[Potential and limitations of dye laser therapy for capillary malformations].

Capillary malformations (port-wine stains) are observed in less than 1 % of neonates and may occur coincidentally with other vascular and nonvascular malformations. Two thirds of lesions occur in the head and neck area and may have important cosmetic and psychological implications for the patients. Treatment with flashlamp-pumped pulsed dye lasers is still the therapy of choice for capillary malformations and can be applied to infants. If the laser device is used appropriately, the rate of persistent side effects is low. Although laser treatment achieves good clearance in the majority of patients with capillary malformations, complete clearance is rare. New therapeutic options are thus urgently required.
