Internal
Thoracic Artery in the Treatment of Coronary Artery Disease
In patients with occlusive coronary disease caused by
atherosclerosis, the diseased arterial segment can be bypassed by inserting a
graft. The graft most commonly used is the great saphenous vein of the leg. In
some patients, the myocardium can be revascularized by surgically mobilizing one
of the internal thoracic arteries and joining its distal cut end to a coronary
artery.
Lymph Drainage of the Thoracic Wall
The lymph drainage of the skin of the anterior chest wall passes to the anterior axillary lymph nodes; that from the posterior chest wall passes to the posterior axillary nodes. The lymph drainage of the intercostal spaces passes forward to the internal thoracic nodes, situated along the internal thoracic artery, and posteriorly to the posterior intercostal nodes and the para-aortic nodes in the posterior mediastinum.
