An aneurysm is a localized enlargement of arteries, characterized by a balloon-like bulge. [6] It results from the abnormal weakening of blood vessel wall. [7] Common types of aneurysm include abdominal aortic aneurysm, thoracic aortic aneurysm and intracranial aneurysm. [7]
Aneurysms form for a variety of interacting reasons. Multiple factors, including factors affecting a blood vessel wall and the blood through the vessel, contribute. The pressure of blood within the expanding aneurysm may also injure the blood vessels supplying the artery itself, further weakening the vessel wall. Without treatment, these ...
The increase in pulse pressure may result in increased damage to blood vessels in target organs such as the brain or kidneys. [23] [24] This effect may be exaggerated if the increase in arterial stiffness results in reduced wave reflection and more propagation of the pulsatile pressure into the microcirculation. [23]
The most common treatments are medications and surgery to repair the damaged blood vessels in your brain. Valvular heart disease Heart valve problems may be treated with medications or surgery.
Aneurysm means an outpouching of a blood vessel wall that is filled with blood. Aneurysms occur at a point of weakness in the vessel wall. This can be because of acquired disease or hereditary factors. The repeated trauma of blood flow against the vessel wall presses against the point of weakness and causes the aneurysm to enlarge. [20]
However, several new studies in mice have shown that the nutrient manganese may reduce lipids in the bloodstream that can lead to plaque and help remove plaque from the walls of blood vessels, per ...
Atherosclerosis is characterized by the build-up of plaque inside your blood vessels. It can lead to stenosis, which is a narrowing of your artery walls. Plaque is a fatty substance made up of:
In microangiopathy, the walls of the smaller blood vessels become so thick and weak that they bleed, leak protein, and slow the flow of blood through the body. The decrease of blood flow through stenosis or clot formation impairs the flow of oxygen to cells and biological tissues (called ischemia ) and leads to cellular death ( necrosis and ...
