Possible Complications
An aneurysmal dilatation is frequently complicated by a blood clot that is lining the inner wall. This can allow small fragments to migrate further and thus cause blockage of other small arteries.
The most feared complication of an aneurysm is its rupture. This is a life-threatening emergency.
A ruptured abdominal aneurysm causes intense pain in the stomach area.
A ruptured thoracic aneurysm causes excruciating pain in the upper chest, which can also spread to the back. Blood loss and failure of vital organs such as the kidneys can be fatal in thoracic or abdominal aneurysms.
A ruptured brain aneurysm causes a hemorrhagic stroke, with all its accompanying symptoms. Excess pressure from bleeding can prevent oxygenation of the surrounding brain areas and cause their destruction, resulting in death or highly disabling after-effects.
