Vertebral arteriovenous fistula is an abnormal communication between the vertebral artery and adjacent venous structures. The most common cause of vertebral arteriovenous fistula is trauma, however, spontaneous occurrence is also known. We report a case of traumatic pseudoaneurysm with associated vertebral arteriovenous fistula which occurred following stab injury to the left vertebral artery. The diagnosis was suspected clinically and on CT angiography. Digital subtraction angiography confirmed the diagnosis, and a covered stent was placed in the left vertebral artery at the site of the injury following which there was complete closure of the pseudoaneurysm and fistula and anterograde flow was restored in the vertebral artery.
椎动脉动静脉瘘是椎动脉与相邻静脉结构之间的异常交通。椎动脉动静脉瘘最常见的病因是创伤，不过，也有自发发生的情况。我们报告一例因左椎动脉刺伤后出现的伴有椎动脉动静脉瘘的创伤性假性动脉瘤病例。临床及CT血管造影检查怀疑有该诊断。数字减影血管造影术确诊了该诊断，并在损伤部位的左椎动脉置入了覆膜支架，之后假性动脉瘤和瘘完全闭合，椎动脉恢复了顺行血流。
