A persistent left superior vena cava (PLSVC) is the most common variation of the thoracic venous system,[1][1] is prevalent in 0.3% of the population,[1] and an embryologic reminant that results from a failure to involute.
In PLSVC, the left brachiocephalic vein does not develop fully and the left upper limb and head & neck drain into the right atrium via the coronary sinus. The variation, in insolation, is considered benign, but is very frequently associated with cardiac abnormalities (e.g. ventricular septal defect, atrioventricular septal defect) that have a significant mortality and morbidity.[1] It is more frequent in patients with congenital heart defects.[1]

 Image 1 - Duplication of inferior vena cava. This is a not uncommon variation. The left sided IVC (black arrow) most commonly ends in the normal left renal vein. Image 2 - Duplication of superior vena cava. This is a rare variation of the SVC. The left sided SVC (white arrow) is draining into the left atrium, thereby bypassing the pulmonary circulation. The right SVC is normal. [1] [1] (Image courtesy of Dr Abhijit Datir) |
