Difference Between CVA and Stroke

关键区别 - CVAvs中风

中风被定义为年代yndromeof rapid onset of the cerebral deficit which is lasts for more than 24 hours or leads to death with no apparent cause other than a vascular one. CVA orcerebrovascular accidentis the fancy medical name given to strokes. So both these terms essentially mean the same thing. Thus, there is no specific difference between CVA and Stroke. However, we will discuss here in detail the types of stroke such as ischemic stroke, hemorrhagic stroke, the cause and their clinical features, risk factors, and management etc.

什么是中风？

中风被定义为年代yndrome of rapid onset of the cerebral deficit which is lasting for more than 24 hours or leading to death with no cause apparent other than a vascular one. In a stroke the blood supply to the brain is compromised and depending on the way this happens, strokes have been classified into two subcategories as ischemic and hemorrhagic strokes.

Ischemic Stroke

An ischemic stroke is the impairment of the blood supply to brain secondary to an obstruction in a cerebral vessel. A vast majority of the strokes are ischemic strokes.

Causes of Ischemic Stroke

• Thrombosis and embolism

Atrial fibrillation和心律不齐导致血栓形成及其随后的栓塞是中风的最常见原因。在不同血管区域的同时梗塞是心脏栓塞中风的明显迹象。

• 灌注不足
• 大动脉狭窄
• Small vessel disease

缺血性中风的临床特征

• There are loss motor control and sensation over different regions of the body depending on the area of the brain that is affected.
• 视觉变化和缺陷
• Dysarthria
• 意识丧失
• 面部下垂

Hemorrhagic Stroke

在出血性中风中，对大脑的血液供应受损是由于对血管或血管的损害。血管与动脉瘤和weak walls are more susceptible to get ruptured and give rise to hemorrhages inside the cranial cavity.

Causes of Hemorrhagic Stroke

• Intracerebral hemorrhages
• Subarachnoid hemorrhages

These hemorrhages can be due to trauma, rupturing of aneurysms, arteriovenous malformations and etc.

Clinical Features of Hemorrhagic Stroke

临床特征将与缺血性出血相似。此外，亚蛛网膜下腔出血也会引起以下一组体征和症状。

• 年代udden onset of a severe headache
• 恶心
• vomiting
• 年代yncope
• 畏光

Risk factors for strokes

• 高血压
• Chronic smoking
• Sedentary and stressful lifestyle
• Chronic酗酒
• High cholesterol
• Atrial fibrillation
• Obesity
• Diabetes
• Sleep apnea
• Carotid stenosis

中风的管理

• The patient should be immediately admitted to a multidisciplinary care unit.

必须采取以下一般措施，

• Confirm the patency of the airway and continue monitoring it to identify any obstructions in it
• 通过口罩提供氧气，监测血压
• 尝试识别栓子的来源
• 评估患者吞咽的能力

脑成像是评估损害程度和可能原因的必要条件。CT和MRIare the most appropriate imaging modalities. If the radiographs show the presence of a hemorrhage, avoid giving any drug that can interfere with clotting. If there is no hemorrhage and thrombolysis is not contraindicated start the thrombolytic therapy immediately.

在出血的情况下，有时需要进行神经外科手术来耗尽颅腔内积聚的血液，并防止会堆积不适当的压力，以压缩脑物质。

在中风患者的长期管理中，应确定上述危险因素，并应采取措施来最大程度地减少患者生命的风险。抗高血压疗法和抗凝治疗（尤其是在心房颤动患者中）是中风患者长期治疗的两个重要方面。心理治疗和物理疗法将有助于改善患者的生活质量。

What is CVA?

CVA或脑血管事故是中风的医疗名称。

CVA和中风有什么区别？

• There is no difference between CVA and Stroke. CVA and stroke are synonyms that in general terms mean the appearance of various neurological deficits as a result of the vascular lesions in the brain.

概括– CVAvs中风

中风被定义为年代yndrome of rapid onset of the cerebral deficit which is lasting for more than 24 hours or leading to death with no cause apparent other than a vascular one. CVA or cerebrovascular accident is the medical name given to strokes. Thus, there is no difference between CVA and Stroke since they both indicate the same thing.
