目的分析胰源性区域性门静脉高压(pancreatogenic segmental portal hypertension,PSPH)的多层螺旋CT(MSCT)表现和特征。方法对32例胰源性门静脉高压患者,使用16排多层螺旋CT行上腹部CT平扫、多期相增强扫描,采用多平面重组(MPR)、最大密度投影(MIP)、容积再现(VR)等图像后处理技术显示异常的脾静脉及侧枝血管情况。结果脾静脉均有受压、血栓或受侵表现,孤立性脾静脉阻塞中,食管静脉(EV)、胃短静脉(SGV)、胃冠状静脉(CGV)、胃网膜静脉(GEV)、胃结肠干(GCT)曲张分别占9.37%,67.65%,65.63%,96.88%,28.13%;非孤立性脾静脉阻塞伴有肠系膜上静脉SMV阻塞时,其属支结肠右上静脉(RSCV)、胃结肠干(MCV)、胰十二指肠前上静脉(ASPDV)曲张例数分别为15.63%,18.75%,5.88%。同时伴门静脉海绵样变5例。结论MSCT及图像后处理系统对PRPH诊断具有重要价值。
Objective To analyze the multi-slice spiral CT (MSCT) features and features of pancreatogenic segmental portal hypertension (PSPH). Methods Thirty-two patients with pancreatic portal hypertension were examined with multi-slice CT (MPR), maximum density projection (MIP) and volume rendering (VR) ) And other image post-processing techniques showed abnormal splenic vein and collateral vessels. Results The splenic vein was under compression, thrombus or invasion, isolated splenic vein obstruction, esophageal vein (EV), short gastric vein (SGV), gastric coronary vein (CGV), gastric venous vein (GEV) The rates of GCT were 9.37%, 67.65%, 65.63%, 96.88%, 28.13% respectively. When non-isolated splenic vein obstruction was accompanied by SMV obstruction of superior mesenteric vein, the colorectal upper right vein (RSCV) The number of cases of MCV and ASPDV were 15.63%, 18.75% and 5.88% respectively. At the same time with portal vein sponge-like change in 5 cases. Conclusion MSCT and image post-processing system are of great value in the diagnosis of PRPH.
