Successful reconstruction of the chest wall frame with superelastic nickel-titanium 3D modules in a patient with multiple locally recurrent leiomyosarcoma

Abstract

Introduction. An additional or the only way to treat tumors of the chest wall is often a surgical method, which inevitably results in a post-resection defect. Reconstruction of extensive chest wall defects remains an unsolved problem for surgeons around the world.The study objective – to present the long-term oncological and functional results of treatment of a patient with multiple locally recurrent leiomyosarcoma after reconstruction of an extensive post-resection chest wall defect using superelastic 3D frame modules made of titanium nickelide. Reconstruction of the chest wall with 3D modules after extensive block resection showed the possibility of not only restoring the anatomy in the area of the post-resection defect, but also maintaining the biomechanics of breathing in the postoperative period.Clinical observation. This study presents a clinical case of extensive resection and successful one-stage reconstruction of the chest wall skeleton with 3D superelastic titanium nickelide modules in a patient with recurrent leiomyoma with locally recurrent leiomyosarcoma.Results. The superelastic modules did not limit the width of the resection during the operation and ensured long-term stability of the position of the reinforcing elements of the artificial framework. Control examinations showed no tumor recurrence after 12 months and maintaining patient performance.Conclusion. The effectiveness of the proposed reconstruction expands the possibilities of treating patients with tumors of the chest wall.
