Retinal Vessel Occlusion The retina is the light-sensitive layer at the back of the eye that is responsible for vision. Blood circulation to most of the retina's surface is primarily through one artery and one vein. If either blood vessel or one of their smaller branches is blocked, blood circulation to the retina can be significantly disrupted. The blockage is called an occlusion.

Peripheral Arterial Disease (PAD) Your doctor may recommend bypass grafting surgery if blood flow in your limb is blocked or nearly blocked. For this surgery, your doctor uses a blood vessel from another part of your body or a synthetic tube to make a graft. This graft bypasses (that is, goes around) the blocked part of the artery. The bypass allows blood to flow around the blockage. This surgery doesn’t cure P.A.D., but it may increase blood flow to the affected limb.

Overview Arteriovenous fistula. An arteriovenous (AV) fistula is an abnormal connection between an artery and a vein. Normally, blood flows from your arteries to your capillaries to your veins. Nutrients and oxygen in your blood travel from your capillaries to tissues in your body.With an arteriovenous fistula, blood flows directly from an artery into a vein, bypassing some capillaries.When this happens, tissues below the bypassed capillaries receive a diminished blood supply. Arteriovenous fistulas usually occur in the legs, but can develop anywhere in the body.ith an arteriovenous fistula, blood flows directly from an artery into a vein, bypassing some capillaries. When this happens, tissues below the bypassed capillaries receive a diminished blood supply.

Causes of Atherosclerosis Disease and Blocked Arteries The coronary arteries (that is, arteries that supply the heart) can become blocked in various ways: by plaques forming around the walls, plaque can rupture and release fatty deposits that can block the arteries, or a blood clot can attach to the plaque.

- As the blood pools, there’s a risk that the blood can form into a clot. Even a small clot can break off and travel to the brain, and once there, can lodge in an artery. This blocks blood flow to the brain, leading to a stroke or mini-stroke. Clots can also travel to other parts of the body and block blood flow.

- Common symptoms include: 1  chest pain (angina). 2  pain in the leg, arm, and anywhere else that an artery is blocked. 3  shortness of breath. 4  fatigue. 5  confusion (if the blockage affects circulation to the brain). 6  muscle weakness in the legs from lack of circulation.

Retinal vessel occlusion A retinal vessel occlusion is a blockage in the blood vessels of your eye that can cause sight loss. There are two types of retinal blood vessels, arteries and veins, and either of these can be affected by an occlusion.therosclerosis is a problem with the condition of the inside of the blood vessel's wall. Blood vessels are like tubes with the blood flowing smoothly through them. Atherosclerosis is a problem with the inside of the tube. The tube is usually wide and smooth so that the blood flows directly through it.

Lupus, Vasculitis and Blocked Blood Vessels If the blood vessels are close to the skin, characteristic rashes occur. Depending on where the blockage occurs, almost any organ in the body can be affected. (Note: Vasculopathy can also block blood vessels, but it does not cause the fever, pain, and local tenderness associated with vasculitis.

- Retinal vein occlusion occurs when one of the tiny retinal veins becomes blocked by a blood clot. This means that blood cannot drain away from the retina as easily and there is a backlog of blood in the blood vessels of the retina. This can lead to a build-up of pressure in the blood vessels.

Carotid Endarterectomy and Stenosis The body tries to restore blood and oxygen to the cells by enlarging other blood vessels (arteries) near the area. If the blockage is in a large blood vessel, such as the carotid artery, the body may not be able to supply blood to the affected area through other blood vessels.

- Damaged and hardened arteries can lead to: 1  Damaged organs. 2  Damaged arteries cannot deliver adequate blood flow to the body's organs. 3  Blood clots. 4  When arteries are narrowed by fatty deposits, you have a greater risk for developing blood clots. Heart failure is the term used for a heart that is not supplying sufficient blood flow to the rest of the body. 2  High blood pressure damages the entire complex circulatory system. 3  As mentioned above, HBP creates conditions for blocked arteries. 4  HBP adds to the workload of the heart.

What is coronary artery disease? Other causes that limit blood flow. Other rare causes of damage or blockage to the coronary artery also limit blood flow to the heart. Sometimes, plaques burst open and release blood cells called “platelets” into the artery. This then cause blood clots and further buildup.

Treatment Options for Blocked Veins Treatment Options for Blocked Veins. Deep Vein Thrombosis (DVT) can cause leg pressure, swelling.

Venous Blood Clots (Thrombi, DVT) Blood clots become dangerous when they block blood flow through an artery or a vein. When a blood clot stops blood flow to an artery in the heart or brain, a heart attack or stroke can result.

Treatment Options for Blocked Veins The location of the blood clot in the body determines how we treat the problem. Blockage below the knee. When the clot or blockage is limited to the blood vessels below the knee (the tibial veins), your body repairs itself in 90 percent of all cases. The blood vessel finds a way around the blockage and restores proper blood flow. This restoration process takes between three and six months.

Coronary Artery Chronic Total Occlusion Without adequate blood flow, the heart is starved of the oxygen and vital nutrients it needs to function properly. The most common symptom of coronary artery disease is angina or chest pain. When one or more of the coronary arteries is completely blocked, a heart attack may occur, which damages the heart muscle. If the blockage occurs more slowly, the heart muscle may create small blood vessels that allow the other coronary arteries to reroute the blood flow. In this case, angina may occur. Top of Page.

- A serious blockage can eventually occur. This reduces blood flow through the coronary artery. Atherosclerosis can also cause a blood clot to form. A blood clot can completely block the coronary artery (heart attack). Heart bypass surgery is a common but major surgery with significant risks and potential complications.

Ischemic Stroke Ischemic Stroke. Ischemic strokes occur when blood supply is cut off to part of the brain. This type of stroke accounts for the majority of all strokes. The blocked blood flow in an ischemic stroke may be caused by a blood clot or by atherosclerosis, a disease which causes narrowing of the arteries over time. Ischemic strokes can be caused by a blockage anywhere along the arteries feeding the brain.

- Deep Vein Thrombosis (DVT), Pulmonary Embolism (PE), Heart Attack and Stroke. Excessive clotting or thrombophilia can lead to the presence of a blood clot in a vein or artery that can potentially block the flow of blood and cause serious, life-threatening complications. Blood clots are referred to as thrombi (singular, thrombus) when they form in a blood vessel.

What happens when the coronary arteries are blocked? What can you do? If a coronary artery is blocked, presumably as evidenced by angiogram or other study, the area of heart tissue downstream from the blockage will be inadequately supplied with blood, potentially causing the heart tissue to die (a myocardial infarction) and if not addressed promptly may result in patient death (death).
