The integration of vascular surgical techniques with oncological surgical protocols in the treatment of soft tissue sarcomas of the limbs

Soft tissue tumors, involving the vascular bundle, require a particular surgical approach: oncological and vascular surgical techniques must be integrated in order to perform a limb-saving surgery with adequate margins. Thirty-six soft tissue sarcomas of the thigh and popliteal region were treated from June 1999 to September 2002. Nineteen cases involving the vascular bundle were analysed and placed in two groups according to imaging and clinical information: Group A, 14 patients, with tumors close to femoral vessels without adventitial infiltration, and Group B, 5 patients, with vascular infiltration. Group A was treated with vascular blunt dissection performing adventitial excision. Group B was treated with vascular 'en-bloc' resection and reconstruction. Imaging and clinical information together with surgical techniques, strategies and complications were analysed in order to plan the surgical approach in neoplastic vascular bundle involvement.
