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.
我们报告了两名患有危及生命的大量下消化道出血且伴有局部晚期宫颈癌的患者。选择性盆腔动脉造影显示，一名患者的出血部位源于右髂内动脉假性动脉瘤，与乙状结肠存在瘘管相通；另一名患者的出血部位源于左髂内动脉并进入直肠。随后，对一名患者采用球囊闭塞法进行经导管栓塞治疗，对另一名患者采用弹簧圈栓塞法进行治疗。对于出现下消化道出血的盆腔癌患者，也应对髂动脉进行评估。
