title: Emergency cannulation for proximal perfusion in descending thoracic aorta procedures.
abstract: Acute cardiac failure during descending thoracic aorta operations, although rare, may have catastrophic consequences. Under these circumstances, the use of partial veno arterial bypass is advantageous, allowing an assisted perfusion of both proximal and distal circulation districts. Traditionally, the ascending aorta or the aortic arch are the preferred sites of cannulation for proximal arterial reinfusion, but some limitations, such as extensive calcifications or extreme fragility of these segments, may hamper or at least delay this action. Herein, we describe a simple technique for rapid cannulation of proximal aorta in emergency circumstances.
