BACKGROUND Reopening of an occluded internal carotid artery (ICA) is often seen in dissections but only rarely occurs in atherothrombotic occlusion of the internal carotid artery. CASE DESCRIPTION A 60-year-old man suffered a minor stroke with dysphasia in March 1995. Color-coded duplex ultrasonography of his neck arteries revealed a left ICA occlusion. He was placed on a regimen of aspirin a...

STUDY DESIGN Prospective imaging study. OBJECTIVE To clarify the frequency of positional vertebral artery (VA) occlusion using duplex ultrasonography in patients with rheumatoid arthritis (RA). SUMMARY OF BACKGROUND DATA Some patients with upper cervical RA develop thromboembolic stroke related to positional and transient VA occlusions; however, whether RA patients have positional VA occlus...

OBJECTIVES Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after microbubble contrast injection) add informa...

BACKGROUND Duplex ultrasonography criteria for assessing the severity of carotid artery (CA) in-stent restenosis are not well established. METHODS AND RESULTS We analyzed 39 patients (40 CAs) who underwent CA stenting with baseline and 6-month follow-up carotid duplex ultrasonography and intravascular ultrasound. Intravascular ultrasound measurements included minimum luminal diameter, percent...

BACKGROUND Non-recurrent inferior laryngeal nerve (NRILN) is usually discovered during thyroid surgery. It is often associated with vascular abnormalities that can be detected with magnetic resonance imaging (MRI) or duplex ultrasound scan. The aim of this study was to compare the diagnostic sensitivity of ultrasonography with MRI to identify the vascular abnormalities associated to NRILN. PA...

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...
