In this article, a novel technique for the treatment of ruptured abdominal aortic aneurysm secondary to proximal type 1 endoleak as a result of progressive neck dilatation after endovascular aneurysm repair is reported. A 74-year-old man with multiple comorbidities including severe ischemic heart disease, congestive cardiac failure, and chronic renal failure presented with a ruptured abdominal aortic aneurysm. He had an infrarenal endovascular aneurysm repair performed in 1999 and had subsequently developed a proximal type 1 endoleak. At open laparotomy, the placement of 4 nylon ties around the infrarenal aneurysm neck to refashion a seal and exclude the sac from systemic pressurization effectively treated the rupture. In the high-risk patient, ruptured proximal type 1 endoleak can be successfully treated with external banding avoiding the potential morbidity seen with the aortic clamping and blood loss of open conversion.
