PERIPHERAL VASCULAR SURGERY
Vascular surgery is the treatment of surgery on diagnosed patients with diseases of the arterial, venous, and lymphatic systems (excluding the intracranial and coronary arterie
Vascular surgery is indicated when a patient has vascular disease that cannot be treated by less invasive, nonsurgical treatments. The purpose of vascular surgery is to treat vascular diseases, which are diseases of the arteries and veins. Arterial disease is a condition in which blood clots, arteriosclerosis, and other vascular conditions occur in the arteries. Venous disease involves problems that occur in the veins. Some vascular conditions occur only in arteries, others occur only in the veins, and some affect both veins and arteries.
Peripheral vascular bypass surgery is performed to restore blood flow (revascularization) in the veins and arteries of people who have peripheral arterial disease (PAD), a form of peripheral vascular disease (PVD). People with PAD develop widespread hardening and narrowing of the arteries (atherosclerosis) from the gradual build-up of plaque. In advanced PAD, plaque accumulations (atheromas) obstruct arteries in the lower abdomen, groin, and legs, blocking the flow of blood, oxygen, and nutrients to the lower extremities (legs and feet). Rerouting blood flow around the blockage is one way to restore circulation. It relieves symptoms in the legs and feet, and helps avoid serious consequences such as heart attack, stroke, limb amputation , or death.
Peripheral Vascular Disease Causes
The most common cause of peripheral vascular disease is peripheral artery disease.
- Peripheral artery disease is due to atherosclerosis. This is a gradual process in which a fatty material builds up inside the arteries.
- The fatty material mixes with calcium, scar tissues, and other substances and hardens slightly, forming plaques of arteriosclerosis.
- These plaques block, narrow, or weaken the vessel walls.
- Blood flow through the arteries can be restricted or blocked totally.
Peripheral Vascular Disease Symptoms Surgery in india
Only about half of the individuals with peripheral vascular disease have symptoms. Almost always, symptoms are caused by the leg muscles not getting enough blood. Whether you have symptoms depends partly on which artery is affected and to what extent blood flow is restricted.
A variety of complications are seen in the field of peripheral vascular surgery and range from stroke and cranial nerve injury related to carotid endarterectomy, massive bleeding and infection association with aneurysm resection to early occlusion of bypass grafts in peripheral vascular reconstruction. Additionally there are rare incidences of paraplegia associated with abdominal aortic resection and renal failure. Sexual impotence is seen with various forms of aortic surgery particularly in middle aged men who are heavy smokers. This can be associated with dissection of tissues around the aortic bifurcation but may also occur as a result of vascular occlusion to the genitals.
