Abstract:

Aim: was to identify and analyze key factors affecting the outcome of subarachnoid hemorrhage (SAH) in patients with ruptured cerebral aneurysms and endovascular embolization.

Materials and methods: as a material for this study, results of endovascular treatment of 150 patients with ruptured cerebral aneurysms operated in the acute period of subarachnoid hemorrhage were analyzed.

Results: statistically significant factors influencing the target indicator «Unfavorable outcome» on the Rankin scale (mRs 3-5) and the indicator «Fatal outcome» in patients with SAH who underwent endovascular method were identified. Among factors contributing to an unfavorable outcome are: severity of neurological status, prevalence of SAH according to computed tomography (CT), timing of surgical treatment from the moment of onset of SAH symptoms.

Conclusion: factors of severity of the condition on the Hunt-Hess scale (HH), severity of subarachnoid hemorrhage on the Fischer scale (F) and timing of the operation have the greatest influence on the outcome of subarachnoid hemorrhage of aneurysmal genesis.
