Transcatheter embolization was performed in 7 patients with lower gastrointestinal bleeding. Hemorrhage was controlled in each of the 5 actively and massively bleeding patients but recurred after several months in 2 patients who had bled intermittently from vascular dysplasias. The authors recommend preoperative angiographic localization of the bleeding site in almost all cases of major lower gastrointestinal bleeding. When the cause and bleeding site have been identified, it seems reasonable to exploit the therapeutic potential of the angiographic catheter already in place: indeed, surgery may be obviated. If embolism fails or ischemic sequelae develop, partial colectomy can still be performed. Further long-term follow-up will be necessary before the role of transcatheter embolization can be definitively assessed.
对7例下消化道出血患者进行了经导管栓塞治疗。5例活动性大出血患者的出血均得到控制，但2例因血管发育异常而间歇性出血的患者在数月后出血复发。作者建议，在几乎所有主要的下消化道出血病例中，术前应对出血部位进行血管造影定位。当明确病因和出血部位后，利用已置入的血管造影导管进行治疗似乎是合理的：实际上，可以避免手术。如果栓塞失败或出现缺血性后遗症，仍可进行部分结肠切除术。在最终评估经导管栓塞治疗的作用之前，有必要进行进一步的长期随访。
