Symptomatic macromastia places a severe physical and psychological burden on patients. Reduction mammaplasty is the primary treatment; however, conventional surgery may lead to postoperative nipple-areolar complex necrosis due to damage to the dominant supplying arteries. In this study, we designed and fabricated an innovative, three-dimensional-printed breast vascular model to provide surgical guidance for reduction mammaplasty. Preoperative computed tomography angiography scanning data of patients were collected. The data were then processed and reconstructed using the E3D digital medical modeling software (version 17.06); the reconstructions were then printed into a personalized model using stereolithography. The three-dimensional-printed breast vascular model was thus developed for individualized preoperative surgical design. This individualized model could be used to intuitively visualize the dominant supplying arteries' spatial location in the breasts, thereby allowing effective surgical planning for reduction mammaplasty. The three-dimensional-printed breast vascular model can therefore provide an individualized preoperative design and patient education, avoid necrosis of the nipple-areolar complex, shorten operation duration, and ensure safe and effective surgery in patients.
症状性巨乳症给患者带来了严重的身心负担。乳房缩小术是主要的治疗方法；然而，传统手术可能因损伤主要供血动脉而导致术后乳头乳晕复合体坏死。在本研究中，我们设计并制作了一种创新的三维打印乳房血管模型，为乳房缩小术提供手术指导。收集患者术前计算机断层扫描血管造影扫描数据。然后使用E3D数字医学建模软件（17.06版）对数据进行处理和重建；随后使用立体光刻技术将重建结果打印成个性化模型。由此开发出三维打印乳房血管模型用于个体化术前手术设计。这种个性化模型可用于直观地可视化乳房中主要供血动脉的空间位置，从而为乳房缩小术进行有效的手术规划。因此，三维打印乳房血管模型可以提供个体化的术前设计和患者教育，避免乳头乳晕复合体坏死，缩短手术时间，并确保患者手术的安全有效。
