Aortocaval fistulas are most commonly the result of spontaneous rupture or erosion of an abdominal aortic aneurysm into the inferior vena cava (80-90%). The remaining 10-20% of aortocaval fistulas are usually the result of penetrating or iatrogenic trauma from gunshot or stab wounds. We report the case of a 19-year-old male, status post multiple gunshot wounds. To our knowledge, this is the first case report of bullet embolization to the right ventricle from a traumatic aortocaval fistula. We discuss pertinent imaging findings and management of both aortocaval fistulas and bullet emboli.
主动脉腔静脉瘘最常见的原因是腹主动脉瘤自发性破裂或侵蚀进入下腔静脉（80%-90%）。其余10%-20%的主动脉腔静脉瘘通常是由枪伤或刺伤等穿透性或医源性创伤导致的。我们报告了一例19岁男性，有多处枪伤史。据我们所知，这是首例因创伤性主动脉腔静脉瘘导致子弹栓塞至右心室的病例报告。我们讨论了主动脉腔静脉瘘和子弹栓塞的相关影像学表现及处理方法。
