PURPOSE The aim of this study was to determine the possible predictors of primary arteriovenous fistula (AVF) failure and examine the impact of a preoperative evaluation on AVF outcomes. METHODS A total of 539 patients who underwent assessment for a suitable site for AVF creation by physical examination alone or additional duplex ultrasound were included in this study. Demographics, patient c...

Duplex ultrasound has long been the method of choice in the diagnosis and evaluation of deep venous thrombosis and carotid artery stenosis and in monitoring lower extremity bypasses. In recent years, innovative procedures and technology have fostered new applications for duplex ultrasound, such as detection of in-stent stenosis and endoleaks, intraoperative evaluation of in situ vein bypasses a...

OBJECTIVE Endothermal ablation (ETA) of the great saphenous vein (GSV) is associated with a small but definite risk of endothermal heat-induced thrombosis (EHIT) extending into the common femoral vein. Follow-up duplex ultrasound imaging to detect EHIT after ETA is considered standard of care, although the exact timing of duplex ultrasound imaging to detect EHIT after ETA remains unclear. We hy...

BACKGROUND The aim of this study is to describe point-of-care ultrasound and Color flow Duplex Doppler characteristics of penetrating and blunt trauma-related vascular injuries of the limbs and neck. METHODS Penetrating and blunt trauma-related vascular injuries such as vein disruption, intimal flap, deep vein thrombosis, arterial dissection, pseudoaneurysm, and arteriovenous fistulae are dis...

OBJECTIVE To compare duplex ultrasound and computed tomography (CT) angiography in terms of their performance in detecting endoleaks, as well as in determining the diameter of the aneurysm sac, in the postoperative follow-up of endovascular abdominal aortic aneurysm repair. MATERIALS AND METHODS This was a prospective study involving 30 patients who had undergone endovascular repair of infrar...

Duplex ultrasound is widely used to detect vascular dysfunction after kidney transplantation. We describe musical murmurs found in renal allografts. A 29-year-old man with an increase in serum creatinine 1 month after cadaveric kidney transplantation was referred for duplex ultrasound to exclude perfusion dysfunction. Renal arterial and venous circulation was normal. However, during Doppler spe...

BACKGROUND Non-recurrent inferior laryngeal nerve (NRILN) is usually discovered during thyroid surgery. It is often associated with vascular abnormalities that can be detected with magnetic resonance imaging (MRI) or duplex ultrasound scan. The aim of this study was to compare the diagnostic sensitivity of ultrasonography with MRI to identify the vascular abnormalities associated to NRILN. PA...

Introduction Duplex ultrasound has become the first line of investigation for the autogenous arterio-venous hemodialysis fistula (aAVF). In recent work published by our group, we showed that duplex ultrasound was as accurate as fistulography in the assessment of fistula stenoses. The emergence of duplex ultrasound as the primary tool for examination of the aAVF is the result of better technolog...

BACKGROUND Abernethy malformation is a rare congenital vascular abnormality in which the portal vein bypasses the liver and drains directly into the inferior vena cava. Diagnosis is complex and requires good quality imaging methods to identify details in systemic and portal circulation in order to establish diagnostic confirmation and treatment strategy. In this study we highlight the significa...
