Clover-Style Fasciocutaneous Perforator Flap for Reconstruction of Massive Sacral Pressure Sores

As a common complication of the long-term bedridden patients, pressure sore is a great challenge for surgeons. The purpose of this study was to explore the surgical method of using a clover-style fasciocutaneous perforator flap raised on the buttocks for the treatment of massive sacral pressure sores and report the clinical outcomes.

The study included 15 patients from January 2015 to June 2017 with an average age of 52.87 years (range, 32-73 years). The size of the sacral pressure sores ranged from 10 cm × 13 cm to 18 cm × 20 cm. The defects were reconstructed using a fasciocutaneous perforator flap raised on the buttocks after debridement and vacuum sealing drainage treatment for 1 to 2 weeks. All the donor areas were sutured directly.

All flaps survived completely; 13 patients achieved healing by primary intention, and the other 2 patients achieved healing by secondary intention. At the mean follow-up period of 20.8 months (range, 12-46 months), the appearance of the flap, including its texture and color, in all patients was satisfactory. No patients had deep infection, necrosis, or shrinkage of the flap during the follow-up period. One patient had a recurrent bedsore during the 2-year follow-up.

The clover-style fasciocutaneous perforator flap is ideal for the reconstruction of massive sacral pressure sores because it is a relatively simple procedure and results in good appearance and function, few complications, and a low recurrence rate.
