Aneurysms May Recur Years after Endovascular Treatment

RSNA: Endovascular treatment (EVT) of intracranial aneurysm is effective in preventing long-term bleeding, but may be followed by aneurysm recurrences in a significant proportion of cases, according to a new magnetic resonance angiography (MRA) study published online in the journal Radiology. Intracranial aneurysm is a weak or thin spot in a blood vessel in the brain that balloons and fills with blood. It can leak or rupture, leading to a potentially fatal cerebral hemorrhage.

Surgery for small abdominal aortic aneurysms that do not cause symptoms

Cochrane: An aneurysm is a ballooning of an artery (blood vessel), which, in the case of an abdominal aortic aneurysm (AAA), occurs in the major artery in the abdomen (aorta). Ruptured AAAs cause death unless surgical repair is rapid, which is difficult to achieve. Surgery is considered necessary for people with aneurysms of more than 5.5 cm in diameter or who have associated pain, to relieve symptoms and to reduce the risk of rupture and death. However, risks are associated with surgery. Surgical repair consists of insertion of a prosthetic inlay graft, either by open surgery or endovascular repair.

An aneurysm is a balloon-like bulge in an artery. Arteries are blood vessels that carry oxygen-rich blood to your body.
Arteries have thick walls to withstand normal blood pressure. However, certain medical problems, genetic conditions, and trauma can damage or injure artery walls. The force of blood pushing against the weakened or injured walls can cause an aneurysm.
An aneurysm that occurs in the abdominal portion of the aorta is called an abdominal aortic aneurysm (AAA).

Aortic aneurysm

Aortic aneurysm, also called: AAA, TAA is a bulge or "ballooning" in the wall of the aorta, the main artery that runs from the heart through the chest and abdomen.. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death.
There are two types of aortic aneurysm:

• Thoracic aortic aneurysms - these occur in the part of the aorta running through the chest
• Abdominal aortic aneurysms - these occur in the part of the aorta running through the abdomen

Most aneurysms are found during tests done for other reasons. Some people are at high risk for aneurysms. It is important for them to get screening, because aneurysms can develop and become large before causing any symptoms Screening is recommended for people between the ages of 65 and 75 if they have a family history, or if they are men who have smoked. Doctors use imaging tests to find aneurysms. Medicines and surgery are the two main treatments.
