Ultrasound plays an important role in the assessment of carotid arterial disease, complimentary to other imaging modalities. However, ultrasound does have limitations, not least the requirement of a high degree of operator skill. Recent advances in ultrasound technology will strengthen its role by improving accuracy. This review discusses the role of ultrasound in assessing the carotid arterial...

The diagnostic procedures, indications for surgery and operative techniques for carotid artery occlusive diseases are well established, but still there is a lot of controversy regarding surgery of vertebral arteries (VAs), especially kinked VAs. Even more controversy exists about indications for surgical repair of different anomalies of VAs. The role of VAs in supplying blood to the brain and t...

Study Design Case series. Objective We report the unusual occurrence of vertebral artery injury (VAI) during routine posterior exposure of the cervical spine. The importance of preoperative planning to identify the course of the bilateral vertebral arteries during routine posterior cervical spine surgery is emphasized. Methods VAI is a rare but potentially devastating complication of cervical s...

The analysis of medical histories 129 patients aged 20 to 59 years, who suffered acute cerebrovascular disorders (AСVD) the ischemic type (IT), and participated in ATO-JFO was carried out. Anomalies cerebral arteries were found all them. A significant role hypoplasia right posterior artery, aplasia connective, left anterior as well pathological S-shaped tortuosity internal carotid vertebral the...

background: the goal of this study was to determine the reliability of tcd in evaluation of vertebrobasilar arteries in comparison with brain mra in patients suffering from acute vertebrobasilar stroke. methods: samples were patients with definite clinical diagnosis of vertebrobasilar stroke. for all patients brain mri, mra and tcd were performed during the first 48 hours of admission. basilar ...

A model for producing chronic cerebral vasospasm in monkeys by injecting autologous blood into the basal cistern is described. Spasm/narrowing was observed by angiography one hour after SAH in 8 out of 10 monkeys and in 5 of these 8, spasm was observed both one and two weeks later. No narrowing of the vessels was observed in the control cases. In monkeys that showed spasm one week after SAH, na...

BACKGROUND AND INTRODUCTION Patients presenting with posterior circulation acute ischemic events are occasionally noted to have occlusion of bilateral vertebral arteries with basilar artery blood flow entirely dependent from the anterior circulation. There is limited data about prognosis of such patients in literature. METHODS Patients with acute posterior circulation ischemic stroke and bila...
