Abstract:
We analyzed the routes of draining veins in 7 cases of intralobar pulmonary sequestration (ILS) and 6 cases of bronchial atresia (BA) by multidetector CT and on 3D reconstructed images. In 2 cases of ILS with systemic venous drainage and 4 of 5 cases with pulmonary venous drainage, the primary veins penetrated the abnormal lungs. In another case, the main vein bypassed the border of the lung, but a small number of branches joined from the normal lung. In all cases of BA, draining veins distributed outside the abnormal lung. The finding that ILS has its own draining veins supports the theory of its congenital origin from an accessory lung bud.

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.
