This is a retrospective study to evaluate our early experience of using selective microcoil embolization in patients who had gastrointestinal (GI) haemorrhage. From December 2002 to December 2003, six patients with GI haemorrhage (upper GI, n = 1; lower GI, n = 5) underwent superselective microcoil embolization. Microcatheters were used to carry out embolizations in branches of the superior mesenteric artery. Microcoils were used in five patients and a combination of microcoils and embolospheres was used in one patient. Technical success (bleeding target devascularization) was achieved in all patients who showed active bleeding at the time of angiography. Two patients had recurrent bleeding within 24 h of embolization, of which one (16.7%) died. The other patient did not require active intervention as bleeding was minimal and resolved with conservative management. Satisfactory clinical success (no rebleeding after 30 days) was achieved in five patients. No clinical signs and symptoms of bowel ischaemia occurred in these patients. Follow-up colonoscopy carried out in two patients did not show any signs of ischaemia in the affected bowel segments. Superselective microcoil embolization is an effective and safe method of controlling and arresting bleeding in GI haemorrhage.
这是一项回顾性研究，旨在评估我们在胃肠道（GI）出血患者中使用选择性微线圈栓塞术的早期经验。2002年12月至2003年12月，6例胃肠道出血患者（上消化道出血1例，下消化道出血5例）接受了超选择性微线圈栓塞术。使用微导管对肠系膜上动脉分支进行栓塞。5例患者使用了微线圈，1例患者使用了微线圈和栓塞球囊的组合。在血管造影时显示有活动性出血的所有患者中均实现了技术成功（出血目标血管去血管化）。2例患者在栓塞后24小时内出现复发性出血，其中1例（16.7%）死亡。另一例患者因出血极少且通过保守治疗得以缓解，无需积极干预。5例患者取得了满意的临床成功（30天后无再出血）。这些患者未出现肠道缺血的临床体征和症状。对2例患者进行的随访结肠镜检查未显示受影响肠段有任何缺血迹象。超选择性微线圈栓塞术是控制和止住胃肠道出血的一种有效且安全的方法。
