A brain aneurysm is a weak spot or bulge in a brain blood vessel. It can happen to anyone at any age, but it's more common in people over age 40. Higher rates of aneurysms are seen in women than men, according to Web MD.

2009-06-19 An intracranial aneurysm, also known as a brain aneurysm, is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel.. Aneurysms in the posterior circulation (basilar artery, vertebral arteries and posterior communicating artery) have a higher risk of rupture. A cerebral aneurysm (also called an intracranial aneurysm or brain aneurysm) is a balloon like outpouching on the wall of artery secondary to wear and tear in most of the blood vessels and appears over the age of 50 years. Because there is a weakened spot in the artery wall, there is a risk for rupture (bursting) of the aneurysm. Results: Three hundred twenty-two saccular aortic aneurysms were identified in 284 patients.

Most thoracic and suprarenal saccular aneurysms can be repaired with a patch graft, which spares thoracic intercostals. berry aneurysm (brain aneurysm) a small saccular aneurysm of a cerebral artery, usually at the junction of vessels in the circle of Willis; such aneurysms frequently rupture, causing subarachnoid hemorrhage. Called also cerebral aneurysm. Abdominal aortic aneurysms are defined by a > 50% focal dilation of the abdominal aorta or when the abdominal aortic diameter is > 3 cm. 1-3 Aneurysms can be further classified into the more common fusiform subcategory (accounting for 80% of cases), or the rarer saccular type.

I have a 2.5 x 2.5 x 3.5 mm saccular aneurysm involving the mid cavernous left internal carotid artery oriented inferolaterally. This is located in an extradural location. I have no idea what any of this means!

AJNR Am J Neuroradiol 20:1309–1317, August 1999 Saccular Aneurysm Formation in Curved and Bifurcating Arteries George N. Foutrakis, Howard Yonas, and Robert J. Sclabassi BACKGROUND AND PURPOSE: Distinguishing whether forces resulting from the impinge- ment of central blood flow streams at a curved arterial segment or at the apex of an intracranial bifurcation could be important for the

More than 90% are located at one of the following five sites: (a) the internal carotid artery at the level of the posterior communicating artery; (b) the junction of the anterior cerebral and anterior communicating arteries; (c) the proximal bifurcation of the middle cerebral artery; (d) the junction of the posterior cerebral and basilar arteries, and (e) the bifurcation of the From analysis of these data we conclude that although saccular aortic aneurysms are rare, when present, they are most commonly found in the thoracic and suprarenal aorta. Most cases treated with surgery are symptomatic. Most thoracic and suprarenal saccular aneurysms can be repaired with a patch graft, which spares thoracic intercostals. Saccular aneurysms, or "berry" aneurysms, are spherical in shape and involve only a portion of the vessel wall; they usually range from 5 to 20 cm (2.0 to 7.9 in) in diameter, and are often filled, either partially or fully, by a thrombus. Methods: The literature was searched in Medline/Pubmed to identify extracranial in vivo saccular aneurysm models featuring growth and rupture, using a predefined search strategy in accordance with the PRISMA guidelines. From eligible studies we extracted the following details: technique and location of aneurysm creation, aneurysm pouch Rupture of a berry aneurysm, also known as a saccular aneurysm, usually results in a subarachnoid hemorrhage (SAH) but can, depending on the location of the rupture and presence of adhesions to the aneurysm, also result in cerebral hematoma, subdural hematoma and/or intraventricular hemorrhage.

The pain associated with an abdominal aortic aneurysm may be located in the abdomen, chest, lower back, or groin area. The pain may be severe or dull. Sudden, severe pain in the back or abdomen may mean the aneurysm is about to rupture.

Asymptomatic patients with aneurysm diameter <45 mm are managed with medical therapy and active surveillance. Saccular aortic aneurysm enlarges at a rate of 2.9 mm/year. Saccular Abdominal Aortic Aneurysms: Patient Characteristics, Clinical Presentation, Treatment, and Outcomes in the Netherlands.

Saccular aneurysm develops in the main renal artery at the bifurcation of the anterior and posterior divisions or at a branch point of a segmental artery. Although it is frequently calcified or shows atherosclerotic changes, it is usually regarded as congenital, the atherosclerosis being considered a secondary event.

Small aneurysms have a diameter of less than 15 mm. Larger aneurysms include those classified as large (15 to 25 mm), giant (25 to 50 mm), and super-giant (over 50 mm).

The most common type of cerebral aneurysm is called a saccular, or berry aneurysm, occurring in 90 percent of cerebral aneurysms. More than one aneurysm may be present at the same time in 20% of the patients with aneurysms. Two other types of cerebral aneurysms are fusiform and dissecting aneurysms.

I'm so scared! Nearly all brain aneurysms are saccular, meaning that they extend off the side of an artery. This is why these spherical protrusions can be closed off using a spring clip in surgery, or coils in an angiography suite, without occluding the normal artery. An aneurysm can be characterized by its location, shape, and cause.

The risk of a subarachnoid hemorrhage is greater with a saccular aneurysm than basis of the location of the aneurysm, its size and the condition of the person.

Differentiating a saccular aneurysm from its fusiform counterpart is imperative since repair is recommended for all saccular aneurysms regardless of size or symptomology. 1 Additionally, certain imaging features such as rapid growth, periaortic soft-tissue stranding, and periaortic fluid can suggest impending rupture. Saccular aneurysms tend to have a lack of tunica media and elastic lamina around their dilated locations (congenital), with a wall of sac made up of thickened hyalinized intima and adventitia. In addition, some parts of the brain vasculature are inherently weak—particularly areas along the circle of Willis, where small communicating vessels link the main cerebral vessels.

There were 153 (53.7%) men and 131 women with a mean age of 73.5±10.0 years. SAAs were located in the ascending aorta in two (0.6%) cases, the aortic arch in 23 (7.1%), the descending thoracic aorta in 219 (68.1%), and the abdominal aorta in 78 (24.2%).
