A pseudoaneurysm, or blood vessel pseudoaneurysm, occurs when the wall of a blood vessel is injured and leaking blood collects in the surrounding tissue. It is sometimes called a false aneurysm.

What is the difference between aneurysm and pseudoaneurysm?
False aneurysms are ruptures of the arterial wall that are contained between the adventitia or the perivascular tissues1,2. Pseudoaneurysms are usually the result of direct trauma, inflammation, or infection in the wall.
What is a true aneurysm?
We speak of a true aneurysm when all three arterial walls (intima, media and adventitia) are affected. In the fusiform subtype there is a symmetrical dilatation of the entire circumference, while in the saccular there is a more localized dilatation, similar to an evagination3.
How is a pseudoaneurysm treated?
Small pseudoaneurysms may clot spontaneously, but definitive treatment is sometimes needed. Surgery has traditionally been considered the gold standard treatment, although it is not risk-free in patients with severe cardiovascular disease.
What types of aneurysms are there?
There are three types of aneurysms in the aorta:
- Fusiform: affects the entire contour of the aorta. … Saccular: it is asymmetric, only part of the contour of the aorta is dilated. Pseudoaneurysm: the inner layer of the aortic wall and a lateral dilation of the outer layer is produced.

What is the most common type of aneurysm?
The most common is called a sacciform aneurysm. This type can vary in size from a few millimeters to more than a centimeter. Giant sacciform aneurysms can exceed 2.5 cm. These aneurysms are more common in adults.
How are brain aneurysms classified?
The three types of cerebral aneurysms are: saccular, fusiform, and mycotic. Saccular aneurysm is the most common in adults. It can vary in size from a few millimeters to more than two centimeters. A family history of aneurysms can increase the risk.
What is cystic necrosis?
Medial degeneration (DM), frequently called cystic medial necrosis, is a histopathological finding commonly present in the wall of aortic aneurysms1,2,9.
What is a femoral aneurysm?
A superficial femoral artery aneurysm is defined as a dilation of 2 or more centimeters in diameter. It occurs more frequently in male patients in 95% and with a mean age of 75 years with ranges from 61 to 91 years2.
What is a dissecting aortic aneurysm?
A dissecting aneurysm of the aorta is called a blood collection that appears in the middle layer of the aorta, with rupture of the intima and that produces a sleeve dissection that progresses along the arterial trunk.
What organs does the aneurysm affect?
If an aneurysm grows, it can rupture and cause dangerous bleeding and even death. Most aneurysms occur in the aorta, the main artery that leaves the heart and passes through the chest and abdomen. They can also occur in the arteries of the brain and other parts of the body.
How is death by aneurysm?
Death occurs due to rapid and severe bleeding in the brain. Ruptured brain aneurysms cause death in about 40 percent of patients. Of those patients who survive, nearly half will have some form of permanent disability.
How long can you live with a brain aneurysm?
Short-term mortality is between 8.7% one week after treatment, during the hospitalization period, and 18.4% after three months. One year after the vascular accident, it reaches 22.9% and five years later, 29%.
Why does an aneurysm occur?
Brain aneurysms form as a result of thinning of the arterial walls. Aneurysms often form at the forks or branches of arteries because those sections of the blood vessel are weaker.
What happens when the arteries in the legs get clogged?
It is a condition of the blood vessels that supply the legs and feet. This occurs because of narrowing of the arteries in the legs. This causes decreased blood flow, which can damage nerves and other tissues.
What artery runs through the right leg?
The femoral artery is labeled above and to the right.
What is necrosis and how does it occur?
It is the death of body tissue. It occurs when too little blood flows to the tissue. This can happen from injury, radiation, or chemicals.
What is necrosis and examples?
Necrosis is defined as the pathological death of a set of cells or any tissue in the body, due to a harmful agent that has caused such a serious injury that it cannot be repaired or cured; for example, insufficient blood supply to the tissue or ischemia, or trauma1,2.
How to remove necrosis?
Options include the following:
Core decompression. The surgeon removes part of the inner layer of the bone. … Bone transplant (graft). … Bone restructuring (osteotomy). … Joint replacement. … Regenerative medicine treatment.
How are aneurysms classified morphologically?
The classification of a cerebral aneurysm, according to its morphology, corresponds to 3 basic categories: saccular aneurysm, fusiform aneurysm and. dissecting aneurysm.
Where are aneurysms most common?
Defects in some of the parts of the arterial wall may be responsible. Common locations for aneurysms include: The major artery leading from the heart, such as the abdominal or thoracic aorta. The brain (cerebral aneurysm)
What happens if a brain aneurysm is not operated on?
Brain aneurysm is worrisome because if it tears or ruptures, it causes bleeding in or around the brain which is known as a hemorrhagic stroke. A burst aneurysm can quickly become life-threatening, and therefore warrants immediate medical treatment.
How are brain aneurysms cured?
Brain aneurysms can be treated surgically or with an endovascular approach – approximately 50 percent of aneurysms are treated with endovascular procedures, without the need for direct surgery.
How is a person after a brain aneurysm?
You may feel tired for up to 12 weeks or more. If you had a stroke or brain injury from the bleeding, you may have permanent problems such as speech problems, trouble thinking, muscle weakness, or numbness.
What is an aneurysm headache like?
The main symptoms of a brain aneurysm are a sudden and very intense headache, which can often be confused with a migraine, as well as stiffness in the cervical area of the neck. For this reason, many patients receive a migraine or cervical contracture as their first diagnosis.
