Abstract

Summary:


The aim of the study is to analyze and establish the relation between mean arterial pressure (MAP) and cerebral blood supply, respectively, cerebral vasospasm, in patients operated for non-ruptured cerebral aneurysms in the early postoperative period by measuring the Lindegaard ratio.

Materials and methods:

The study included 48 patients operated on non-ruptured brain aneurysms for the period from May 2018. until June 2019. The patients were divided into two groups, depending on the MAP values ​​and the use of catecholamines in the early postoperative period, with the Lindegaard ratio measured by transcranial Doppler ultrasound.

Results:

Depending on the values ​​of MP, patients are divided into two groups: MBP 70-90 mm / Hg and 90 mm / Hg. Better brain perfusion was reported in the 90 mm / Hg group with 23.23%, respectively, a lower Lindegaard ratio, despite better results in comparing the two groups of patients, the improvement in cerebral blood flow was not statistically significant, p value  < 0.5. Depending on the use of catecholamines in the early postoperative period, we divide patients into two groups: with and without catecholamine . In the catecholamine - treated group, brain perfusion was reported to be better by 32.14%, despite these results, comparing the two groups of patients,
improvement in cerebral blood supply was not statistically significant with  p value  <0.5.
