Dermatologists have for many years treated vascular lesions by a variety of modalities
including cryosurgery, electrotherapy, dermabrasion and radiation.
It has been hypothesized that simultaneous delivery of these two wavelengths may provide
safer, and in some cases more effective, vascular lesion removal.
The Tandem laser is capable of emitting multiple cryogen spurts intermittently with multiple
532/1064 nm laser pulses.This mode may reduce malformed blood vessels with a low incidence
of long-term side effects.
The researcher can determine the blanching of vascular lesions after Tandem laser with
multiple 532/1064 nm laser pulses treatment.
The researcher will select one to four test sites spots for laser treatment. will be
Different laser parameters can be used for each test site. The research will evaluate of the
test sites at 6-12 weeks for bruising and blanching. Parameters of the test area with the
greatest degree of blanching without adverse effects will be utilized for further treatment.
If no test area is determined to have blanching without adverse effects, further test sites
may be performed.
- Adult age 18 years and older
- Diagnosis of vascular lesion
- Age <18
- History of cutaneous photosensitivity
- Any therapy to the proposed treatment sites within the previous two months
- Current participation in any other investigational drug or device evaluation
