Alogenic platelet lysate in necrosis of the torn piece

摘要

The use of allogenic platelet lysate opens another therapeutic possibility in orthopedics. Its use is presented in a 40 year-old patient with previous history of bronchial asthma and treated with steroids who, as a result a fall, suffered an extensive avulsive wound in her right foot of approximately 11 cm with skin laceration and necrosis of the torn piece, with vertex distal and proximal base that only took skin, with another torn piece of similar bodering and a diameter of approximatety 6 cm. A toilette and necrectomy of the cyanotic edge was made, mainly in the vertexes. Confrontation stitches were taken and an extreme fragility of the skin was observed when carrying this procedure. Treatment with antibiotics was started and after 48 hours necrosis of two third of the skin of the torn piece was observed which was not removed for ten days. After removal local therapy with alogenic platelet lysate was applied on alternate days. Improving of granulation was observed, but not in the surrounding skin lesion. Then, a perilessional infiltration with allogenic platelet lysate was made which improved the lesion appearance and its healing in a period of only 7 days.
