The pedicled internal pudendal artery perforator flap for ischial pressure sore reconstruction: technique and long-term outcome of a cohort study

The ischial region is the site most affected by pressure sores and has the highest recurrence and complication rates compared to other affected sites. We developed a practical and safe pedicled flap for reconstruction of ischial pressure sores based on the rich available perforators from the internal pudendal artery and the surplus of skin at the infragluteal fold.
