The internal iliac artery stands as the main blood supplier of the pelvis, serving as the primary source of blood for the pelvic viscera while also nourishing the musculoskeletal framework within. The arterial anatomy of the pelvis exhibits a vast array of variations, especially regarding the branching pattern of the internal iliac arteries. The posterior division of the internal iliac artery (PDIIA) may also have variable topography, especially regarding the location of its origin in the pelvic region.
A retrospective study was carried out to determine the anatomical variations, prevalence, and morphometric data of the PDIIA and its branches. A total of 75 computed tomography angiographies were analyzed.
The most prevalent branch of the PDIIA was the superior gluteal artery, as it was present in 114 of the studied cases (77.03%). The median diameter of the PDIIA at its origin was 6.66 mm. The median cross-sectional area of the PDIIA at its origin was set to be 34.59 mm.
Our study highlights the critical significance of understanding the PDIIA and its branches in surgical interventions aimed at managing pelvic hemorrhage. The present study provides valuable insights into the precise localization and characteristics of the PDIIA and its branches, which are essential for surgical procedures targeting specific vessels to control bleeding effectively. Owing to the high level of variability of the branching pattern of the PDIIA, a novel classification system consisting of six types was created.
髂内动脉是骨盆的主要血液供应者，是盆腔脏器的主要血液来源，同时也滋养着盆腔内的肌肉骨骼结构。骨盆的动脉解剖结构存在大量变异，尤其是髂内动脉的分支模式。髂内动脉后支（PDIIA）的局部解剖也可能存在变异，特别是其在盆腔区域的起源位置。
开展一项回顾性研究，以确定PDIIA及其分支的解剖变异、发生率和形态学数据。共分析了75例计算机断层血管造影。
PDIIA最常见的分支是臀上动脉，在所研究的病例中有114例出现（77.03%）。PDIIA起始处的中位直径为6.66毫米。PDIIA起始处的中位横截面积设定为34.59平方毫米。
我们的研究强调了在旨在控制盆腔出血的外科手术中了解PDIIA及其分支的关键意义。本研究为PDIIA及其分支的精确定位和特征提供了有价值的见解，这对于针对特定血管进行手术以有效控制出血至关重要。由于PDIIA分支模式的高度变异性，创建了一个由六种类型组成的新分类系统。
