A stroke occurs when the flow of blood to the brain cells is compromised for a variety of reasons resulting in the development of physical weakness or a loss of senses or balance.
The clinical process of a stroke can vary within minutes and hours. As a result of the dynamic and changeable features of a stroke, patients require close monitoring and observation. The close observation in the early stages of patients who have suffered a stroke is important in terms of treatment. Patients who have suffered a stroke are closely monitored in specialist stroke units.
The Stroke Center at Acıbadem Healthcare Group provides neurological observation, brain imaging, a full range of supporting services, interventional procedures and surgical treatment around the clock. The Stroke Center is staffed by healthcare personnel who are especially trained with extensive experience in dealing with strokes.
DIAGNOSIS AND TREATMENT
An emergency assessment and intervention is performed once a patient suffering a stroke arrives at the Stroke Center. This is followed by a series of laboratory and radiological tests to determine the appropriate course of treatment.
Stroke treatment depends on the size and location of the blocked blood vessel as well as other factors including the length of time before being admitted to hospital and personal information.
Organized, experienced stroke specialists intervene in cases where patients suffer a sudden stroke. It is extremely important to rapidly determine the cause of the stroke, the risks and necessary precautions that must be taken.
Patients who complain of weakness or imbalance should begin physiotherapy and home visits as soon as possible.
Tailor made treatments for patients can include speech therapy, psychological support, diet programs, and advice from social services experts.
20% of all strokes develop as a result of cerebral hemorrhaging. This can be diagnosed using tomography and MRG techniques. Where necessary, a sample of cerebrospinal fluid may be taken for assessment.
Medical or surgical treatment may be implemented depending on the state of the patient, the cause and size of the hemorrhaging.
Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) uses a magnetic field to make images of the body which are then displayed on a computer screen. 3-Tesla MRI full body Magnetic Resonance Imaging System can perform MRI assessments during surgery. The diffusion feature provides information on hemorrhaging even in the earliest stages of a stroke.
Computerized Tomography (CT)
Computerized Tomography (CT) is one of the first imaging methods implemented to diagnose the occurrence of a stroke. The X-rays used create sliced images of the brain which are examined on a computer screen.
The Stroke Center is equipped with a 16-channel, multi-slice CT device which reduces the filming time from 10-15 minutes to 1-2 minutes. This enables stroke patients to save time. The perfusion feature enables strokes to be diagnosed in their early stages and provides information about hemorrhaging.
Digital Subtraction Angiography (DSA)
Digital Subtraction Angiography (DSA) is a technique where images are acquired by inserting a catheter into an artery in the groin which is then injected with a contrast medium while being exposed to X-rays.
The same catheter is used to treat blocked blood vessels during the procedure. Medication can be given to unblock the blood vessel while balloons or stents can be applied where the blood vessel has narrowed.
Color Doppler Ultrasound (CDUS)
This technique bounces sound waves off blood cells to produce computerized images in different colors of data obtained at varying frequencies regarding the direction and speed of tissues. This helps differentiate arteries and veins. This assessment provides valuable information regarding obstructions or narrowing of blood vessels as well as providing information about blood flow.
This technique reflects the electrical activity of brain waves by using special conductors which are placed on the scalp.
EEG testing is used in situations involving a loss of consciousness, a lack of lucidity and suspected epilepsy. Portable EEG units enable testing to be performed during surgery or at the bedside of a patient.
This procedure enables continuous EEG recordings with a simultaneous video recording of patients who have suspected epilepsy but whose seizures are yet to be documented. This procedure can take place while a patient is either asleep or awake.
Positron Emission Tomography (PET/CT)
These tests, which yield valuable information, are carried out in many fields of medicine. They provide important information about cerebral hemorrhaging in later stages of strokes as opposed to the emergency and early stages.
