CAROTID-ARTERY REPLACEMENT IN CONJUNCTION WITH RESECTION OF SQUAMOUS-CELL CARCINOMA OF THE NECK - PRELIMINARY-RESULTS

Squamous cell carcinoma can invade the carotid artery. The treatment options then include irradiation, "palliative peeling" of tumor from the artery, and carotid resection with ligation or in-line grafting. Twelve patients with invasion of the carotid artery by cancer had en bloc resection of the artery and tumor. Reconstruction after in-line carotid artery grafting with autogenous vein was completed with a myocutaneous flap. No neurologic events occurred perioperatively or during the follow-up period of 3 to 50 months. Computed tomography and arteriography were unreliable in predicting tumor involvement of the carotid artery. Three patients died during the study-two of unrelated causes, and one of metastases. None of the patients showed evidence of local recurrence from 3 to 50 months. In two of four wound infections the carotid artery graft was exposed. This was successfully treated by a myocutaneous flap. The mean survival for the group was 18 months. Resection and in-line bypass grafting of the carotid artery invaded by cancer can safely be performed in irradiated and potentially infected fields.
