Laser assisted sclerotherapy method for treating varicose veins

摘要

The present invention relates to a laser device including a laser source for generating a pulsed laser radiation having a wavelength of from 1400 to 2300 nm and at least one optical fibre for conveying the generated pulsed laser radiation, for use in a method for treating varicose veins, the laser device being for use in a pretreatment step of a target vein segment thereby causing a substantial diameter reduction of the target vein segment, the pre-treated target vein segment being subsequently subjected to a sclerosing treatment thereby causing occlusion of the vein. The sclerosing agent is preferably a foam sclerosing agent. The above treatment is particularly effective also for larger veins, especially veins exceeding 10 mm of diameter, without causing major discomfort to the patients, and which has a very limited risk of side effects, such as those deriving from the injection of relatively large amounts of sclerosing agent or from damages to the vessel endothelium.
