Treatment of neck port-wine stain with intense pulsed light in Chinese population.

AbstractBackground: Studies of lasers or intense pulsed light (IPL) on facial port wine stain (PWS) were frequently reported. Neck PWS was seldom concerned. Objective: This paper was aimed to identify the efficacy and safety of IPL in the treatment of neck PWS in Chinese patients. Methods: Twenty-nine Chinese patients with neck PWS were enrolled to receive IPL therapy for five sessions at an interval of 4- to 5 weeks. The parameters were set as cut-off filters of 560 nm, single pulse with pulse width of 6 ms and fluence of 20–24 J/cm2 or double pulse with pulse width of 4.5–5.0 ms, pulse delay of 15–30 ms, and fluence of 18–25 J/cm2. The efficacy was evaluated using subjective assessment and non-invasive measurement. The adverse effects were recorded. Results: Over 60% patients achieved more than 50% improvement and over 50% participants were very satisfied or satisfied with the treatment. The participants less than 18 years old achieved better efficacy than the participants over 18 years old. The red or ...
