Clinical analysis of 36 cases with whirlpool acute epidural hematoma

Abstract

Objective To analyze clinical features and prognosis of patients with acute epidural hematoma in whirlpool sign. Methods 36 cases of CT scan showed awhirlpool sign of acute subdural hematoma patients were selected as observation group.During same time period,50 acute epidural hematoma patients without thewhirlpool sign were selected as control group.All patients received operation treatment.The Glasgow coma score(GCS),amount of hemorrhage and prognosis were compared between two groups. Results The preoperative GCS score of observation group was significantly lower than that of control group(P 0.05).In observation group,11 patients died,the mortality rate was 30.5% (11/36).In control group,6 patients died,the mortality rate was 12.0%(6/50),the difference between two groups was statistically significant(χ2= 4.134,P< 0.05).The patients were followed up for 6 months,the excellent and good rate of ADL score in observation group was 64.0%,which was significantly lower than 84.1% in control group(χ2= 3.989,P< 0.05). Conclusion Acute epidural hematoma patients with the whirlpool sign showed progressive disease,high mortality,poor prognosis,and active countermeasures should be taken.
