A pseudoaneurysm, also known as a false aneurysm, is a locally contained hematoma outside an artery or the heart due to damage to the vessel wall. [1] The injury passes through all three layers of the arterial wall, causing a leak, which is contained by a new, weak "wall" formed by the products of the clotting cascade. [1]
Risk factors for an aneurysm include diabetes, obesity, hypertension, tobacco use, alcoholism, high cholesterol, copper deficiency, increasing age, and tertiary syphilis infection. [20]: 602 Connective tissue disorders such as Loeys-Dietz syndrome, Marfan syndrome, and certain forms of Ehlers-Danlos syndrome are also associated with aneurysms ...
The dilation of the pulmonary artery in close proximity to or involvement within the lung cavity leads to the formation of a pseudoaneurysm. [2] [4] As is typical with any aneurysm, Rasmussen aneurysm carries the inherent risk of rupture, which may result in life-threatening massive hemoptysis, characterized by the coughing of blood. Such ...
People with symptoms suggestive of thoracic aortic dissection should be routinely evaluated "to establish a pretest risk of disease that can then be used to guide diagnostic decisions." People diagnosed with Marfan syndrome should immediately have an echocardiogram to measure the aorta and followed up six months later to check for aortic ...
Risk factors include cigarette smoking, extreme alcoholism, advanced age, dyslipidemia, hypertension, and coronary artery disease. [4] The pathophysiology of the disease is related to an initial arterial insult causing a cascade of inflammation and extracellular matrix protein breakdown by proteinases leading to arterial wall weakening. [ 5 ]
These are less common than abdominal aneurysms. Small aneurysms generally pose no threat. However, aneurysms increase the risk for: [citation needed] Atherosclerotic plaques to form at the site of the aneurysm, which causes further weakening of the artery wall. blood clots may form at the site and dislodge, increasing the chance of stroke
An estimated 0.67% of patients admitted to the hospital after major motor vehicle accidents were found to have blunt carotid injury, including intimal dissections, pseudoaneurysms, thromboses, or fistulas. [20] Of these, 76% had intimal dissections, pseudoaneurysms, or a combination of the two.
Virchow's triad or the triad of Virchow (/ ˈ f ɪər k oʊ /) describes the three broad categories of factors that are thought to contribute to thrombosis. [1] Hypercoagulability; Hemodynamic changes (stasis, turbulence) [2] Endothelial injury/dysfunction; It is named after the renowned German physician Rudolf Virchow (1821–1902). However ...
