Background and Purpose: The aim of this study was to determine the potential value of carotid artery calcification observed on plain radiographs in patients referred for carotid angiogram in the diagnosis of carotid artery stenosis. Methods: One hundred sixty consecutive patients with suspected carotid artery stenosis underwent both plain radiographs of the carotid arteries and digital subtract...

Histological data indicate the importance of tumor vascularization as a determinant of the biological behavior and the response to radiotherapy in choroidal melanoma. Duplex ultrasound and color Doppler imaging, the combination of B-mode ultrasound and pulse-waved Doppler analysis, were used to measure quantitatively neovascular blood flow in 31 patients with choroidal melanoma. Follow-up studi...

The aim of the study was to determine whether detailed preoperative Doppler ultrasonographic examination of saphenofemoral complex can improve the results of the lower limb varicose veins surgery. Two groups of patients (30 people each) were operated due to lower limbs primary varicose veins caused by saphenous vein insufficiency. All patients had a routine duplex examination performed. Group B...

OBJECTIVE To evaluate the feasibility, efficacy and safety of ultrasound-accelerated catheter-directed thrombolysis (UACDT) in the delayed treatment of lower extremity deep venous thrombosis (DVT). DESIGN Twelve patients with unilateral iliofemoral or femoropopliteal DVT (mean symptom duration 92 ± 44 days) were prospectively investigated. METHOD UACDT was performed using recombinant human ...

BACKGROUND AND PURPOSE We routinely perform an urgent bedside neurovascular ultrasound examination (NVUE) with carotid/vertebral duplex and transcranial Doppler (TCD) in patients with acute cerebral ischemia. We aimed to determine the yield and accuracy of NVUE to identify lesions amenable for interventional treatment (LAITs). METHODS NVUE was performed with portable carotid duplex and TCD us...

A prospective study is reported of the ability of B mode ultrasound imaging and continuous wave Doppler flow studies to detect different degrees of stenosis of the extracranial internal carotid artery (ICA) in 186 arteries in 99 patients with transient ischaemic attacks (TIA) and minor ischaemic stroke. A simple mathematical equation has been developed which combines the image and flow data to ...

We present a case of an internal carotid web, detected on duplex ultrasound and confirmed by CT angiography. To our knowledge, this is only the third reported ultrasound case in the imaging literature. This vascular abnormality can cause a clinically significant carotid stenosis and is a risk factor for recurrent embolic cerebrovascular events. Due to small size and poor awareness among radiolo...

BACKGROUND AND PURPOSE Two surgical trials established that carotid endarterectomy is beneficial to symptomatic patients who have a severe internal carotid artery (ICA) stenosis on angiograms. Duplex ultrasonography-derived hemodynamic parameters show a good correlation with angiography and are often used for detecting severe ICA stenoses. However, duplex performance is ultrasound machine and o...

BACKGROUND Knowledge of the variability of a measurement method is essential for its clinical application. We investigated the variability of shunt flow measurements, since this is a relatively neglected area in the literature. In particular, no direct comparison of between-session and within-session variability was available until now. METHODS During two consecutive dialysis sessions, shunt ...

Background: Incomplete ureteric duplication can be associated with either ureteropelvic obstruction involving the lower moiety or reflux between the ureters (yo-yo reflux). Yo-yo reflux can be a cause of repeated urinary tract infection with subsequent renal damage. Aim of the work: The current study evaluated the presence of yo-yo reflux as reason of upper moiety dilation in cases with incompl...
