ABSTRACT
We retrospectively analysed the administration of anaesthesia for carotid body tumor resection in Siriraj Hospital during 1985-1991. The tumors were excised from seven patients under general hypotensive anaesthesia. Such slow-growing large tumors frequently encircle the internal and external carotid arteries, which increases the risk of massive blood loss and damage to major cranial nerves. Thus, carotid arteriography for diagnosis and demonstration of collateral circulation and cardiovascular monitoring during resection was indispensable. All tumors were completive death. Following surgery, one patient developed transient weakness of the upper extremity which lasted one week. Cranial nerve palsy (CN IX, X) occurred in one patient who recovered in three months.
