Proliferative Vascular Lesions

VivoSight measures depth, diameter and density of vessels in vascular lesions

Angiographic optical coherence tomography imaging of hemangiomas and port wine birthmarks. Lasers in surgery and medicine. 2018 Sep;50(7):718-26. Dr Jill Waibel - Miami Laser Dermatology Institute

Kelly and Waibel et. al. [1] used VivoSight and showed that vascular lesions have a broad range of vessel diameters and depths.

Successful therapy is based on the principles of Selective Photothermolysis (Anderson and Parrish, Science 1983) which requires:

  • WAVELENGHT that is preferentially absorbed by the desired target structure
  • Laser pulse width that is less than or equal to the thermal relaxation time of the vessel targeted as determined by VESSEL DIAMETER
  • Sufficient radiant exposure, FLUENCE, to reach a damaging temperature in the target. VESSEL DEPTH can impact fluence requirements.

The wide variety of challenging vascular lesions requires better data on the underlying vascular pathology for better treatment

VivoSight vascular measurements inform treatment parameters for therapy that is targeted to lesion characteristics.

Clinical Application Areas:

Port Wine Stains, Hemangiomas and Rosacea show a wide variety of vascular metrics, requiring a more individual treatment approach:
