Changing the strategy and outcomes of cerebral aneurysms management

The paper analyzes the outcomes of treatment of 538 patients with arterial aneurysms. The patients were divided into two groups according to time intervals. The first group included 275 people, of whom 207 patients (75.3%) were exposed to microsurgical clipping and 68 (24.7%) underwent endovascular treatment. The second group comprised 263 patients. Mortality in the endovascular subgroup of the second group was 1.6%. Preconditioning technology in microsurgery of large and giant aneurysms proved to be a useful procedure for the protection of ischemic brain lesions. The strategy of using endovascular treatment demonstrates a decline in surgical mortality.
