The use of free fat pads is effective for repairing pulmonary air leakage clinically. It has been reported that the free pericardial fat pad (FPFP) used to repair the lung remained at the transplanted site in many cases according to images. However, no information is available regarding what type of actual changes these free fat pads with no blood supply undergo. We examined changes in an FPFP that was used to repair pulmonary air leakage in a patient who underwent a surgery for lung cancer 1 year ago. Although the FPFP transplanted to the pleural defect remained without deforming morphologically in this patient 1 year after the first surgery, pathological findings suggested fat necrosis surrounded by fibrous tissue. Our findings suggest that while free fat pads used for pulmonary air leakage repair presumably are not engrafted, they should remain on the lung surface in a thoracolithiasis-like condition.
游离脂肪垫在临床上用于修复肺漏气是有效的。据报道，用于修复肺的游离心包脂肪垫（FPFP）在许多病例中根据影像显示仍留在移植部位。然而，关于这些无血供的游离脂肪垫实际发生何种类型的变化尚无相关信息。我们检查了1年前接受肺癌手术患者用于修复肺漏气的FPFP的变化。尽管在首次手术后1年，移植到胸膜缺损处的FPFP在该患者体内形态上未发生变形，但病理结果提示存在被纤维组织包绕的脂肪坏死。我们的研究结果表明，虽然用于修复肺漏气的游离脂肪垫可能未发生植入，但它们应以类似胸壁结石的状态留在肺表面。
