Origins and distribution of the human inferior phrenic arteries were studied by dissecting 68 Japanese adult cadavers. The inferior phrenic arteries were usually observed as paired (left and right) vessels. Their origins were summarized as follows: a) the aorta itself (85/138 cases, 61.6%), b) the ventro-visceral arteries (celiaco-mesenteric system of the aorta) including the celiac trunk (39/138 cases, 28.2%) and the left gastric artery (4/138 cases, 2.9%), and c) the latero-visceral arteries (adreno-renal system of the aorta) including the middle adrenal artery (4/138 cases, 2.9%) and the renal artery (6/138 cases, 4.3%). The left and right arteries occasionally originated in common trunk from the aorta, celiaco-mesenteric system or adreno-renal system (22/138 cases, 15.9%). A typological diagram explaining these variations is given. The inferior phrenic arteries, especially the left ones, sometimes issued visceral or esophageal branches. This fact indicates that the inferior phrenic arteries are homologous with the celiac trunk and mesenteric arteries. It is further discussed that the celiac trunk and mesenteric arteries are originally paired vessels, through introduction of our previous typological diagram of the abdominal arteries.
通过解剖68具日本成年尸体，研究了人类膈下动脉的起源和分布。膈下动脉通常被观察为成对（左和右）血管。它们的起源总结如下：a）主动脉本身（85/138例，61.6%），b）腹侧内脏动脉（主动脉的腹腔-肠系膜系统），包括腹腔干（39/138例，28.2%）和胃左动脉（4/138例，2.9%），以及c）外侧内脏动脉（主动脉的肾上腺-肾系统），包括肾上腺中动脉（4/138例，2.9%）和肾动脉（6/138例，4.3%）。左、右动脉偶尔起源于主动脉、腹腔-肠系膜系统或肾上腺-肾系统的共同干（22/138例，15.9%）。给出了一个解释这些变异的类型图。膈下动脉，尤其是左膈下动脉，有时会发出内脏或食管分支。这一事实表明膈下动脉与腹腔干和肠系膜动脉同源。通过引入我们之前的腹部动脉类型图，进一步讨论了腹腔干和肠系膜动脉最初是成对的血管。
