| Summary: | Background/Aim. Intracranial aneurysms are pathological enlargement of the
wall of cerebral arteries. Intracranial aneurysms rupture is a dramatic event
with a significant morbidity and mortality. The Fisher Grade is widely
accepted in assessment of the extensiveness of aneurysmal subarachnoid
hemorrhage (aSAH) and the presence of other intracranial hemorrhage on the
computed tomography (CT) scan. Significant early complication of a aSAH may
be a cerebral vasospasm. The aim of this study was to determine the
relationship between the extensiveness of aSAH, assessed by the Fisher Grade
on admission, with the intensity of cerebral vasospasm in patients with
ruptured intracranial aneurysm. Methods. This prospective clinical study
included 50 patients with aSAH hospitalized at the Clinic of Neurosurgery,
Clinical Center of Vojvodina, Novi Sad, Serbia. All the patients underwent
256-layer cranial CT and CT angiography on admission and on the day 9. Based
on native CT scans, they were classified according to the Fisher Grade. On CT
angiography images, intensity of cerebral vasospasm was determined. Results.
On the basis of admission CT images, 24% of patients were classified into the
Fisher Grade group 2, while 34% and 42% were in the groups 3 and 4,
respectively. A positive correlation of the Fischer Grade on admission with
the intensity of cerebral vasospasm was established, but with no statistical
significance (ρ = 0.273, p = 0.160). Conclusion. This study showed that the
Fisher Grade is not significant in predicting the intensity of cerebral
vasospasm in patients hospitalized with intracranial aneurysm rupture. |
