Three cases operated on by ligation of the common carotid artery and 4 cases by reconstruction for radical neck dissection were reported. Four cases were examined with 133Xe cerebral blood flow scintigraphy. The first case, operated on by ligation, was examined on the 18 th postoperative month. Scintigraphy showed normal regional cerebral blood flow (rCBF). The second case, operated on by reconstruction with Gore-Tex, showed normal rCBF preoperatively and on the 15 th postoperative day, and showed abnormal rCBF in left frontal lobe on the 35 th postoperative day which was on the 5 th day after an occurrence of a cerebral infarction. The third case in which hemorrhage occurred a month after reconstruction of the saphenous vein, and the last case operated on by ligation showed normal rCBF preoperatively. Postoperatively, the third case on the 28 th day and the last case on the 10 th day had low rCBF in temporal lobe. These findings were not detected by X-ray CT performed at nearly the same time. The last case was examined again on the 3 rd postoperative month and showed normal rCBF.
