The treatment of port wine stains and telangiactatic leg veins have a promising future through an indocyanine green-augmented diode laser treatment. This unique treatment involves using water-soluble indocyanine green fluorescent dye, which is typically used in medical diagnostics to pinpoint cardiac output, liver and blood flow and for ophthalmic angiography.
As a treatment for port wine stains the indocyanine green-augmented diode laser treatment was compared with the typical flashlamp-pumped pulsed dye laser treatment in patients with port wine stains. Following a single treatment, researchers rated the ICG+DL as slightly better than the FPDL treatment. While patients rarely see a complete eradication of the port wine stain, because the small blood vessels are resistant to laser irradiation, the study suggested that the ICG treatment, coupled with laser treatments, might overcome the stains’ resistance to treatment. The results were deemed “intriguing” by researchers who also noted there was no “epidermal damage at 1 week and that complete remodeling of dermal tissue had occurred by 3 months.”
Under a separate study, telangiectatic leg veins, which can rarely be completely eradicated, were studied. Two dozen women in the study found more than a partial clearing of the veins. The treatment was undertaken in two separate steps with the ICG being used initially with a follow up of the diode laser pulses. The treatment showed clearing with no significant or persistent side effects. The results provided hope for those who suffer either of these potentially disfiguring conditions.
