ABSTRACT
OBJECTIVE:
Despite numerous recent pivotal and small-scale trials, real-world endovascular management of juxtarenal aneurysms (JRA), suprarenal aneurysms (SRA), and thoracoabdominal aortic aneurysms (TAAA) remains challenging without consensus best practices. This study evaluated the mortality, graft patency, renal function, complication, and reintervention rates for fenestrated and parallel endografts in complex aortic aneurysms repairs.METHODS:
This retrospective review of consecutive included patients with JRA, SRA, or TAAA who underwent complex endovascular repair from August 2014 to March 2017 at one high-volume institution. Treatment modality was a single surgeon decision based on patients anatomy and the urgency of the repair. Patient demographics, hospital course, and follow-up visits inclusive of imaging were analyzed. Ruptured aneurysms were excluded. Survival rates and outcomes were determined using the Kaplan-Meier method with log-rank tests.RESULTS:
Seventy complex endovascular aortic repairs were performed; 38 patients with TAAA were treated with snorkel/sandwich parallel endografts (21 celiac, 28 superior mesenteric arteries, 58 renal arteries) and 32 patients with JRA/SRA were treated by fenestrated endovascular aneurysm repair (FEVAR) with 94 total fenestrations (2 celiac, 30 SMA, 62 renal). The mean patient age was 74.8 ± 10.0 years. Sixty percent were male, and the mean aortic aneurysm diameter was 6.0 ± 1.4 cm. Perioperative mortality was 3.1% (1/32) for FEVAR compared with 2.6% (1/38) for parallel endografts (P = .9). All-cause reintervention rates were 15.6% in FEVAR (5/32) vs 23.6% with parallel endografts (9/38; P = .4). Branch reintervention rates per each branch endograft were 4.3% for FEVAR (4/94; 2 renal stent occlusions, 1 colonic ischemia without technical issue found on reintervention, 1 perinephric hematoma) vs 3.7% for parallel endografts (4/107; 2 renal and 1 celiac stent thromboses, and 1 renal stent kink; P = .41). The endograft branch thrombosis rate was 2.1% in FEVAR (2/94) vs 2.7% in parallel endografts (3/109; P = .77). Reinterventions owing to endoleaks were performed in five patients (2 type I, 2 type III, and 1 gutter endoleak; 13.1%) with parallel grafts vs no endoleak reinterventions in FEVAR. The overall survival and freedom from aneurysm-related mortality at 24 months was 78% and 96.9% in FEVAR vs 73% and 93.4% for parallel endografts (P = .8 and P = .6). The median follow-up was 12 months (range, 1-32 months).CONCLUSIONS:
Parallel and fenestrated endografts have acceptable and comparable mortality and patency rates in endovascular treatment of JRA, SRA, and TAAA. This study reaffirms that parallel endografts are a safe and viable alternative to fenestrated devices for complex aortic aneurysmal disease despite often treating more urgent patients and more complicated anatomy unable to be treated with FEVAR.Palavras-chave
