Abstract

Ultrasound can be easily introduced into the soft tissues of the body, and its intensity can be concentrated in one point when the rays of a broad transducer are focused. In order to achieve this, a concave transducer can be used or the beam of a planar transducer can be bundled using an ultrasonic lens. A high enough intensity to heat the focal point to over 45 degree C must be used. No morphological damage has been found below 42 degree C. If the focus is positioned at the intimal wall of the vein to be treated, high-energy ultrasound heats up the tissue and produces damage. A similar reaction as in sclerotherapy is expected to occur after the intima is damaged.
