Objective：To discuss the treatment for hemangiomas and vascular malformations. Methods: A retrospective study was conducted on 381 patients with hemangiomas and vascular malformations (January of 1998 to June of 2006). The patients consisted of 167 males and 214 females,with an age range from 1 year to 78 years (median age 16 years). According to the biological classification system introduced by Mulliken in 1982,98 patients had hemangiomas,38 had capillary malformations,203 had venous malformations,27 had arteriovenous malformations and 15 had lymphatic malformations. In all patients with hemangiomas,71 patients were treated with intralesional steroids,20 patients underwent surgical excision,7 patients were carefully monitored by doctors. In 38 patients with capillary malformations,27 underwent sclerosant,others were subjected to laser therapy or surgery. In 203 patients with venous malformation,136 received sclerotherapy,21 received surgical excision,and 11 underwent sclerotherapy conjunction plus surgical excision. Twenty-seven patients with arteriovenous malformations received sclerotherapy,interventional therapy,or sclerotherapy conjunction plus surgical excision. Fifteen patients with lymphatic malformations received sclerotherapy conjunction plus surgical excision. Results: All patients were followed-up for 0.5-6 years. Follow-up result showed that 199 patients were cured,125 were greatly improved,and 46 were partly improved; 10 patients showed no obvious improvement; and 1 patient died. Conclusion: Correct diagnosis and the classification,along with correct treatment strategy, are the keys to increase the treatment outcome and decrease complication of patients with hemangiomas and vascular malformations.
