Abstract:
Objective To propose the cause and management of necrosis in reversed island flap or distally-pedicled flap. Methods From June 2000 to June 2009, 120 cases with skin and soft tissue defect were repaired using reversed island flap or distally-pedicled flap. In 12 cases the flaps partial necrosis, to analysis the cause of necrosis. Results One hundred and eight cases survived completely in 120 patients,flap necrosis in 12 cases. 3 cases fully necrosis, in which venous disorders cause flap necrosis in 2 cases, arterial blood disorder caused necrosis of flap in 1 case. Partial necrosis in 9 cases, in which dorsal metacarpal artery reversed island flap in 1 case, digital artery reversed island flap in 1 case, posterior tibial artery reversed island flap ankle epithelial branch in 4 cases, medial leg perforating branches of reversed island flap in 1 case, superficial peroneal nerve vascular reversed island flap island flap in 1 case, distally-pedicled based sural neurocutaneous flap in 1 case, after debridement and dressing change subeschar healed in 7 cases, by the other flaps were cut close to rerepair necrotic wounds in 2 cases. Conclusion Blood circulation barrier is the main reason to flap necrosis, improper handling of pedicle is another important reason of flap necrosis,which cannot be ignored.
