Objective:
To investigate the closing method of wound after removal of the traditional pedicled abdominal flap.
Methods:
According to the design, the pedicled abdominal flaps were cut and lifted, and then the incision were extended from both sides on base of the flap to anterior superior iliac spine, respectively. After separating on superficial fascia, two flaps were obtained. The wound of donor site was closed completely by these two pedicled flaps. Twelve patients with skin defects on hands or forearms were treated using the reformed method of traditional pedicled abdominal flap.
Results:
All of the 12 reformed pedicled abdominal flaps survived, and only one had local necrosis on the distal part of the abdominal flap, about 1.5 cm x 2.0 cm.
Conclusion:
This new design could provide a good method to close the abdominal wound after removal of pedicled abdominal flap.
