Purpose:
This study aimed to evaluate and analyze the feasibility and the oncological and functional outcomes of limb salvage surgery in extremity soft tissue sarcomas (ESTS) and bone tumors invading vessels.
Materials and Methods:
This single-center retrospective analysis included patients with ESTS encasing or invading major blood vessels that were treated by limb salvage surgery with vascular resection and reconstruction between January 1995 and December 2019. Patients with contiguous involvement of major blood vessels and nerves and patients requiring amputation were excluded from the study.
Results:
A total of 24 vessels (14 arteries and 10 veins) in 14 patients were reconstructed. Ten (71.4%) patients underwent both arterial and venous reconstruction, and four (28.6%) underwent only arterial reconstruction. Reconstruction was performed with a reversed saphenous vein (RSV) graft in 12 patients and with a synthetic graft (SG) in the other 12 patients. At a median follow-up of 27 months, RSV grafts were patent in 10 of 12 (83.3%) vessels and SGs were patent in 6 of 12 (50.0%) vessels (log-rank test, P=0.083). Out of 14 arteries and 10 veins, 11 arteries and 5 veins were patent, respectively. No patient developed local recurrence, and 2 (14.3%) patients developed distant metastases. Limb salvage rate was 13/14 (92.9%). The mean Musculoskeletal Tumor Society score was 83.3%. The 5- and 10-year overall survival rates were 80% and 50%, respectively.
Conclusion
Limb salvage surgery in ESTS with vascular resection and reconstruction is feasible and provides favorable oncological and functional outcomes.

Recurrent parosteal sarcomas with vascular involvement are rare and present unique challenges in their diagnosis and management. We report the case of a 21-year-old woman with parosteal osteosarcoma of the left distal femur, encasing the popliteal vessels. En bloc transarticular resection of the distal femur and popliteal vessels was performed, followed by reconstruction using a modular prosthesis and a saphenous vein autograft for both the artery and vein. On the 1st postoperative day, the patient developed an arterial thrombus requiring reintervention with a jump polytetrafluoroethylene (PTFE) graft. Histopathology confirmed parosteal osteosarcoma.After a disease-free survival of 41 months, the patient experienced local recurrence involving the PTFE graft, leading to graft compression, erosion, and subsequent thrombosis. Despite these complications, limb salvage was possible due to adequate collateral blood supply. This case highlights the feasibility of limb salvage surgery in select cases of parosteal osteosarcoma with vascular involvement.
