Abstract
Since carotid body tumor generally arises in the furcation of internal and external carotid arteries, the tumor often involves the internal and external arteries which causes not only a massive hemorrhage at the excision but also an inevitable simultaneous excision of the arteries as well as the tumor in some cases.
We have succeeded in safe surgery for carotid body tumor with hemorrhage by preoperative matas test using balloon catheter to confirm a cross circulation from the another paired internal carotid artery and further use of balloon catheter during surgery.
This method appears to be very valuable in prophylactic acid for postoperative complications when the another side of carotid artery is probably ligatured and/or excised.
