Abstract:
Persistent left superior vena cava can present as a benign anatomic finding or as a pathologic entity, causing significant hemodynamic manifestations. Its presence can also promote modifications in the surgical techniques used for treatment of other cardiac pathologies. When persistent left superior vena cava constitutes a pathologic entity that needs to be surgically addressed, this can be approached either by intracardiac or extracardiac procedures. Extracardiac procedures appear simpler and reproducible. A previously reported technique for extracardiac approach of left superior vena cava using an enlarged left superior vena cava-right atrial appendage anatomosis is reviewed.

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.
