TRANSCATHETER TREATMENT OF LIFE-THREATENING LOWER GASTROINTESTINAL-BLEEDING DUE TO ADVANCED PELVIC MALIGNANCY

We present two patients with life-threatening, massive, lower gastroin testinal (GI) bleeding and locally advanced cervical carcinoma. Select ive pelvic arteriography demonstrated that the site of bleeding origin ated from a pseudoaneurysm of the right internal iliac artery with fis tulous communication to the sigmoid colon in one patient and from the left internal iliac artery into the rectum in the second patient. Tran scatheter embolotherapy was then performed using balloon occlusion in one patient and coil embolization in the second patient. The iliac art eries should also be evaluated in patients with pelvic cancer who pres ent with lower GI bleeding.
