Duplex ultrasound incorporates 2-dimensional gray-scale ultrasound to provide an image of arterial structures and pulse-wave Doppler to sample velocities of blood flow at a specific location within the artery lumen. Although ankle-brachial BP index (ABI) is a simple and reliable test for PAD screening, its sensitivity has been suggested to decrease among dialysis patients. of this study is to calculate agreement between the two diagnostic tests of PAD, ankle brachial index [ABI] and ultrasound duplexes scanning [UDS] and to evaluate the results of these tests against symptoms of patients we designed this study on PAD patients. 1. PAD is the accumulation of plaques that can narrow or block the arterial blood supply, leading to claudication, ischemia, or necrosis. See All. Photos. A tear in the layers of a blood vessel wall. Because of its ability to determine and measure occlusions, it can be instrumental in planning angioplasty or surgery [13–16]. It’s often used to detect peripheral artery disease (PAD). Research suggests that point-of-care duplex ultrasound (PAD-scan) is cost-effective for the detection of PAD in patients with diabetes. After endovascular intervention, duplex ultrasound-derived mean PSVs fell within or near established reference ranges for patients without peripheral arterial disease. Peripheral artery disease (PAD) typically refers to atherosclerotic narrowing and/or occlusion of all arterial disease other than coronary arteries and the aorta (carotid and vertebral arteries, coeliac and mesenteric arteries, renal arteries and upper and lower limb arteries) (figure 1).

It also may be used before or after a procedure to restore blood flow to determine if the procedure was a success. The reliability, portability, and range of studies that can be performed with duplex ultrasound make it indispensable … Vein mapping to evaluate veins prior to surgery. 1,2. Swollen, twisted veins that can be seen under the skin’s surface. The vascular sonographer can map disease in lower-extremity segments with great accuracy, though duplex scanning is more time-consuming than other lower-extremity arterial studies. Duplex ultrasonography was done with Philips duplex ultrasound machine bandwidth frequency transducer with a range of 5–13 MHz for the lower limb artery and 3.5 MHz probe for the infrarenal aorta and iliac vessels.

This study aimed to assess the diagnostic accuracy of duplex sonography (DUS) compared with that of computed tomography angiography (CTA) in detecting occlusion and stenosis in peripheral arterial disease (PAD) in candidate patients for endovascular revascularization with intraprocedural digital subtraction angiography (DSA). Renal duplex ultrasound examines the kidneys and their blood vessels. Duplex ultrasound followed by MRA, where clinically appropriate and if needed, offers the most accurate, safe and cost-effective imaging strategy for people with PAD. Low-frequency (2 or 3 MHz) transducers are best for evaluating the aorta and iliac … Vascular duplex ultrasound studies of dialysis access sites, such as arteriovenous fistulas (AV fistulas) or AV grafts.
