Persistent left superior vena cava with an absent right superior vena cava in a 72-year-old male with multivessel coronary artery disease

Abstract

Congenital anomalies of systemic veins are usually asymptomatic and found incidentally during ultrasonography, computed tomography (CT) or magnetic resonance examinations performed for other clinical indications. Persistent left superior vena cava (PLSVC) with absent right superior vena cava (RSVC) is the congenital aberration in the thoracic venous system which occurs in only 0.09% to 0.13% of patients who have congenital heart defects. In this paper, we present the extremely rare case of a 72-year-old male with PLSVC associated with an absence of RSVC, referred for coronary CT angiography. Multidetector CT angiography is a powerful tool for the detection of venous anomalies, which is essential before invasive procedures such as the implantation of pacemakers.
