title: Choice of peroneal or dorsalis pedis artery bypass for limb salvage.
abstract: BACKGROUND
  Arterial reconstructions performed for limb salvage have increasingly used peroneal and dorsalis pedis arteries as outflow vessels. However, there have been few published reports comparing the patency and limb salvage of these alternative outflow tracts. In this report, we have examined our experience with the peroneal and dorsalis pedis artery bypasses for limb salvage.
  
  
  METHODS
  During a 19-year period, more than 3,500 infrageniculate reconstructions were performed for limb salvage at our institution. Eight hundred and eighty were performed to the peroneal artery and 291 were performed to the dorsalis pedis. Patients' demographics were similar in both groups. Sixty-three percent of patients were male and 52% were diabetic. All surgeries were performed for patients with critical ischemia. In situ technique was used in 68% of peroneal reconstructions and 66% of dorsalis pedis bypasses, respectively. Translocated veins were used in 28% of bypasses and spliced veins were used in 32%.
  
  
  RESULTS
  Secondary patency rates to the peroneal reconstructions were 89% and 76% at 1 and 5 years, and 88% and 68% for the dorsalis pedis bypasses, respectively. No statistical difference was found. Sixteen (1.8%) of peroneal artery reconstructions were hemodynamic failures and four (1.4%) were hemodynamic failures in the dorsalis pedis group. Wound complications were observed in 19 (2.2%) of the peroneal group and 7 (2.4%) of the dorsalis pedis group. Limb salvage rates for the peroneal artery are 96% and 93% at 1 and 5 years, respectively, and 95% and 87% for the dorsalis pedis reconstructions, respectively.
  
  
  CONCLUSIONS
  This experience indicates that both peroneal and dorsalis pedis artery reconstructions have acceptable patency and limb salvage rates. Selection of one of these two outflow tracts, when a choice exists, may depend on the conduit limitation and the adjacent tissue infection. However, both outflow tracts are durable and hemodynamically effective for limb salvage.
