title: Superficial temporal-middle cerebral artery anastomosis: effects on vascular, neurologic, and neuropsychological functions.
abstract: In 44 patients, we studied the effects of superficial temporal-middle cerebral artery anastomosis on cerebral blood flow (CBF), neurologic examination, and cognitive functions. At 3 months, there was significant improvement in all variables. At 9 months, CBF was no longer significantly greater, but neurologic examination and cognitive functions had further improved. Patients with TIA had significant postoperative decreases in TIA frequency and did not progress to stroke, but had no significant changes in any variable. In stroke patients, we could not separate the effects of surgery from the natural evolution of changes in CBF and examination after stroke. None of the preoperative measurements predicted postoperative clinical improvement.
