[One-stage bilateral STA-MCA anastomosis in multiple occlusive cerebrovascular disease].
Out of 12 cases of bilateral stenosis of the internal carotid (IC) system underwent unilateral STA-MCA anastomosis on the symptomatic side, no ischemic signs recurred in 8 cases, while, in the remaining 4, symptoms appeared postoperatively, requiring the anastomosis of the contralateral side. Preoperative findings of CT scan, CAG and r-CBF were reviewed and compared. It has, consequently, become evident that, in the latter 4 cases, angiography showed stenotic lesion of over 50% of the ICA lumen, between the mastoid-mandibular line (MML) and the circle of Willis, on the initially asymptomatic side. Furthermore, in the same 4 cases, multiple thrombotic foci were more liable to be demonstrated on the CT scans and r-CBF was lowered in both hemispheres without significant difference in laterality. In additional 7 cases presenting such characteristics as stated above, one-stage bilateral STA-MCA anastomosis was carried out with a successful result.
