【摘要】 用从初生至身长150cm的童尸180具(分为6组),观察了小儿门静脉的汇合状况.测量了小儿门静脉及其主要属支的长度和外径等,并藉此探讨了小儿门静脉形态结构的年龄特征.主要结果为:(1)门静脉合成有三种类型,“π”型占56.1%、“F”型占 28.g%“K”型占15.0%,门脾角变动于76～128°之间,平均为103.618.7°(2)门静脉长度分别为16.0±3.2 22.5±6.0、29.6±6.9、35.1±10.7、39.1±8.2和412±7.7mm,直线回归方程为y((mm)=3.4056X(cm)～11.2466:门静脉外径分别为4.6±1、0、6.1±1.5、6.8±1.0、7.8±2.2、9.0±1.7和10.5±2.2mm,直线回归方程为y(mm)=15.967IX(cm)～27.2044.( 3)脾静脉和肠系膜上、下静脉的长度和外径的测量值与成人资料相衔接.更多还原

【Abstract】 One hundred and eighty corpses, with their lengths varying from 50 to 150 cm, were used and divided into 6 groups ( Ⅰ-Ⅵ ). The drainage position was observed and the length and diameter of the portal vein and its tributaries was measured. Based on the morphological data, the anatomical characteristics of the portal vein in children is discussed in this article. The main results of this study are as follows: (1) The portal vein are of three types: "p" type 56.1%, "F" type 28. 9%, "K" type 15.0%. The portal-splenic angle varies between 76°and 128°, averaging 103.6 ±18.7°.(2) The length of the portal vein in the six groups is 16.0±3.2, 22.5±6.0, 29.6±6.9, 35.1±10.7, 39.1 ±8.2 and 41.2 + 7. 7mm respectively; the liner regression equation is y (mm) = 3.4056x(cm)-11.2 460. The diameter of the portal vein is 4.6±1.0, 6.1±1.5, 6.8±1.0, 7.8±2.2, 9.0±1.7 and 10.5±2.2mm respectively; the liner regression equation is y (mm) =15.9671x(cm) -27.2044. (3) The length and diameter of such veins as the splenic vein, the superior and inferior mesenteric veins are agreeable to the data obtained from adults.更多还原
