The pulmonary embolism rule-out criteria (PERC) helps assess people in whom pulmonary embolism is suspected, but unlikely. Unlike the Wells score and Geneva score , which are clinical prediction rules intended to risk stratify people with suspected PE, the PERC rule is designed to rule out the risk of PE in people when the physician has already ...
In detailing the pathophysiology surrounding pulmonary embolism, he alluded to many of the factors known to contribute to venous thrombosis. While these factors had already been previously established in the medical literature by others, [ 10 ] [ 11 ] for unclear reasons they ultimately became known as Virchow's triad.
deep vein thrombosis (DVT) [3] [4] [5] BD71, pulmonary embolism (PE) [3] [4] [5] BB00. VTE is a common cardiovascular disorder with significant morbidity and mortality. [3] [4] [5] VTE can present with various symptoms, such as painful leg swelling, chest pain, dyspnea, hemoptysis, syncope, and even death, depending on the location and extent ...
Wells attended the University College, Toronto for his undergraduate degree in 1978. While there, he competed on the varsity track and field team and placed second in the Canadian Senior Track and Field Championships/1982 Commonwealth Games Trials meeting the Olympic standard of 2.18 metres that year.
He coined the terms embolism (initially called "Embolia") and thrombosis while proposing a hypothesis for the pathophysiology of pulmonary thromboembolism. [5] [12] In his work, he described the consequences of thrombosis and the factors leading thereto, a concept which today is known as Virchow's Triad. However, there is some dispute regarding ...
A venous embolus (mostly from deep vein thrombosis in the lower limbs) will travel through the systemic circulation, reach the right side of the heart, and travel through the pulmonary artery, resulting in a pulmonary embolism. Arterial thrombosis resulting from hypertension or atherosclerosis can become mobile and the resulting emboli can ...
Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term disease caused by a blockage in the blood vessels that deliver blood from the heart to the lungs (the pulmonary arterial tree). These blockages cause increased resistance to flow in the pulmonary arterial tree which in turn leads to rise in pressure in these arteries ...
Jugular vein thrombosis is a condition that may occur due to infection, intravenous drug use or malignancy. Jugular vein thrombosis can have a varying list of complications, including: systemic sepsis, pulmonary embolism, and papilledema. Though characterized by a sharp pain at the site of the vein, it can prove difficult to diagnose, because ...
