目前关于乳头乳晕复合体（NAC）血液供应的知识主要来自对尸体或乳房正常大小的人的研究。本研究的目的是通过计算机断层扫描血管造影（CTA）检查对患有乳房肥大的女性志愿者的NAC血供进行识别和分类。对23名女性受试者的肥大乳房进行了CTA检查。通过图像数据分析揭示了主要的血液供应。 NAC 的主要血液供应及其血管来源已被识别和分类。血管可检测直径阈值设置为1.0毫米以上。共识别出61条优势血管。追踪来源动脉为胸廓内动脉（ITA，50.8%）、胸外侧动脉（LTA，27.8%）、胸肩峰动脉（TA，14.8%）、肱动脉（BA，3.3%）和腋动脉（AA，3.3%），这些来源血管相应的重复性为31、37、9，在所有乳房中，分别为 4.3% 和 4.3%。在任何 CTA 扫描图像中，肋间动脉 (IA) 均未被识别为主要的 NAC 供应血管。 26 个乳房只有一根主要动脉，而 17 个乳房显示出多个主要血液供应。三个乳房未显示 NAC 的优势血管，其直径大于可检测阈值 1.0 mm，并且 52.2% 的乳房表现出 NAC 血液供应的解剖学对称模式。根据研究的乳房，ITA、LTA 和 TA 可能是主要血管来源，而 IA 不太可能是 NAC 灌注的主要血管。在这项研究中，相当一部分患有乳房肥大的女性证实了双侧乳房血液供应的不对称模式。该杂志要求作者为每篇文章分配一定程度的证据。有关这些循证医学评级的完整说明，请参阅目录或在线作者须知。
Current knowledge about the blood supply of the nipple-areola complex (NAC) has largely been derived from studies on cadavers or persons with breasts of normal size. The aim of this study was to identify and classify the NAC blood supply by computed tomographic angiography (CTA) examination in female volunteers with breast hypertrophy.CTA examination was performed on hypertrophic breasts of 23 female subjects. The main blood supplies were revealed through image data analyses. The dominant blood supply of the NAC and its vascular sources were identified and sorted. The detectable diameter threshold of blood vessels was set beyond 1.0 mm.A total of 61 dominant blood vessels were identified. The source arteries were traced as the internal thoracic artery (ITA, 50.8%), lateral thoracic artery (LTA, 27.8%), thoracoacromial artery (TA, 14.8%), brachial artery (BA, 3.3%), and axillary artery (AA, 3.3%), and the corresponding reproducibility of these source vessels was 31, 37, 9, 4.3, and 4.3%, in all breasts. The intercostal artery (IA) was not identified as a dominant NAC supplying vessel in any CTA scan image. Twenty-six breasts had only one dominant artery, whereas 17 breasts showed multiple dominant blood supplies. Three breasts showed no dominant blood vessels of the NAC, with diameters greater than the detectable threshold of 1.0 mm, and 52.2% of the breasts demonstrated anatomically symmetrical patterns of blood supply for the NAC.The ITA, LTA, and TA are likely to be the main vessel sources, whereas the IA is unlikely to be the dominant vessel for NAC perfusion, on the basis of the studied breasts. An asymmetrical pattern of bilateral breast blood supply was demonstrated in a considerable portion of the females with breast hypertrophy in this study.This journal requires that authors assign a level of evidence to each article.
