A 15-year experience with combined vascular reconstruction and free flap transfer for limb-salvage.

OBJECTIVES

To evaluate the results and complications of combined simultaneous arterial re-vascularisation and free flap transfer in patients with critical limb ischaemia and large soft-tissue defects that would otherwise have required major amputation.

DESIGN

Retrospective analysis of all combined procedures performed between 1993 and 2007 with regard to complications and outcome.

MATERIALS AND METHODS

Seventy-eight procedures were performed in 76 patients with a mean age of 60 years (range: 18-80 years). The majority had diabetes (70.5%). Follow-up was obtained from hospital charts and telephone contacts with patients or GPs.

RESULTS

The limb-salvage rate was 93% after 1 year, 80% after 3 years and 71% after 5 years. Perioperative complications occurred in 50% of the patients; six out of 78 (7.7%) arterial reconstructions and 13 out of 78 (16.7%) flaps had to be revised during the early postoperative period. However, most flaps could be saved by a secondary procedure resulting in an early failure (amputation) rate of 6%. In-hospital mortality was 3.8%. End-stage renal disease was the only factor predicting limb loss. In total, 65% of the patients survived and were able to walk on their reconstructed limb at 1-year follow-up. Combined survival and limb-salvage rates were 85%, 66% and 51% after 1, 3 and 5 years.

CONCLUSIONS

Combined arterial re-vascularisation and free flap transfer can be performed safely with acceptable morbidity and mortality and should be considered for every mobile patient with large soft-tissue deficit (>10cm(2)) without end-stage renal disease prior to major amputation.
