Paper Abstract

The use of pulsed dye laser for the treatment of Capillary Vascular Malformations (CVMs) only leads to complete clearing of the abnormality in a minority of cases. In order to examine the characteristics of a CVM, which determine its response to laser treatment, we have used videomicroscopy. By using a videomicroscope to determine the vessels diameters within a CVM in-vivo it is hoped that treatment parameters can be chosen which would be most appropriate to achieve the best response. To increase the clarity of our images and reduce reflection we carried out a videomicrographic examination using both normal white light and green filtered light on 24 sites on 18 patients. For the deeply placed reticular vessels we found no difference between the results obtained with the two techniques. However, for the superficial papillary vessels we found a statistically significant (p < 0.01) increase in the recordings taken with the green filtered lens. We attribute this difference to the reduction in reflection seen with the green filter. We have also developed a depth measuring videomicroscope, which allows the calculation of vessel depth as well as vessel diameter.
