An aortic aneurysm is the dilation of the aorta to more than 1.5 times its normal size. It causes no symptoms except when it ruptures. Sometimes, it may result in leg, back or abdominal pain. Aortic rupture results in massive internal bleeding, which unless treated immediately, is fatal. Aortic aneurysms are of three types, classified on the basis of their location on the aorta - aortic root aneurysm, thoracic aortic aneurysm and abdominal aortic aneurysm. Aneurysms can be detected through physical examination. Medical imaging is required for confirming the diagnosis and determining the anatomic extent of the aneurysm. It can occur as a result of trauma or infection or an abnormality in the collagen and elastin components of the aortic wall. Open or endovascular surgery is the recommended treatment for an aortic aneurysm. For smaller aneurysms, blood pressure control, use of beta blockers and statins may be recommended. This book provides significant information on aortic aneurysms to help develop a good understanding of the pathogenesis and treatment of this medical condition. Those with an interest in cardiology would find this book helpful.
