Preoperative volume and degree of ischemic involvement of the brain shown by single-photon emission computer-aided tomoscintigraphy (SECT) and the time course of neurologic status following reconstructive surgery on the carotid arteries were studied in 20 patients with acute disorders of cerebral circulation. The volume of hypoperfused cerebral tissue (Vhypoperf.) and volumic index of cerebral tissue hypoperfusion (Vs) were calculated from the data of tomoscintigraphy of the brain. The Vs and Vs/Vhypoperf. values in patients with acute disorders of cerebral circulation were reliably lower in subjects with a favourable postoperative time course of the neurological status. Hence, the minimal value of the volumic index of cerebral tissue hypoperfusion and low Vs/Vhypoperf. ratio may predict favourable functional neurological rehabilitation under conditions of recreated bloodstream with a high probability.
