CO(2) cavography is well tolerated, safe, and adequate for identification of the parameters necessary for filter deployment. It is especially valuable in patients with a history of reaction to iodinated contrast material or renal insufficiency.

We report an unusual case of profuse, sporadic hemorrhage from a chronically infected perineal wound after an abdominoperineal resection. Surgical exploration and angiography on two occasions failed to identify the source of bleeding. A pseudoaneurysm of the internal iliac artery was eventually identified with a provocative angiogram using tissue plasminogen activator. This aneurysm was successfully treated with embolization with coils.
