| aneurysm | <anatomy, surgery> A sac formed by the dilatation of the wall of an artery, a vein or the heart. The physical signs of arterial aneurysm are the formation of a pulsating tumour and often a bruit (aneurysmal bruit) heard over the swelling. Sometimes there are symptoms from pressure on contiguous parts. Origin: Gr. Aneurysma = a widening (18 Nov 1997) |
| aneurysm by anastomosis | A mass of dilated anastomosing vessels that produce a pulsating tumour usually in a superficial position. (05 Mar 2000) |
| aneurysm, dissecting | Splitting or dissection of an arterial wall by blood entering through an intimal tear or by interstitial haemorrhage. It is most common in the aorta. (12 Dec 1998) |
| aneurysm, false | An aneurysm in which the entire wall is injured and the blood is contained by the surrounding tissues, with eventual formation of a sac communicating with the artery or heart. (12 Dec 1998) |
| aneurysm, infected | Aneurysm due to growth of microorganisms in the arterial wall, or infection arising within preexisting arteriosclerotic aneurysms. (12 Dec 1998) |
| aneurysm of sinus of Valsalva | A congenital thin-walled tubular out pouching usually in the right or non-coronary sinus with an entirely intracardiac course that may rupture into the right or rarely the left heart chambers to form an aortocardiac fistula. (05 Mar 2000) |
| aortic aneurysm | Dangeous ballooning of the aorta (the main artery leaving the heart) which is caused by disease in the artery's wall. (09 Oct 1997) |

| aortic aneurysm, thoracic | An aneurysm in the proximal portion of the descending aorta proceeding from the arch of the aorta and giving rise to the bronchial, oesophageal, pericardiac, and mediastinal branches. (12 Dec 1998) |
| aortic sinus aneurysm | Abnormal dilation of one or more of the three aortic sinuses situated behind the three aortic valve cusps. (05 Mar 2000) |
| arteriosclerotic aneurysm | The most common type of aneurysm, occurring in the abdominal aorta and other large arteries, primarily in the elderly. Synonym: atherosclerotic aneurysm. (05 Mar 2000) |
| arteriovenous aneurysm | <anatomy> A dilated arteriovenous shunt where there is communication between an artery and a vein, sometimes congenital. (05 Mar 2000) |
| atherosclerotic aneurysm | The most common type of aneurysm, occurring in the abdominal aorta and other large arteries, primarily in the elderly. Synonym: atherosclerotic aneurysm. (05 Mar 2000) |
