Abstract

Introduction: Cerebral angiosmasm is the main factor for poor prognosis while aneurism intracranial hemorrhages. Objective: to define the cerebral angiospasm dynamics and optimal term of surgical treatment in patients with aneurism intracranial hemorrhages. Materials and methods of research: 76 patients with subarachnoid aneurism hemorrhages, complicated by cerebral angiospasm development are included in the research. To define transcranial Doppler sonography indices causation from the day of hemorrhage methods of correlation and regress analysis were used. Results of research: Renewed regression demonstrates the growth of central tendency for systolic speed of blood stream up to the 10th day of clinical course with its further fall off. Dependence of diastolic blood velocity and average blood flow rate in the medial cerebral artery on the day was described by linear splineregression with two junctions, i. e. the 9th and the 10th day. From the disease onset till the 9th day diastolic blood flow speed and average blood flow rate were stable; the jump of values was observed on the 10th day. Starting from the 10th day there was regress and decline of intracraneal pressure. Similar changes took place in the а. cerebri anterior, а. cerebri posterior and arteria carotis interna. In patients with angiospasm the 9–10th day after subarachnoid aneurism hemorrhage is the term when the highest blood linear velocity rate and peripheral impendence in intracranial vessels figures are observed. Conclusions: Optimal terms for intracranial operational invasion in patients with angiospasm is the 10th day after hemorrhage as the date of the angiospasm regression beginning.
