Aortocaval fistulae are rare entities with a variety of etiologies and are very often associated with significant morbidity and mortality. It is believed that increased tension in the walls of large aneurysms can cause an inflammatory reaction resulting in adhesion to the adjacent vein and culminating in erosion of the adherent layers and fistula formation. Conventional surgical treatment has high mortality rates. Paradoxical pulmonary embolism and endoleaks are the most concerning complications linked with endovascular treatment. Using a vascular occluder in combination with a bifurcated endograft is a good option for the treatment of an abdominal aortic aneurysm with aortocaval fistula.
主动脉腔静脉瘘是一种病因多样的罕见病症，常伴有严重的发病率和死亡率。据信，大型动脉瘤壁张力增加会引发炎症反应，导致与相邻静脉粘连，最终导致粘连层侵蚀和瘘管形成。传统手术治疗死亡率高。反常性肺栓塞和内漏是与血管内治疗相关的最令人担忧的并发症。使用血管封堵器结合分叉型覆膜支架是治疗伴有主动脉腔静脉瘘的腹主动脉瘤的一个不错选择。
