calf muscle pump overcomes this‚ which in turn can return the blood to the heart (Hirsch 1994). Laminar flow is also interfered with by clot formation. This promotes thrombus formation by bringing platelets into contact with the endothelium. Endothelial injury to blood vessels from a variety of sources is the most common cause of thrombus formation as stated by Cotran et al 1999. Porth 2005 goes on to explain that the endothelial layer provides a smooth and slippery inner surface for the vessel‚ which

embolism causes an obstruction or occlusion of the pulmonary artery or one of its branches‚ which in turn reverts pressure on the right ventricle. A solid embolus can be a thrombus‚ also known as a blood clot‚ which traveled through the circulation to cause obstruction or occlusion in a location distant from its origin. A thrombus is always a solid‚ non-traveling stationary body that causes obstruction

appendages. The first main branch of the internal carotid is the ophthalmic artery which further branches into the central retinal artery. If the patient was known to have a partial obstruction on the right carotid artery 2 years ago‚ we can assume a thrombus which originated from this obstruction was later lodged downstream causing the stroke in the right hemisphere. It is also evident that the partial obstruction in the internal carotid became further constricted overtime because of the buildup of plaque

constricted. The reparative coagulum is initiated as platelets adhere to the interior surfaces of the vessels as well as to a newly forming matrix of fibrin that together become the cruor of the thrombus‚ thus forming a provisional wound matrix. Together with the dehydration of surface bodily fluids‚ the thrombus and the scab decrease microvascular permeability. 2.

(Microsoft Encarta‚ 2004). ETIOLOGY The most common cause of acute myocardial infarction (AMI) is complete or nearly complete occlusion of a coronary artery usually precipitated by rupture of the vulnerable atherosclerotic plaque and subsequent thrombus formation. Plaque rupture can be precipitated by both internal and external factors. Internal factors include plaque characteristics‚ such as the size and consistency of the lipid core and the thickness of the fibrous cap‚ as well ac conditions

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. Each year alone about 150‚000 people in America die from a stroke or are seriously disabled. Stroke

There are many risk factors associated with stroke. The more risk factors a person has‚ the greater the chance that he or she will have a stroke. Some of these you have no control of‚ such as increasing age‚ family health history‚ race and gender. But you can change or treat most other risk factors to lower your risk. The chance of having a stroke more than doubles every decade after the age of 55. The chance is greater in people who have a family history of stroke. African Americans have a much
