La escleroterapia (inyecci\u00f3n qu\u00edmica) se utiliza generalmente para las venas afluentes visibles y superficiales o las ara\u00f1as vasculares despu\u00e9s de haber cerrado el tronco principal con l\u00e1ser. Son complementarios, no se excluyen mutuamente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">P2: \u00bfEl l\u00e1ser de 1470 nm s\u00f3lo sirve para las venas?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aunque 1470 nm es el \u201cespecialista en venas\u201d, su alta absorci\u00f3n de agua tambi\u00e9n lo hace excelente para otras cirug\u00edas de tejidos blandos, como la PLDD (descompresi\u00f3n discal percut\u00e1nea con l\u00e1ser) en la columna vertebral o las intervenciones de ORL, ya que vaporiza el tejido con un sangrado m\u00ednimo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">P3: \u00bfCu\u00e1l es el riesgo de TVP con <a href=\"https:\/\/fotonmedix.com\/es\/categoria\/producto\/\"   title=\"Productos\"  data-wpil-monitor-id=\"2327\">tratamiento l\u00e1ser<\/a>?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El riesgo es extremadamente bajo (&lt;1%) cuando se siguen los protocolos adecuados. Para mitigarlo, se anima a los pacientes a caminar inmediatamente despu\u00e9s del procedimiento para estimular el flujo sangu\u00edneo en las venas profundas, y la punta del l\u00e1ser se mantiene a una distancia segura de la uni\u00f3n venosa profunda.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">P4: \u00bfPuede volver a crecer la vena tratada?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No. El segmento de vena tratado queda fibrosado de forma permanente y es absorbido por el organismo. Sin embargo, dado que la enfermedad venosa es cr\u00f3nica, con el tiempo pueden volverse incompetentes nuevas venas (recidiva), lo que requiere una evaluaci\u00f3n futura.<\/p>","protected":false},"excerpt":{"rendered":"<p>In the trajectory of vascular surgery, few innovations have displaced a century-old standard of care as rapidly as Endovenous Laser Ablation (EVLT).
