【摘要】：目的应用64层螺旋CT门静脉期成像,分析胰源性门静脉高压侧支循环的特征。资料与方法回顾性分析2013年8月-2015年5月于西南医科大学附属医院诊断并经病理证实的52例胰源性门静脉高压患者的CT门静脉期图像,观察其侧支循环情况。结果 52例患者中孤立性脾静脉阻塞(ISVO)21例,非孤立性脾静脉阻塞(NISVO)31例,两者发生率差异无统计学意义(χ~2=1.92,P0.05)。侧支循环通路的主要途径为I型28例、Ⅱ型2例、Ⅲ型22例,Ⅰ、Ⅲ型侧支循环通路均显著多于Ⅱ型,差异有统计学意义(P0.01)。发生胃网膜静脉曲张48例高于其他静脉曲张的发生率(P0.001),发生胃底静脉曲张11例、食管下段静脉曲张1例,两者差异有统计学意义(χ~2=9.42,P0.01)。NISVO患者中胃底静脉和结肠右上静脉曲张发生率明显大于ISVO患者,差异有统计学意义(χ~2=4.15、7.44,P0.05)。结论多层螺旋CT显示胰源性门静脉高压侧支循环具有一定的特征性。
[Abstract]:Objective to analyze the characteristics of collateral circulation of pancreatic portal hypertension by 64 slice spiral CT imaging. Materials and methods the CT portal phase images of 52 patients with pancreatic portal hypertension diagnosed and pathologically confirmed in the affiliated Hospital of Southwest Medical University from August 2013 to May 2015 were retrospectively analyzed and the collateral circulation was observed. Results there were 21 cases of isolated splenic vein occlusion with (ISVO) and 31 cases of non-isolated splenic vein occlusion with (NISVO). There was no significant difference between the two groups (蠂 2 / 1.92 P 0.05). The main pathway of collateral circulation pathway was type I in 28 cases, type 鈪，
