Persistent left-sided superior vena cava (PLSVC) is a central venous anomaly in up to 0.5% of the population. It is usually asymptomatic due to drainage into the right atrium via the coronary sinus. This case report describes placement of a dialysis catheter in a 55-year-old patient with PLSVC and subsequent complications following the uncertainty of the placement. In 10%, PLSVC drains to the left atrium inducing risk of left-to-right shunt and fatal paradoxical emboli in case of catheterisation. Hence, clarification of the central venous haemodynamics by relevant imaging modalities is advised, if suspicion arises.
持续性左侧上腔静脉(PLSVC)是一种中心静脉异常,在人群中的发生率高达0.5%。由于通过冠状窦引流至右心房,它通常无症状。本病例报告描述了一名55岁PLSVC患者透析导管的置入以及置入位置不确定后的并发症。在10%的病例中,PLSVC引流至左心房,导致左向右分流风险,在进行导管插入术时会出现致命的反常栓塞。因此,如果出现怀疑,建议通过相关影像学检查明确中心静脉血流动力学情况。
