Herein, we present a rare case of extensive chronic aortic dissection with extension to bilateral subclavian arteries, bilateral common carotid arteries, right internal carotid artery, bilateral proximal external iliac arteries and simultaneous presentation of acute embolic stroke and seizure. The rarity of this case presentation and the presence of neurological features necessitated a high ind...

The vertebral arteries branch off the subclavian arteries, passing cephalad through the costotransverse foramina of the sixth to second cervical vertebrae. They enter the skull through the foramen magnum merging at the pontomedullary junction to form the basilar artery which divides into two posterior cerebral arteries at the upper pons. At the base of the brain the carotid and basilar systems ...

The arteriograms and other findings in 42 patients with the subclavian steal syndrome were statistically evaluated to determine which factors predisposed to vertebrobasilar ischemia. Evidence of disconnection of the circle of Willis between the territories of the carotid and vertebral arteries was found in a significantly higher proportion of the patients with vertebrobasilar insufficiency. Thi...

We report the case of a 56-year-old man who presented with arterial hypotension, lightheadedness, vomiting, a sense of tingling in his right arm, and a right-beating horizontal nystagmus. He was initially admitted to the Intensive care unit and treated with standard vasopressor agents. A neurosonological examination showed the steal phenomenon on both vertebral arteries; the neuroradiological e...

A 34-year-old, single Japanese woman with active Takayasu's disease presented with stenosed bilateral common carotid arteries, subtotal occlusion of the left subclavian artery, and complete occlusion of the ipsilateral proximal vertebral artery, as demonstrated by angiography. A right subclavian-Jeft vertebral bypass using an autologous saphenous vein graft was successfully performed after 36 d...

Literature data on the etiology, clinical picture, diagnostic variants and treatment of subclavian steal syndrome are reviewed. Different clinical variants and neurological symptoms of the syndrome are described. Multispiral computed tomography, along with ultrasound examination, is important in the diagnosis of the syndrome and its causes. The use of other methods is necessary for more accurat...
