Stroke in Evolution VS Completed Stroke
A stroke in evolution is defined as; ischemic neurologic symptoms that actively worsen during a period of observation. A completed stroke is defined as; stable neurologic deficit that had sudden onset and persists longer than 3 weeks. In a stroke in evolution symptoms come and go, which is considered unstable. Whereas a complete stroke, no progression or resolution of the symptoms, which is considered stable. (Davies, 2015. Print.) What is a stroke? A stroke is also known as a cerebrovascular accident, which produces a permanent neurologic deficit. Strokes occur due to problems with the blood supply to the brain. The blood supply is either blocked or a blood vessel within the brain ruptures, causing tissue death in the brain. A stroke is considered a medical emergency, and treatment must be given as quickly as possible. (Davies, 2015. Print.) Are you at risk of a stroke? If you are over 55, African American, family history of strokes or have a genetic condition like sickle cell, then you are more likely to have a stroke. Pregnant women are also at a higher risk for a stroke because of the elevation of estrogen in the body. These are the risk factors that are unchangeable. …show more content…
For the tests mentioned above some of the limitations are as follows, nonintact skin, movement of patient, the depth needed, shadowing, and even thickening of the temporal bone. Any of these limitations will result in a rescheduling of the study, or a different approach will need to be taken. When doing the study, the sonographer may come across artifacts. For example aliasing artifact is the misrepresentation of doppler signal. Another example would be crosstalk, which is a mirror imaging. Some artifacts may be mistaken for plaque, so it is important for the sonographer to really analyse what they are viewing. (Davies, 2015.
