摘　　要：目的应用16层螺旋CT肝门静脉成像(CTPV)技术,探讨肝硬化门脉高压侧支血管分流途径及其临床意义。方法收集并分析我院16层螺旋CT肝门静脉成像145例。进行常规平扫及三期增强扫描,三维重建方法采用MIP、VR、MPR。结果仅向上腔静脉引流45例(31%);仅向下腔静脉引流11例(7.7%);分别向上、下腔静脉引流89例(61.3%)。结论 CTPV可显示肝硬化门脉高压患者的门-体静脉之间各种侧支循环血管,有助于对门脉高压患者上消化道出血等合并症选择合理治疗方案及进行疗效随访。Objective To explore the collateral shunt pathways of cirrhotic portal hypertension and analyse the clinical significances in CTPV with 16-MDCT. Methods 145 patients with cirrhotic portal hypertension were analysed who un- derwent CTPV in 16-MDCT. Routine plain scans and post-triphase enhancement CT scans were performed. Post^process- ing including MIP, VR, MPR were done. Results The collateral shunt pathways were forty-five superior vena cava （31%） purely, eleven inferior vena cava （7.7%） purely, eighty-nine （61.3 ~/0） superior vena cava and inferior vena cava bidirectionally. Conclusion CTPV could clearly reveal all kinds of the porto-caval collateral shunt for cirrhotic portal hy- pertension, which is helpful to the treatment and following up for the complications of cirrhotic portal hypertension such as upper gastrointestinal bleeding.
