Stroke is the second or the third leading cause of death and the leading producer of disability among adults in Lithuania and Western countries. Surgery is very important to treatment and prevention of ischemic cerebrovascular disease, but the selection of patients for it must be based on meticulous evaluation of surgery risk and factors influencing follow-ups. The aim of this study was to evaluate the selection criteria for cerebral revascularisation in patients with ischemic cerebrovascular diseases and factors affecting postoperative follow-ups. The innovativeness and originality of this study is the complex evaluation of neurological, neuroradiological, neurophysiological factors in patients with ischemic cerebrovascular disease before and after cerebral revascularisation. The evaluation of the influence of cerebral revascularisation to the neurological status of the patients, the possibilities of cerebral revascularisation for patients with Moyamoya disease, the factors affecting the neurological status of patients after cerebral revascularisation, the postoperative complications, death causes of patients after cerebral revascularisation and the surviving after cerebral revascularisation was done.
