DALLAS – Laser treatment of port wine stains in infancy is both safe and effective, with no incidence of scarring or pigmentary changes, according to results from a single-center analysis.
“Early intervention allows for treatment without general anesthesia, with faster and more complete clearance than what has been reported for treatments begun at older ages,” Hana Jeon, MD, said at the annual conference of the American Society for Laser Medicine and Surgery.
A recent Food and Drug Administration Drug Safety Communication warned that “repeated or lengthy used of general anesthetic and sedation drugs during surgeries or procedures in children younger than 3 years or in pregnant women during their third trimester may affect the development of children’s brains.” Dr. Jeon, a dermatologist in private practice in New York, noted that the FDA warning “places a greater importance on the already controversial topic of when to initiate port wine stain [PWS] treatments in pediatric patients, which requires repeated treatments and are often performed with general anesthesia. Without treatment, these lesions tend to get larger and thicker with time. Starting the treatment during infancy has the potential to limit the use of general anesthesia and to facilitate clearing.”
In what she said is the largest retrospective study of its kind to date, Dr. Jeon and her associates evaluated the success and safety of treating PWSs with a pulsed dye laser at the age of 1 year or younger in the office setting without general anesthesia. The patients received their first PWS treatment at their center during 2000-2017. They reviewed the charts of 197 patients to extract relevant data, including demographic information, age at the time of procedure, and treatment dates. The data cutoff was at 1 year following the initial treatment. Four physicians independently reviewed before and after photos and used the visual analogue scale to grade them.
The pulsed dye laser with dynamic cooling spray was used to minimize patient discomfort. No topical, local, or general anesthesia was used. Patients were immobilized by ancillary staff with parents present in most cases. Ocular shields were placed to allow treatment of periocular lesions.
Of the 197 patients, 63% were female, 90.1% had Fitzpatrick skin types I-III, 8.1% had type IV skin, and the rest had type V-VI skin. Most of the lesions were facial (75.6%), and 41.1% had periocular involvement. The average lesion size was 61 cm2.
The treatment settings for the pulsed dye laser were a 10-12 mm spot size delivered at a fluence of 6.5-9 J/cm2 in a pulse duration of 0.45-1.5 milliseconds. The average age at the time of first treatment was 3.4 months (range, 5-355 days), and the average number of treatments was 9.8 (range, 2-23). Most of the patients (116) were aged 0-3 months at the time of first treatment, followed by 51 aged 3-6 months, 19 aged 6-9 months, and 11 aged 9-12 months.
According to the averaged scores on the visual analogue scale assigned by physicians, 27.4% showed a 100% clearance, 39.1% showed 76%-99% improvement, 15.1% showed 51%-75% improvement, 10.7% showed 26%-50% improvement, and 7.7% showed 0%-25% improvement. No scarring or pigmentary changes were observed.
An analysis of dermatomal distribution revealed that the presence of a V1 lesion was a statistically significant predictor of a higher clearance rate, while the presence of a V3 lesion was a statistically significant predictor of a low clearance rate. “Regardless of where the lesion was, all patients did well,” she said.
Given the small proportion of patients who received their first treatment between the ages of 6 and 12 months of age, Dr. Jeon said that “further studies would be needed to elucidate whether earlier intervention helps to achieve better results.”*
Advantages of early treatment, she said, include the ability to “treat lesions before they get larger and thicker, which also decreases the risk of spontaneous bleeding. Thinner skin allows for better penetration of the laser beam, and we can also avoid using general anesthesia. Psychologically, if we’re able to clear these lesions, it can result in improved quality of life and self-esteem; not just for the patient but for the family as well.”
Dr. Jeon acknowledged certain limitations of the study, including its retrospective design, variable follow-up times, and non-standardization of photographs.
She reported having no financial disclosures.
