Pilot Study to Evaluate the Effect of Multiple Passes on Port Wine Stain Treatments With the Cutera Excel V™ Laser.

Paused · Not applicable

Conditions studied: Port-Wine Stain

In brief

Two limitations of single pulse, laser treatment of port-wine stains (PWS) are: (i) hemorrhage and purpura which may lead to post-treatment pigmentation and (ii) the necessity for repeated treatment sessions. In contrast, multiple pulses induce summation of irreversible, thermal injury from a series of lower-peak temperature heating cycles and may therefore reduce mechanical injury while preserving the selectivity of photothermal injury. Ideally, hemorrhage could be prevented and the efficiency of vessel closure could be greater. A clinical and histological pilot study of 10 adults with either facial or non-facial PWS is therefore proposed here.

You may not qualify if…

Participation in a clinical trial of another drug, or device administered to the treatment area, within 3 months prior to enrollment or during the study.
Any type of prior cosmetic or port wine stain treatment to the target area within 3 months of study participation.
Suffering from significant skin conditions in the treated areas or inflammatory skin conditions, including but not limited to, open lacerations or abrasions, hidradenitis, rash, infection , or dermatitis of the treatment area prior to treatment (duration of resolution as per the Investigator's discretion).
