RESUMO
Objective To analyze the clinical features and prognosis of patients with acute epidural hematoma in the whirlpool sign.Methods 36 cases of CT scan showed a whirlpool sign of acute subdural hematoma patients were selected as the observation group.During the same time period,50 acute epidural hematoma patients without the whirlpool sign were selected as the control group.All patients received operation treatment.The Glasgow coma score (GCS),amount of hemorrhage and prognosis were compared between the two groups.Results The preoperative GCS score of the observation group was significantly lower than that of the control group (P ＜ 0.05).In the operation,the blood loss of the observation group was significantly increased compared with the control group (t =3.232,3.164,P ＜ 0.05).Control group CT evaluation of preoperative and intraoperative measurement had no significant difference(P ＞0.05).In the observation group,11 patients died,the mortality rate was 30.5％ (11/36).In the control group,6 patients died,the mortality rate was 12.0％ (6/50),the difference between the two groups was statistically significant (x2 =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 the control group (x2 =3.989,P ＜ 0.05).Conclusion Acute epidural hematoma patients with thewhirlpool signshowed progressive disease,high mortality,poor prognosis,and active countermeasures should be taken.
