A. the common femoral artery (cfa) is lateral to the femoral vein (fv) on a transverse scan at the inguinal crease. note that the size of the color box is as small as possible. b. the superficial femoral artery (sfa) and the deep femoral artery (dfa) make a shape like mickey mouse’s ears, and the fv forms mickey mouse’s face.

Femoral Vein Doppler Ultrasound Normal Vs Abnormal Image Appeara Noninvasive spectral doppler waveform assessment is a principal diagnostic tool used in the diagnosis of arterial and venous disease states. with 200 million people affected by peripheral artery disease worldwide 1,2 and >600 000 hospital admissions yearly for venous thromboembolic disease in the united states, 3,4 establishment and adoption of nomenclature for spectral doppler waveform. Arteriovenous fistulas (avfs) are anomalous connections between the arterial and venous system that divert blood from the normal anatomic capillary beds. fistulas may occur anywhere in the body, be single or multiple, and be congenital or acquired (eg, trauma) ( table 1 ). acquired avf of the lower extremity is by far the most common avf. Arteriovenous fistulas have a number of etiologies. they can be iatrogenic in origin, particularly with percutaneous procedures, when a needle passes through both an artery and vein. they may also occur when an aneurysmal artery ruptures into an adjacent vein (as can happen with coronary artery aneurysms ). the most common arteriovenous fistula. Arteriovenous fistulas (avfs) are abnormal connections between an artery and a vein (see image. diagram of arteriovenous fistula).[1] in certain contexts, these may also be referred to as arteriovenous malformations.[2] avfs can exist almost anywhere in the body, depending on the etiology. these can be divided into 2 groups: acquired or congenital. acquired fistulas can be further subdivided.

Native arteriovenous fistula (avf) is the vascular access of choice for hemodialysis patients. compared with grafts and central venous catheters, avfs last longer and are associated with fewer complications. the widespread use of the doppler ultrasound (dus) has increased the number of patients who are eligible for avf by facilitating the. Volume flow of >1000 ml min in the brachial artery and a pav diameter of ≥3.5 mm are predictive of a well functioning fistula. intimal thickening at the anastomosis can be measured on ultrasound and may be another useful parameter in the assessment of a failing fistula. these parameters could be used to exclude a significant inflow stenosis.
