CT findings of a clinically occult abdominal aorto-caval fistula secondary to atherosclerotic abdominal aortic aneurysm are presented. A review of 20 CT's demonstrating nonruptured abdominal aortic aneurysm was conducted. This review, in conjunction with the case presented, suggests that extensive caval effacement, with loss of the aorto-caval fat plane is an uncommon finding, and may indicate the presence of a thrombotically occluded aorto-caval fistula.
本文报道了一例由动脉粥样硬化性腹主动脉瘤继发的临床隐匿性腹主动脉-腔静脉瘘的CT表现。对20例显示未破裂腹主动脉瘤的CT进行了回顾性分析。结合所报道的病例,这种回顾提示,腔静脉广泛受压、腹主动脉-腔静脉脂肪平面消失是一种不常见的表现,可能提示存在血栓闭塞性腹主动脉-腔静脉瘘。
