[Prognostication of ischemic complications of cerebral vasospasm in surgical treatment of intracranial aneurysm in acute period of its rupture].

With objective to create a model of prognostication of ischemic complications, occurred due to cerebral vasospasm (CVS), the informativeness of some clinic-instrumental indices was investigated in 350 patients in an acute period of intracranial arterial aneurysm rupture, using mathematical processing of the data. The terms from the disease beginning (3 - 14th day), severe state of patient while stay in hospital, localization of rupture in internal carotid artery, conduction of operation in terms up to 11 days after the rupture occurrence, presence of intraoperative complications, pronounced spasm of 3 and more segments of arteries preoperatively in accordance to angiography data, the pronounced and critical spasm postoperatively in accordance to ultrasonography data have had evolved as a prognostically significant causes in the CVS ischemic complications occurrence. The proposed model of prognostication of a deferred ischemic complications of CVS have had sensitivity 85%, specificity 75%, what have oermitted to use it in clinical practice.
