Fenestrated Stent Grafting for Short-necked and Juxtarenal Abdominal Aortic Aneurysm: An 8-Year Single-centre Experience

摘要: Abstract Objectives To present an 8-year clinical experience in the endovascular treatment of short-necked and juxtarenal abdominal aortic aneurysm (AAA) with fenestrated stent grafts. Methods At our tertiary referral centre, all patients treated branched grafts have been enrolled investigational device protocol database. Patients or AAA managed repair (F-EVAR) between November 2001 April 2009 were retrospectively reviewed. at other hospitals under supervision main author excluded from study. for suprarenal thoraco-abdominal aneurysms also excluded. All used customised based on Zenith system. Indications repair, operative postoperative mortality morbidity evaluated. Differences groups determined using analysis variance P Results One hundred (87 males/13 females) a median age 73 years (range, 50–91 years) during study period; this included 16 after previous open surgery EVAR. Thirty-day was 1%. Intra-operative conversion to needed one patient. Operative visceral vessel perfusion rate 98.9% (272/275). Median follow-up 24 months 1–87 months). Twenty-two died follow-up, unrelated. No ruptured. Estimated survival rates 1, 2 and 5 90.3 ± 3.1%, 84.4 4.0% 58.5 8.1%, respectively. Cumulative branch patency 93.3 1.9% years. Visceral artery occlusions occurred within first 2 Four renal fractures observed, which three associated occlusion. Twenty-five had increase serum creatinine more than 30%; two them required dialysis. In general, mean sac size decreased significantly (P Conclusions Fenestrated grafting appears safe effective longer term. Renal function deterioration, however, is major concern.
