Duplex scanning in extracranial vertebral artery dissection.
نویسندگان
چکیده
Ultrasonic (duplex scanning and continuous-wave Doppler) and angiographic findings in three patients with bilateral extracranial vertebral artery dissection are reported. A pattern of ultrasonic anomalies diagnostic of dissection is described, including association of a localized increase in diameter of the artery with hemodynamic signs of stenosis or occlusion at the same level and decreased pulsatility and presence of intravascular echoes in the enlarged segment.

Background and Purpose: In this study we analyzed the value of ultrasound examination for diagnosis of vertebral artery dissection. Methods: The vertebrobasilar arterial system was assessed in 14 patients using transcranial and extracranial pulsed-wave Doppler and duplex sonography. Results: The dissections were verified by angiography (in 1 patient), magnetic resonance imaging (in 5), or both ...
متن کاملDuplex scanning of normal vertebral arteries.
Vertebral arteries were studied by Duplex scanning in 50 normal subjects. Pretransverse and C6-C5, C5-C4 intertransverse segments were visualized in all cases on both sides; segment C4-C3 was visualized in 100% of the cases on the right side and in 90% on the left; ostium was obtained in 94% of the cases on the right and in 60% on the left. The left vertebral artery was dominant in 48% of the c...

Introduction Dissection of a cervical artery supplying the brain is a major cause of stroke in young adults. It can occur spontaneously, in connection with an underlying disorder such as fi bromuscular dysplasia, 1 -antitrypsin defi ciency, hypertension, migraine, atherosclerosis, arteritis or Marfan’s disease [1, 2] . More often, it is related to a neck trauma. In the case of a vertebral arter...
