Abstract

Background: The aim of this study was to provide a detailed analysis of the topographical anatomy of the inferior epigastric artery (IEA), including its origin pattern, morphometric parameters, spatial relationships to anatomical landmarks and perforating branches.

Materials and methods: Data from 75 patients who underwent computed tomographic angiography of the abdomen and pelvis were analyzed. A total of 142 sides that met the eligibility criteria were evaluated.

Results: The IEA was found to originate from the external iliac artery in 110 cases (77.5%), in 22 cases (15.5%) it had a common trunk with the obturator artery, in 9 cases (6.3%) it originates from the femoral artery, and in one case (0.7%) from the deep femoral artery. The median diameter of the IEA at its origin was 3.12 mm, while its cross-sectional area was 5.97 mm². The median distance between the origin of the source artery to the origin of the IEA was 8.46 mm. The number of perforators varies per patient side from 2 to 7, with the most common direction of their origin being the medial direction.

Conclusions: The most common origin was the external iliac artery (77.5%), although a common trunk with the obturator artery was also observed relatively often (15.5%). The IEA originated most commonly in the medial direction (93.0%). A key focus was on the perforators, with a median of 2 per side and up to 7 observed. The first perforator that could be used in the deep inferior artery perforator (DIEP) flap had a mean diameter of 1.71 mm and was located approximately 64.6 mm from the IEA origin and 95.3 mm from the umbilicus. The obtained results may find clinical application during pedicle preparation during DIEP flap elevation and in penile revascularization procedures.

腹壁下动脉及其穿支在计算机断层血管造影中的地形解剖——对重建手术的意义。
背景:本研究的目的是详细分析腹壁下动脉(IEA)的地形解剖学,包括其起源模式,形态计量参数,与解剖标志和穿支的空间关系。材料和方法:对75例腹部和骨盆计算机断层血管造影患者的资料进行分析。对符合资格标准的142个方面进行了评估。结果:IEA起源于髂外动脉110例(77.5%),与闭孔动脉有共干22例(15.5%),起源于股动脉9例(6.3%),起源于股深动脉1例(0.7%)。IEA原点直径中位数为3.12 mm,横截面积为5.97 mm²。源动脉起始点至IEA起始点的中位距离为8.46 mm。每侧穿支的数量从2到7不等,最常见的方向是内侧。结论:最常见的起源是髂外动脉(77.5%),尽管与闭孔动脉共干也比较常见(15.5%)。国际能源署最常见的来源是中间方向(93.0%)。重点是射孔器,每侧中位数为2个,最多可观察到7个。第一个可用于深下动脉穿支(DIEP)皮瓣的穿支平均直径为1.71 mm,位于距IEA起源约64.6 mm和距脐95.3 mm处。所获得的结果可在DIEP皮瓣提升和阴茎血运重建过程中找到临床应用。

期刊介绍: "Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
