Many people worldwide are struck by a cerebrovascular accident every year.
A stroke develops when the blood flux inside the brain becomes significantly poorer or when it is interrupted. In most cases, this is due to the presence of either a blood clot blocking an artery, or to an hemorrhage produced by the rupture of an artery wall.
Any person can have a stroke, a cerebrovascular accident, at any time during their lives though, quite happily and for some years now, a specific treatment has proved effective. The results obtained will mainly depend on early detection and on the urgent implementation of the relevant treatment.
Twofold prevention programs focus on improving public knowledge of risk factors and of warning signs.
Being able to detect early signs actually proves fundamental to provide a quick medical attention.
Some symptoms of the cerebrovascular accident are:
– The paralysis or paresis of one side of the body or of a limb
– A sudden unilateral or bilateral blurred vision
– A noticeable change in sensitivity of a limb or of one side of the body
– Some difficulty while speaking
– A loss of balance
– Some difficulty understanding language
When these symptoms appear during a short period of time, they are called Transient Ischemic Accidents. These TIA usually disappear and produce no sequels though, when repeated once or more times, the risk probabilities to be struck by a larger stroke are multiplied critically.
Some brain strokes can also be preceded by sudden and very intense headaches.
When some of these symptoms show, a specialist is to be seen urgently so as to limit the extension of brain damage and the severity of post-stroke effects and, this is when early diagnosis and treatment techniques are important.
A quick and specific diagnosis will help determine the kind of stroke involved: either ischemic or haemorrhagic and help act accordingly.
The Imaging Diagnosis Unit at Vithas Xanit is equipped with all the necessary initial diagnosis techniques:
1- A CT scan is used to show any kind of hemorrhage. Evidencing an ischemic stroke is, however, not so easy since it can take up to 48 hours to identify this type of lesion.
2- An MRI scan is often used to diagnose promptly an ischemic stroke since it enables a very detailed study of the organs and helps define the area where blood supply has been interrupted.
Other diagnosis techniques can be used to determine the causes of a cerebral accident :
3- An electrocardiogram and a heart ultrasound, when a blood clot has travelled from the heart to the brain.
4- An echodoppler, when intra-arteries clots are involved.
5- An angiography and arteriography to help visualize all blood vessels and control their permeability.
The Vithas Xanit Imaging Diagnosis Unit is highly specialized and has been equipped with the latest techniques to ensure a precise diagnosis of all patients.
