The lumbar artery perforator (LAP) flap is a relatively new procedure that can be utilized to manage lumbosacral defects in addition to reconstructing distal body parts as well, such as breast reconstruction. This fasciocutaneous flap is designed based on the LAPs small arteries that emerge from the lumbar arteries then move superficially piercing overlying tissues to perforate the lumbar fascia and supply the skin and subcutaneous tissue; However, anatomical and clinical studies regarding the LAP flap and its perforators are sparse in the literature, and the results are even contradicting. This article will discuss the LAP flap, the anatomy of its perforators, and the clinical aspects about its usage. In addition, we explore its preoperative imaging evaluation, and deliver a guide on image reporting and radiological data that will benefit the surgeon most during the procedure.
腰动脉穿支皮瓣（LAP）是一种相对较新的手术方法，可用于治疗腰骶部缺损，也可用于重建远端身体部位，如乳房重建。这种筋膜皮瓣是根据从腰动脉发出的 LAP 小动脉设计的，这些小动脉向上移动，穿过覆盖的组织，穿透腰筋膜，为皮肤和皮下组织提供血液供应；然而，关于 LAP 皮瓣及其穿支的解剖学和临床研究在文献中很少，结果甚至相互矛盾。本文将讨论 LAP 皮瓣、其穿支的解剖结构以及其临床应用方面。此外，我们还探讨了其术前影像学评估，并提供了一份关于图像报告和影像学数据的指南，这将在手术过程中对医生最有帮助。
