title: Long term follow-up of intralesional laser photocoagulation (ILP) for hemangioma patients.
abstract: OBJECTIVE
  Hemangiomas remain a challenge for patients and plastic surgeons. Promising results have been reported using intralesional photocoagulation (ILP) for treatment. The objective of our study is to review the long term results of a large series of hemangiomas in patients treated by ILP. Materials (Subjects) and Methods: A retrospective review of 684 hemangiomas in patients were treated by ILP with an Nd:YAG (neodymium-yttrium-aluminium-garnet) (1064 nm) laser over a period of 10 years (January 1996-January 2005). Patients' ages ranged from one month to 11 years 5 months (mean, 1 year 10 months). The patient group consisted of 474 females and 210 males.
  
  
  RESULTS
  Patients were treated with an Nd:YAG laser delivered through a 600 m optical fiber. Laser power was set at 7 to 15 watts (W) and delivered with pulse duration of 7 to 15 seconds (s). The results showed 603 (88.6%) patients had more than 50% reduction of the volume in hemangiomas at 3 months after one treatment; and 663 (96.9%) patients had more than 50% reduction of the volume at 3 months after two treatments. Patients who had continuous ILP achieved excellent results.
  
  
  CONCLUSIONS
  Postoperative complications have been related to photocoagulation that has been delivered too extensively or superficially, with resultant ulceration, infection, bleeding, and scarring. These complications can be avoided if this potential for harm is kept in mind.
