Role of Platelet Rich Plasma in Enhancing Graft Take in Chronic Venous Ulcers

Fourteen patients had bilateral lower limb ulcers, and 6 of them had single large ulcers as follows; Fourteen patients with chronic venous ulcers (12 of which had bilateral ulcers, 2 had single large ulcers) Four patients, each with a single chronic post-traumatic ulcer Two patients with bilateral chronic lymphatic ulcers.

After detailed history, physical examination and investigations (such as duplex),

• Each patient with bilateral ulcers included in the study (14 patients) received treatment A on one ulcer and treatment B on the other ulcer.
• In case of patients with single large ulcers (6 patients), treatment A was done on one half of the ulcer and treatment B on the other half of the ulcer (done in ulcers with an area greater than 10 x 10 cms).
• Treatment A included pre-operative intra-lesional PRP injections in 1-week intervals for 3 times, followed by intra-operative intra-lesional injection of PRP prior to meshed graft placement. PRP was injected into the ulcer bed and ulcer edges using a sterile syringe.

Treatment B included only placement of meshed graft, with no PRP treatment.

• Pre-operative preparation: Ulcers were prepared by proper dressings and followed up until acquiring a clean bed. Debridement was done as needed to obtain clean base ready for graft placement.
• PRP preparation:
