Vascular impairment and free tissue transfer in the lower extremity.

Fourteen patients with arteriosclerotic peripheral vascular disease and extensive tissue defects of the lower extremity, underwent microsurgical reconstruction using free tissue ("free flap") transfer. It was possible to provide coverage in ten of these patients. Analysis of this small series showed that only six of these ten patients were able to resume unassisted ambulation. The authors discuss technical aspects of microsurgical reconstruction in this unfavorable group of patients. Analysis of this small series suggest that: (1) inadequate patient motivation, and (2) inability to form granulation tissue in the soft tissue defect, either before or after a vascular reconstructive procedure, are both strong contraindications to microvascular free flap reconstruction in patients with arteriosclerotic peripheral vascular insufficiency of the lower extremity.
