Background: Significant advances have been made in using lasers and intense pulse light sources to treat common vascular lesions such as telangiectasias. However, the treatment of leg telangiectasia, specifically, is more challenging because it involves the clearing of smaller veins as well as the larger feeding veins. The latest guidelines recommend use of short wavelength pulse-dyed lasers (PDL) as an option to treat telangiectasia cases that are unresponsive to sclerotherapy. Methods: A 29-year-old white woman presented with persistent telangiectasia, with multiple telangiectasias ranging from 1 cm to 20 cm in size involving the dorsal feet and both ankles and legs, which developed 10 years prior, associated with paresthesia. Test spots were treated with a 585-nm pulsed dye laser with various energy settings, and treatment was performed at 5.5 J/cm2 with spot size 10 mm and 0.5ms pulse duration. Results: Near complete clearance was achieved 1 month after the single treatment without adverse effects. Optical coherence tomography (OCT) imaging demonstrated a reduction of cutaneous blood flow after treatment. Discussion: We report successful treatment despite using settings that were previously reported to lack efficacy. This treatment resulted in considerable improvement in aesthetics and symptomatology. Also, OCT confirmed decreased vascular flow and bulging. Conclusion: Our results suggest there is still much to learn about the use of PDL in treating telangiectasias of the lower extremities, and that the ideal parameters warrant further investigation. Moreover, the novel use of OCT in auxiliary imaging for identification of treatment spots, as well as monitoring response at a microvascular level, holds great potential for wider application.
