Fenestrated and Branched Endovascular Treatment of Recurrent Visceral Aortic Patch Aneurysm after Open Thoracoabdominal Repair.

The most common visceral revascularization technique during open repair of thoracoabdominal aortic aneurysms (TAAA) is the "inclusion technique," but its main long-term drawback is that the retained portion of the diseased aorta might be prone to further dilatation, thus giving rise to a recurrent visceral aortic patch aneurysm. This brief report presents 4 consecutive cases of visceral aortic patch aneurysms treated by means of fenestrated and branched endovascular approach with custom-made endografts. The procedures were technically successful in all 4 patients and no major complications were recorded at 11.9 months of follow-up.
