Abstract:
Small bowel arteriovenous malformation (AVM) is a rare vascular lesion, which should be considered in patients presenting with gastrointestinal bleeding, as it is a high-flow arterial lesion that can cause life-threatening bleeding. Although a primary endoscopic examination is performed in cases of suspected small bowel bleeding, the diagnosis of the causal lesion is sometimes difficult. We are presenting a case of small bowel AVM that could not be diagnosed endoscopically but was successfully detected using multiphase CT images with an appropriate protocol. The AVM diagnosis was confirmed using digital subtraction angiography. An endovascular coil is placed in the draining vein as a surgical resection marker. The AVM was resected successfully without any complications.
摘要:
小肠动静脉畸形(AVM)是一种罕见的血管病变,这应该在出现消化道出血的患者中考虑,因为它是一种高流量动脉病变,可导致危及生命的出血。尽管在疑似小肠出血的病例中进行了一次内镜检查,病因病变的诊断有时很困难。我们正在介绍一例小肠AVM,该病例无法通过内窥镜诊断,但可以使用适当的协议使用多相CT图像成功检测到。使用数字减影血管造影证实了AVM的诊断。将血管内线圈放置在引流静脉中作为手术切除标记。成功切除AVM,无任何并发症。
