Abstract
In February 2011, a male patient in his 60's underwent a low anterior resection and lateral lymph node dissection for lower rectal cancer. Due to large intestinal obstruction from local recurrence, an abdominoperineal resection was performed 5 years 8 months after his first surgery. Inflammation of the pelvic dead space persisted, requiring drainage after the surgery. Although bloody discharge was observed on the 12th and 30th postoperative day, the source of bleeding was not identified on contrast-enhanced CT. On the 35th postoperative day, the patient suddenly lost 700 mL of blood via the abdominal drain and perineal wound. Urgent angiography revealed an aneurysm on the branch of the left iliac artery. Therefore, transcatheter arterial embolization was performed for hemostasis. Infectious complications associated with surgery for locally recurrent rectal cancer frequently occur due to impaired tissue blood flow. This case highlights the importance of paying close attention to the possibility of infectious pseudoaneurysm.
