【摘要】：目的應用64層螺旋CT門靜脈期成像,分析胰源性門靜脈高壓側支循環(huán)的特征。資料與方法回顧性分析2013年8月-2015年5月于西南醫(yī)科大學附屬醫(yī)院診斷并經病理證實的52例胰源性門靜脈高壓患者的CT門靜脈期圖像,觀察其側支循環(huán)情況。結果 52例患者中孤立性脾靜脈阻塞(ISVO)21例,非孤立性脾靜脈阻塞(NISVO)31例,兩者發(fā)生率差異無統(tǒng)計學意義(χ~2=1.92,P0.05)。側支循環(huán)通路的主要途徑為I型28例、Ⅱ型2例、Ⅲ型22例,Ⅰ、Ⅲ型側支循環(huán)通路均顯著多于Ⅱ型,差異有統(tǒng)計學意義(P0.01)。發(fā)生胃網膜靜脈曲張48例高于其他靜脈曲張的發(fā)生率(P0.001),發(fā)生胃底靜脈曲張11例、食管下段靜脈曲張1例,兩者差異有統(tǒng)計學意義(χ~2=9.42,P0.01)。NISVO患者中胃底靜脈和結腸右上靜脈曲張發(fā)生率明顯大于ISVO患者,差異有統(tǒng)計學意義(χ~2=4.15、7.44,P0.05)。結論多層螺旋CT顯示胰源性門靜脈高壓側支循環(huán)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，
