Abstract：
Arteriovenous malformations are a vascular anomaly most often found in the central nervous system; however, they can present ubiquitously in any organs or tissues. We present the case of a 55-year-old man who developed a tender, reducible inguinal bulge and underwent laparoscopic transabdominal preperitoneal inguinal hernia repair under the clinical diagnosis of an inguinal hernia. Intraoperative observation revealed no hernia sac, but a poorly defined spermatic cord mass, appearing to be responsible for the patient\'s symptoms, was found and removed. The pathology of the mass was consistent with the diagnosis of an arteriovenous malformation of the spermatic cord. Surgeons should keep in mind the small possibility of arteriovenous malformations in patients with clinical presentation of an inguinal hernia, as they may cause massive bleeding during and after the operation unless handled appropriately.
摘要：
动静脉畸形是最常见于中枢神经系统的血管异常；然而，它们可以在任何器官或组织中普遍存在。我们介绍了一个55岁的男子的情况，在腹股沟疝的临床诊断下，可减少腹股沟膨出并接受腹腔镜经腹腹膜前腹股沟疝修补术。术中观察无疝囊,但是精索质量不明确，似乎对病人的症状负责，被发现并删除。肿块的病理与精索动静脉畸形的诊断一致。外科医生应记住，在有腹股沟疝临床表现的患者中，动静脉畸形的可能性很小。除非处理得当，否则在手术期间和之后可能会导致大量出血。
