Persistent Left Superior Vena Cava Identified during Cadaver Dissection: A Case Report

Persistent left superior vena cava (SVC), resulting from the persistence of the left anterior cardinal vein, is most frequently observed as a component of a double SVC system. Since this venous anomaly is insignificant in hemodynamics, it is often discovered incidentally during the placement of intravenous catheters or electrode leads. Recognizing such anomalies is clinically significant, because it can help avoid diagnostic errors, suggest the potential presence of associated abnormalities, and aid in the planning of vascular interventions or surgical procedures. In this report, we present a case of persistent left SVC identified during a regional anatomy course, which will significantly enhance the understanding of this congenital variation.
