- Abstract
- Symmetrical peripheral gangrene (SPG) is rare but devastating complication which is characterized by symmetrical ischemic change of the distal extremities. In this report, we describe our management protocol for SPG, focusing on surgical approaches. Between January 2007 and February 2016, 10 thoracodorsal artery perforator (TDAP) free flaps were performed in 6 patients with SPG. Three patients were male and mean age was 56 (range, 44-69) years. All the patients were in shock. The causes of shock were sepsis in 4 cases, respiratory arrest in 1 case, and hypovolemia in 1 case. Eight transmetatarsal amputations and 2 Lisfranc amputations were performed. Flap sizes ranged from 7 x 11 cm to 25 x 15 cm. There were 3 cases of partial necrosis of the flap: two healed conservatively with dressings and one required skin graft. Three of the patients were later able to walk independently at Functional Ambulation Classification (FAC) level 6, one patient could walk independently on level surfaces at FAC level 5, and 2 could walk independently using walking aids, classified at FAC level 4. The average follow-up period was 18 (range, 6-54) months. In patients with SPG, minimal bone amputation and foot salvage with TDAP flaps were successful. Separate reconstruction of bone and soft tissue had good outcomes.
