Resumo

A terapia das varizes dos membros inferiores tem sido realizada classicamente por cirurgia e escleroterapia, sendo a escolha basicamente dependente do seu calibre. Entretanto, a associação de técnicas costuma ser uma necessidade para a obtenção de bons resultados. Os meios físicos surgiram no final da década de 50 e continuaram a progredir com grande diversidade quanto à natureza, princípio físico e efeitos. A complexidade tecnológica é bastante variável. Eletrocoagulação, laser, luz intensa pulsada, crioesclerose endovascular, ultra-som e microondas são meios físicos potencialmente viáveis para esta condição. Entretanto, com algumas exceções, pouco tem sido descrito fora dos centros de pesquisa, e a participação como opção terapêutica ainda necessita de uma melhor definição do papel. O artigo tem como objetivo descrever os métodos físicos empregados ou em estudo para a terapia de varizes.

Abstract

The therapy of varicose veins of the lower limbs has classically been carried out with surgery and sclerotherapy, depending on vessel diameter. However, the association of techniques is frequently necessary to assure a good result. The use of physical procedures to promote occlusion of varicose veins was firstly attempted in the 1950s. There are different physical principles and effects based on different technological levels. Electrocoagulation, laser, intense pulsed light, endovascular cryosclerosis, ultrasound and microwave are physical sources potentially useful for this condition. Unfortunately, these technologies are not wide available outside research centers, with a few exceptions, and their role in clinical practice still needs to be defined. This paper aims to describe the physical procedures currently used or potentially useful for the therapy of varicose veins.
