Efficacy of the 595 nm pulsed dye laser in the treatment of hemangiomas in Vietnamese patients

Hemangiomas are common benign vascular tumors that often present in childhood. The 595 nm pulsed dye laser (PDL) is now being widely used to treat vascular skin lesions. This case series was performed to review the therapeutic efficacy and safety of PDL in the treatment of hemangiomas among Vietnamese patients. A total of 43 Vietnamese patients (79.1% females), mean age was 8.83 years old (2 months - 54 years old), with a clinical diagnosis of hemangioma, were treated with the PDL over 2 years. Treatments were performed every 4 weeks. Hemangioma lesions that occur on the head and the neck are seen in 65.1%, 67.4% of superficial, and 32.6% of mixed hemangioma subtypes. The mean treatment is 5.3 times. Excellent-good results were achieved in 86.1%, average results in 11.6%. No permanent side effects during the treatments were observed. Treatment of hemangiomas using the 595 nm PDL is an effective and safe method in the skin types of Vietnamese patients. The effect does require several treatment sessions.
