Ischemic Stroke can bring about many complications and one of its impediments is neurological deficits and debilitating effects.
Certain damages can occur to patient who experienced an Ischemic Attack. It may involve disruptions in various systems of the body. Because of this reason, it is also necessary for the patient to undergo series of therapies to improve his condition.
What are the Diagnostics Exams for Ischemic Stroke?
A patient who is exhibiting neurologic deficits is cautiously examined on the aspects of his physical and neurologic functions. On the first assessment, it focuses on the patency of the patient’s airway which can be at risk by the loss of cough or gag reflex and altered status of the respiratory system; cardiovascular condition including cardiac rate and rhythm, blood pressure and carotid bruit; and gross neurological dysfunctions.
Patients with this condition may be present in an acute care facility during the manifestation of some neurologic symptoms. A TIA or Transient Ischemic Attack is a dysfunction of the neurologic responses that typically last for not over 24hrs with most of cases resolve within an hour. It is indicated by abrupt lost of motor, sensory and visual functions. The symptoms are the outcome of the blood flow impairment to a specific area of the brain. This TIA can serve as a warning sign of an imminent TIA stroke attack. An abysmal evaluation and a late treatment may result to an irreversible damage to the brain or even death.
A Carotid Ultrasound can be suggested to perform using a carotid duplex that measures the artery’s width and the process of blood flow through it. This device can verify the severity of atherosclerotic build up and blocking or narrowing of the carotid artery which supplies the largest amount of blood to the brain.
Computed Tomography or CT scan and the Magnetic Resonance or MRI is a high definition tests that can provide the physician a definite image of the heart and brain. Those tests can supply the medical team a clear image of clots and hemorrhages. The Cerebral Angiography is an insidious procedure that is used for patients who have TIAs who needs surgery. It is as well used to identify aneurysms and for thrombolytic therapy monitoring. This procedure requires the introduction of a catheter in the femoral artery that is located at the patient’s groin then moves up until it reaches the base of the carotid artery. During this time, a contrast dye is injected and an X-ray may be constituted.
Other techniques are also performed such as Positron Emission Tomography or PET and the Single Photon Emission Computed Tomography or SPECT, may also facilitate the identification of damages due to stroke.
What are the Preventive Measures for Ischemic Stroke?
associated with Diseases of the Heart has its preventive measures. Stroke susceptibility screenings are the idyllic opportunity to lower its occurrence by determining the groups or people who has the greatest chance to have it. After knowing the target population, you can start by educating them and their community about early diagnosis and prevention of stroke. Recent studies have proved that a low dose of aspirin therapy may decrease the risk for women.
Old age, race and gender are the common non modifiable factors that increase the risk of stroke. The occurrence of stoke may increase his susceptibility as a person ages. Males have the highest likelihood of stroke. African-Americans almost have twice the chance of having this condition. The common modifiable factors are hypertension, obesity, hyperlipidemia, diabetes and smoking. Several techniques can prevent the recurrence of stroke. An introduction of early treatments after transient ischemic attacks will save the patient’s life.
What are the Treatments for Ischemic Stroke?
The goal of the Stoke Therapy is to re-establish the blood flow to the affected region of the brain as soon as possible. The medications used for the prompt treatment of Ischemic Stroke are aspirin, alteplase and anticoagulants.
Alteplase is a thrombolytic drug that is commonly known as TPA or the tissue plasminogen activator. It works as a clot dissolver that clears the occluded part of the arteries in the brain. The advantage of these drugs is that it can be slowly decreased after several hours. Time is in utmost importance with this treatment because the earlier it’s given the higher survival rate the patient has.
Aspirin is an antiplatelet drug, on the contrary on what many people perceive that it’s a thrombolytic drug. It can help to prevent new clot formation within blood vessels. It is the solely antiplatelet drug which can be given in the acute phase of the condition and is proven to have an effective outcome.
Diseases of the Heart that are related to the occurrence of Ischemic Stroke are provided Anticoagulants such as Warfarin and Heparin. They decrease the chances of forming additional clots due to the response of the body during excessive bleeding. The body will activate its cells to form clots to prevent further bleeding. Anticoagulants interfere in that process. The surgical management for this condition is carotid endarterectomy and a possible craniotomy with craniectomy.
