An unusual case is presented, in which mitral stenosis was accompanied by a persistent left superior vena cava communicating through a venous channel with the left pulmonary veins. The pulmonary veins were normally connected to the left atrium, but, due to elevation of the left atrial pressure from the mitral valve lesion, pulmonary venous blood was directed up the left superior vena cava to reach the right atrium. Although from an anatomical viewpoint this did not constitute true anomalous pulmonary venous drainage, the condition behaved as such haemodynamically. It was only at operation that the diagnosis was firmly established, but after mitral valvotomy the abnormal venous channel was obliterated by simple ligation without incident.
本文报告了一例罕见病例，该病例中二尖瓣狭窄伴有持续存在的左上腔静脉，通过静脉通道与左肺静脉相通。肺静脉正常连接至左心房，但由于二尖瓣病变导致左心房压力升高，肺静脉血经左上腔静脉向上流入右心房。尽管从解剖学角度来看，这并不构成真正的肺静脉异位引流，但在血流动力学上却表现如此。仅在手术时才明确诊断，然而在二尖瓣切开术后，通过简单结扎异常静脉通道，未发生任何意外情况，通道即被闭塞。
