Abstract

Background “Subfascial void reconstruction” in ischial pressure sores (IPSs) goes a long way in the amelioration of the common complications like persistent drainage, infection, wound dehiscence, and late recurrence. No locoregional flaps suffice this requirement. So we have designed a chimeric pedicled flap based on the inferior gluteal vessel axis (IGVA) perforators with two tissue components: (1) Pacman-style fasciocutaneous flap on a perforator and (2) gluteus maximus muscle (inferior portion) on another independent perforator.

Aim and Methods After confirming the feasibility of novel design of chimeric pedicled IGVA perforator flap with cadaver study, we embarked on the clinical study with this chimeric flap. In this prospective cohort study, the study and the control existed in the same patient so that the biological factors affecting the wound healing would be the same.

Results Twenty-one patients were included whose mean age was 39 years. Late recurrence occurred in one patient (4.8%) of chimeric flap while the control group (who had undergone conventional reconstruction) had recurrence in 11 patients (52.4%). On assessment with overall institutional score, grade A was observed in 18 patients of the chimeric IGVA flap group (p < 0.045), and in only 3 patients of the control group.

Conclusions This anatomically construed flap, a new addendum in the armamentarium of reconstruction of IPSs, with its potential to congruently fill the ischiogluteal subfascial void may provide a lasting solution for preventing recurrences.
