A naturally occurring saccular aneurysm at the ascending aorta is an extremely rare clinical entity w2x. Usually it occurs secondarily to the trauma, infection, autoimmune disorders such as Behcet's disease or other collagen vascular diseases or due to previous cardiovascular surgery w3x.


Saccular Aneurysms. Saccular aneurysms, also called berry aneurysms, are thought to be present in at least 1% of the general population and possibly 2%. 58 These aneurysms are considered congenital and degenerative because it is currently believed that both a preexisting weakness in the tunica media and wear and tear over a long time (i.e., shear stress to arteries from turbulent blood flow, high blood pressure, cigarette smoking, and other factors) are necessary.

The white arrow points to the entrance of the saccular aneurysm, which is occupying the upper half of the aorta. Bifurcation of common iliac arteries (yellow arrow) through the true lumen can be seen. Aneurysm, sinus of valsalva, congenital; Anomaly of aorta; Congenital (at birth) pseudocoarctation of the aorta; Congenital (present at birth) hypoplasia aortic arch; Congenital aneurysm of sinus of valsalva; Congenital anomaly of aorta; Congenital dilatation of aortic arch; Congenital dilatation of aortic root; Congenital hypoplasia of aortic arch; Congenital hypoplasia of aortic arch (at 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.

Shang and colleagues4 reported that saccular aortic aneurysms comprised only 1.5% of the entire aortic aneurysms. The geometry of aortic arch is Saccular aneurysm is an outbulging of certain part of aortic circumference maintaining the continuity with the aortic lumen. False aneurysm (pseudoaneurysm) is produced by a contained rupture of the aorta followed by outbulging of the histological layers and is usually covered by a fibrous peel. A naturally occurring saccular aneurysm at the ascending aorta is an extremely rare clinical entity w2x.

The traditional definition of an aneurysm is dilation of a blood vessel wall so that the resulting caliber is 50% greater. 3 This size-based definition does not account for morphologic characteristics such as focal saccular dilation of the aorta due to trauma, penetrating atherosclerotic ulcer, and infection.

Saccular aneurysms were less frequently observed in the abdominal aorta (n = 78, 24.2%), aortic arch (n = 23, 7.1%), and ascending aorta (n = 2, 0.6%). One hundred twenty-three (43.3%) patients had one or more concomitant aneurysms, either fusiform or saccular. An aortic aneurysm is an abnormal bulge that occurs in the wall of the major blood vessel (aorta) that carries blood from your heart to your body.

Figure B shows a thoracic aortic aneurysm (which is located behind the heart). Figure C shows an abdominal aortic aneurysm located below the arteries that supply blood to the kidneys. Aortobronchial fistula (ABF) is a rare condition which can be lethal if left untreated. Open surgical treatment carries high morbidity and mortality.

Aortic aneurysms tend to slowly grow over time. If the aorta becomes too large, it may be at higher risk for rupturing (bursting) or tearing (aortic dissection), 


Symptoms of an abdominal aortic aneurysm include abdominal pain, low back pain, low blood pressure, and symptoms of shock. In the majority of cases, an abdominal aortic aneurysm develops slowly with no symptoms or only minor symptoms, such

While aneurysms may occur anywhere in the body, the most likely locations are the cerebrum, or brain , and the aorta , a large blood vessel that travels from the left ventricle of the heart, through the chest, carrying blood to the vital organs.

Aneurysms can also be a nidus (starting point) for clot formation and embolization.The word is from Greek: ἀνεύρυσμα, aneurysma, "dilation", from ἀνευρύνειν We describe an unusual presentation of a large saccular aneurysm of the ascending aorta, mimicking an acute coronary syndrome. The compression of the aneurysm on the left main coronary artery was probably the cause of these confusing symptoms. Our experience confirms the fundamental role of modern cardiac imaging techniques in the differential diagnosis of these unusual cases and in the 2013-10-01 2016-11-18 A patient with a saccular aneurysm of the thoracic aortic arch presented with severe right ventricular failure due to pulmonary artery compression.
