Simultaneous vertebral and subclavian artery stenting
INTRODUCTION Vertebrobasilar territory ischemia leads to disabling neurological symptoms and may be caused both by vertebral artery (VA) and subclavian artery (SA) stenosis. The coexisting symptomatic ipsilateral VA and proximal SA stenosis should be considered as a true bifurcation lesion for percutaneous treatment. AIM To evaluate the safety and efficacy of simultaneous angioplasty of verte...
متن کاملAnatomical Variations of Vertebral Artery
Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
متن کاملAngioplasty of subclavian artery stenosis proximal to the vertebral origin.
Percutaneous transluminal angioplasty was performed in nine patients with symptomatic proximal left subclavian artery stenoses. All cases were technically successful. One significant delayed complication occurred in a patient whose common carotid-to-subclavian artery bypass graft occluded several months after a successful subclavian artery angioplasty with a probable subsequent embolic occlusio...
متن کاملSubclavian steal syndrome from the ipsilateral vertebral artery.
We present two cases of subclavian steal syndrome from the ipsilateral vertebral artery (VA) to the subclavian artery (SCA), one with the left VA originating from the aortic arch and the other with the left VA originating very close to the origin of the SCA, proximal to the occluded segment. In both cases, angiographic demonstration of these anatomic variations and successful endovascular treat...
متن کاملAnatomical Study of Subclavian Artery and Its Branches
Background: The branches of right and left subclavian arteries are important in conducting of blood to spinal cord, posterior cranial fossa, base of the neck, thyroid gland, wall of the thorax and abdomen. The routine use of internal thoracic artery as a conduit in coronary artery bypass grafting surgery requires appreciation of the anatomical variations of these vessels. So far, there is not a...
