aortic cannulation
Insertion of a cannula into the ascending aorta to return oxygenated blood from the heart-lung machine.
Full Definition
Aortic cannulation is a critical step in establishing cardiopulmonary bypass, involving the placement of a large-bore cannula into the ascending aorta to facilitate the return of oxygenated blood from the cardiopulmonary bypass circuit to the systemic circulation. The cannula is typically inserted through a purse-string suture in the ascending aorta, allowing for controlled perfusion of the body while the heart is stopped. Proper placement and secure fixation are essential to prevent air embolism, bleeding, or inadequate perfusion.
Usage
Usage note: Specify location (ascending aorta, arch, femoral) when describing cannulation technique.
