Abstract
Purpose: To describe a side-branched modular endograft system that provides adequate visceral artery perfusion with perfect seal during thoracoabdominal aortic aneurysm (TAAA) repair. Case Report: A 76-year-old man with a 57-mm TAAA involving the celiac artery was treated with a customized Talent endograft consisting of a 46-mm × 18-cm stented main body and a 6-mm × 30-mm nonstented Dacron side branch. The graft was delivered through a surgical exposure of the left common femoral artery. A 6-mm × 10-cm Hemobahn stent-graft was introduced in the 30-mm side branch from the aorta to the celiac trunk through a long 8-F sheath via the left brachial artery. The patient recovered uneventfully except for a mild reactive inflammatory syndrome. Postoperative computed tomography demonstrated total exclusion of the TAAA sac and good antegrade perfusion of the celiac and superior mesenteric arteries, which has been maintained at the 6-month follow-up. Conclusions: Endovascular treatment of TAAA is feasible with further technical refinements of available technology.
