Open conversion after previous endovascular treatment of a thoracoabdominal aneurysm with a branched thoracoabdominal stent graft (BEVAR). (A) Preoperative CTA showing BEVAR with bridging stents for celiac trunk, superior mesenteric artery, and right renal artery. The left renal artery was occluded during the index procedure. Despite the endovascular treatment, a progressive enlargement of the thoracoabdominal aneurysm (16 cm) was reported (dotted circles). (B) Intraoperative photographs showing thoracoabdominal aortic repair with a multibranched surgical prosthesis (see text).
