目的 探讨微创血肿引流术对横窦骑跨性硬膜外血肿的治疗效果。方法 58例创伤性横窦骑跨性硬膜外血肿患者术前格拉斯哥昏迷评分(GCS）8～12分，均在CT定位下以YL-1微创引流针穿刺血肿腔，并以尿激酶50 000～60 000 IU冲洗引流。术后1 h、3 d及7 d行CT动态扫描，计算血肿量；术后3个月行格拉斯哥预后评分（GOS）。结果 CT显示术后1 h血肿量平均为（20±5）mL，术后3 d为(15±2) mL，均较术前的（45±15）mL显著减少（均P＜0.05）。术后3～5 d血肿均完全清除。术后5 d平均GCS为（12±1）分，较术前的（8±4）分显著提高（P＜0.05）。术后3个月GOS 5分（恢复良好）者45例（占78%），4分（中度残疾）者9例（占16%）。结论 微创血肿引流术对GCS≥8分的创伤性横窦骑跨性硬膜外血肿疗效确切，创伤小且操作简便。

Objective To investigate the therapeutic effect of minimally-invasive drainage on epidural hematoma straddling transverse sinus. Methods Fifty-eight patients with traumatic epidural hematoma straddling transverse sinus and preoperative Glasgow Coma Score (GCS) 8 to 12 points were managed with minimally-invasive drainage under CT location, and 50 000 to 60 000 IU of urokinase was used for irrigation and drainage. CT scanning was performed 1 h, 3 d and 7 d after operation, volumes of hematoma were calculated, and Glasgow Outcome Score (GOS) was evaluated 3 months after operation. Results The volumes of hematoma 1 h and 3 d after operation were (20±5) mL and (15±2) mL respectively, and were significantly lower than that before operation [(45±15) mL](P＜0.05). The hematoma was totally removed 3 to 5 d after operation. GCS was (12±1) points 5 d after operation, which was significantly higher than that before operation [(8±4) points](P＜0.05). Three months after operation, good recovery (GOS 5 points) was achieved in 45 patients (78%), and moderate disability (GOS 4 points) was found in 9 patients (16%). Conclusion Minimally-invasive drainage is effective in the treatment of traumatic epidural hematoma straddling transverse sinus with GCS≥8 points.
