background: atherosclerosis of the peripheral arteries occurs in 12% of individuals at 65 years of age or older. at least 28% of these patients suffer from coronary heart diseases and 10% of them are afflicted with cerebrovascular diseases. to calculate the agreement between two diagnostic tests for peripheral arterial disease (pad), namely ankle brachial index (abi) and ultrasound duplex scann...

Duplex ultrasound is used in many radiology departments as the first line of investigation for symptomatic deep venous thrombosis. Before changing the practice of our department from venography to duplex ultrasonography, we wanted to assess our ability to identify deep venous thrombosis on ultrasound. Thirty-eight patients were investigated for suspected deep venous thrombosis by venography and...

Hypokalemia FIGURE 3-16 Comparison of duplex ultrasound with arteriography. A total of 102 consecutive patients with both duplex ultrasound scanning of the renal arteries and renal arteriography were prospectively studied. All patients in this study had difficult-to-control hypertension, unexplained azotemia, or associated peripheral vascular disease, giving them a high pretest likelihood of re...

INTRODUCTION Duplex ultrasound facilitates bedside diagnosis and hence timely patient care. Its uptake has been hampered by training and accreditation issues. We have developed an assessment tool for Duplex arterial stenosis measurement for both simulator and patient based training. METHODS A novel assessment tool: duplex ultrasound assessment of technical skills was developed. A modified dup...

background: carotid ultrasound appears to be useful in the assessment of cardiovascular risk. in this study, we have assessed the carotid intima-media thickness (cimt) in a group of individuals without a history of cardiovascular events. methods: a sample of 431subjects (189 [43.9%] males and 242 [56.1%] females) was obtained from an urban population using a stratifi ed-cluster method in mashha...

OBJECTIVE To verify the diagnostic efficiency of venous duplex ultrasound and lymphangioscintigraphy (LAS) in establishing the cause of leg edema and to clarify the pathology of these leg edemas. MATERIALS AND METHODS Between April 2009, and March 2010, 62 patients with leg edema of unknown origin were referred to the Edema Clinic of the Yamaguchi University Graduate School of Medicine. All p...

HYPOTHESIS Incidental thyroid masses identified during carotid duplex ultrasonography may represent clinically significant lesions. DESIGN AND SETTING Retrospective review of a prospective database in a tertiary care referral center. PATIENTS A total of 2004 consecutive patients from January, 2000, through January, 2002, undergoing carotid duplex ultrasonography. INTERVENTIONS After bilat...

Background Patients with post-thrombotic syndrome due to chronic venous obstruction and resistant to conservative management can benefit from endovenous revascularization. The current study investigated the usefulness of duplex ultrasound in monitoring the stent changes over the time. Method All duplex ultrasound images of treated patients were reviewed retrospectively. The stent diameter and a...

Late complications following endovascular aneurysm repair indicate the need for long-term surveillance. Clinical trials involving endoluminal stent grafts have typically used computed tomography angiography as the main imaging modality for surveillance. However, computed tomography angiography exposes the patient to higher levels of ionizing radiation, nephrotoxic agents, and increased cost com...
