PATHOLOGY

Detailed explanation-1: -An aneurysm is an abnormal swelling or bulge in the wall of a blood vessel, such as an artery. It begins as a weak spot in the blood vessel wall, which balloons out of shape over time by the force of the pumping blood.

Detailed explanation-2: -An aneurysm is an abnormal bulge or ballooning in the wall of a blood vessel. An aneurysm can burst. This is called a rupture. A ruptured aneurysm causes bleeding inside the body and often leads to death. Some aneurysms may not cause symptoms.

Detailed explanation-3: -What is an aneurysm? An aneurysm is a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning greater than 50% of the vessel’s normal diameter (width). An aneurysm may occur in any blood vessel, but is most often seen in an artery rather than a vein.

Detailed explanation-4: -Aneurysms are the result of weakening and thinning of the artery wall. When a portion of the arterial wall stretches and swells to more than 50 percent of the original diameter, this is called an aneurysm.
