Abstract:
Papillary thyroid carcinoma with massive invasion into the great veins of the neck and mediastinum has rarely been reported and is thought to have a poor prognosis. Here we report successful management of a case of papillary thyroid carcinoma with extensive invasion into the left internal jugular vein, left brachiocephalic vein, and superior vena cava, followed by reconstruction of the superior vena cava using an artificial graft. The operation was conducted to prevent sudden death due to complete obstruction of venous flow, improve the patient's quality of life, and prolong survival. The patient has survived for more than two years after surgery, with good general condition.

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.
