摘　　要：目的探讨起源于腹主动脉的膈下动脉(inferiorphrenicartery,IPA)与腹腔干的位置关系是否存在规律。资料与方法连续观察200例行Philips256层螺旋CT双期增强扫描(腹部174例,胸腹联合26例)患者IPA起源、起源于腹主动脉的IPA开口与腹腔干开口的位置关系。结果 200例患者右膈下动脉(rightinferiorphrenicartery,RIPA)均显示,共201支;198例患者左膈下动脉(leftinferiorphrenicartery,LIPA)显示,2例LIPA未显示,共203支。IPA左右共干起源占24.0(48/200)。RIPA起自腹腔干占34.8(70/201),腹主动脉占40.8(82/201),右肾动脉占18.4(37/201),右副肾动脉占2.0(4/201),胃左动脉占4.0(8/201);LIPA起自腹腔干占55.7(113/203),腹主动脉占37.9(77/203),胃左动脉占5.4(11/203),脾动脉占1.0(2/203)。起源于腹主动脉的IPA(135例)开口与腹腔干关系存在规律:①98.3(57/58)的RIPA位于腹主动脉壁9～12点位置,LIPA及共干IPA均位于腹主动脉壁12～3点位置;②80.0(108/135)的IPA开口位于腹腔干开口上下10mm以内,其余20.0(27/135)均位于腹腔干开口下10mm以外。③63.8(37/58)的RIPA开口在腹腔干开口下方,43.4(23/53)的LIPA及54.2(13/24)的共干起源的IPA开口在腹腔干开口上方。④IPA开口位置越接近腹主动脉壁9点或3点位置时,其与腹腔干开口的距离越大,86.8(46/53)开口位于腹腔干开口下方;开口位置接近腹主动脉壁12点位置时,52.5(42/80)的IPA开口位于腹腔干上方。结论起源于腹主动脉的IPA与腹腔干的位置关系存在规律,结合这一规律,可简化血管介入科医师插管流程,更快捷、准确地找到IPA。Purpose To explore whether there are some rules in the relationship between inferior phrenic artery（IPA） originated from the abdominal aorta and the celiac trunk.Materials and Methods The origin of IPA in 200 patients（174 with abdomen scan and 26 with chest-abdomen scan） who underwent two-phase enhanced CT scan at Philips 256-slice helical CT were respectively observed.The relationship of the orifice position between IPA originated from the abdominal aorta and the celiac trunk was analysed.Results RIPA was shown in 200 cases with total 201 branches.LIPA was shown in 198 cases with total 203 branches.2 cases of LIPA were not shown.Bilateral IPA originated from a common stem was seen in 48 of 200 cases（24）.RIPA originated from the celiac trunk in 70/201 cases（34.8）,from the aorta in 82/201 cases（40.8）,from the right renal artery in 37/201cases（18.4）,from the right accessory renal artery in 4/201cases（2.0） and from the left gastric artery in 8/201 cases（4）.LIPA originated from the celiac trunk in 113/203 cases（55.7）,from the aorta in 77/203 cases（37.9）,from the left gastric artery in 11/203 cases（5.4） and from the spleen artery in 2/203 cases（1.0）.There are some rules in the relationship between the origin of IPA originated from the abdominal aorta（135cases） and the celiac trunk：① 98.3 of RIPA located in the 9-12 o’clock position relative to the wall of the aorta.LIPA and IPA which originated from a common stem located in the 12-3 o’clock position relative to the wall of aorta ;② 80.0 of IPA had orifice located 10mm upper or lower of the orifice of the celiac trunk,and the remaining located 10mm lower than the orifice of the celiac trunk.③ 63.8 of RIPA had the orifice located under the orifice of the celiac trunk.43.4 of LIPA and 54.2 of IPA which originated from a common stem located upper than the orifice of the celiac trunk.④ 86.8 of IPA had the orifice located under the orifice of the celiac trunk.The nearer the orifice of IPA to the 9 or 3 o’cl
