Elective carotid artery resection for advanced squamous cell carcinoma of the neck.

The authors performed a retrospective review of their 10-year experience of carotid artery resection without revascularization for advanced squamous cell carcinoma of the neck. From 1982 to 1991, seven patients underwent elective carotid artery resection without reconstruction at the University of Colorado Health Sciences Center in Denver. A vascular clamp with gradual carotid occlusion was placed preoperatively on four patients and awake temporary balloon occlusion of the carotid was used on three patients. The primary lesions were three laryngeal carcinomas, two oral cavity carcinomas, and two hypopharyngeal carcinomas. All seven resected specimens showed invasion of the carotid fascia on pathological exam, while five specimens exhibited actual destruction of the arterial wall. Cerebrovascular accidents occurred in two patients (one immediate and one delayed), and the perioperative mortality was 29% (one cerebrovascular accident and one gastrointestinal bleed). The five remaining patients died of locoregional recurrence or metastatic disease within 1 year after their carotid artery resection. Resection of the common or internal carotid artery without reconstruction has a significant morbidity and mortality. This operation did not improve the long-term survival in our limited series of patients who presented with histologically proven invasion of the carotid artery.
