Vascular Lesions and the effect of the vascular lasers
A wide range of vascular lesions occur due to genetic factors, prolonged sun exposure and several medical conditions.
The common lesions include:
Spider nevus: Refers to small capillary dilatation and torsion. Spider nevus is one of the most common skin lesions, specially for those who have fair skin or suffering from certain systemic medical diseases. Despite their pin-point size, they are very resistant to any kind of treatment and require several treatment.
Vascular nevus: they are usually congenital but may not appear until childhood or even later. They are mainly benign and can be managed by a number of lasers, medical treatment or surgical intervention.
Congenital vascular lesions: They are also resistant to any kind of treatment but they may be less invisible after several treatments by the laser or other procedures.
Varicose veins: These lesions are dilatation of the veins rather than the capillaries. They require specific lasers such as ND/YAG and several sessions to disappear.
How does the laser work?
Vascular lesions contain blood, which is the main target or in other word the “ Chromophore” to absorb the laser beam. This is why the laser can damage the vessels without damaging surrounding area.
