Therapeutic effect of high-frequency ultrasound-assisted dye laser on hemangioma and its influence on serum HIF-1α in patients.

Background: To analyze the therapeutic effect of high-frequency ultrasound (HFU)-assisted dye laser on hemangioma patients and changes in serum hypoxia-inducible factor-1α (HIF-1α).

Methods: A total of 20 patients diagnosed with hemangioma in our hospital from January 2013 to March 2018 were selected, including 12 males and eight females. All patients were treated with HFU-assisted dye laser. The site and type of hemangioma and age distribution of patients were collected, and changes in data and area of hemangioma and serum HIF-1α before and after treatment were analyzed.

Results: The vascular condition of hemangioma in all patients was significantly improved at 7, 14, and 30 days after treatment. Gray-scale ultrasound displayed that the tumor area was reduced by more than 50%. After treatment, the serum HIF-1α level declined obviously after treatment compared with that before treatment, showing a statistically significant difference (P < 0.05).

Conclusion: HFU-assisted dye laser can effectively reduce the tumor area, decrease the serum HIF-1α level, and improve the prognosis in the treatment of hemangioma.
