Infantile Hemangioma: Clinical Characteristics and Efficacy of Treatment with the Long‐Pulsed 1,064‐nm Neodymium‐Doped Yttrium Aluminum Garnet Laser in 794 Chinese Patients

Objective This study aimed to evaluate the clinical characteristics of infantile hemangiomas ( IH s) and the safety and efficacy of the long‐pulse 1,064‐nm neodymium‐doped yttrium aluminum garnet (Nd: YAG ) laser for definitive treatment of IH s in 794 Chinese patients. Methods Infants with hemangiomas who had received long‐pulse 1,064‐nm Nd: YAG laser treatment in our department in the last 5 years were recruited. Demographic and clinical characteristics were recorded and outcomes of long‐pulse 1,064‐nm Nd: YAG laser treatment were assessed. Statistical analyses were performed to identify factors that affected the efficacy of treatment. Results The efficacy of long‐pulse 1,064‐nm Nd: YAG laser for the treatment of IH s in all patients in our study was 87.57%. Efficacy did not depend on sex or the location of the lesion. Older age and superficial hemangioma were the primary factors contributing to greater efficacy of long‐pulse 1,064‐nm Nd: YAG laser treatment for IH s. The most common side effects were pigment changes, skin atrophy, and wrinkled redundant skin, which usually resolved spontaneously within 1 to 3 years. Conclusions Long‐pulse 1,064‐nm Nd: YAG laser is a safe and efficacious treatment for IH s.
