We describe a case of unsuspected infrahepatic interruption of the inferior vena cava with hemiazygos continuation in a 67-year-old man presenting with chest pain and evidence of mitral regurgitation. He had no persistent superior vena cava, with the hemiazygos draining directly into the right superior vena cava. Polysplenia and severe mitral prolapse were also present: the latter may represent more than an incidental finding in this condition. This malformation may deserve consideration in adults undergoing femoral right heart catheterization. Chest radiographic studies are the basic clue to the diagnosis.
我们描述了一例67岁男性患者，其下腔静脉在肝下未被怀疑的中断并伴有半奇静脉延续，该患者表现为胸痛和二尖瓣反流的证据。他没有永存上腔静脉，半奇静脉直接汇入右上腔静脉。同时还存在多脾和严重二尖瓣脱垂：在这种情况下，后者可能不仅仅是一个偶然发现。对于接受股静脉右心导管检查的成年人，这种畸形可能值得考虑。胸部X线检查是诊断的基本线索。
