Abstract:
Objective To explore the value of transcranial Doppler ultrasonography (TCD) on diagnosing the cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH). Methods TCD was used to detect and monitor the cerebral blood flow status to estimate CVS following SAH in 30 cases, then the results of TCD were analyzed by combining with clinical manifestation and SAH severity on CT. Results 17 patients (56.7%) had the evidence of CVS confirmed by TCD, 10 of them were nonsymptomatic and 7 were symptomatic. The incidences of CVS in patients with Fisher grade Ⅲ and Ⅳ were more higher than gradeⅠandⅡ(P
