ANALYSIS OF EFFECT AND COMPLICATION ON SURGICAL TREATMENT OF CAROTID BODY TUMORS IN 46 CASES

摘要

Objective. To describe the effects of surgical treatment and complications in 46 patients with carotid body tumor (CBT). Method. Retrospective study on surgical treatment and complications was carried out in 46 cases of CBT which were surgically treated with different kind of procedures. Result. All procedures performed successfully except that the CBT was not excised in 4 cases. No operative mortality was observed. There were 2 postoperative hemiplegia, 4 hypoglossal nerve impairment, 2 glossopharyngeal nerve impairment, 1 vagus nerve impairment, and 1 accessory nerve impairment. One patient presented postoperative cranial nerve impairment in glossopharyngeal, vagus and hypoglossal nerves. Two patients developed local recurrence during the long- term follow- up. Conclusion. Complete surgical excision was possible in each patient if the diagnosis had been correctly made through selective preoperative angiography, vessel ultrasound Doppler and other examinations. Reasonable surgical procedure and Matas training were necessary to the successful surgical treatment and thus decrease the complicative incidence rate of carotid chemodectomas.
