Background: Surgical removal of the tumor remains the only 1 radical treatment of patients with soft tissue sarcomas of the extremities. However, the parameters of total and disease-free survival after this type of treatment cannot be considered satisfactory. Currently the active search and introduction into clinical practice of additional impact methods that can improve the immediate and long-term results of treatment of such patients is being conducted. Aim: To evaluate the risk of the wound process complications after surgical treatment of soft tissue sarcomas using endovascular embolization and cryosurgery. Methods: We have assessed the quantity and quality of postoperative complications of wound process in 199 patients with soft tissue sarcomas and their recurrences. The study group consisted of 53 patients, who underwent radical surgery with selective preoperative endovascular embolization and intraoperative cryosurgery. The control group consisted of 146 patients who had radical surgery without any additional methods. Preoperative embolization and cryosurgery on the wound bed after tumor removal was used to prevent local recurrence of soft tissue sarcomas. Preoperative angiography with selective embolization of vessels feeding the tumor was performed 1-1.5 hours before the main surgical treatment. Cryosurgery was carried out by the method of “Olympic rings” with 3 minutes duration. The temperature of exposure was −186°C. In the course of cryosurgery we adhere to the principle of “quick freezing - an independent slow thawing”. All postoperative wounds tightly sutured with silicone drains by Redon, if necessary. Results: Complications of wound healing have been diagnosed in 15 (28.3%) patients of the main group and in 34 (23.3%) control group patients. Inflammatory-suppurative complications were observed in the remaining 8 (15.1%) patients of the main group and in 18 (12.3%) control group patients ( P > 0.05). Long lymphorrhea was observed in 6 (11.3%) patients of the main group and 11 (7.5%) control group patients. Bleeding in the postoperative period was observed in 1 (1.9%) case of main group patients and in 5 (3.4%) cases of control group. Conclusion: The additional using of selective preoperative endovascular embolization and cryosurgery is safe and does not worsen immediate results of surgical treatment of soft tissue sarcomas.
