Mycotic aneurysm develops after an infection (typically in your heart valves) has weakened an artery wall. An aneurysm in the brain (also called a cerebral aneurysm or an intracranial aneurysm) is a bulging, weakened area in the middle layer of the wall of a blood vessel in the brain, resulting in an abnormal widening. Approximately 90% of cerebral (brain) aneurysms are saccular aneurysms, according to the Columbia University Department . Design Observational surveillance study. The three types of cerebral aneurysms are: berry (saccular), fusiform and mycotic. The three different types of aneurysms: Fusiform, saccular, and pseudoaneurysm. This type of aneurysm is rounded and hangs from the artery as a berry hangs from a vine. The dye makes the blood vessels visible on an X-ray. An aneurysm may occur in any artery, but is often seen in arteries in the brain. Classification of Aortic Aneurysm (According to Location) Ascending Aortic Aneurysm(Annuloaortic ectasia Aortic Arch .

Background The Raymond-Roy Occlusion Classification (RROC) is the standard for evaluating coiled aneurysms (Class I: complete obliteration; Class II: residual neck; Class III: residual aneurysm), but not all Class III aneurysms behave the same over time. A cerebral or intracranial aneurysm is an abnormal focal dilation of an artery in the brain that results from a weakening of the inner muscular layer (the intima) of a blood vessel wall. Congenital- Tuberous sclerosis, aortic coarctation, Marfan's. Crawford Aneurysm Type Assessing the AAA patient Normal - aorta 1-2.4cm & iliac 0.6-1.2cm Aneurysm - Aorta >3cm & iliac > 2cm RF for aneurysm Older age, male gender, white race, positive family history, smoking, HTN, hypercholesterolemia, PVD, CAD. Background: Treatment of perforator involving aneurysm (piAN) remains a challenge to open and endovascular neurosurgeons. If an aneurysm ruptures, then pain, low blood pressure, a rapid heart rate, and lightheadedness may occur. Abdominal Aortic Aneurysm Abdominal aortic aneurysms, sometimes known as "Triple A," are the most common aneurysms of the aorta the large blood vessel that carries blood away from your heart and through your body.
