Giant mastoid emissary vein: source of profuse bleeding during mastoid surgery
Abstract:
The emissary veins are residual connections between intra-cerebral veins and their extra-cranial drainage. Mastoid emissary vein is a rare but definite entity which if not diagnosed preoperatively could be a cause of severe hemorrhage at the time of surgery which may prove to be life threatening. These veins may vary in size from that of a mere thread to that of a wax match or 1/8th-3/8th of an inch. We report one such case of a giant mastoid emissary vein which was opened while operating on mastoid and caused profuse bleeding which could only be controlled by surgical pack.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
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.
