An arteriovenous fistula (AVF) is an uncommon sequela of spontaneous arterial aneurysm rupture into the adjacent venous system. We describe the case of a 74-year-old patient who underwent endovascular treatment of a right iliac AVF caused by a ruptured common iliac artery (CIA) aneurysm and a distal left CIA aneurysm. Surgery preserved the lumbar and inferior mesenteric arteries because of the need to simultaneously exclude the hypogastric arteries. Dynamic fluid balance phenomena provoked by closure of the AVF are described. The patient had a benign postoperative course with normalization of the severe hemodynamic changes presented prior to the intervention and resolution of respiratory symptoms attributed to pulmonary arterial hypertension.
动静脉瘘（AVF）是自发性动脉瘤破裂进入相邻静脉系统的一种罕见后遗症。我们描述了一例74岁患者的病例，该患者接受了由髂总动脉（CIA）动脉瘤破裂导致的右髂动静脉瘘以及左髂总动脉远端动脉瘤的血管内治疗。由于需要同时排除腹下动脉，手术保留了腰动脉和肠系膜下动脉。描述了动静脉瘘闭合引发的动态液体平衡现象。患者术后病程良好，干预前出现的严重血流动力学变化恢复正常，肺动脉高压所致的呼吸症状也得到缓解。
