Vertebral artery dissection (VAD) is a flap-like tear of the inner lining of the vertebral artery, which is located in the neck and supplies blood to the brain. After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow. The symptoms of vertebral artery dissection include head ...
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 ...
Neurosurgery. Anterior spinal artery syndrome (also known as "anterior spinal cord syndrome") is syndrome caused by ischemia of the area supplied by the anterior spinal artery, resulting in loss of function of the anterior two-thirds of the spinal cord. The region affected includes the descending corticospinal tract, ascending spinothalamic ...
In fact, acute sulcal artery syndrome should be suspected in patients with acute hemicord syndrome, and vertebral artery dissection should be suspected in cases of high cervical cord involvement. In a recent review by Tan YJ, et al. in 2021, good functional recovery was seen in most, and vertebral artery dissection was the leading cause of ...
Posterior spinal artery syndrome (PSAS), also known as posterior spinal cord syndrome, is a type of incomplete spinal cord injury. [1] PSAS is the least commonly occurring of the six clinical spinal cord injury syndromes, with an incidence rate of less than 1%. PSAS originates from an infarct in the posterior spinal artery and is caused by ...
The vertebral arteries are major arteries of the neck. Typically, the vertebral arteries originate from the subclavian arteries. Each vessel courses superiorly along each side of the neck, merging within the skull to form the single, midline basilar artery. As the supplying component of the vertebrobasilar vascular system, the vertebral ...
Vascular myelopathy (vascular disease of the spinal cord) refers to an abnormality of the spinal cord in regard to its blood supply. [1] The blood supply is complicated and supplied by two major vessel groups: the posterior spinal arteries and the anterior spinal arteries —of which the Artery of Adamkiewicz is the largest. [2]
Neurology. Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow (ischemia) in the posterior circulation of the brain. The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex. [1]
