Abstract:
A persistent sciatic artery is a rare congenital variant of blood flow to the lower extremity and is not classically associated with venous malformations. In this case, we describe aberrant central venous anatomy anterior to the arterial system that was encountered during exposure of the distal aorta during an elective aortobifemoral bypass, fortunately without significant bleeding, which could be catastrophic. Under-reporting of aberrant central venous anatomy with a congenital sciatic artery can be due to infrequent venous-phase imaging and limited open vascular interventions in the pelvis.

Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
