Beyond the Right Superior Vena Cava: CT Depiction of Persistent Left Superior Vena Cava Variants
Abstract: Background: Persistent left superior vena cava (PLSVC) is rare congenital thoracic venous anomaly, resulting from failure of involution of the inferior segment of left anterior cardinal vein during embryogenesis. Although frequently asymptomatic, PLSVC may have important clinical implications during central venous catheterization, cardiac device implantation, and cardiothoracic surgery. Cases: We present here four cases of PLSVC who presented with transfusion-associated circulatory overload (TACO), central venous catheter extending through anomalous vessel along the left heart border and isolated PLSVC with absent right superior vena cava. Conclusion: PLSVC encompasses a broad spectrum of anatomical variants with variable clinical significance. Recognition of these anomalies on CT is essential for accurate interpretation of thoracic imaging, safe central venous access, and pre-procedural planning.
