The Role of Duplex Ultrasound in Assessing AVF Maturation
Annals of Vascular Surgery, 2021Arteriovenous fistulas (AVFs) are favored for hemodialysis (HD) access. However, in many instances, AVFs fail to mature. We examined the utility of postoperative color duplex ultrasound (CDU) in assessing AVF maturation and determining the need for balloon-assisted maturation (BAM).A total of 633 patients underwent AVF creation at a single institution ...

Duplex Doppler penile ultrasound
Current Sexual Health Reports, 2006Duplex Doppler penile ultrasound (DDPU) is a useful, minimally invasive method for evaluating penile hemodynamics in patients with erectile dysfunction. The measurement of peak flow velocity, end-diastolic flow, and resistance index is helpful in assessment of the penile vascular status, especially in patients who do not respond to oral therapy ...

Duplex Doppler Systems in Obstetric Ultrasound
Radiologic Clinics of North America, 1990Doppler ultrasound applications in normal and complicated pregnancies are presented in this article. Anatomy and pathophysiology of fetal placental blood flow are described. Potential pitfalls in the evaluation of fetal placental blood flow are explored. Doppler flow velocity waveform analysis combined with other clinical and physiologic information is

Mesenteric and renal arterial duplex ultrasound: A review
Vascular Medicine, 2023Duplex ultrasound examinations of the mesenteric and renal circulations are commonly used to detect disease as well as to follow up patients after open surgery or endovascular intervention. The aims of this review were to present essential elements of these duplex ultrasound examinations as well as conduct a literature review of diagnostic criteria ...

Color-coded duplex endoscopic ultrasound of the adrenals
Journal of Endocrinological Investigation, 2008Imaging of the adrenals by endoscopic ultrasound (EUS) is a valuable technique for detection and localization of adrenal lesions, but endosonomorphological tumor distinction remains difficult. In this single-center study, the amount of blood flow in common adrenal lesions, such as adrenal adenomas, adrenal hyperplasia, and pheochromocytomas, was ...

Duplex Ultrasound of the Mesenteric Vessels
2014Angiography has been considered the gold standard technique for the diagnosis of chronic mesenteric ischemia. Due to its invasive nature and improvements in noninvasive diagnostic studies, angiography is currently reserved for patients with classic signs and symptoms of chronic mesenteric ischemia who have planned endovascular or open reconstruction ...

Duplex ultrasound findings in men with peyronie’s disease
Urologic Radiology, 1990Peyronie's disease is a fibrotic process involving the penis, which presents with painful erections, penile chordee, and, less frequently, impotence. Duplex Doppler ultrasound is particularly well suited to the evaluation of these patients, since it can provide information about Peyronie's plaque and the penile vasculature noninvasively.

The inter‐sonographer reliability of carotid duplex ultrasound
Australasian Radiology, 2001SUMMARYCarotid duplex ultrasound (CDUS) is a non‐invasive technique used to assess the severity of carotid artery stenosis. It has been shown to have good correlation with digital subtraction angiography (DSA) but has been criticised for its variability.

Intraoperative Duplex Ultrasound During Carotid Endarterectomy
Vascular Surgery, 2001The purpose of this study was to examine the technical aspects of intraoperative duplex ultrasound (DUS) following carotid endarterectomy (CEA), suggest criteria to differentiate significant lesions requiring immediate surgical revision from normal or benign defects, and evaluate how frequently intraoperative DUS provides useful or unsuspected ...

Diabetic nephropathy: duplex Doppler ultrasound findings
Diabetes Research and Clinical Practice, 1992To evaluate the correlations among Doppler sonographic findings, morphologic sonographic findings, and laboratory findings representing renal functional status, duplex Doppler sonography of the kidney was performed in 32 patients with diabetes mellitus.
