Dislocated thrombus aspiration with computer-assisted vacuum thrombectomy during endovascular aortic repair: a bailout procedure.

A 70-year-old woman was treated with thoracic endovascular aortic repair for an enlarging descending thoracic aortic aneurysm. Intraprocedural angiography after stentgraft positioning revealed superior mesenteric and right renal artery occlusion due to parietal thrombus displacement. This unusual complication was promptly treated with thrombus aspiration, which avoided visceral ischaemia by utilizing a minimally invasive technique. Treatment success was confirmed with intraprocedural angiography and computerized tomography a few days postoperatively.
