Artery Of Percheron Essay

There are two major branches of strokes: those caused by narrowing or blockage of the arteries leading towards the brain, and those caused by blood vessel leaking or rupturing in the brain. Ischemic strokes account for approximately 87% of Stroke cases, which reduces the blood flow to the brain. About half of the Ischemic strokes are caused by clotting in small or large arteries, a smaller portion are caused by

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

Upon my arrival, I was approached by a preacher who advised me the gentlemen that passed away, Darren Allen Veatch, who was later identified, is up stairs in his bed room. I then walked up stairs observing two bed rooms, one on the south side of the residence and one on the north side. I approached the bedroom on the north side of the residence observing a brown in color blanket covering the bed room. I pulled the blanket back observing Darren Veatch lying face down with his head facing towards the east wall. I then observed levity on Darren Veatch legs, stomach, chest and facial region. ETMC EMS

When an artery in the brain is block (ie; TIA) open collateral vessels can allow blood to

Neuroradiological imaging plays an important role in the process of diagnosing ischaemic stroke. The different imaging modalities that can be used to diagnose ischaemic stroke include computed tomography (CT), magnetic imaging resonance (MRI), and radionuclide imaging. In this article, the different modalities that contribute to the diagnostic process are discussed, with a focus on CT scan protocols.

On 7/6/2015 S/O EMT Perez was dispatched to WC-407 regaurding a pendant alarm. S/O EMT Perez knocked and annoounced his presence at the door, when there was no answer S/O EMT Perez proceeded to search the apartment. S/O EMT Perez found the resident, a Mrs. Mary Beiter toppled over her walker by her bedside. Mrs. Mary Beiter was trying to get inter her bed when she lost balance and fell and could not get up under her own strength. Mrs.Beiter did not complain of any hip pain during the pelvic exam but did state that she has a bad knee and hip that makes it rather hard to stand on her own. S/O EMT Perez asked Mrs.Beiter if she wanted to be transported to the hospital before he picked her up which she declined. S/O EMT Perez performed a lift assist

Strokes are caused by pathophysiological changes. The two major mechanisms of stroke consist of ischemia and haemorrhage. Ischemia is when there is no oxygen or not, merely enough oxygen to fuel the tissue level in the body. Haemorrhage in the brain, causing strokes can be due to non-traumatic intracerebral haemorrhage (Shah, MD, n.d.) (see appendix 1). This essay will further discuss the implications of strokes on a cellular, organ and system level. Explain the clinical presentation of the signs and symptoms of strokes and how the condition will be managed by a paramedic.

“The patient is Adam Rudd, a 78 y/o white male with a history of hypertension. He has been diagnosed with hypertension past 15 years and is on anti-hypertensive medications and aspirin. He is very weak and short of breath. He is accompanied with his longtime friend Jennifer, who reports that Rudd was looking very weak and was complaining of severe headache and blurred vision before coming to the hospital. He is 5’9” and weighs 270 lb. Vital signs recorded were: oral temperature 98.20 F, BP 224/120 mm Hg with a heart rate of 102 beats/minute and respiration of 24 breaths per minute. The pulse oximetry reading was 94% on room air. He is complaining of severe headache and blurred vision. Rudd said that he did not take his antihypertensive medication or aspirin since he ran out of pills. He has not been taking his medication for past 15 days. He reports no known allergies to any medications or other substances.”

Cerebrovascular accidents, or strokes, will lead to brain damage that affects the functioning of executive function, memory, language, visuospatial performance and emotional states. Corresponding vertebral arteries and carotid arteries provide blood to the brain from the heart that the carotid arteries are internal and external sections of the thyroid cartilage. Where the optic nerve rests the internal artery distributes into the anterior and middle cerebral arteries. The vertebral arteries arise through the spinal vertebrae and meet the lower pons to form the basilar artery. The brain receives 15% to 20% of the oxygenated blood from the heart and can only endure fleeting interruptions of blood flow before neural operations

Correspondingly, there are two pathways that transports blood to the brain called internal carotid artery and vertebral artery. The internal carotid artery has three layers call the tunica adventitia, tunica media, and tunica intima. Tunica intima is made up of smooth muscle cells and elastin. The basilar artery forms and it branches out to the posterior cerebral arteries. The posterior cerebral arteries form the internal carotid arteries and when they connect they make cerebral arterial circle ( circle of willis). The middle cerebral arteries branch out two separate arteries called the anterior cerebral arteries. Each of these arteries are the force that direct the blood flow to the brain. There are three tiny vascular systems that work together to profuse the deep brain. Which are the pial, subependymal, and lenticulostriate arteries. The small area of white matter that depends on blood flow is called the subcortical “shed water” area. The subcortical is more prone than other areas of the brain to have ischemia. The leading cause of ischemia is the fibrin builds up and this cause a narrowing of the lumen. Which does not allow the flow of red blood cells and deprives the white matter of tissue of oxygen. The tissue then losses density and produces white matter lesions. The neurons become demyelinated which leads to loss of cognitive ability.

Mr X, a 60 year- old Caucasian male, admitted to the stroke unit with a diagnosis Left MCA infract. He presented to the emergency department right sided hemiparesis, neglect of affected limbs, dysphasia and right side facial droop. He was on cardiac monitor for close observation for 48 hours. Stroke critical care pathway and commenced and care provided as per protocol.. Stroke is a serious and deadly condition including cerebral circulation within the brain and can extremely affect a person ability to maintain a safe environment, communication and mobility as well as other activities of living. The purpose of this essay is to give an overview of the Pathophysiology of ischaemic stroke, the required nursing care and the rationale behind it, followed by medical management and treatment provided to the patient.

Intracerebral hemorrhagic stroke occurs when vessels within the brain leaks blood into the brain itself. It often happens without warning. This type of stroke represents about 10% of all strokes. The most common cause is uncontrolled high blood pressure or (Hypertension.) Hypertension can cause small arteries inside the brain to become brittle and susceptible to cracking and rupture. Less often it may result from a blood vessel defect present since birth.

A stroke caused by a blocked artery by a blood clot or bursting of a blood vessel because of uncontrolled high blood pressure. There are main three types of the stroke. An ischemic stroke occurs when a blood clot blocks one of the arteries which supply blood to brain. A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions. (mayo clinic). About 89%, strokes are ischemic strokes. Ischemic stroke includes thrombotic stroke. A thrombotic stroke occurs when a thrombus stuck in one of the arteries that supply blood to the brain. A clot build-up of fatty deposits in arteries. Another type of stroke is called the hemorrhagic stroke. This stroke occurs when a blood vessel leaks or ruptures in the brain. A bold vessel leaks or ruptures from many conditions like uncontrolled high blood pressure or overtreatment with anticoagulants and the weak spot in blood vessel walls. (mayo). Some people experience a mini-stroke it is known as a transient ischemic attack (TIA). A temporary decrease or clot stuck in a vessel in our brain causes TIA. It happens less than five minutes. This stroke does not have any symptom, because the blockage is
