Persistent Left Superior Vena Cava Incidentally Recognized Postoperatively After Venous Port Placement

Abstract

Persistent left superior vena cava is the most common congenital venous anomaly of the thoracic venous system, occurring in 0.3% to 0.5% of individuals in the general population. It may remain asymptomatic throughout life and be incidentally found in healthy individuals undergoing vascular procedures such as venous access device placements and endovascular cardiac interventions.Here we present a case of persistent left superior vena cava incidentally realized during chemoport insertion in a patient with breast cancer.

Intraoperative identification of persistent left superior vena cava with intracavitary electrocardiogram during venous port insertion: A report of eight cases

“…There are numerous reports on central catheters inserted into this vein, including central inserted central catheters (CICCs), 8,12 dialysis catheters, [13][14][15] peripheral inserted central catheters (PICCs), 16,17 and ports. 6,18 The anatomical aspect of this anomaly is described in detail elsewhere 1,19 and is not the main topic of this report. In this report, we mainly discuss the intraoperative IC-ECG findings in PLSVC and its related clinical aspects.…”
