To report on the double superior vena cava occurring with anomalous azygous vein and abnormal termination of the cardiac veins, which has not been reported before in one individual.
Examination of the heart revealed the presence of both the right and left superior vena cava. The right superior vena cava terminated into the right atrium and received the right root of the azygous vein, and the left superior vena cava received the left root of the azygous vein before entering the dilated coronary sinus. The azygous vein ascended in the right chest, and at the level of the third thoracic vertebra, it divided into the right and left roots, which joined the respective superior vena cava. Observation of the left lung revealed the presence of both the oblique and horizontal fissures that demarcated the upper, middle, and lower lobes. Dissection of the neck revealed abnormal connection of the superficial veins. The left external and anterior jugular veins opened at the confluence of veins that was drained by the venous arch that passed to the right side of the neck to open into the right external jugular vein.
The coexistence of double superior vena cava with azygous and superficial jugular venous anomalies is considered to be incidental finding. However, continued documentation of such anomalies is clinically important, and it remains to be important in medical science.
报告一例同时存在双上腔静脉、奇静脉异常及心静脉异常终止的病例，此前未见单个个体同时出现这些情况的报道。
心脏检查发现存在右、左双上腔静脉。右上腔静脉汇入右心房并收纳奇静脉右根，左上腔静脉在汇入扩张的冠状窦之前收纳奇静脉左根。奇静脉在右胸上升，在第三胸椎水平分为右、左根，分别汇入各自的上腔静脉。左肺观察发现有斜裂和水平裂，将上、中、下叶分隔开。颈部解剖发现浅表静脉存在异常连接。左颈外静脉和颈前静脉开口于静脉汇合处，该汇合处由静脉弓引流，静脉弓通向颈部右侧，开口于右颈外静脉。
双上腔静脉与奇静脉及颈浅静脉异常并存被认为是偶然发现。然而，持续记录此类异常在临床上具有重要意义，在医学领域也依然重要。
