Persistent left superior vena cava is an anomaly of the systemic venous return occurring in 0.5% of the general population. We report the case of a patient with an incidental diagnosis made during a dyspnea while he had chronic pulmonary disease. The diagnosis was suspected by the presence of a markedly dilated coronary sinus and confirmed by a simple contrast injection into the left antecubital vein. Transesophageal echocardiography and magnetic resonance imaging confirmed the existence of 2 superior vena cava with the left superior vena cava draining into the coronary sinus. This congenital anomaly is of minimal hemodynamic significance when isolated. The diagnosis can be useful for placement of central catheters from left superior approach.
永存左上腔静脉是一种体静脉回流异常，在普通人群中的发生率为0.5%。我们报告了一例患者，在其患有慢性肺部疾病出现呼吸困难时偶然诊断出该疾病。通过显著扩张的冠状窦怀疑该诊断，并通过向左肘前静脉简单注射造影剂得以证实。经食管超声心动图和磁共振成像证实存在两条上腔静脉，左上腔静脉汇入冠状窦。这种先天性异常单独存在时对血流动力学影响极小。该诊断对于经左上途径放置中心静脉导管可能有用。
