Abstract：
BACKGROUND: The anatomy of the uterine artery (UA) is highly complex, demonstrating various patterns of origin and course. The main objective of the present study is to provide the first anatomical heat map of the UA, demonstrating the location of its origin and course in the pelvis.
METHODS: In July 2022, an assessment was conducted on the findings from 40 consecutive female patients who had undergone computed tomography angiography of the abdomen and pelvis. Morphometric features of the UA and its associated anatomical area were gathered in 19 categories.
RESULTS: The presented results are based on a total of 58 UAs. 40 UAs originated from the anterior trunk of the internal iliac artery (69.0%), 16 of the UAs originated from the umbilical artery (27.6%), and the remaining two originated from the inferior gluteal artery (3.4%). The median diameter of the UA at its origin was found to be 3.20 mm (LQ = 2.63; HQ = 3.89).
CONCLUSIONS: The anatomy of the UA is highly complex, showcasing variable topography, origin patterns, and morphometric properties. In the present study, a novel arterial map of this vessel was made, highlighting the diversity in its origin location and course. In our studied cohort, the UA originated most commonly from the anterior trunk of the internal iliac artery (69.0%), as described in the major anatomical textbooks. Having adequate knowledge about the anatomy of this artery is of immense importance in various gynecological and endovascular procedures, such as hysterectomies and embolizations.

摘要：
背景：子宫动脉（UA）的解剖结构非常复杂，展示各种起源和路线的模式。本研究的主要目的是提供UA的第一个解剖热图，展示其在骨盆中的起源和路线的位置。
方法：2022年7月，对40例接受腹部和骨盆计算机断层扫描血管造影的连续女性患者的发现进行了评估。在19个类别中收集了UA及其相关解剖区域的形态测量特征。
结果：给出的结果基于总共58个UA。40个UAs起源于髂内动脉前干（69.0%），其中16个UA起源于脐动脉（27.6%），其余两条起源于臀下动脉(3.4%)。UA在其起源处的中值直径为3.20mm(LQ=2.63;HQ=3.89)。
结论：UA的解剖结构非常复杂，展示可变地形，原点模式,和形态测量特性。在本研究中,制作了这条血管的新动脉图，突出其起源位置和路线的多样性。在我们研究的队列中，UA最常见于髂内动脉前干(69.0%),如主要解剖学教科书所述。在各种妇科和血管内手术中，对该动脉的解剖结构有足够的了解是非常重要的，如子宫切除术和栓塞。
