頭顱CT漩渦征對(duì)創(chuàng)傷性硬膜外出血血腫擴(kuò)大的預(yù)測(cè)價(jià)值
[Abstract]:Objective to evaluate the predictive value of CT whirlpool sign in predicting the enlargement of traumatic extradural haematoma. Methods Seventy-five patients with traumatic epidural hematoma in our hospital were examined by CT within 6 hours after injury. They were divided into positive group and negative group according to their existence and no whirlpool sign. 24 hours after onset or when the condition worsened, the brain CT, was routinely reexamined. According to the multi-field formula, the epidural hematoma volume was calculated and the incidence of hematoma enlargement was compared between the two groups. Results of the 75 patients, 40% (30 / 75) and 60% (45 / 75) were found vortex sign in CT positive group, 37.3% (28 / 75) in hematoma enlargement group, 89.3% (25 / 28) in whirlpool positive group, 30% (30 / 75) in negative group, 60% (45 / 75) in negative group, and 87.3% (25 / 28) in whirlpool sign positive group, respectively. The incidence of hematoma enlargement in the negative group was 10.7% (3 / 45), and there was a significant difference between the two groups (蠂 2, 25.72, P0.01). Conclusion CT whirlpool sign can be used as an imaging index to predict the enlargement of acute traumatic epidural hematoma.
