Coverage of pressure sores with free flaps

Introduction. The coverage of recurrent pressure sores with unstable scar in the surrounding tissue is still an unsolved problem in the literature. Local and regional transfer of tissue often does not meet the requirements of the tissue deficit. Especially in recurrent pressure sores,the adjacent skin has already been consumed due to multiple surgeries. As a good alternative,the microsurgical transfer of flaps offers viable tissue to cover even large pressure sores. Methods. We performed a total of six free flaps in five patients who suffered from intractable pressure sores in the hip region. The age of the patients was between 41 and 63 years. The defect size varied between 6x6 cm and 25x30 cm. Two combined myocutaneous scapula-latissimus dorsi, two myocutaneous latissimus dorsi, one anteromedial thigh, and one rectus femoris flap were used to cover the defects. Results. The average follow-up time was 29 months. Flaps provided stable coverage in four of five patients at 12-month follow-up. There was one subtotal flap necrosis that was subsequently treated with split-thickness skin grafting. Conclusion. In this series of five patients with six free flaps, we were able to show that-the microsurgical transfer of tissue is a valuable option in the treatment of difficult pressure sores. Even in older and debilitated patients, this method is a good alternative to conventional local flaps.
