“…They also concluded that there was no significant difference in outcomes between patients treated with different wavelengths. 11 Bueno et al 12 published a case series report showing that use of 1470-nm laser is a good method for treating saphenous veins, with results similar to those obtained with 980-nm laser treatment, but with lower energy densities and power.…”

Background Water-specific 1470-nm lasers enable vein ablation at lower energy densities and with fewer side effects because they target interstitial water in the vessel wall. Objectives To determine great saphenous vein (GSV) occlusion rate after thermal ablation with 1470-nm laser using 7W power and to evaluate clinical outcomes and complications. Method Nineteen patients (31 GSVs) underwent thermal ablation. Follow-up duplex scanning, clinical evaluation using the Venous Clinical Severity Score (VCSS), and evaluation of procedure-related complications were performed at 3-5 days after the procedure and at 30 and 180 days. Results Mean patient age was 46 years and 17 of the patients were female (89.47%). Of 31 limbs treated, 2 limbs were clinical class C2, 19 were C3, 9 were C4, and 1 limb was C5 according to the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification. Mean linear endovenous energy density was 33.53 J/cm. The GSV occlusion rate was 93.5% immediately after treatment, 100% at 3-5 days and 100% at 30 days after treatment and 87.1% 180 days after treatment. There was a significant reduction in VCSS at all time points. Conclusions The data from this study support the possibility that the incidence of complications can be reduced without significantly affecting the clinical outcomes, by using lower energy density. However, this appears to be at the cost of reduced efficacy in terms of GSV occlusion rates.

Traditional treatment for great saphenous vein (GSV) insufficiency includes high ligation of the saphenofemoral junction and subsequent stripping of the GSV. However, the considerable morbidity and patient dissatisfaction associated with surgical treatment led to development of alternative techniques and intravenous laser treatment (EVLT) has emerged as a minimally invasive alternative to surgery. Formation of arteriovenous fistulas (AVF) during EVLT is extremely rare. In this study we report a case of AVF between a segment of the lateral accessory saphenous vein and the superficial femoral artery that was identified by ultrasound. Initially, two attempts were made at compression with a linear-array transducer without success, then alternatively surgery was performed without complications, leading to resolution of the AVF. This case report highlights the importance of ultrasound follow-up after EVLT, both for monitoring the effectiveness of the method and for diagnosis and early treatment of its complications.Keywords: varicose veins; laser therapy; ultrasonography; arteriovenous fistula. ResumoO tratamento tradicional da insuficiência da veia safena magna (VSM) inclui a ligadura alta na junção safeno-femoral combinada com a fleboextração. No entanto, a morbidade associada à insatisfação do paciente com esse tratamento tem conduzido ao desenvolvimento de técnicas alternativas, e a termoablação com laser endovenoso (EVLT) tornou-se uma alternativa minimamente invasiva à cirurgia. A formação de fístula arteriovenosa (FAV) durante o EVLT é extremamente rara. Neste estudo, relatamos um caso de identificação ecográfica de FAV entre um segmento da veia safena acessória lateral e a artéria femoral superficial. Optou-se inicialmente pela realização de duas tentativas de compressão com transdutor linear, sem sucesso, e alternativamente o procedimento cirúrgico foi realizado sem intercorrência e com resolução da FAV. Esse relato de caso evidencia a importância do seguimento de vigilância ecográfica após o EVLT tanto para o controle da efetividade do método como para o diagnóstico e tratamento precoce de suas complicações.Palavras-chave: varizes; terapia a laser; ultrassonografia; fístula arteriovenosa.
