A stroke, sometimes referred to as a cerebrovascular accident (CVA), is the rapid loss of brain function due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis, arterial embolism), or a hemorrhage.…
Mr. K. was diagnosed as having an acute cerebral vascular accident. This disorder can also be described as a “stroke”. It occurs when there is an interruption of normal blood flow in one or more of the blood vessels that supply the brain. Thrombosis, embolism, and hemorrhage are the primary causes of a CVA. (Sommers and Johnson 2002) The tissues of the brain become ischemic, leading to hypoxia or anoxia with destruction or necrosis of the neurons, glia, and vasculature. Complications of CVA include unstable blood pressure, sensory and motor impairment, infection, pneumonia, contractures, and pulmonary emboli. CVA is the third leading cause of death in the United States and affects more than 500,000 Americans annually. (Sommers and Johnson 2002)…
The patient prognosis it is more positive in an ischemic stroke than in the hemorrhage stroke since ischemic stroke kills the cells of the brain, the hemorrhage strokes has more risk and complications by increasing intracranial pressure and spams in the brain (Purushothaman, Salmani, Prarthana, Bandelkar, & Varghese, 2014). Many people who suffer from CVAs recover their level of independence. Many other stay with minor disabilities and unfortunately about a 40 percent end up with severe disabilities (Purushothaman, Salmani, Prarthana, Bandelkar, & Varghese,…

Cerebrovascular accident (CVA) is the medical term for what is commonly termed a stroke. It refers to the injury to the brain that occurs when flow of blood to brain tissue is interrupted by a clogged or ruptured artery, causing brain tissue to die because of lack of nutrients and oxygen.…
Strokes are the third most common cause of death and in middle-aged or elderly people, it is the most frequent cause of a disability (Bledsoe, p.g.198). There are two broad categories of strokes, ischemic strokes and hemorrhagic strokes. Ischemic strokes are caused from a blockage in the artery which results in a lack of blood flow to the brain tissue. Hemorrhagic strokes are caused by a hemorrhage from a ruptured cerebral artery (Bledsoe, p.g. 198). An occlusive stroke, also known as an ischemic stroke is when a cerebral artery is occluded by a blood clot. The blockage results in ischemia (an inadequate amount of blood supply to the brain tissue) which results in infarction. The dead tissue will swell causing further damage to the surrounding tissues (Bledsoe, p.g.198). If the swelling is severe, it could lead to herniation which is the protrusion of brain tissue from the skull through the foramen magnum (Bledsoe, p.g.198). There are different types of ischemic strokes. An ischemic stroke that is caused from an embolus that was carried to the cerebral blood vessels from a remote site is also known as an embolic stoke (Bledsoe,…
Annually, around 800,000 Americans have strokes when a blood blocks the circulation to the brain or when a blood vessel in the brain breaks. When this happens, brain cells are deprived of oxygen and die off. Additionally, memory, muscle control and other abilities controlled by that area of the brain are lost.…
There are two different types of strokes that a person could have. They are ischemic and hemorrhagic; ischemic stroke occurs when a blood vessel is blocked from a clot and hemorrhagic stroke occurs when a blood vessel bursts which results in it bleeding into the brain. If I had a choice about what type of stroke I would want to have I would go with the ischemic stroke. The reason why I would go with the ischemic stroke is because there is a drug called tissue plasminogen activator (t-PA), which breaks the clots down and allows the blood vessel to go back to a normal blood flow. The ischemic stroke is also the most common and least severe stroke. I would have a higher chance of being able to live my life normally with it. If I had a choice…

Thrombotic strokes are caused by clots that were formed or originated from within the brain itself. Thrombotic strokes occur when vessels in your brain are damaged and your brain is trying to repair itself by forming clots. Unfortunately this occludes the vessels. Also one of those clots might free itself from a particular area in the brain and travel to a surrounding healthy vessel causing the blockage there. Thrombotic strokes may take years in the making. Embolic strokes are when the clot or debris originated from outside the brain and traveled there causing the stroke. Once in the brain it reacts similarly to the thrombotic stroke causing ischemia. One thing to be concerned about with embolic stroke is the fact another stroke will…
There are three different kinds of stroke. One of the most common stroke is called Ischemic stroke. About eighty-five percent of strokes are ischemic strokes. It happens when the arteries to your brain become blocked, causing blood flow. The two common ischemic strokes are the Thrombotic stroke and Embolic stroke. When a blood clot forms in one of the arteries into your brain, the thrombotic stroke then occurs. It may caused by a fatty deposits that build up in the arteries and also reduces blood flow. An embolic stroke occurs when a blood clot forms away from your brain commonly in the heart. It is when embolus…
About one third of strokes can be followed by transient ischemic attacks (mini-strokes). These strokes temporarily interrupt blood flow to the brain and cause similar symptoms like sudden vision loss or temporary weakness in a limb. Quick treatment can improve the chances of survival and increase the degree of recovery. A person who may have suffered a stroke should be seen in a hospital emergency room immediately. To be most effective, blood clot prevention treatment should begin within three hours of a stroke.…
