Use of custom made 3-dimensional printed surgical guide for manubrio-sternal resection of solitary breast cancer metastasis: case report.

A 44-year-old lady with solitary 4.4-cm metastasis to the manubrium from a previously resected invasive ductal carcinoma of the left breast underwent manubrio-sternal resection. We describe our unique approach of using 3-dimensional (3D)-computed tomography (CT) image segmentation planning for reconstructing desirable resection boundaries, design of ideal superficial and deep surgical resection guides, and followed by 3D printing of guides using autoclavable thermoplastic for use during surgery. The surgical guides over the ribs and sternum rapidly and accurately define resection lines intraoperatively, achieve good surgical margins, and could reduce resection and reconstruction related morbidity for performing complex surgical resection of the chest wall. The patient was discharged 2 weeks postoperatively and remained free from local recurrence on CT scan 1-year after resection. 2020 AME Case Reports. All rights reserved.
