Treatment of cerebral aneurysms in the acute stage of subarachnoid hemorrhage (SRH) especially on the background of cerebral vasospasm continues to be a difficult task. Objective — assessment of dynamics of the surgical treatment results of patients with cerebral aneurysms in acute period of SRH. Material and methods. A comparative analysis of the results of patients’ surgical treatment in NMRCN Burdenko about aneurysm in 1—21 days after hemorrhage was made. The following periods were selected: 2006—2014 (343 patients) and 2015—2018 (356 patients). Most patients had microsurgical operations in both periods. The tactics of choosing the surgery time was the main difference between the periods: particularly in 2015—2018 period the surgery was not postponed at patients with severe. Results. Analysing the post surgical mortality, it was found that since 2006 there is a consistent trend towards a decrease in the number of patients who died after surgery. When calculating the average post surgical mortality for the studied periods this trend is confirmed — number of lethal cases in 2015—2018 reliably decreased when comparing with 2006—2014 — from 6.8 till 3.2%; p=0.03. At the same time, the number of patients with outcome of vegetative status (from 0.3 till 5%). Conclusion. The tactics of surgical treatment of patients with cerebral aneurysms in the acute period of SRH regardless of severity of patient’s condition and time of hemorrhage did not lead to worse treatment. In contrast, post surgical mortality rates show a consistent decline. We associate this fact with a number of changes that have occurred in the management and treatment of patients. In particular, we have high hopes for developing new approaches to the treatment of vasospasm, which remains the leading cause of lethal cases. More definite conclusions will be made at the end of the treatment analysis of the respective patient groups.
