Abstract:
The authors report a rare case of hemangioendothelioma of the right innominate vein complicated by superior vena cava syndrome. Considering development of enlarged venous collaterals, we performed circular resection of superior vena cava together with the right and left innominate veins without replacement. There were no postoperative complications. The use of vascular prosthesis in patients with long-standing superior vena cava compression and enlarged collaterals is associated with high risk of thrombosis and subsequent pulmonary embolism. Safe circular resection of superior vena cava without replacement is possible after intraoperative test clamping.

Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

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.
