Blood leaking from the vessel collects in surrounding tissue. It is sometimes called a false aneurysm. It also may be called pseudoaneurysm of the vessels. In a true aneurysm, the vessel wall weakens and bulges. It sometimes forms a blood-filled sac. But the vessel wall is not injured.

What Is a Pseudoaneurysm? A pseudoaneurysm, also called a false aneurysm, results from an injury to your blood vessel wall (usually an artery). Blood pools in a small sac attached to one side of your artery. Unlike an aneurysm, a pseudoaneurysm only includes one …

2024年2月17日 · Pseudoaneurysms are false aneurysms occurring at the site of arterial injury from trauma or infection. Unlike true aneurysms in which the blood vessel wall balloons, a pseudoaneurysm does not involve the vascular wall. Instead, blood leaks from the injury site and is contained by a wall developed with the products of the clotting cascade.

2019年12月13日 · As you might guess from the name, a pseudoaneurysm is a false aneurysm. It occurs when the wall of a blood vessel is damaged. This can cause blood to leak out of the blood vessel and to...

2024年8月7日 · What Is a Pseudoaneurysm? A pseudoaneurysm happens as a result of injury to a blood vessel. The artery leaks blood, which then pools near the damaged spot. It's different from a true aneurysm,...

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]

2024年8月8日 · False aneurysms, also known as pseudoaneurysms, are abnormal outpouchings or dilatation of arteries which are bounded only by the tunica adventitia, the outermost layer of the arterial wall. These are distinguished from true aneurysms, which are bounded by all three layers of the arterial wall.

A pseudoaneurysm, also termed a false aneurysm, is a leakage of arterial blood from an artery into the surrounding tissue with a persistent communication between the originating artery and the resultant adjacent cavity.

2024年12月27日 · A pseudoaneurysm occurs when blood leaks out of a damaged blood vessel but is contained by the surrounding tissues, forming a blood-filled sac. Unlike a true aneurysm, which involves all layers of the vessel wall, pseudoaneurysms lack an intact vessel wall.

2023年3月16日 · A pseudoaneurysm, also known as a “false aneurysm”, occurs when there is a breach to the arterial wall, resulting in an accumulation of blood between the tunica media and tunica adventitia of the artery.
