Insights
Flashlamp pulsed dye laser (FPDL) treatment for port-wine stains (PWS) is a safe and effective method. While temporary pigmentary changes and cutaneous depressions can occur, they typically resolve spontaneously, making FPDL a secure technique.
Area of Science:
- Dermatology
- Laser Therapy
- Vascular Malformations
Background:
- Port-wine stains (PWS) are congenital vascular malformations affecting 0.3%-0.5% of newborns.
- PWS can lead to significant physical and psychological complications.
- Flashlamp pulsed dye laser (FPDL) is a primary treatment modality for PWS.
Purpose of the Study:
- To evaluate the frequency and nature of cutaneous side-effects and complications associated with FPDL treatment in PWS patients.
- To assess the safety profile of FPDL therapy for port-wine stains.
Main Methods:
- Eighty-nine patients with PWS were treated with FPDL at 3-month intervals.
- Treatment involved overlapping pulses with fluences of 6.0-9.0 J/cm2.
- Physicians evaluated patients, and side-effects/complications were systematically recorded.
Main Results:
- Pigmentary changes, including hyperpigmentation (16.8%) and hypopigmentation (2.4%), were the most common complications.
- Cutaneous depressions occurred in 2.2% of patients.
- Transient pustulosis and one hypertrophic scar were reported; all resolved spontaneously.
Conclusions:
- FPDL treatment for PWS is associated with a low incidence of complications.
- The majority of observed side-effects are transient and resolve completely.
- FPDL is confirmed as a secure and effective technique for managing port-wine stains.
Background:
Port-wine stains (PWS) are a congenital, progressive ectasia of the superficial cutaneous vascular plexus that occur in 0.3%-0.5% of children at birth. They should be considered a disease with physical and psychologic complications. Treatment with the flashlamp pulsed dye laser (FPOL) has proven to be effective. Because treatment results in selective vascular injury, the risk of complications is minimal. The purpose of this study was to determine the cutaneous side-effects and complications and their frequency in patients with PWS treated with the FPDL. Eighty-nine patients who had been treated with the FPDL for PWS were included in this study.
Methods:
Patients were treated at 3-month intervals using slightly overlapping pulses with fluences of 6.0-9.0 J/cm2. Treating physicians were responsible for evaluating the patients. All patients were reviewed and side-effects and complications were recorded.
Results:
Pigmentary changes were the most frequently observed complications. Hyper- and hypopigmentation appeared in 16.8% and 2.4% of patients, respectively. Cutaneous depressions occurred in 2.2% of patients. One patient developed a hypertrophic scar, and another patient presented with transient cutaneous pustulosis. All these changes usually resolved spontaneously and completely in a few months.
Conclusions:
Most of the side-effects and complications produced by the FPDL are usually transitory, and it is essentially a very secure technique.
