Clinical experiences with STA-MCA anastomosis in 54 cases
Since 1970 superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis has been performed in 54 patients. These patients were randomized into six categories (Table 25.1). On the basis of this experience certain observations are pertinent. We have not noted a significant difference in the operative results when comparing patients with internal carotid lesions and patients with middle cerebral artery lesions. By far the best results were obtained when STA-MCA anastomosis was utilized as the treatment for patients suffering transient ischemic attacks with evidence of occlusive organic vascular lesions. We feel that patients with severe fixed neurologic deficits are not useful candidates for the procedure. The relationship of age to postoperative results is given in Table 25.2. We have not been able to relate the factor of age to a specific postoperative result. The duration from the onset of the first vascular insult to the time of surgery does not appear to be an important factor in postoperative prognosis (Table 25.3). The clinical syndrome is clearly the most important factor in deciding whether such operation may be useful.
