METHOD FOR THE TREATMENT OF PETECHIAL-ARACHNOID AND LINEAR FORMS OF CAPILLARY ANGIODYSPLASIA OF THE SKIN IN CHILDREN Russian patent published in 2023 - IPC A61B18/20 

FIELD: medicine; dentistry.

SUBSTANCE: in the treatment of petechial-arachnoid form of capillary angiodysplasia by transcutaneous selective photodestruction (TSF), laser radiation with a wavelength of 525 nm is used, and TSF is carried out by placing the end of the manipulator in contact and perpendicular to the skin surface above the central petechial vascular element. When the central vascular element lies at a depth of 0.5 to 1.0 mm from the skin surface, laser radiation is used with a power of 2.0 W, a pulse duration of 1.6 ms, a pulse repetition rate of 50 Hz, a laser spot diameter of 1 mm, and an exposure time of 2 .0 sec. When the central vascular element lies at a depth of 0.5 to 1.0 mm from the skin surface, laser radiation is used with a power of 3.0 W, a pulse duration of 30 ms, a pulse repetition rate of 50 Hz, a laser spot diameter of 1 mm and an exposure time of 2.5 sec. In the treatment of a linear form of capillary angiodysplasia, TSF is carried out using laser radiation with a wavelength of 525 nm, moving the end of the manipulator located perpendicularly and in contact with the skin surface along the entire length of the expanded vascular element. When the diameter of the expanded capillary vascular element is less than 0.5 mm, TSF is carried out with laser radiation with a power of 2.0 W, a pulse duration of 1.6 ms, a pulse repetition rate of 50 Hz, a laser spot diameter of 1 mm, and a scanning speed of 1.0 cm per second. When the diameter of the expanded capillary vascular element is from 0.5 to 1.0 mm, TSF is carried out with laser radiation with a power of 3.0 W, a pulse duration of 30 ms, a pulse repetition rate of 50 Hz, a laser spot diameter of 1 mm, with a scanning speed of 0.5 cm per sec.

EFFECT: method provides a radical controlled destructive effect on the subepithelial vascular structures of capillary angiodysplasia of the skin, without damaging the surrounding tissue structures and epithelium, and contributes to the achievement of a good clinical and aesthetic result of treatment.
