Ruptured thoracoabdominal aneurysm treatment with modified chimney stent graft.

A 76-year-old woman presented with symptomatic contained-ruptured thoracoabdominal aneurysm at the level of the superior mesenteric artery (SMA) and the hepatic artery origin from the SMA. The chimney technique for celiac trunk, SMA, and right renal artery (periscope configuration) was performed. An endovascular leak from the distal landing zone of the SMA stent graft was treated using a second modified stent graft with the SMA branches preservation. The 18-month follow-up computed tomography angiography demonstrated the aneurysm exclusion, no endovascular leak, and visceral and renal arteries patency.
