Why is Vascular Surgery Performed?
The vascular system is the network of veins that move throughout the body. Vascular surgery is performed to treat the following conditions:
Carotid Artery Disease
Carotid arteries are the arteries that carry the blood to the head and neck. When plaque builds up inside the carotid arteries, it may cause a stroke. To prevent stroke, vascular surgery is performed to treat the affected carotid artery.
It is the dilation of blood vessel(s) which can lead to a rupture and ultimately result in death. Aneurysms can occur in any part of the body, but they are most common in brain, legs, spleen and aorta. It occurs when the wall of an artery weakens, causing an abnormally large bulge.
Critical Limb Ischemia
This condition occurs when there a severe blockage in the arteries, leading to a reduction in the blood flow. If this condition is not treated timely, the surgeon might have to amputate the limb.
Chronic Venous Insufficiency
When the leg veins do not allow blood to travel back to the heart, the person is said to be suffering from a chronic venous insufficiency. A problem with the valves in the veins can cause the blood to flow in both the directions - to and from the heart. Varicose surgery is a must to treat the condition.
Lymphoedema is the swelling caused by the accumulation of fluid in the body’s tissue caused by blockage of lymphatic vessels.
Peripheral Vascular Disease (PVD)
PVD is a progressive yet slow circulation disorder caused by blockage, narrowing or spasms in a blood vessel. Vascular surgery is a bypass graft in which the blocked artery is replaced by a blood vessel from another part of the body or a synthetic tube. The new blood vessel or synthetic tube is used to reroute the blood flow.
Pulmonary Embolism or PE is a blood clot that develops in a blood vessel of a leg. The clot then travels to the lung artery where it can suddenly block the flow. An embolus is the blood clot that forms in one area, breaks off and then travels to a different area of the body.
Renal Vascular Disease
This disease affects the blood flow in and out of the kidneys which may cause high blood pressure, kidney damage and kidney failure.
