Purpose
Intracranial aneurysms remain one of the main cause for non-traumatic subarahnoid hemorrhage (SAH) and drive up to 80-85% of all intracranial hemorrhages.
The treatment outcomes among patients with SAH remains poor,
with population-based mortality rates 45% and significant morbidity among survivors.
The severity of the patient's condition and prognosis in the pre-and postoperative periods depends on volume and localization of intracranial hemorrhages,
as well as development of cerebral vasospasm with following ischemia,
which represents the leading cause of death and disability in patients who survives the initial event.
The prevalence of vasospasm during the first 2 weeks following SAH is 70%,
that is why early recognition and prompt treatment of this condition can improve the outcomes.
Traditional methods for vasospasm diagnostics include transcranial Doppler ultrasonography (TCD) followed by routine computer tomography (CT) which allows performing an accurate assessment of cerebral infarction and choosing the optimal time for surgical intervention,
predicting the risk of development and/or growing of vasospasm after surgery.
The aim of the research was to conduct a comparative analysis of the TCD and CT data among patients with ruptured intracranial aneurysms before and after operation
