Diagnostic value of transcranial doppler in the vasospasm secondary to middle cerebral artery aneurysmal haemorrhage

ABSTRACT

This study highlights the importance of transcranial dopper [TCD] study in suspected middle cerebral artery aneurysmal subarachnoid hemorrhage. Eight middle aged patients of either sex presented with acute history of severe headache to our department for Neuroradiological investigations. The TCD study on middle cerebral artery [MCA] was positive in all the cases, suggestive of vasospasm. In seven cases CT Scan brain and cerebral angiography showed middle cerebral aretery aneurysm with its segmental narrowing suggestive of vasospasm. In one, case neither CT scan nor cerebral angiography fully confirmed the middle cerebral artery aneurysm where as surgery correlated the TCD findings of vasospasm secondary to aneurysmal bleed. The TCD is an ideal and inexpensive method in suspected middle cerebral artery aneurysmal subarachnoid hemorrhage to have clue of the aneurysm and also to monitor vasospasm which may help in proper management
