摘　　要：目的探索多层螺旋CT血管造影(MSCTA)在胰源性区域性门静脉高压症(PSPH)的诊断价值。方法对38例PSPH患者行全腹部CT平扫及增强扫描,进行血管重建,分析脾静脉闭塞后侧支循环血管开放及曲张情况。结果 38例PSPH均表现为脾静脉闭塞。胃冠状静脉(GCV)未受累及32例中,胃短静脉(GSV)25例、胃冠状静脉(GCV)30例、胃网膜静脉(GEV)25例、胃结肠干(GCT)20例;GCV受累及6例中,均出现GCV、GSV、GEV曲张。结论 MSC-TA能清晰显示PSPH中脾静脉狭窄阻塞及侧支循环情况。Objective To explore the value of multi - slice spiral CT angiography （MSCTA） in diagnosis of pancreatic segmental portal hypertension （PSPH）. Methods Plain and enhanced whole abdominal scanning in 38 patients with PSPH had been performed. Then the blood vessels were reconstructed; and the conditions of patency and varices of splenic vein after occlusion and collateral vessels were analyzed. Results All 38 cases showed obstruction in splenic vein. Among them, 32 cases had no obstruction in gastric coronary vein （GCV） including gastric short vein （GSV） in 25 cases, GCV in 30 cases, gastroepiploic vein （GEV） in 25 cases and gastrocolic trunk （GCT） vein in 20 cases. In 6 cases with obstruction in gastric coronary vein, varices were observed in GCV, GSV and GEV. Conclusion MSCTA can demonstrate stenosis in splenic vein, obstruction and collateral vessels in patients with PSPH.
