“…More invasive imaging exams and surgical or endovascular treatment should be reserved for patients who become symptomatic. 8 In the case described here -an asymptomatic patient whose AVF was found during a routine sonographic follow-up examination -it is believed that the cause of AVF formation was probably linked to a iatrogenic injury during the perivenous tumescence procedure. Initially, two attempts were made at compression with a linear transducer, separated by a 1-week interval, but they were unsuccessful, probably because of the high throughput of the AVF.…”

“…These patients were initially managed conservatively and two of them enjoyed spontaneous resolution in 12 weeks, while the third's fistula remained patent, but its peak systolic velocity reduced over 18-months of follow-up. 7 In a review published in 2011, Rudarakanchana et al 8 reported 11 cases described in the literature of AVF after venous thermal ablation, the majority after EVLT. The symptoms displayed by patients after formation of the AVF varied greatly.…”

“…Both puncture and infiltration of the tumescence liquid should be guided with ultrasound. 8 For the majority of EVLT-related AVFs, the literature does not appear to support surgical treatment. Clinical observation is preferred instead.…”

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.

Two cases of arteriovenous fistula formation between the external iliac vessels following endovenous laser therapy

Minimally invasive treatment of varicose veins is becoming increasingly popular with both patients and physicians. Endovenous laser therapy has been shown to be safe and effective but the rare complication of iatrogenic creation of arteriovenous fistulas has been described. One case of fistulation between the external iliac artery and vein has been published. We report two further cases and describe their management.

“…AVFs can lead to partial patency of ablated segments with pulsatile flow on duplex ultrasound. AVFs between the proximal SSV and the sural artery or between the superficial external epigastric artery and proximal GSV have been described (44,45).…”

Venous incompetence in the lower extremity is a common clinical problem. Basic understanding of venous anatomy, pathophysiologic mechanisms of venous reflux is essential for choosing the appropriate treatment strategy. The complex interplay of venous pressure, abdominal pressure, venous valvular function and gravitational force determine the venous incompetence. This review is intended to provide a succinct review of the pathophysiology of venous incompetence and the current role of imaging in its management.
