ABSTRACT

Abstract Objectives Patients undergoing surgery for locally advanced lung cancer involving the chest wall require anatomical lung with extensive en-bloc chest wall resection and appropriate reconstruction. In this proof-of-concept study, we aimed to produce personalized three-dimensional (3D)-printed chest wall prosthesis for a patient undergoing chest wall resection and reconstruction using clinically obtained computed tomography (CT) data. Methods Preoperative CT scans of three patients undergoing chest wall resection were analyzed and the areas of resection segmented. This was then used to produce a 3D print of the chest wall and a silicone mold was created from the model. This mold was sterilized and used to produce methyl methacrylate prostheses which were then implanted into the patients. Results Three patients had their chest wall reconstructed using this technique to produce a patient specific prosthesis. There were no early complications or deaths. Conclusions It is possible to use 3D printing to produce a patient specific chest wall reconstruction for patients undergoing chest wall resection for malignancy that is cost-effective. This chest wall is thought to provide stability in the form of prosthetic ribs as well compliance in the form of an expanded polytetrafluoroethylene patch. Further research is required to measure chest wall compliance during the respiratory cycle and long-term follow-up from this method.
