Vascular Lesion Technique and Endpoints
• Ensure that the handpiece is in full contact with the skin during treatment.
- Pay particular attention when treating rounded/bony areas.
- Precool the skin to help prevent epidermal damage.
- Ensure that each pulse receives both pre- and postcooling.
- The length of pre- and postcooling required will vary according to size, color, and
depth of vessel.
- Larger, darker vessels require longer pre- and postcooling.
• Do not stack pulses or double pulse.
- For smaller vessels, place treatment pulses adjacent or slightly spaced (avoiding
overlap).
- For larger vessels, leave a half spot size to full spot size space between pulses.
• Endpoints will vary based on type, size, color, volume, pressure, and location of the vein.
- Common endpoints are color change, vein disappearance, and constriction.
- If the clinical endpoint is not reached, shorten the pulse duration. If the clinical
endpoint is still not reached, then increase the fluence.
- The endpoint may not be evident or may be very subtle when treating larger
reticular leg veins.
