[A case of carotid body tumor. A review of 84 cases in Japanese literature].

We encountered one case of carotid body tumor. The patient was a 63-year-old man. The tumor was 5 cm X 6 cm in size, and it was strongly adhered to the carotid artery. Therefore, the tumor was removed with combined resection of the adherent lesion of the carotid artery. During the operation, we used a temporary external bypass method to prevent brain damage. The resected part of the carotid artery was reconstructed with saphenous vein graft. Angiogram one year after operation showed good patency of the graft. In Japanese literature, this is the second report of carotid body tumor removed by temporary bypass and the first report of use of a external bypass tube.
