title: Aortic endograft thrombosis after colorectal surgery in lithotomy position.
abstract: Aortic endograft limb occlusion is a serious complication after endovascular abdominal aortic aneurysm repair. We describe a yet unreported cause of endograft limb occlusion, the lithotomy position. Two patients with abdominal aortic aneurysm and colorectal cancer underwent an initial endovascular repair followed by cancer resection in the lithotomy position. Aortic endograft limb occlusion occurred in both patients immediately after the cancer operation. Percutaneous rheolytic thrombectomy was performed successfully in both patients. Pelvic surgery requiring the lithotomy position should be performed with caution in patients with aortic endografts, because it can result in endograft occlusion.
