abdominal pain,fever of unknown origin,sepsis,or leukocytosis-at the time of imaging and for≥2 mo after each PET/CT.Imaging studies such as CT for each patient were also reviewed,and any patients with suspected or confirmed vascular graft infection were excluded.One hundred two scans performed on 43 patients(34 males;9 females;age=77±8 years at the time of the final PET/CT)were retrospectively reviewed.All 43 patients had an abdominal aortic(AA)vascular graft,40 patients had a right iliac(RI)limb graft,and 41 patients had a left iliac(LI)limb graft.Twentytwo patients had 1 PET/CT and 21 patients had from 2 to 9 PET/CTs.Grafts were imaged between 2 mo to 168 mo(about 14 years)post placement.Eight grafts were imaged within 6 mo of placement,including three that were imaged within three months of placement.The mean interval between graft placement and PET/CT for all 102 scans was 51±39 mo.PET/CT data was reconstructed with region-of-interest analysis of proximal,mid and distal portions of the grafts and background ascending aorta.Maximum standardized uptake value(SUVmax)was recorded for each region.SUVmax-to-background uptake ratios(URs)were calculated.Visual assessment was performed using a 2-pattern grading scale:Diffuse(homogeneous uptake less than liver uptake)and focal(one or more areas of focal uptake in any part of the graft).Statistical analysis was performed.RESULTS In total,there were 306 AA grafts,285 LI grafts,282 RI grafts,and 306 ascending aorta background SUVmax measurements.For all 102 scans,mean SUVmax values for AA grafts were 2.8-3.0 along proximal,mid,and distal segments.Mean SUVmax values for LI grafts and RI grafts were 2.7-2.8.Mean SUVmax values for background were 2.5±0.5.Mean URs were 1.1-1.2.Visual analysis of the scans reflected results of quantitative analysis.On visual inspection,98%revealed diffuse,homogeneous 18F-FDG uptake less than liver.Graft URs and visual pattern categories were significantly associated for AA graft URs(F-ratio=21.5,P<0.001),LI graft URs(F-ratio=20.4,P<0.001),and RI graft URs(F-ratio=30.4,P<0.001).Thus,visual patterns of 18F-FDG uptake corresponded statistically significantly to semiquantitative URs.The age of grafts showing focal patterns was greater than grafts showing diffuse patterns,87±89 vs 50±37 mo,respectively(P=0.02).URs were significantly associated with graft age for AA grafts(r=0.19,P=0.001).URs were also significantly associated with graft age for LI grafts(r=0.25,P<0.0001),and RI grafts(r=0.31,P<0.001).Quartiles of similar numbers of graft(n=25-27)grouped by graft age indicated that URs were significantly higher for 4th quartile vs 2nd quartile URs(F-ratio=19.5,P<0.001).When evaluating URs,graft SUVmax values within 10%-20%of the ascending aorta SUVmax is evident in aseptic grafts,except for grafts in the oldest quartiles.In this study,grafts in the oldest quartiles(>7 years post EVAR)showed SUVmax up to 30%higher than the ascending aorta SUVmax.CONCLUSION Characteristics of an aseptic vascular stent graft in the aorta and iliac vessels on 18F-FDG PET/CT include graft SUVmax values within 10%-20%of the ascending aorta background SUVmax.The SUVmax of older aseptic grafts can be as much as 30%above background.The visual uptake pattern of diffuse,homogeneous uptake less than liver was seen in 98%of aseptic vascular grafts,making this pattern particularly reassuring for clinicians.

脑血容量指数预测急性缺血性卒中患者血管内治疗远期预后的价值分析
