What is systemic thromboembolism?
Systemic embolism Part 11 of 16 Definition – emboli which travel through the systemic arterial circulatory system. The vast majority of these arise within the heart secondary to atrial fibrillation (altered flow) or thrombus formation over an area of myocardial infarction (altered wall).
What causes systemic thromboembolism?
Damage to the arteries by disease or other health conditions is one major cause. High blood pressure may also increase the risk of an embolism. Having high blood pressure weakens the arterial walls, making it easier for blood to accumulate in the weakened artery and form clots.
What is embolism PPT?
1. EMBOLISM Dr. Deepak K. Gupta. Introduction • process of partial or complete obstruction of some part of the cardiovascular system by any mass carried in the circulation; • transported intravascular mass detached from its site of origin is called an embolus • emboli (90%) are thromboemboli.
What is DVT PPT?
Deep vein thrombosis is a part of a condition called venous thromboembolism. Deep vein thrombosis occurs when a blood clot (thrombus) forms in one or more of the deep veins in the body, usually in the legs. Deep vein thrombosis can cause leg pain or swelling, but may occur without any symptoms.
What is the difference between thrombosis and embolism?
A thrombus is a blood clot that forms in a vein. An embolus is anything that moves through the blood vessels until it reaches a vessel that is too small to let it pass. When this happens, the blood flow is stopped by the embolus.
What is DVT in calf?
Deep vein thrombosis (DVT) is a blood clot that develops within a deep vein in the body, usually in the leg. Blood clots that develop in a vein are also known as venous thrombosis. DVT usually occurs in a deep leg vein, a larger vein that runs through the muscles of the calf and the thigh.
What is embolus and thrombus?
A thrombus is a blood clot that forms in a vein. An embolus is anything that moves through the blood vessels until it reaches a vessel that is too small to let it pass. When this happens, the blood flow is stopped by the embolus. An embolus is often a small piece of a blood clot that breaks off (thromboembolus).
Which is the example liquid emboli?
The embolus may be a blood clot (thrombus), a fat globule (fat embolism), a bubble of air or other gas (gas embolism), amniotic fluid (amniotic fluid embolism), or foreign material. An embolism can cause partial or total blockage of blood flow in the affected vessel.
What is pulmonary thromboembolism?
Pulmonary Thromboembolism Dr. Rikin Hasnani 2nd Year PG Dept of Pulmonary Medicine 2. Introduction • Pulmonary thromboembolic disease refers to the condition in which thrombus or multiple thrombi migrate from the systemic circulation to the pulmonary vasculature.
How do you classify thrombotic emboli?
Classification • Depending upon the matter in the emboli – Solid: detached thrombi (thromboemboli), atheromatous material, tumour cell clumps, tissue fragments, parasites, bacterial clumps, foreign bodies. – Liquid: fat globules, amniotic fluid, bone marrow.
What is the prognosis of pulmonary thromboembolism?
Pulmonary Thromboembolism: Consequences • Resolution: Vast majority of small pulmonary emboli (60-80%) are resolved by fibrinolytic activity • Acute cor pulmonale – Numerous small emboli may obstruct most of the pulmonary circulation resulting in acute right heart failure.
What are the different types of embolism?
– Arterial emboli : systemic arteries in the brain, spleen, kidney, intestine – Venous emboli: pulmonary arteries. – Lymphatic emboli can also occur. 4. Thromboembolism • A detached thrombus or part of thrombus constitutes the most common type of embolism.
