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

Introduction: I am going to discuss hemiplegia. The word ’plegia’ means weakness so severe that it is nearly complete. ’Hemi’ implies one side of the body. Hence‚ ’hemiplegia’ means complete paralysis of one half of the body‚ including one arm and leg. Any disease or injury in the motor centers of the brain can cause hemiplegia. Hemiplegia is a more severe form of ’hemiparesis’ wherein one half of the body is only weakened. It is also very different from the conditions of paraplegia & quadriplegia

Bruce’s right leg. (4 marks) Deep vein thrombosis refers to the formation of a blood clot in a deep vein in the leg. Deep vein thrombosis tends to occur in leg veins‚ such as the popliteal or femoral veins‚ as well as deep veins within the pelvis. The blocked vein in Bruce’s right led caused edema and led to tissue ischemia. Edema developed inferior to the blocked vein. Blockage of the vein increased the capillary hydrostatic pressure increased the amount of fluid that flowed from the capillaries

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
