The Study Of Clinical Effect On Cutaneous Hemangioma

Background Cutaneous hemangioma is the most common benign tumor of childhood. It was categorized as hemangiomas and vascuar malformations. Its pathogenesis is not clear. Most hemangiomas are small and haven't bad effects on people' health. But some of hemangiomas can cause extensive ulceration, bleeding and pain. Some people hope doctor could take nonaggressive treatment, favoring early intervention in an attempt to ameliorate the impact of more severe hemangiomas. Hemangioma patients can be identified in 1.1% to 2.6% of neonates, and their frequency is estimated to be as high as 10% to 12% within the first year of life. They occur in children of all races, but less common in those of African or Asian descent. For unclear reasons, female neonates are more likely to be affected than male neonates with rate of 3 to 5:1. The growth characteristics of hemangiomas are often divided into 3 phases: proliferating, involuting, and involuted.Most of hemangiomas distribute over exposed palces of the body.Most patiens desire to be treated. The orthodox methods such as liquid nitrogen, isotope application, injection of sclerosing agent could result in scar, hypopigmentation and tissue necrosis. Following new types of lasers be operated, cure rate of cutaneous hemangiomas is increasing. These lasers include frequency multiplication Nd.YAG 532nm laser, consecutive Nd.YAG 1064nm laser and pulsed-dye laser. But all treatments have their own advantages and disadvantages. Objective A retrospective review was conducted based on 398 patients with hemangioma treated with 595nm tunable pulsed dye Laser (PDL), and 207 patients treated with liquid nitrogen from 2003.6 to 2005.10 in our hospital. We evaluated...
