Case Study of Precise Soft-Tissue Sarcoma Operation Based on Three-Dimensional Modeling Technology

Soft-tissue sarcomas are cancerous growths of mesenchymal tissues, most commonly arising from fat, muscles, and other connective tissues. Due to the fact that these tumors often lie adjacent to nerves and blood vessels, it is difficult to remove them. Traditional surgery is often carried out according to the operator’s discretion and experience of local anatomy; however, the surgery bears the risk of damage to nerves and blood vessels. In cases of postoperative recurrence, the local anatomy is often not clear due to scar formation, and the risk of operation would be greater. This report describes the application of three-dimensional (3D) modeling prior to surgery, which can clearly reveal the tumor tissue and the surrounding important nerves and blood vessels. Considering the relationship between neurovascular and tumor tissue, the intraoperative position, incision, and risk of patients were planned in advance.
