Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream (embolism). [ 6 ] Symptoms of a PE may include shortness of breath, chest pain particularly upon breathing in, and coughing up blood. [ 1 ] Symptoms of a blood clot in the leg may also be present, such ...
Hypercoagulability in pregnancy is the propensity of pregnant women to develop thrombosis (blood clots). Pregnancy itself is a factor of hypercoagulability (pregnancy-induced hypercoagulability), as a physiologically adaptive mechanism to prevent post partum bleeding. [1] However, when combined with an additional underlying hypercoagulable ...
An amniotic fluid embolism (AFE) is a life-threatening childbirth (obstetric) emergency in which amniotic fluid enters the blood stream of the mother, triggering a serious reaction which results in cardiorespiratory (heart and lung) collapse and massive bleeding (coagulopathy). [1][2][3] The rate at which it occurs is 1 instance per 20,000 ...
The black areas on either side are the lungs, with around it the chest wall. A CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. Its main use is to diagnose pulmonary embolism (PE). [1] It is a preferred choice of imaging in the diagnosis of ...
Deep vein thrombosis (DVT) is a type of venous thrombosis involving the formation of a blood clot in a deep vein, most commonly in the legs or pelvis. [ 9 ][ a ] A minority of DVTs occur in the arms. [ 11 ] Symptoms can include pain, swelling, redness, and enlarged veins in the affected area, but some DVTs have no symptoms.
Having a first DVT (deep vein thrombosis) or PE (pulmonary embolism) before age 50. Having recurring DVT or PE. Having venous thrombosis in unusual sites in the body such as the brain or the liver. Having a DVT or PE during or right after pregnancy. Having a history of unexplained pregnancy loss in the second or third trimester.
OPS-301 code. 3-703.2. [edit on Wikidata] A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, [1][2] in order to determine the ventilation/perfusion ratio ...
In fact, it was not until decades after Virchow's death that a consensus was reached proposing that thrombosis is the result of alterations in blood flow, vascular endothelial injury, or alterations in the constitution of the blood. Still, the modern understanding of the factors leading to embolism is similar to the description provided by Virchow.
