Introduction. This study analyzed the patient outcomes following endovascular aortic aneurysm repair (EVAR) for infrarenal aortic pathologies with very narrow aortic bifurcations using the AFX stent graft. Methods. The data was retrieved from the archived medical records of 35 patients treated for abdominal aortic aneurysm (AAA) (48.6%) or penetrating aortic ulcer (PAU) (51.4%) with very narrow aortic bifurcation between January 2013 and May 2020. Patient survival, freedom from endoleak (EL), and limb occlusion were estimated applying the Kaplan–Meier method. Results. The mean follow-up time was 20.4 ± 22.8 months. The mean aortic bifurcation diameter was 15.8 ± 2.2 mm . Technical success was 100%, and no procedure-related deaths occurred. Two type II ELs occurred within 30-day follow-up. We observed one common iliac artery stenosis at four months and one type III EL at 54 months in the same patient, both of which required re-intervention. Overall patient survival was 95 ± 5 % (AAA: 100%; PAU: 89 ± 10 % ), freedom from limb occlusion was 94 ± 5 % (AAA: 91 ± 9 % ; PAU: 100%), freedom from type II EL was 94 ± 4 % (AAA: 88 ± 8 % ; PAU: 100%), and freedom from EL type III was 83 ± 15 % (AAA: 80 ± 18 % ; PAU: 100%) at the end of the follow-up period. Conclusions. Very narrow aortic bifurcations may predispose patients to procedure-related complications following EVAR. Our results suggest a safe use of the AFX stent graft in such scenarios. The overall short- and long-term procedure-related patient outcomes are satisfying albeit they may seem superior for PAU when compared to AAA.
Российский Онкологический Научный центр им. Н.Н. Блохина РАМН, г. Москва В статье представлен обзор современной мировой литературы по проблеме реконструкции трахеи при ее поражении п ервичными опухолями и метастазами. Проблема восстановления целостности дыхательного пути после протяженных резекций трахеи не решена и сохраняет свою актуальность. Существует большое количество операций, эффективных при необходимости устранения малых дефектов. Однако попытки замещения протяженных циркулярных дефектов трахеи после резекции при опухолевом поражении в клинической практике остаются неудачными.
