Treatment Outcomes for Hemangiomas Using Pulsed Dye Laser (595 nm) and Long-Pulse Alexandrite Laser (755 nm)

Abstract

Aim. This study aimed to evaluate the therapeutic effiacy of two laser modalities, namely a 595-nm pulsed dye laser and a 755-nm long-pulse alexandrite laser, in the treatment of hemangiomas in patients with concurrent anemia.Methods. A total of 194 patients diagnosed with infantile hemangiomas, characterized by a thickness ranging from over 2 mm to under 8 mm, were included in this study. The patients were randomly assigned to two groups: the control group received treatment with the 595-nm pulsed dye laser, while the experimental group underwent sequential therapy, beginning with the 755-nm long-pulse alexandrite laser followed by the 595-nm pulsed dye laser.Results. In the control group, the overall treatment effiacy was 36.1 %. In contrast, the experimental group exhibited a signifiantly higher effiacy of 76.3 %. Statistical analysis of the abundance data was conducted using the Chi-square (X2) test, with results deemed statistically signifiant at a signifiance level of P < .05.Conclusion. Sequential therapy, which integrates both the 755-nm pulsed dye laser and the 595-nm pulsed dye laser, demonstrates remarkable effectiveness in treating hemangiomas, particularly in cases complicated by anemia.
