Breast reconstruction following the resection of breast cancer with inadequate residual chest-wall tissue may be performed with an implant or a myocutaneous flap, such as the latissimus dorsi or a rectus abdominis. Among a variety of operative procedures, each method has advantages and disadvantages. The insertion of a silicone-bag prosthesis is the easiest method, but the prosthetic implant sometimes has complications, such as unfavorable capsular contracture formation around the implant, rupture, infection, or exposure. We therefore use an extended latissimus dorsi myocutaneous (ELD-MC) flap with some amount of surrounding subcutaneous fat from the lumbar area, and avoid the use of any implant with an MC flap. Also, for the reconstruction and correction of infraclavicular and axillary depression, we use the extended vertical rectus abdominis myocutaneous (EVRAM) flap. This method uses the skin and fat on both sides of the umbilicus as a lenticular flap vascularized by only one of the rectus abdominis muscles. The patients are satisfied with the outcome because symmetry and good breast volume can be obtained. There have been no functional or anatomical defects of the donor area. No abdominal hernia after an EVRAM flap has resulted to date. Both the ELD-MC and EVRAM flaps can be successfully used for cosmetic breast reconstruction after the resection of breast cancer.
对于乳腺癌切除术后胸壁残余组织不足的患者,可采用植入物或肌皮瓣进行乳房重建,如背阔肌瓣或腹直肌瓣。在各种手术方法中,每种方法都有其优缺点。硅胶袋假体植入是最简单的方法,但假体植入有时会出现并发症,如植入物周围形成不良的包膜挛缩、破裂、感染或外露。因此,我们采用带一定量腰部周围皮下脂肪的背阔肌肌皮瓣(ELD-MC瓣),并避免在肌皮瓣中使用任何植入物。此外,为了重建和矫正锁骨下及腋窝凹陷,我们采用延长垂直腹直肌肌皮瓣(EVRAM瓣)。该方法将脐两侧的皮肤和脂肪作为仅由一侧腹直肌供血的双叶皮瓣。患者对手术效果满意,因为可以获得对称性和良好的乳房体积。供区没有功能或解剖缺陷。迄今为止,采用EVRAM瓣后未出现腹部疝。ELD-MC瓣和EVRAM瓣均可成功用于乳腺癌切除术后的乳房美容重建。
