Bow Hunter's syndrome is an uncommon condition in which the vertebral arteries is symptamatically occuled during neck rotation. This mechanical occlusion or stenosis can sometimes result into a Bow Hunter's stroke. As we all know, the vertebral arteries supply blood to the posterior part of the brain by way of the basilar artery and then the posterior cerebral arteries. In some special cases of Bow hunter's syndrome, patients can have what appears to be a normal vertebral artery on one side but on the opposite side can have an occluded artery while their head is in a nuetral position. Usually one of the vertebral arteries become occuled when turning their head a specific degree to one side while the other side becomes occluded in the c1-c2 area of the cervical spine. Stenosis of the vertebral artery can be in result of a cervical spine abnormality that pinches the blood flow when traveling through the transverse foramen. Angiography is the most common procedure preformed to find the occlusion or stenosis of the artery. In most cases a vertebral angiography can locate where in the artery the occlusion originates or depicts the mass or tumor causing stenosis.
SYMPTOMS:
Are typically the same as in other stroke victims: dizziness, vision disturbance, trouble speaking and walking, confusion and severe headaches.
The damage will start immediatly after the infarction occurs. If ever experiencing these symptoms go to the nearest emergency room for medical assistance. The sooner the better for a chance at full recovery.
TREATMENT:
Angiography followed by and interventional procedure angioplasty and stenting.
