This is on anatomical study of the suprarenal arteries and their variations in 30 cadavers aimed at providing in a subsequent article the anatomical basis of arterial segments of the gland. The suprarenal glands were supplied by 3 main groups of suprarenal arteries: superior, middle and inferior. Only the superior and the inferior groups were present in all cases, since the middle vessels appeared in only 93.3% +/- 4.6 of the cases. The superior group included on each side 4 arteries in males and 5 in females; the middle group presented only 1 artery on each side in both males and females, and the inferior group exhibited on each side 2 arteries in males and 1 artery in females. The most variable group was the middle one, the aortic origin being the most frequent but with a relatively low incidence (53.3% +/- 9.1 on the right and 46.7% +/- 9.1 on the left). The superior group originated from the posterior branch of the ipsilateral inferior phrenic artery in 83.3% +/- 6.8 on the right and 80% +/- 7.3 on the left. The arteries of the inferior group were branches of the ipsilateral renal artery in 70% +/- 8.4 on the right and 50% +/- 9.1 on the left. The origin of the middle suprarenal arteries from the trunk of the inferior phrenic artery on both sides (26.7% +/- 8.1 on the right and 36.7% +/- 8.8 on the left) should be considered relevant. The anatomical findings warrant a further investigation for the identification, illustration and nomenclature of arterial anatomicosurgical segments.
这是一项对30具尸体肾上腺动脉及其变异情况的解剖学研究，目的是在后续文章中为肾上腺动脉各段提供解剖学基础。肾上腺由3组主要的肾上腺动脉供血：肾上腺上动脉、肾上腺中动脉和肾上腺下动脉。所有病例均存在肾上腺上动脉和肾上腺下动脉，因为肾上腺中动脉仅在93.3%±4.6%的病例中出现。肾上腺上动脉组在男性每侧有4支动脉，女性每侧有5支动脉；肾上腺中动脉组在男性和女性每侧均只有1支动脉；肾上腺下动脉组在男性每侧有2支动脉，女性每侧有1支动脉。变异最大的是肾上腺中动脉组，其最常见的起源是主动脉，但发生率相对较低（右侧为53.3%±9.1%，左侧为46.7%±9.1%）。肾上腺上动脉组右侧83.3%±6.8%、左侧80%±7.3%起源于同侧膈下动脉后支。肾上腺下动脉组右侧70%±8.4%、左侧50%±9.1%是同侧肾动脉的分支。双侧肾上腺中动脉起源于膈下动脉主干的情况（右侧为26.7%±8.1%，左侧为36.7%±8.8%）应予以关注。这些解剖学发现值得进一步研究，以明确动脉解剖手术段的识别、图示和命名。
