Causes of acquired cerebrovascular disease include atherosclerosis, embolism, aneurysms, and arterial dissections. [9] Atherosclerosis leads to narrowing of blood vessels and less perfusion to the brain, and it also increases the risk of thrombosis, or a blockage of an artery, within the brain.
Stroke is a medical condition in which poor blood flow to a part of the brain causes cell death. [5] There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. [5]
CVA tenderness is also present in patients who have retrocecal appendicitis and retroperitoneal abscesses. [4] In patients with sickle cell disease, blockage of blood flow to the kidney may cause CVA tenderness. [4] A lack of CVA tenderness in patients with low back pain supports a diagnosis other than kidney pathology. [7]
Strokes or heart attacks cause more than 80% of cardiovascular disease deaths. Both of these conditions are strongly linked to lifestyle habits. ... Strokes are a type of cerebrovascular disease ...
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Watershed strokes are caused by ischemia or a lack of blood flow to the brain. [2] There are several causes of ischemia, including embolism and atherosclerosis.There are several conditions that can predispose someone to watershed stroke by increasing the likelihood that insufficient blood supply will be able to reach the brain.
Cerebral amyloid angiopathy may cause intraparenchymal hemorrhage even in patients without elevated blood pressure. Unlike hypertension, cerebral amyloid angiopathy does not typically affect blood vessels to deep brain structures. Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2]
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
