摘　　要：目的　探讨胰源性门静脉系节段性阻塞 (PSOPS)的CT征象。材料与方法　回顾性分析 3 3例PSOPS患者的螺旋CT表现 ,同时以 2 0例无门静脉系阻塞的病例作对照。 3 3例PSOPS中 ,包括脾静脉阻塞 (SVO) 2 7例和肠系膜上静脉阻塞 (SMVO) 6例。结果　在SVO中 ,胃左静脉、胃短静脉、胃网膜静脉、胃结肠干曲张或扩张的比例分别为 70 %、78%、83 %、5 6%。在SMVO中 ,胃结肠干、结肠右上静脉扩张比例均为 67%。结论　PSOPS有较特征性的侧支循环静脉开放 ,这些侧支静脉对PSOPS的CT诊断和临床治疗有重要意义。Objective To study the spiral CT features of pancreatogenic segmental occlusion of portal system (PSOPS).Materials and Methods Spiral CT findings of PSOPS in 33 cases, including 27 cases with splenic vein occlusion (SVO) and 6 cases with superior mesenteric vein occlusion (SMVO), were retrospectively analyzed, and were compared with 20 cases without PSOPS.Results In SVO cases, varicose or dilated gastric left vein (70%), gastric short vein (78%), gastroepiploic vein (83%) and gastrocolic trunk (56%) could be seen, while in SMVO cases, 67% of both gastrocolic trunk and right superior colic vein were dilated.Conclusion PSOPS develops collateral vessels, which are very characteristic on CT and very helpful for the clinical diagnosis and management.
