BACKGROUND: Port-wine stains (PWS) are relatively common and often cause cosmetic and psychological concerns. The pulsed dye laser is currently the treatment of choice for PWS.
OBJECTIVE: To assess the effectiveness of the pulsed sequential dual wavelength 595 and 1064 nm laser as first-line treatment for PWS and to identify prognostic factors for treatment outcome in a retrospective series of 17 consecutive previously untreated patients.
METHODS: The response to treatment was evaluated 2 months after treatment utilizing comparative photographs and a standard physician global assessment (PGA) grading system. Furthermore, measurement of the normalized erythema index (NEI) reduction (ΔNEI%) was carried out using an image analysis system. The subjective improvement was assessed using a patient's satisfaction questionnaire. Multiple linear regression models were finally used to identify factors associated with ΔNEI% and patients' satisfaction.
RESULTS: Seventeen patients, with PWS, including 12 children were included. The average PGA assessment was 2.5 ± 1.3 corresponding to an amelioration of 50% with a high intraclass correlation coefficient among the experts. The before-after NEI showed a statistically significant mean reduction of 3.5 ± 2.6 units, corresponding to a relative reduction of 31%. Questionnaires showed that the satisfaction was very good with an average score of 6.1 points on a scale ranging from -10 to 10 points. Multiple regression analysis revealed that location in the frontotemporal area was associated with a significant reduction in ΔNEI% (38.4%; 95% CI 4.3, 72.6). Presence of PWS on the neck was associated with a lower patient satisfaction (-3.7 points; 95% CI -6.5, -0.9). There were no significant side-effects, except for transient discomfort and purpura.
CONCLUSIONS: Based on the results obtained in the largest reported series so far, the pulsed sequential dual wavelength 595 and 1064 nm laser represents an effective and safe first-line therapeutic option for the treatment of PWS.
