Abstract:
Objective To analyze the incidence of cerebral vasospasm (CVS) in patients with traumatic subarachnoid hemorrhage(t-SAH), time windows of CVS as well as the risk factors. Method A total of 98 patients,with t -SAH admitted from June 2007 to December 2008, were enrolled for this prospective study. The hemodynamics of middle cerebral artery (MCA) in these patients was monitored with trancranial Doppler (TCD) daily for 7 days after admission and on the 14th day of hospital stay. The incidence of cerebral vasospasm (CVS) in patients with traumatic subarachnoid hemorrhage (t-SAH) ,time windows of CVS as well as the risk factors were analyzed. Results Of them, 41 patients (41.8%) had CVS. The flow velocity of MCA in patients with GCS≤ 8 was significantly higher than that in patients with GCS≥9. Classified by t-SAH cumulative blood Hijdra method, 2(4.44%) of 45 patients(45.9%)with scores 6 or less,9 (29.0%)of 31 patients (37.8%) with scores 6～ 13,and 8 (36.4%) of 22 patients (20.0%)with scores 13 or more had CVS. Severe CVS occurred in 13 (35. 1% )of 37 surgical patients (37.8%), and local cerebral infarction occurred in four surgical patients after symptomatic treatment. The flow velocity of the MCA was significantly higher in surgical patients than that in non-surgical patients 3 days after admission. Conclusions The severity of original trauma, bleeding, location of t-SAH and operation are the major risk factors to lead to CVS in patients with t-SAH. Attention should he paid to those risk factors during the treatment of patients with t-SAH.
