What neuro deficit would be seen with an infarction in the basilar artery?
|
CNS abnormalities
contralat full body weakness coma/alterations in consciousness decreased sensation vertigo, loss of coordination, difficulty speakingg, vusual abnormalities Vertebrobasilar insufficiency may happen when the neck is overextended back into a sink during hairwashing, damaging the blood vessels in the neck and disrupting the blood flow to the brain, resulting in a potential stroke. Vertigo (commonly described as the environment spinning or as if the person is twirling in space) is the most recognizable and quite often the sole symptom of decreased blood flow in the vertebrobasilar distribution. The vertigo due to VBI rarely is brought on by head turning, which could occlude the ipsilateral vertebral artery and result in decreased blood flow to the brain if the contralateral artery is occluded. When the vertigo is accompanied by double vision (diplopia), graying of vision, and blurred vision, patients often go to the ophthalmologist. If the VBI progresses, there may be weakness of the quadriceps and, to the patient, this is felt as a buckling of the knees. The patient may suddenly become weak at the knee and crumple (often referred to as a “drop attack”). Such a fall can lead to significant head and orthopedic injury, especially in the elderly. Transient ischemic attacks due to VBI will, by definition, have symptoms resolved within 24 hours. More often, however, the symptoms are very brief, lasting a few seconds to half an hour. Though uncommon and thought to affect only people with already weakened neck arteries, the syndrome has been at the centre of a debate in several recent stroke deaths. |
