摘　　要：应用双功能超声对34例肝外伤进行了诊断研究。并将其声像图特征分为Ⅲ型:Ⅰ包膜下血肿。呈无回声暗区型;Ⅱ真性破裂。呈混合型(强回声与低回声,或无回声与强回声等);Ⅲ中央型破裂。呈强回声光团或无回声区型。其超声诊断符合率为97%。双功超声除能提示正确诊断外,尚可观察外伤区血流动力学改变,能确定合并假性动脉瘤及动门静脉瘘的诊断。Thirty—four patients with liver injury were examined by duplex Doppler sonography. There were three types of liver injury according to the features of ultrasonography: (1) Capsular tears may revear an no—echo fluid sonolucent area; (2)Small laceration or sublobar fracture may reveal high—and low—echo, or no—echo sonolucent area; (3)Center fracture of hepatic parenchyma in one or two lobes may reveal high or no—echo sonolucent area. The diagnostic coincidence ratio of ultrasonic examination was 97%. To evaluate the possible liver injury, the Duplex doppler sonography may not only provide a right diagnosis, but also abserve the hemodynametic changes in injury area, and can demonstrate the presence of aneurysm and arterio—Portal vein fistula.
