【摘要】：目的解剖肝動(dòng)脈,分析其變異規(guī)律,以期為臨床提供形態(tài)學(xué)基礎(chǔ)。方法隨機(jī)選取74具尸體,充分解剖暴露腹腔動(dòng)脈及其分支,對(duì)肝動(dòng)脈的起源、行徑進(jìn)行仔細(xì)觀察和記錄。結(jié)果本研究觀察到Hiatt六種分型中的三種:Ⅰ型正常型占77.02%(57例):肝總動(dòng)脈起于腹腔干,分為胃十二指腸動(dòng)脈和肝固有動(dòng)脈,后者又分為肝左、中、右動(dòng)脈;Ⅱ型占9.47%(7例):替代性或副的肝左動(dòng)脈起于胃左動(dòng)脈;Ⅴ型占1.35%(1例):肝總動(dòng)脈起于腸系膜上動(dòng)脈。除此之外,還觀察到三種罕見(jiàn)的類型:Ⅶ型占6.76%(5例):替代性肝左動(dòng)脈起于肝總動(dòng)脈;Ⅷ型占2.70%(2例):替代性肝右動(dòng)脈起于胃十二指腸動(dòng)脈;Ⅸ型占2.70%(2例):替代性肝左動(dòng)脈與胃及食管的動(dòng)脈分支共干,在本研究中,稱其為共干動(dòng)脈,起于腹腔動(dòng)脈。結(jié)論本研究在小樣本中觀察到3種罕見(jiàn)的變異類型,提示肝動(dòng)脈變異具有極大的復(fù)雜性和偶然性。臨床醫(yī)生對(duì)此應(yīng)予以高度重視。
