Background-Fenestrated endovascular repair of abdominal aortic aneurysms has been proposed as an alternative to open surgery for juxtarenal and pararenal abdominal aortic aneurysms. At present, the evidence base for this procedure is predominantly limited to single-center or single-operator series. The aim of this study was to present nationwide early results of fenestrated endovascular repair in the United Kingdom. Methods and Results-All patients who underwent fenestrated endovascular repair between January 2007 and December 2010 at experienced institutions in the United Kingdom(Ͼ10 procedures) were retrospectively studied by use of the GLOBALSTAR database. Site-reported data relating to patient demographics, aneurysm morphology, procedural details, and outcome were recorded. Data from 318 patients were obtained from 14 centers. Primary procedural success was achieved in 99% (316/318); perioperative mortality was 4.1%, and intraoperative target vessel loss was observed in 5 of 889 target vessels (0.6%). The early reintervention (Ͻ30 days) rate was 7% (22/318). There were 11 deaths during follow-up; none were aneurysm-related. Survival by Kaplan-Meier analysis was 94% (SE 0.01), 91% (0.02), and 89% (0.02) at 1, 2, and 3 years, respectively. Freedom from target vessel loss was 93% (0.02), 91% (0.02), and 85% (0.06), and freedom from late secondary intervention (Ͼ30 days) was 90% (0.02), 86% (0.03), and 70% (0.08) at 1, 2, and 3 years. Conclusions-In

The treatment of chronic type B aortic dissections remains challenging and controversial. Currently most centers advocate open or endovascular intervention for patients with evidence of malperfusion, rupture or impending rupture, continued pain, or aneurysm formation. Regardless of the type of intervention, the incidence of complications or death remains high, even when undertaken in an elective setting. The standard endovascular treatment usually involves placement of a stent graft into the true lumen of the dissection in an effort to exclude the false lumen. This case report describes the placement of a branched stent graft into the false lumen of a patient with chronic type B dissection to encourage exclusion and thrombosis of the true lumen whilst maintaining flow to all visceral vessels.
