Background: 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 operators 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.
Case presentation: 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.
Conclusion: In two operations for recurrent soft-tissue sarcoma of the thigh with complex adjacencies, it was found that 3D models are of great value for preoperative planning and intraoperative navigation. More importantly, these models can improve the success rate of surgery and reduce the operative time.
