Carotid Interposition Grafting
Carotid interposition grafting (CIG) is an uncommon operation as compared to carotid endarterectomy (CEA). The exposure is similar to CEA for high plaque. In some patients, distal control of the ICA may necessitate balloon occlusion. Interposition graft material can be a tapered PTFE graft, greater saphenous vein graft, or superficial femoral artery conduit in patients with head and neck malignancy invading the carotid artery. Distal anastomosis of the graft to the divided ICA is performed first followed by proximal anastomosis of the divided CCA to the graft. The external carotid artery is usually ligated.
