Ischaemic Stroke Essay

Stroke affects everybody differently, and it is difficult to say how much of a recovery is possible. Many stroke survivors experience the most dramatic recovery during their stay in hospital in the weeks after their stroke.

Stroke previously known as Cerebrovascular accident is well-defined as ‘an abrupt cessation of cerebral circulation in one or more of the blood vessels distributing the brain. Due to the interruption or diminish of oxygen supply causes serious damage or necrosis in the brain tissues (Jauch, Kissella & Stettler, 2005). There is a presence of one or more symptoms such as weakness or numbness or paralysis of the face, arm or leg, difficulty speaking or swallowing, dizziness, loss of balance, loss of vision, sudden blurring or decreased vision in one or both eyes and headache. Stoke is categorised into two types, Ischaemic and haemorrhagic

Ischemic stroke is the blockage of blood vessels in the brain as a result of blood clots (thrombi), causing the portions of the brain nourished by the vessel and its tributaries to be starved of nutrients, poisoned, and to eventually die (“Symptoms

Aneesh Singhal, MD, author of Recognition and management of stroke in young adults and adolescents, from the Clinical Journal of the American Academy of Neurology states

Perfusion CT Imaging of Brain is a quick and convenient method of assessing perfusion disturbances in acute stroke patients. Three-color image maps with quantitative results related to patient regional cerebral blood volume (rCBV), mean transit time (MRTT) and regional cerebral blood flow (rCBF) are generated that displays stroke much earlier than the conventional CT images. Areas of less severe CBF reduction, with preserved CBV value represent “ischemic penumbra”, a term describing tissue at high risk for infarction but not yet irreversibly infracted. The larger the ischemic penumbra relative to the core, the more likely the patient would benefit from early thrombolytic therapy. If both CBV and CBF are already reduced dramatically, the

Strokes are caused by a block in the blood supply to the brain which causes a decrease in oxygen and delivery of other important supplies which facilitate proper functioning. Fifteen million cases are reported worldwide annually, although not all of these cases are mortalities, the large prevalence of strokes ranks it as the fourth leading cause of death in the United States. (Figueroa) Because of the time sensitivity associated with the lack of resources to the brain, strokes are considered a medical emergency and early recognition of symptoms can help decrease the amount of damage caused . Although strokes do not always cause death, strokes most often leave the individual with some physical and cognitive impairment.

Along with these stroke teams in hospital setting there should be emergency medical services and personnel that specialize in stroke cases on board ambulances, where imaging can be done while being transported. CT imaging and MRI should be done immediately in order to establish diagnosis of AIS or the more severe proximal artery occlusion. Imaging is effective and essential as it accurately pinpoints the area that is being occluded or suffering from ischemia. Imaging is also done while more invasive reperfusion therapy takes place using angiographic and fluoroscopic guidance. The clinical research that has been done and is taking place now has made for better outcomes for many victims of acute ischemic stroke. Without this research and imaging technology acute ischemic stroke could have claimed many sufferers. Overall, I have learned that AIS is a serious matter and is one that should be dealt with rapidly from the first sign of onset. Time predetermines patient’s functional outcomes, so we should educate and keep researching going to find ways to improve reperfusion therapy in organized systems in stroke

Multiple image technique, such as, computed tomography (CT) to scan on the brain is the first diagnostic test, magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), is more sensitive than CT scan. Nuclear medicine scanning techniques and cerebral angiogram (Caplan L. 2009; National Medicines Information Centre. 2011 and National Clinical Guidelines for Stroke. 2012).

A cerebrovascular accident more commonly known as a stroke or brain attack is the term used to describe the sudden death of brain cells in a localized area due to inadequate blood flow. In order to woke the brain needs a constant supply of oxygen and nutrients. This supply is carried to the brain

Mariam background is 60 year old lady admitted with left sided weakness and facial droop. Once confirmed stroke using the Recognition of Stroke in the Emergency Room (ROSIER) scale. Catangui (2015) states ROSIER scale is used to distinguish whether the patient is having a stroke or stroke mimics e.g. seizures or brain tumours. Computed tomography CT brain showed ischemic stroke. Ischaemic stroke is lack of sufficient blood supply to perfuse the brain/ cerebral tissue due to narrowing or blocked arteries in the brain (Morrison, 2014). According to Stroke Association (2015) statics shows that 1520000 strokes occur in the United Kingdom.

Experience with the revascularization procedures emphasizes time is a primary factor for the prediction of clinical outcome. Organizing prehospitalization care is essential to minimize the delay of therapy initiation. Transport to the closest primary stroke center or comprehensive stroke center should be immediate and rapid. It may even involve air medical transport. Implementation of the guidelines for acute care organization shortens the course of procedures in the acute phase of stroke and may improve the patient’s outcome.52 In patients with moderate or severe clinical deficit (NIHSS > 8), performing of vascular intracerebral imaging is advocated to select the subjects with large-vessel occlusion. In such

Computed Tomography (CT) scans are considered sensitive enough for detecting mass lesions, such as a brain mass or abscess, as well as detecting acute hemorrhage. It is usually operating when a patient has acute stroke symptoms and the best period to do that is after the first few hours of hemorrhage begins. The signal of computed tomography decrease after a week and may not be detectable after a few weeks. computed tomography is now proved to be one of the most convincing imaging method for hemorrhagic stroke diagnosis.

A stroke can be generally be defined in two types of categories. The first and most common type of stroke is called ischemic stroke. This occurs when a blood clot (cerebral thrombosis) blocks a blood vessel in the brain. Blood flow beyond the blood clot is then

Our brain is most complex organ system in our body. This three pound of tissue creates the main nerve center of the body. It controls our all body function, body movement, thought, and our behavior. Many of people do not know about the how a brain works? The left part of the brain controls our right side of the body and right side of brain part controls our left side of the body part. Our brain uses 20% of the total oxygen and blood in the body so it is required oxygen and nutrition from the blood for work properly. The lake of oxygen in the brain for 5 to 10-minute results in permanent brain damage or occurs a stroke. A stroke occurs when the blood supply to part of our brain is interrupted or severely reduced. A stroke is one of the diseases

Cerebral vascular accident or a stroke is the destruction of brain substance, resulting from thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. In addition, it is an area of the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke.
