In Medicine

An embolism occurs when an object (the embolus, plural emboli) migrates from one part of the body (through circulation) and cause(s) a blockage (occlusion) of a blood vessel in another part of the body. The term was coined in 1848 by Rudolph Carl Virchow.^[1] For other uses, see Body (disambiguation). ... For transport in plants, see Vascular tissue. ... A term indicating that the state of something, which is normally open, is now totally closed. ... f you all The blood vessels are part of the circulatory system and function to transport blood throughout the body. ... Dr. R.L.K. Virchow Rudolf Ludwig Karl Virchow (born October 13, 1821, in Schivelbein (Pomerania); died September 5, 1902, in Berlin) was a German doctor, anthropologist, public health activist, pathologist, prehistorian, biologist and politician. ...

This can be contrasted with a "thrombus" which is the formation of a clot within a blood vessel, rather than being carried from somewhere else. Thrombus mainly form in the Arteries whereas Emboli form in the Veins. Blood clot diagram. ... Coagulation is the thickening or congealing of any liquid into solid clots. ... Section of an artery For other uses, see Artery (disambiguation). ... In the circulatory system, a vein is a blood vessel that carries blood toward the heart. ...

Blood clots form the most common embolic material by far: other possible embolic materials include fat globules (a fat embolism), air bubbles (an air embolism), talc embolism (often following drug abuse), septic emboli (containing pus and bacteria), or amniotic fluid. Human blood smear: a - erythrocytes; b - neutrophil; c - eosinophil; d - lymphocyte. ... For other uses, see FAT. Fats consist of a wide group of compounds that are generally soluble in organic solvents and largely insoluble in water. ... A fat embolism is a type of embolism that is often (but not always) caused by physical trauma. ... Look up air in Wiktionary, the free dictionary. ... An air embolism, or more WITCH generally gas embolism, is a medical condition caused by gas bubbles in the bloodstream (embolism in a medical context refers to any large moving mass or defect in the blood stream). ... Pus is a whitish-yellow or yellow substance produced during inflammatory responses of the body that can be found in regions of pyogenic bacterial infections. ...

The amniotic sac is a tough but thin transparent pair of membranes which holds a developing embryo (and later fetus) until shortly before birth. ...

Emboli often have more serious consequences when they occur in the so-called "end-circulation": areas of the body that have no redundant blood supply, such as the brain, heart, and lungs. For other uses, see Brain (disambiguation). ... The heart and lungs, from an older edition of Grays Anatomy. ... Pulmonary embolism (PE) is blockage of the pulmonary artery (or one of its branches) by a blood clot, fat, air or clumped tumor cells. ...

Assuming a normal circulation, a thrombus or other embolus formed in a systemic vein will always impact in the lungs, after passing through the right side of the heart. This forms a pulmonary embolism that can be a complication of deep-vein thrombosis. Note that, contrary to popular belief, the most common site of origin of pulmonary emboli are the femoral veins, not the deep veins of the calf. Deep veins of the calf are the most common site of thrombi, not emboli origin. In the circulatory system, a vein is a blood vessel that carries blood toward the heart. ... DVT can also refer to Driving Van Trailer Deep venous thrombosis (or DVT) is the occlusion of a deep vein by a blood clot (thrombus). It generally affects the leg veins, such as the femoral vein or the popliteal vein, or occasionally the veins of the arm (Paget-von Schroetter... Grays Fig. ...

Some congenital abnormalities of the circulation, especially septal defects (holes in the cardiac septum), allow an embolus from a systemic vein to cross into the arterial system and land anywhere in the body. The most common such abnormality is patent foramen ovale, occurring in about 25 % of the adult population, but here the defect functions as a valve which is normally closed, because pressure is slightly higher in the left side of the heart. In certain circumstances, e.g. if patient is coughing just when an embolus is passing, passage to the arterial system may occur. An atrial septal defect (ASD) is a group of congenital heart diseases that involve the inter-atrial septum of the heart. ...

Emboli starting in the heart (from a thrombus in the left atrium secondary to atrial fibrillation or septic emboli from endocarditis) can cause emboli in any part of the body. Anterior (frontal) view of the opened heart. ... Atrial fibrillation (AF or afib) is a cardiac arrhythmia (abnormal heart rhythm) that involves the two upper chambers (atria) of the heart. ... Endocarditis is an inflammation of the inner layer of the heart, the endocardium. ...

An embolus landing in the brain from either the heart or a carotid artery will likely cause an ischemic stroke. For other uses, see Brain (disambiguation). ... The heart and lungs, from an older edition of Grays Anatomy. ... In human anatomy, the carotid artery is a major artery of the head and neck. ... For other uses, see Stroke (disambiguation). ...

Emboli of cardiac origin are also frequently encountered in clinical practice. Thrombus formation within the atrium in valvular disease occurs mainly in patients with mitral valve disease, and especially in those with mitral valve stenosis with atrial fibrillation (AF). In the absence of AF, pure mitral regurgitation has low incidence of thromboembolism. Absolute risk of emboli in idiopathic AF depends on other risk factors such as increasing age, hypertension, diabetes, recent heart failure, or previous stroke. Thrombus formation can also take place within the ventricles, and it occurs in approximately 30% of anterior wall myocardial infarctions, compared to only 5% of inferior ones. Other risk factors include poor ejection fraction (<35%), size of infarct, as well as presence of AF. In the first three months after infarction, left ventricle aneurysms have 10% risk of embolization. Patients with prosthetic valves also carry a significant increase in risk of thromboembolism. Risk varies on the valve type (bioprosthetic or mechanical), the positon (mitral or aortic), and presence of other factors such as AF, left ventricular dysfunction, previous emboli, etc. The heart and lungs, from an older edition of Grays Anatomy. ... The mitral valve (also known as the bicuspid valve or left atrioventricular valve), is a dual flap (bi = 2) valve in the heart that lies between the left atrium (LA) and the left ventricle (LV). ... The mitral valve (also known as the bicuspid valve or left atrioventricular valve), is a dual flap (bi = 2) valve in the heart that lies between the left atrium (LA) and the left ventricle (LV). ... A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure. ... Atrial fibrillation (AF or afib) is a cardiac arrhythmia (abnormal heart rhythm) that involves the two upper chambers (atria) of the heart. ... Idiopathic means arising spontaneously or from an obscure or unknown cause. ... For other forms of hypertension, see Hypertension (disambiguation). ...
