目的探讨三维对比增强磁共振血管成像(3D DCE MRA)在诊断胰源性区域性门静脉高压(PSPH)中的价值。方法23例PSPH患者行中上腹部3D DCE MRA,工作站上采用最大强度投影法(MIP)、多平面重建(MPR)、容积再现(VR)进行血管重建。结果23例PSPH均表现为脾静脉中断。侧枝循环血管:①胃冠状静脉(GCV)未受累及19例中,GCV13例、胃短静脉(GSV)19例、胃结肠干(GCT)11例、胃网膜静脉(GEV)19例可见曲张,脾-肾静脉交通1例;②GCV受累4例中,均出现GCV、GSV、GCT、GEV曲张,脾-肾静脉交通3例。结论3D DCE MRA能完整显示PSPH的异常血管细节。
Objective To investigate the value of three-dimensional contrast enhanced magnetic resonance angiography (3D DCE MRA) in the diagnosis of pancreatic regional portal hypertension (PSPH). Methods Twenty-three patients with PSPH underwent mid-upper quadrant 3D DCE MRA. The maximum intensity projection (MIP), multiplanar reconstruction (MPR) and volumetric reconstruction (VR) were performed on the workstation for revascularization. Results 23 cases of PSPH showed splenic vein interruption. Collateral circulation of blood vessels: ① gastric coronary vein (GCV) were not involved in 19 cases, GCV 13 cases, 19 cases of gastric short-vein (GSV), stomach and intestine dry (GCT) 11 cases, 19 cases of gastric venous veins (GEV) , Spleen - renal vein traffic in 1 case; ② GCV involvement in 4 cases, there GCV, GSV, GCT, GEV varicose veins, spleen - renal vein traffic in 3 cases. Conclusion 3D DCE MRA can completely display the abnormal blood vessels of PSPH.
