摘要
目的评价研究栓塞治疗下消化道出血的疗效及影响疗效的因素。方法急性下消化道大出血１１例，男６例，女５例。采用同轴导管法，当导管前端达到出血部位末级动脉弓前一级分支或以远时行栓塞治疗。结果１１例中，１０例成功，１例失败。１０例成功者均为栓后即刻止血，无肠坏死及其他并发症，随访１～１６个月无再出血。１例超选择性插管失败原因系失血性休克内科治疗时间过长无效，内脏血管收缩所致。结论在确认导管远端位置达到靶动脉末级动脉弓前一级分支或以远时，行栓塞治疗是安全、有效的。因为空肠、回肠及结肠动脉管径较细，且血管走形多呈钝角或近似直角，因此微导管的使用是栓塞治疗成功的前题。
Objective To evaluate the effectiveness and its relevent factors of transcatheter embolization for acute lower gastrointestinal hemorrhage. Methods Eleven patients with acute lower gastrointestinal hemorrhage were embolized using coaxial microcatheter. Embolization was started as soon as the tip of microcatheter was located in the first branch artery preterminal arcade or further where hemorrhage was identified. Results Ten of the eleven patients were treated successfully by this method, hemorrhage was stopped immediately, and there was no infarction of intestine and no recurrent hemorrhage in followup for 1-16 months. In one patient, super selective catheterization to permit embolization could not be achieved due to splanchnic vasospasm. Conclusions Transcatheter embolization for lower gastrointestinal hemorrhage is a safe and efficient therapeutic method if the catheter can get into the first branch artery preterminal arcades or further supplying the hemorrhagic area. The use of microcatheter is a prerequisite for successful treatment.
