While alterations in the vasculature supplying the breast have been extensively recorded, there is no information on the direct breast branches of the axillary artery (AA). An elucidation of the direct breast branches may prove beneficial during mammoplasty.
This study sought to investigate the anatomical characterization of breast vasculature utilizing three-dimensional (3D) technology to establish an anatomical foundation for therapeutic operations.
Computed tomography images of 14 unilateral adult female breasts were conducted and rebuilt with Mimics software. The positioning of arteries in the breast area was also examined.
The most consistently observed arterial supply to the breast was the perforating branch from the internal thoracic artery (100%), followed by the anterior intercostal artery (78.6%), the direct breast branch from the AA (71.4%), and the indirect breast branch from the lateral thoracic artery (28.6%). The direct breast artery (DBA) was classified into two categories based on the angle of origin of the AA: direct branching from AA (type I 40 %) and at an angle (type II 60 %). Furthermore, 80 % of the DBA were noted to be positioned laterally to the thoracic dorsal artery.
3D technology accurately delineates the arterial distribution in the breast area at high resolution to inform clinical practice.

虽然对供应乳房的血管系统改变已有广泛记录，但关于腋动脉（AA）的直接乳房分支尚无相关信息。阐明直接乳房分支在乳房成形术中可能具有益处。
本研究旨在利用三维（3D）技术研究乳房血管系统的解剖特征，为治疗性手术建立解剖学基础。
对14例成年女性单侧乳房进行计算机断层扫描成像，并使用Mimics软件进行重建。还对乳房区域动脉的定位进行了检查。
最常观察到的乳房动脉供应是胸廓内动脉的穿支（100%），其次是肋间前动脉（78.6%）、腋动脉的直接乳房分支（71.4%）和胸外侧动脉的间接乳房分支（28.6%）。直接乳房动脉（DBA）根据腋动脉的起源角度分为两类：直接从腋动脉分支（I型，40%）和呈一定角度分支（II型，60%）。此外，80%的直接乳房动脉位于胸背动脉外侧。
3D技术能以高分辨率准确描绘乳房区域的动脉分布，为临床实践提供参考。
