BACKGROUND AND PURPOSE We sought to evaluate the diagnostic value of echo-enhanced transcranial color-coded duplex sonography (TCCD) and the clinical relevance of vascular pathology assessed by sonography for early clinical outcome in acute ischemic stroke. METHODS We present 23 consecutive patients with an anterior circulation stroke in whom clinical examination, CT, and ultrasonography were...

Carotid body tumors (CBTs) are rare, slow-growing tumors that should be considered in evaluating every lateral neck mass. This single center study was performed to define demographic features, clinical characteristics and remedies of Iranian patients with CBT. A retrospective review of prospectively collected data was done on 45 patients with 50 CBTs who have been referred to Sina Hospital, Teh...

AIM To report a patient with diabetic rubeosis who suffered from acute retinal ischemic change and stroke after intravitreal injection of bevacizumab. METHODS A 55-year-old man had diabetes with unilateral rubeosis and macular edema. Three days after receiving intravitreal injection of bevacizumab (1.25 mg in 0.1 ml), he developed acute vision loss and change of consciousness. A complete ocul...

OBJECTIVE The purpose of this study was to prospectively investigate the role of high-resolution and color Doppler sonography in the differential diagnosis of acute scrotum and testicular torsion in particular. METHODS Patients who underwent sonography for acute scrotum between April 2000 and September 2005 were included in the study. Gray scale and color Doppler sonography of the scrotum was...

BACKGROUND AND PURPOSE We hypothesized that direct cervical investigation with Power M-Mode Doppler (PMD) combined with single-gate Doppler spectral analysis (SGDSA) using a 2-MHz pulsed-wave Doppler transducer would show reasonable accuracy parameters when compared with standard color-coded carotid duplex ultrasound (CDU). METHODS We prospectively screened for cervical internal carotid arter...

BACKGROUND AND PURPOSE The transcranial color duplex sonography technique was applied to the vertebrobasilar-posterior system to provide normal data for clinical application. METHODS The intracranial posterior circulation was studied in 49 healthy volunteers (mean +/- SD age, 35 +/- 12 years) by a transcranial and suboccipital approach with a 2.0-MHz sector transducer of a computed sonography...

Standardization of Carotid Ultrasound To the Editor: The article by Ranke et al1 in the February issue of Stroke represents an excellent advancement in Doppler grading of carotid artery stenosis. Since many surgeons now depend on Doppler ultrasound for decisions for carotid endarterectomy because of the costs and dangers of angiography and the cost and resolution problems of magnetic resonance ...

AIM Evaluation of the diagnostic contribution of color duplex sonography of the temporal, carotid and vertebral arteries and doppler sonography of the periorbital arteries in patients with and without giant cell arteries (GCA) particularly to distinguish between arteritic and nonarteritic neuro-ophthalmological vascular complications (NOC). METHODS In a prospective study ultrasonographic find...

We assessed the potential of 2-MHz pulsed-wave transorbital Doppler ultrasonography to delineate the role of the ophthalmic artery as a source of collateral cerebral blood supply by comparing oculopneumoplethysmography, transorbital Doppler ultrasonography, periorbital continuous-wave Doppler ultrasonography, and transcranial Doppler ultrasonography in 25 patients with unilateral internal carot...
