Distal carotid perfusion in combined carotid endarterectomy and OP-CABG.

An alternative method of maintaining carotid perfusion during combined carotid endarterectomy and off-pump coronary artery bypass grafting involves insertion of a cannula in the ascending aorta after a median sternotomy. This cannula is connected to a perfusion cannula, the distal end of which is inserted into the carotid artery beyond the carotid arteriotomy. This technique of aortico-carotid shunting and carotid perfusion was utilized in nine patients who underwent successful combined carotid endarterectomy and off-pump coronary artery bypass grafting.
