Surgical Reconstruction of Occluded Extracranial Vertebral Arteries

Extracranial vertebral artery dissection

Vertebral artery dissection (VAD) is not uncommon in the young adult population. Owing to the various clinical manifestations; the diagnosis of VAD mainly depends on imaging examinations. Ultrasound has found an increasingly wide utilization in the diagnosis of VAD because of the continuous improvement in the resolution of ultrasonic instruments and accessibility.We retrospectively collected th...

Extracranial Vertebral Artery Disease

As early as 1844, Quain1 described the anatomy and operative surgery of the extracranial vertebral artery in lithographic drawings. In 1893, Matas2 described the contributions made in the early 1800s by other sur geons such as Dietrich, Velpeau, and Maisonneuve for the treatment of penetrating trauma to the vertebral artery. In 1831, Dietrich first proposed ligating the dis tal vertebral artery...

Recently occluded intracranial and extracranial carotid arteries. Relevance of the unstable atherosclerotic plaque.

BACKGROUND AND PURPOSE It is now widely accepted that thrombotic coronary artery occlusion usually follows rupture of an unstable atherosclerotic plaque. The significance of such instability in arteries supplying the brain is less well appreciated. We therefore describe the clinical and pathological features of recent, symptomatic internal carotid artery occlusion to examine the pathogenetic ro...

Totally Occluded Arteries

The potential application of ultrasonic energy for ablation of atherosclerotic plaques was studied in human atherosclerotic arteries with continuous and pulsed delivery of energy. With a prototype ultrasonic wire probe (n=79 segments), there was gross reduction in vascular lesions as well as microscopic disruption of fibrous and calcified plaques. Normal portions of vessels appeared unaffected ...
