Central Cannulation Through a Standard Left Thoracotomy for Surgery on the Descending Thoracic Aorta

Surgery on the descending thoracic aorta is often performed with hypothermic cardiopulmonary bypass established via the femoral vessels. This, however, produces retrograde flow, which may potentially dislodge atheromatous debris from a diseased descending aorta or results in malperfusion due to cannulation of the false lumen in patients with descending aortic dissection. In view of this, we have described a technique of central cannulation of the ascending aorta and main pulmonary artery, established via a standard left thoracotomy, providing antegrade flow and limiting the cerebral ischemic time.
