Persistent left superior vena cava occurs in 2-4% of all congenital cardiac defects. The diagnosis is often missed if the lesion is not accurately looked for. Drainage to the coronary sinus is well tolerated, whereas drainage to the left atrium produces right to left shunt and may be associated with brain abscesses and/or embolization secondary to intravenous therapy administered through the left arm. This paper describes for the first time the diagnosis of persistent left superior vena cava by transesophageal contrast echocardiography. Echocardiography is the method of choice in the diagnosis of persistent left superior vena cava, because it can be used at the patient's bedside and allows easy detection of the drainage site.
永存左上腔静脉在所有先天性心脏缺陷中占2% - 4%。如果未准确查找该病变，诊断常常会被漏诊。引流至冠状窦通常耐受性良好，而引流至左心房则会产生右向左分流，并且可能与因通过左臂进行静脉治疗继发的脑脓肿和/或栓塞有关。本文首次描述了经食管对比超声心动图诊断永存左上腔静脉的方法。超声心动图是诊断永存左上腔静脉的首选方法，因为它可在患者床边使用，且能轻松检测到引流部位。
