Aim:
To compare the histological and angiographic measurements of the basilar artery in an experimental rabbit subarachnoid hemorrhage model.
Material And Methods:
The basilar artery was measured using both histological and angiographic methods in experimental subarachnoid hemorrhage (SAH) and vasospasm rabbit models. New Zealand white rabbits were randomly categorized into two groups: control and SAH groups. The SAH group rabbits were operated on to create an experimental SAH. Both groups were examined angiographic and histological methods.
Results:
On comparing the two methods, angiographic and histopathological measurements of the basilar artery were similar in the control group. However, in the SAH group, the difference between the angiographic and histopathological measurement methods was significant. Histopathological measurements of the basilar artery were lower than angiographic measurements, and the difference was statistically significant. In the angiographic method, although there was a marked decrease in basilar artery measurements in the SAH group, the differences between the groups was not statistically significant. However, in the histopathological method, measurement differences between the control and SAH groups were statistically significant.
Conclusion:
Histopathological measurements were shown to be more sensitive than angiographic methods in demonstrating cerebral vasopasm in experimental SAH rabbit models.
