Limb salvage in lower-extremity sarcomas and technical details about vascular reconstruction.
Vascular surgery may allow limb salvage when a sarcoma of the lower limb involves the main vascular bundle. We present our experience and describe the techniques which have been employed for such surgery. From October 1995 to April 1999, vascular surgery procedures were employed in seven patients with sarcomas of the thigh: two complete subadventitia dissections of the main vascular trunks, four artery replacements (two polytetrafluoroethylene [PTFE] grafts and two autologous saphenous grafts), and five venous reconstructions (all with autogenous saphenous graft: three substitutions; two distal transpositions with one external rigid support at the anastomosis). Clinical and instrumental (sonogram, computed tomography [CT] scan, echodoppler) follow-up was carried out at 3, 6, and then every 12 months after surgery (mean, 25 months; range, 6-53 months). Operative mortality and morbidity were nil. All the grafts were patent (one arterial thrombosis was successfully treated on the first postoperative day). The functional result was good in six patients and fair in one. Two patients died, 24 and 13 months after surgery, with disseminated disease, but had no local recurrence. Five patients are alive and disease-free. Vascular techniques allow limb salvage with en-bloc resection of sarcomas of the thigh involving the main vessels. Venous reconstructions are indicated after removal of both the superficial and deep femoral veins. We suggest limiting the number of anastomoses (two transpositions in our series) and using external rigid support in those patients with a small saphenous vein graft (one patient in our series).
