aneurysm - Types, Locations, Risks, Treatment of aneurysms

vessel blood layers wall

The abnormal enlargement of a segment of a blood vessel (usually an artery) due to the weakening or rupture of some of the layers of the wall of the vessel. If the inner layer (intima) ruptures, blood passes between the layers of the vessel wall and may escape into surrounding tissues. Rupture of an aneurysm of the aorta or pulmonary trunk often proves fatal.
