BACKGROUND The purpose of this prospective study was to determine the clinical usefulness of captopril renal scintigraphy and duplex Doppler sonography in detecting haemodynamically significant renal artery stenosis (> or = 60%) and predicting cure or improvement of hypertension following revascularisation. METHODS Twenty-eight patients with moderate or high index of clinical suspicion of ren...

background: the aim of this study was to evaluate the impact of diabetes mellitus (dm) on peripheral vascular disease (pvd) in patients with coronary artery disease (cad). methods: a total of 13702 consecutive patients who underwent coronary artery bypass grafting (cabg) at tehran heart center between january 2002 and march 2007 were included in this study. the demographic data, pvd, and outcom...

background: we tested whether hepatic haemodynamics assessed by doppler ultrasonography can be a predictor of response to therapy in patients with non‑alcoholic fatty liver disease (nafld) to prevent further unnecessary diagnostic tests and interventions. methods: forty eight consecutive patients affected by nafld, who refered to some clinics in tabriz, iran between 2009 and 2011 were included ...

AIM To investigate the potential usefulness of contrast-enhanced three-dimensional (3D) power Doppler sonography in the differentiation of benign and malignant adnexal lesions. METHODS Thirty one patients with complex adnexal lesions of uncertain malignancy at transvaginal B-mode and/or color Doppler sonography were prospectively evaluated with three-dimensional power Doppler sonography befor...

The persistent hypoglossal artery is rare vascular anomalies. We report the case of a 50-year old man with right hypoglossal artery, ipsilateral hypoplasic internal carotid artery, associated with left proximal subclavian stenosis with subclavian steal syndrome. Power-Doppler-Ultra-Sonography spectral images obtained after the patient exercised the left arm showed mid-systolic deceleration with...

BACKGROUND AND PURPOSE Accurate carotid Doppler examination is an important issue in the light of large endarterectomy trials, but recommended cutoff values for detection of >70% stenosis vary widely. Standardization of diagnostic criteria should consider patient variation and instrument variability. METHODS We prospectively analyzed various Doppler parameters in 44 patients undergoing caroti...

Doppler ultrasound is a noninvasive technique that allows the examination of the direction, velocity, and volume of blood flow. Doppler ultrasound has proven to be a valuable technique for investigation of artery conditions. Therefore, Doppler ultrasonography is known as reliable technique, which demonstrates the flow characteristics and resistance of internal carotid arteries in stenosis and o...

This cross-sectional study was designed to determine the prevalence of carotid artery atherosclerosis in patients with pulsatile tinnitus. All patients who had pulsatile tinnitus and presented to the otolaryngology clinic of Rasoul Akram Hospital, Iran University of Medical Sciences, and to some other private hospitals and clinics were referred to a tertiary referral center. From November 1999 ...
