Info Vertebral Artery Test
Approximately one‐quarter of ischaemic strokes require the posterior or vertebrobasilar circulation. Stenosis of the vertebral artery tin laissez passer on inwards either its extra‐ or intracranial portions, as well as may concern human relationship for upwards to 20% of posterior circulation ischaemic strokes. Stenotic lesions, especially at the rootage of the vertebral artery, are non uncommon. In an angiographic report of 4748 patients amongst ischaemic stroke, around grade of proximal extracranial vertebral artery stenosis was seen inwards 18% of cases on the correct as well as 22.3% on the left. This was the minute almost mutual site of stenosis after internal carotid artery stenosis at the carotid bifurcation. Such stenotic lesions are forthwith potentially treatable yesteryear endovascular techniques.
In marked contrast amongst carotid artery stenosis, the optimal administration of vertebral artery stenosis has received express attention, as well as is poorly understood. This partly reflects difficulties inwards imaging the vertebral artery adequately, as well as express surgical handling options. Recent improvements inwards imaging as well as the arrival of vertebral artery angioplasty, however, convey opened upwards novel opportunities for intervention inwards this disease.

The handling inwards such cases is purely medical. However, a Physical Therapist should live aware of this problem, the vertebral artery illness or vertebrobasilar ischaemia, as well as should know the basic anatomy, symptoms as well as assessment exam inwards his everyday practise.
H5N1 rattling prissy article on Physiopedia explains these issues clearly.
What to proceed inwards mind:
To exam the blood menses inwards the vertebral artery, i should pose the patient on his dorsum as well as perform an passive extension, followed yesteryear a passive rotation of the neck. The rotation should live performed inwards both directions. The manoeuvre causes a reduction of the lumen at the 3rd partitioning of the vertebral artery, resulting inwards de decreased blood menses of the intracranial vertebral artery of the contralateral side. It causes an ischemia due to blood loss inwards the pons as well as the medulla oblongata of the brain. This results inwards dizziness, nausea, syncope, dysarthria, dysphagia, as well as disturbances of the hearing or vision, paresis or paralysis of patients with vertebrobasilar ischaemia.
