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]
A false aneurysm, or pseudoaneurysm, is a collection of blood leaking completely out of an artery or vein but confined next to the vessel by the surrounding tissue. This blood-filled cavity will eventually either thrombose (clot) enough to seal the leak or rupture out of the surrounding tissue.
Rasmussen aneurysm is a distinctive variant of pseudoaneurysm of a branch of the pulmonary artery, predominantly found adjacent to or within a lung cavity, both often arising as a complication of pulmonary tuberculosis. [1] [2] The condition was originally described by Fritz Valdemar Rasmussen in 1868. [3]
Ventricular aneurysms are one of the many complications that may occur after a heart attack.The word aneurysm refers to a bulge or 'pocketing' of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum, or within the aorta.
These are pseudoaneurysm, caused by thrombus clogging the distal arteries, which results in inflammation and small tears at the site of occlusion. These inflammation and thrombis can caused by infective endocarditis , artificial heart valve or other heart problems.
Intradural pseudoaneurysm is a broad term to describe several subtypes of aneurysms that fundamentally are different from the more typical intracranial berry-type aneurysms. References [ edit ]
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.
The majority of individuals suffering from coronary artery aneurysms do not exhibit any symptoms; the development of complications or concurrent atherosclerotic coronary artery disease is what causes clinical manifestations to occur.
