Dye laser treatment for hemorrhagic vascular lesions

Abstract

Background and aims: It is generally thought that bleeding from a hemangioma is difficult to stop. With development of the long pulse dye laser (LPDL), it has become possible to treat hemangioma with a large blood vessel diameter. Thus, it is effective in treating infantile hemangioma and pyogenic granuloma. Materials and methods: Five patients who visited our hospital from July 2015 to July 2017 due to hemorrhagic hemangioma were treated using a flash lamp excitation pulse dye laser with parameters of 7 mm spot size, 3 msec pulse width, fluence 12-14J/cm2, DCD 30 msec, and delay 30 msec. Results: The bleeding not only stopped, but the raised lesion was flattened in all cases. Conclusions: LPDL is effective for both infantile hemangioma and pyogenic granuloma. It not only stops bleeding, but also treats the vascular lesions.
