摘要
本文调查76具尸体,61例有胃后动脉,出现率为80.26±4.56%。胃后动脉起于脾上极动脉31例,占50.82±6.40%;起于脾动脉26例;占42.62±6.33%;起于脾动脉及脾上极动脉2例;占3.28±2.38%;起于胰尾动脉1例,占1.64±1.62%,起于胃左动脉1例,占1.64±1.62%。胃后动脉按支数可分四型:1支型,占75.41±5.51%;2支型,占18.03±4.92%;3支型,占4.92±2.77%;4支型,占1.64±1.62%。该动脉外径平均为1.42±0.43mm。胃后动脉于腹膜后间隙向左上斜行,经膈胃韧带入胃后壁,距胃底缘2.07±0.70 cm,距贲门左侧为2.68±0.94 cm。分布于胃体上部近贲门侧及食管腹段后面。
This investigation was performed in 76 cadavers.The posterior gastric artery was found in 61 cases(80.26±4.56 percent).The posterior gastric artery originates from the superior polar artery in 31 eases(50.82±6.40 percent),from the splenic artery in 26 cases(42.62±6.33 percent),from the splenic artery and the superior polar artery in 2 cases(3.28±2.38 percent),from the panereatic caudal artery in 1 case and left gastric artery in 1case(1.64±1.62 percent).Their average outer diameter is 1.42±0.43 mm.
