Com o avanço tecnológico, os procedimentos cirúrgicos tendem a se tornar cada vez mais seguros e menos invasivos. A cirurgia minimamente invasiva, feita por incisões cada vez menores, diminui a agressão ao organismo. Cirurgias antes realizadas sob anestesia geral, em que os pacientes eram abertos para a retirada de órgãos doentes, foram substituidas por técnicas que permitem o tratamento com o paciente acordado, ou apenas sedado.
O Laser vascular foi desenvolvido para termocoagular as células endoteliais da veia, causando fechamento do vaso doente. A lesão térmica causa trombose controlada do vaso e posteriormente ocorre sua reabsorção. Outro mecanismo de ação é a contração do colágeno por coagulação proteica, que ocorre por volta de 50˚C.
A cirurgia de varizes a laser pode não ser adequada a todos os casos. Portanto consulte seu cirurgião vascular para saber mais a respeito.
Vantagens da a cirurgia de varizes a Laser:
menor trauma operatório,
melhor evolução,
excelente eficácia (>96%) a curto prazo,
procedimento mais rápido,
menor incidência de complicações,
menor gravidade das complicações,
retorno às atividades em até 2 ou 3 dias
Recomenda-se para um resultado mais duradouro a utilização do laser em associação à fleboextração de pequenos vasos (microcirurgia dos vazinhos).:
Veja no vídeo abaixo o método de funcionamento do laser, que tem a propriedade de ser absorvido apenas pelo tecido e pigmento adequado:

O procedimento é realizado com anestesia local e sedação, em regime de hospital dia. É feita pequena punção em veia doente da perna e inserido fibra ótica, através da qual o laser é emitido. Esse laser aumenta a temperatura local, fechando a veia doente.
Indicação:
Insuficiência venosa e doença venosa superficial a partir de CEAP 2 (CEAP 2,3,4,5,6). Em alguns casos muito especificos pode ser necessário em CEAP 1 com desejo estético.
Resultado/Objetivo:
O objetivo do tratamento venoso com laser é o fechamento das veias doentes principais, evitando que o sangue reflua pela falha das válvulas.
Preparação:
É necessário jejum de 8 horas. A realização de exames pré operatórios permite o cálculo do risco cirúrgico.
