Objective the aim of this study was to assess the results of mechanochemical endovenous ablation either in the primary or recurrent saphenous vein insufficiency, including only patients with veno-venous shunt type III. Methods retrospective analysis of a prospective study of patients with symptomatic chronic venous insufficiency who underwent ClariVein® technique. A total of 134 saphenous veins were included between August 2017 and August 2018. Follow-up was performed by Duplex ultrasound at 1, 6 and 12 months. Primary endpoints were technical and anatomical success. Secondary endpoints were the need for further treatment of varicose collateral veins by sclerotherapy, outcomes regarding recurrent insufficiency and clinical success. Results A total of 111 great saphenous veins and 23 small saphenous veins were treated with a technical success of 95.6%. The overall anatomical success rates at 1, 6 and 12 month were 96.2%, 88.8% and 84.4%, respectively, without differences between primary and recurrent insufficiency. Deferred sclerotherapy over varicose collaterals was carried out in 28% of the patients with anatomical success. Clinical improvement was achieved in 87.3%. Conclusions MOCA technique has proven to be an effective technique, although additional treatment over varicose collaterals could be necessary in up to one-third. Atrophy of the saphenous vein and the lack of persistent varicose collateral veins during follow-up seem to be indicators of successful therapy.
El uso de Terapia de Presión Negativa como técnica de cura de heridas está cada vez más extendido, y tanto sus indicaciones como ámbitos de utilización siguen creciendo. Desde hace años también se emplea con frecuencia en la Unidad de Cirugía Vascular del Hospital Central de Asturias. El presente estudio ha tenido como objetivos analizar las características y etiología de las lesiones tratadas con Terapia de Presión Negativa, así como los criterios de aplicación de la técnica, los resultados y las complicaciones.Se ha realizado un estudio descriptivo y retrospectivo de heridas tratadas con Terapia de Presión Negativa en nuestra Unidad durante un periodo de 18 meses en el que se incluyeron 51 casos. Se creó una base de datos ACCES donde se registraron los datos relacionados con las variables de estudio recogidos de las historias clínicas. Para el análisis estadístico se ha llevado a cabo un análisis descriptivo, con cálculo de frecuencias absolutas y relativas para las variables cualitativas, y media con desviación estándar para las variables cuantitativas.Esta terapia ha demostrado ser un tratamiento seguro (11,76 % de complicaciones leves) y efectivo (5,88% heridas curaron y 76,47% mejoraron) en nuestros pacientes. Hemos distanciado las curas una media de 5,48 días y se ha podido completar el tratamiento a nivel ambulatorio en el 62,74% de casos.
