title: Transcatheter treatment of life-threatening lower gastrointestinal bleeding due to advanced pelvic malignancy.
abstract: We present two patients with life-threatening, massive, lower gastrointestinal (GI) bleeding and locally advanced cervical carcinoma. Selective pelvic arteriography demonstrated that the site of bleeding originated from a pseudoaneurysm of the right internal iliac artery with fistulous communication to the sigmoid colon in one patient and from the left internal iliac artery into the rectum in the second patient. Transcatheter embolotherapy was then performed using balloon occlusion in one patient and coil embolization in the second patient. The iliac arteries should also be evaluated in patients with pelvic cancer who present with lower GI bleeding.
