A pseudoaneurysm or a false aneurysm is a hematoma that forms outside the wall of an artery, due to a leaking hole in the artery. This is different from a true aneurysm which is a collection of blood between the layers of the arterial walls.
Small pseudoaneurysms may clot spontaneously, while others require treatment.
Surgery is often recommended in these cases. A non-invasive treatment is Ultrasound Guided Compression or UGC, which is technically simple and cost effective. This is a technique to manually compress the hematoma.
Percutaneous thrombin injection, given under sonographic guidance are also used to compress the pseudoaneurysms and achieve thrombosis of the blood. Thrombin is a potent, natural coagulant.
aneurysms
Aneurysms that occur in the part of the aorta within the abdomen are called abdominal aortic aneurysms.
Vasculitis can lead to aneurysms
Endovascular embolization is a procedure that utilizes chemical agents or metallic coils to stop bleeding and treat aneurysms or brain tumors.
Small aneurysms should be monitored for their rate of growth and large aneurysms require consideration for a surgical repair.
Aortic aneurysms are potentially life-threatening conditions.
Cerebral aneurysms are usually aneurysms we are born with. There are certain conditions, however, that can predispose one to develop aneurysms later in life. Hypertension can cause small aneurysms in the brain stem and midbrain that can bleed - these usually are not able to be seen because they are so small, however. Another possible cause is infections. These aneurysms are called mycotic aneurysms and are the result of infectious material, or emboli, being lodged in the cerebral arteries, causing a localized infection and weakening of the artery walls, leading to aneurysmal formation.
Aneurysms can occur in any artery of the body. The three most common and the main areas of concern for aneurysms to occur are the brain, abdominal aorta, and the femoral artery.
medical researchers estimate that 1-5% of the population has some type of cerebral aneurysm. Aneurysms rarely occur in the very young or the very old; about 60% of aneurysms are diagnosed in people between ages 40 and 65.
