Keloid Treatment Using Plasma Exeresis: A Pilot Trial Study.

Keloid scars and hypertrophic scars are more commonly seen after surgeries, suture placements, or other skin damages. Scars can be treated using a variety of methods, including topical compounds, surgery, and lasers. The aim of this study is to evaluate the effects of plasma exeresis on the treatment of keloid scars. This experimental study was conducted on patients with keloid scars, defined as a treatment-resistant subtype of scars with extension beyond the primary skin defect and cauliflower appearance, in different parts of the body. The patients were treated with 2-to-3-session plasma exeresis. Scars were examined based on the Vancouver scar scale (VSS) before and 5 months after the treatment. A total number of 24 scars were enrolled in this study. The number of patients was 16. There was a decrease in the mean thickness of keloids from 2.20 to 0.54 (=0.000). The mean pigmentation and pliability scores decreased from 1.54 and 2.16 to 0.375 and 0.541, respectively (=0.001, 000). There was a significant reduction in the keloid scar vascularity score from 1.666 to 0.541 (=0.000). There was a decrease from 0.708 to 0.00 (=0.004) in the mean itchiness score. After the intervention, the mean pain score was 0.000, compared to 0.7500 before the intervention (=0.003). There was a decrease in the total score from 8.958 to 2.000 (=0.000). The plasma exeresis procedure is effective in destroying small keloid scars. Furthermore, results in less itching and pain, as well as no significant complications or recurrences.
