Abstract
Congenital capillary malformation, or port,vine stains (PWS), have been tre ated with the pulsed dye laser since the late 1980s, Some studies have show n better results when the malformation has been located on the lateral face , forehead, neck, trunk or shoulder and inferior results, with more treatme nts required, when it is located on the central face area, dermatome V2 or the extremities. The purpose of this study was to determine the depth of th e lesion in various locations. A total of 55 patients with untreated PWS we re investigated with a high-resolution 20 MHz ultrasound system, The mean m aximum depth of all PWS that were measurable (45 out of 55) was 1.00 mm (+/ -0.50 SD), with a range of 0.2-3.7 mm, Lesions located on the forehead (1.2 6 +/- 0.44 mm) and on the medial face (1.23+/-0.65 mm), were deeper than le sions on the trunk and extremities. PWS involving areas that respond poorly to treatment were on average 0.14 mm deeper than PWS involving areas that responded well, The depth of the PWS, as determined with high-resolution ul trasound, seems to correlate only to some degree with the response to pulse d dye laser treatment, Since this treatment, with its superficial penetrati on, cannot reach the deeper vessels of a PWS, skin ultrasound could be a go od complement in the prognostic investigation as well as for planning treat ment.
