The authors describe the techniques that use the principles of fat grafting to allow them to successfully graft megavolumes (250-ml range) of autologous fat into breasts. The Brava external volume expansion device preoperatively increases the volume and vascularity of the recipient site. Low-pressure liposuction and minimal centrifugation are used to gently extract and purify the adipose tissue with minimal trauma. Even and diffuse reinjection of the fat increases graft-to-recipient interface and reduces interstitial fluid pressure. Postoperative Brava use protects the graft and acts as a three-dimensional immobilizing splint. By adhering to these techniques, we have been able to graft megavolumes of fat into the breasts of over 1000 patients and obtain substantial long-term volume retention.
作者描述了一些技术，这些技术利用脂肪移植的原理，使他们能够成功地将 250 毫升至 500 毫升之间的大容量自体脂肪移植到乳房中。Brava 外部容量扩张装置在术前增加了受区的体积和血管化程度。使用低压吸脂和最小程度的离心作用，轻柔地提取和纯化脂肪组织，最大限度地减少创伤。均匀且弥散的脂肪再注射增加了移植物与受区的界面，并降低了间质液压力。术后使用 Brava 保护移植物，并起到三维固定夹板的作用。通过坚持这些技术，我们已经能够将大容量的脂肪移植到 1000 多名患者的乳房中，并获得了可观的长期体积保留。
