No results posted yet for this study

Summary

This prospective, non-randomized study aims to evaluate the efficacy and tolerability of treating port-wine stains (capillary malformations) using pulsed dye laser (PDL), potassium titanyl phosphate (KTP) laser, or a sequential combination of both. Each participant will receive all three treatments on different areas of the lesion. The primary outcome is improvement measured using the Investigator Global Assessment (IGA) scale. Secondary outcomes include pain (VAS), local adverse events, and patient satisfaction.

Conditions

  • Port-Wine Stains (Capillary Malformations)

Interventions

DEVICE

Pulsed dye laser (PDL)

Treatment with a pulsed dye laser (PDL) at 595 nm using the VBeam Prima® system (Candela Medical). Parameters: 10 mm spot size, 7-9 J/cm² fluence, 0.5-3 ms pulse duration. Cryogen spray cooling is applied. No anesthesia is used. This intervention will be applied to one of the three defined regions of each participant's port-wine stain.

DEVICE

Potassium titanyl phosphate (KTP) laser

Treatment with a KTP laser at 532 nm using the DermaV® system (Lutronic Medical Systems). Parameters: 10 mm spot size, 8-11 J/cm² fluence, 10 ms pulse duration. Cryogen spray cooling is applied. No anesthesia is used. This intervention will be applied to a second anatomically comparable region of the port-wine stain.

DEVICE

Sequential KTP + PDL laser treatment

Sequential treatment of the same region with two lasers: first with KTP (532 nm, DermaV® system), then with PDL (595 nm, VBeam Prima® system). Each laser will be applied using its standard parameters: KTP (10 mm spot, 8-11 J/cm², 10 ms), followed by PDL (10 mm spot, 7-9 J/cm², 0.5-3 ms). Cryogen spray cooling is used before each pass. No anesthesia is applied. This treatment is administered to a third region of the port-wine stain.
