In the later phases of stroke recovery, ... is caused by blockage of the posterior inferior cerebellar artery (PICA) or the vertebral arteries.
Vertebral artery dissection is one of the two types of cervical artery dissection.The other type, carotid artery dissection, involves the carotid arteries.Vertebral artery dissection is further classified as being either traumatic (caused by mechanical trauma to the neck) or spontaneous, and it may also be classified by the part of the artery involved: extracranial (the part outside the skull ...
Cervical artery dissection has been noted to be a common cause of young adult strokes, with some sources indicating a prevalence of up to 20% in this young adult population with annual incidence rates between 2.6 and 2.9 per 100,000, although these incidences may be misleading with true incidences being higher because clinical presentations can vary, many being minor or self-limited, and thus ...
Hemorrhagic stroke happens when an artery in the brain leaks blood or breaks open. The leaked blood puts pressure on brain cells and damages them. ... Stroke recovery can be a long journey, but it ...
Segments of vertebral artery anterior projection. The vertebral artery may be divided into four parts: The first (preforaminal) part runs upward and backward between the anterior scalene and the longus colli muscles. In front of it are the internal jugular and vertebral veins, and is crossed by the inferior thyroid artery; the left vertebral is ...
Rotational vertebral artery syndrome (sometimes referred to as Bow Hunter's Syndrome) results from vertebral artery compression on rotating the neck. [7] The commonest cause is a bone spur from a cervical vertebra , in combination with disease in the opposite vertebral artery.
TOS doesn't directly cause SSS, because the site of subclavian artery compression is over the first rib, which is distal to the vertebral artery. TOS has been reported to cause stroke through theorized clot propagation towards the vertebral artery; [3] a similar mechanism could explain how TOS causes SSS. Presence of a cervical rib is a risk ...
Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery. [1] Cardinal signs include vertigo, headache, vomiting, and ataxia. [2]
