Objective:To evaluate the safety and effectiveness of physician modified stent grafts technique and in situ fenestration technique for reconstructing the left subclavian artery in endovascular repair of thoracic aortic lesions with insufficient proximal landing area.Methods:A retrospective analysis was conducted on the clinical data of 75 patients with aortic arch lesions treated with physician modified stent grafts and in situ fenestration techniques at the Interventional Diagnosis and Treatment Department of Beijing Anzhen Hospital affiliated with Capital Medical University from November 2021 to March 2024. Among them, 52 patients received within physician modified stent grafts (PMSGs group) and 23 patients received in situ fenestration (ISF group). Based on two fenestration techniques, to analyze the technical success rate of endovascular repair in reconstructing the left subclavian artery in the perioperative and early following up adverse events both groups.Results:The success rate of PMSGs group technique was 92.31% (48/52), while the success rate of ISF technique was 91.30%(21/23). In the PMSGs group, there was 1 case of TypeⅠa endoleak and 3 cases of TypeⅠc endoleak immediately during endovascular repair; There was 1 case of TypeⅠa endoleak and 1 case of vascular injury in the ISF group immediately during endovascular repair. One case of perioperative cerebral infarction and one case of transient blindness occurred in the PMSGs group; One case of transient blindness and 1 case of brachial artery thrombosis occurred in the perioperative period in the ISF group. During the follow-up period, there was 1 case of distal dissection aneurysm formation in the PMSGs group, and 3 cases of minor typeⅠc endoleak were found after 3 months; One case of subclavian artery stent occlusion and 2 cases of minor typeⅠc endoleak occurred in the ISF group 6 months later. There were no cases of aortic-related deaths during the follow-up period in both groups. There was no statistically significant difference in the technical success rate, incidence of adverse events during the perioperative period and follow-up period, and re-intervention rate between the two groups. The average fluoroscopy time consumed in the ISF group was significantly higher than that in the PMSGs group (34.57 min vs. 21.42 min, P<0.001), but the average hospitalization time in the PMSGs group was significantly higher than that in the ISF group (9.33 days vs. 4.71 days, P<0.001). Conclusion:PMSGs and ISF techniques for reconstructing the left subclavian artery in the treatment of thoracic aortic arch lesions showed good safety and effectiveness. The appropriate fenestration technique selected based on aorta arch anatomical and lesion conditions could achieve satisfactory efficacy in short-term, but long-term effects need to be further observed.

Objective:To report a single-center experience with the Cordis Incraft endograft with low-profile in abdominal aortic aneurysms (AAAs) with severe infrarenal neck.Methods:All patients underwent EVAR with Incraft stent grafts between September 2019 and September 2022, were prospectively enrolled, and retrospectively analyzed. Anatomical details of the proximal aortic neck were evaluated, divided into the severe infrarenal neck (SIN, 13 cases) and normal infrarenal neck (NIN, 50 cases) groups. Early endpoints were intraoperative unplanned cuff or coil embolism, technical success (TS), 30-day morbidity/mortality, and reinterventions. Follow-up endpoints were occurrence of endoleaks, endograft migration, branch stent/ iliac stent-graft stenosis or occlusion, reintervention. The postoperative endoleak, aneurysm sac shrinkage, patency of iliac stent-graft/branch stent, and freedom from reinterventions between the two groups were compared.Results:A total of sixty-three patients were enrolled in this trial, all of whom were successfully treated. There was no significant difference in patient and lesion characteristics, excluding aneurysm neck length, neck angle and maximum aneurysm sac diameter. Proximal aneurysm neck length was shorter in the SIN group [(9.9±8.3)mm vs. (29.6±12.3)mm, P<0.001] and the neck angle was more tortile in the SIN group [(39.1±30.4)°vs.(25.1±15.4)°, P=0.036], as well maximum sac diameter was larger in the SIN group [(57.5±13.4)mm vs. (45.5±12.4)mm, P=0.016]. Although the results showed no differences between the two groups regarding the oversize rate of the main body stent graft, endoleak in operative and perioperative period, as well the hospital stay, the operative time was significantly longer in the SIN group [(96.36±31.83)min vs. (63.58±26.68)min, P=0.001]. Over the 3 years of follow-up (median time, 18 months), there were significant differences between the two groups regarding the complication occurrence of endoleak, renal stent or iliac stent-graft stenosis/occlusion ( P=0.012), and reintervention ( P=0.044). Conclusion:Data from this trial demonstrated excellent early and mid-term outcomes of EVAR using Incraft stent grafts, including severe infrarenal neck, with acceptable safety and efficacy in the short and middle terms.
