Abstract
Subarachnoid hemorrage (SAH) is common emergency in patients who got the congenital or acquaired cranio-vascular
diseases. This results from some reasons such as: aneurysm ruption, AVM or trauma. Vasospasm increases disability and
mortality in patients who have SAH. Transcranial Doppler Ultrasound (TCD) is the good method to diagnose early this stage
with many advantages as non-invasive, cheaply, the sensitivity and specification is rather high.
Purpose: 1. Evaluating the vasospasm after SAH by TCD; 2. Researching the correlation between the level SAH as well as the
clinical state of patients and the velocity blood flow of the middle cerebral artery recorded by TCD. Subjects and methods: We have prospected 20 patients who were diagnosed SAH on Computed tomography. TCD was performed 2 times: the 3rd – 4th day and the 8th – 9th day after getting SAH. Those whose peak systolic velocity in middle cerebral artery was ≥ 120cm/s considered vasospasm. Their clinical states were also recorded at the same times.
Results: 2 patients (10%) got vasospasm of MCA at the 8th – 9th day after SAH. The correlation between the level SAH as well
as the clinical state of patients and the velocity blood flow of MCA is unclosed.
Conclusion: TCD can detect early the vasospasm but the accuracy of this method is higher in the patients whose SAH is
primary and non - operated.
