Fenestrated endovascular repair for juxtarenal aortic aneurysm.
BACKGROUND
The outcome of fenestrated endovascular aneurysm repair (F-EVAR) was evaluated.


METHODS
Between February 2003 and December 2006, 45 patients (median age 73 (range 53-85) years) underwent primary (41) or secondary (four) F-EVAR for an abdominal aortic aneurysm with infrarenal neck anatomy unsuitable for a standard stent-graft. Median aneurysm diameter was 68 (range 55-100) mm and median infrarenal aortic neck length was 6 (range 0-13) mm. Customized fenestrated Zenith stent-grafts were employed in all procedures, incorporating fenestrations to preserve flow into renal (80), superior mesenteric (35) and coeliac (two) arteries. Eighty-two target vessels were stented (61 bare metal, 21 covered).


RESULTS
All aneurysms were isolated successfully, with preservation of the target vessels. One accessory renal artery was lost. One patient died after 5 days from myocardial infarction, and another at 3 months from multiorgan failure secondary to atheroembolism. At median follow-up of 24 (range 1-48) months, all aneurysms were stable or shrinking, with no late ruptures or graft-related endoleaks. Six patients required a secondary intervention. The primary vessel patency rate was 96.6 per cent. There were four late deaths, unrelated to the aneurysm.


CONCLUSIONS
F-EVAR enabled successful treatment of juxtarenal aortic aneurysm with a low complication rate.
