Journal Title:Basic Research Journal of Medicine and Clinical Science

Background: The purpose of current study is to determine the relationship between vasospasm risk factors following aneurysmal subarachnoid hemorrhage and changes in flow velocity of middle cerebral artery (MCA) through Ultrasonography Transcranial Doppler (TCD). Methods: The present descriptive-analytical study was conducted on 21 of vasospasm patients who were qualified for inclusion underwent study. Number and severity of the risk factors present in each individual, values of MCA Flow Velocity (MCAFV) achieved by TCD and results of examinations were recorded in each turn. Results: It is reported that in investigating by TCD in 38.8% of participants, Modified fisher grade was low, in 59.1% Hunt and Hess grade was average, GCS was between 10 to 15, in 36.4% there was hypertension history, in 40.9% of them aneurysm size was between 2.25 cm . Diastolic blood pressure on admission was between "100 to 118", aneurysm size mean was 2.25 cm and maximum flow velocity of LMCA, LACA, RACA and RMCA is more than 120. Conclusions: Vasospasm risk factors after aneurysmal SAH and Changes in MCA Flow Velocity using TCD showed a significant relationship with age, Modified fisher grade, Hunt and Hess grade, HTN, GCS and aneurysm size.
