The most common cause of a stroke is artery stenosis, which is the blockage of an artery in the brain by a blood clot.
The symptoms of stroke depend on what part of the brain is damaged. Signs and symptoms of stroke include: numbness or weakness of the face, arms or legs, especially on one side of the body; visual disturbances; difficulty in walking; loss of balance or coordination; and sudden severe headache.
Any of these symptoms are the signs of stroke and disturbance in the blood supply to the brain.
The Stroke Center at Ramkhamheang Hospital provides a special care for stroke patients with excellent medical facilities and advanced technologies including the followings:
• The balloon technology to treat blocked arteries.
• Magnetic Resonance Imaging (MRI): MRI uses magnetic field to perform brain imaging together with observing the blood flow in the brain.
• Computerized Tomography (CT scan): to detect bleeding or infarction (blocked artery) in brain.
• Cerebral Angiography performed in Catheterization laboratory (CATH LAB) provides a 3D model of the blood vessels in and around the brain to diagnoses the cause of stroke, to plan the treatment and to perform intervention treatment such as transcatheter thrombolytic agent administration.
Diagnosis of Carotid Artery Disease: The Cause of Stroke
There are several diagnostic techniques to determine the risk of stroke. Computerized Tomography Angiography (CTA), Magnetic Resonance Angiography (MRA) and especially Carotid Ultrasound Device are very effective diagnostic tools and are widely used internationally.
These diagnostic tests give rapid result and are more cost-effective compared to other methods. They are also painless procedures that enable doctors to diagnose the seriousness of the condition and determine the most appropriate treatment plan.
Preventing stroke with advanced carotid artery disease: Diagnostic technologies and treatments
Carotid artery disease patients can be examined by computerized tomography angiography to determine which part of the brain has been affected before doctors perform angioplasty procedure, a similar method to coronary angioplasty treatment.
To treat carotid artery disease, doctors will perform carotid artery angioplasty and stenting by inserting an umbrella-type micro catheter to trap, collect and remove embolic particles at the blockage site in the carotid artery. This helps prevent the artery from becoming narrowed or blocked during the balloon procedure. Then the insertion of a stent inside of a carotid artery is performed to support and to open the treated carotid artery. This is to improve blood flow to the brain.
