Abstract:

Azygos vein aneurysm is very rare and most cases are detected incidentally. We report a safe resection of azygos vein aneurysm by video-assisted thoracoscopic surgery (VATS) under preoperative evaluation of thrombus by multidetector computed tomography (MDCT). A 60-year old woman presented to our department due to a mediastinal mass revealed by enhanced CT. A dynamic enhanced-CT scan showed a dilated azygos vein with great enhancement in the early phase. Under the diagnosis of azygos vein aneurysm, we analysed the aneurysm by MDCT and confirmed that there was no thrombus within the aneurysm. The resection of the aneurysm by VATS was performed safely. She was discharged 4 days after surgery.

Veins of Thorax

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
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.
