The thoracodorsal artery perforator (TDAP) flap is a muscle-sparing skin and fat flap that requires precise intramuscular dissection of the thoracodorsal artery perforators in the axillary region. Pre-operative image-based treatment planning is a crucial part of flap design. In this article, we discuss the first-ever reported use of the cinematic volume rendering technique (CVRT) to evaluate the thoracodorsal artery for a TDAP flap phalloplasty in a 49-year-old transgender patient. Cinematic volume rendering technique uses light maps to generate photo-realistic three-dimensional images of the thoracodorsal artery and its perforators. These images aid the surgeon in evaluating optimal perforators and latissimus dorsi muscle involvement for more efficient flap design.
胸背动脉穿支（TDAP）皮瓣是一种保留肌肉的皮肤和脂肪皮瓣，需要在腋窝区域对胸背动脉穿支进行精确的肌内解剖。术前基于图像的治疗计划是皮瓣设计的关键部分。在本文中，我们讨论了首次报道的使用电影体积渲染技术（CVRT）来评估一名49岁变性患者进行TDAP皮瓣阴茎再造术中的胸背动脉。电影体积渲染技术使用光照图生成胸背动脉及其穿支的逼真三维图像。这些图像有助于外科医生评估最佳穿支和背阔肌的受累情况，以进行更有效的皮瓣设计。
