Sternal tumors are rare. The surgical indication in case of metastasis is only justified if the primitive tumor is considered cure and with solitary metastasis. The en-block surgical resection must be based on pre-operative exploration in which a thoracic CAT SCAN has a very important role to determine the extent of the tumor and the anatomico-pathological control of the margin of resection during surgery. The reconstruction using methyl-methacrylate plate is interesting because of its rigid mounting by a moldable substance during surgery, being radiotransparent, inert and well-tolerated by the organism. On high sternal position it contributes to stabilize the scapular belt and assures mediastinal protection. The authors present a case of a partial sternectomy due to metastatic thyroid carcinoma with en-block resection and reconstruction by a methyl-methacrylate moulded plate.
胸骨肿瘤较为罕见。对于发生转移的情况,只有在原发性肿瘤被认为可治愈且为孤立性转移时,手术指征才合理。整块手术切除必须基于术前探查,其中胸部计算机断层扫描(CAT SCAN)在确定肿瘤范围以及手术中切除边缘的解剖病理控制方面起着非常重要的作用。使用甲基丙烯酸甲酯板进行重建很有意义,因为它在手术过程中可通过一种可塑形物质牢固固定,具有射线可透过性、惰性且机体耐受性良好。在胸骨高位时,它有助于稳定肩胛带并确保纵隔得到保护。作者介绍了一例因转移性甲状腺癌行部分胸骨切除术并采用甲基丙烯酸甲酯塑形板进行整块切除和重建的病例。
