Vascular disorders are disorders of the vessels in your body that carry either blood or waste products. The vascular system consists of the arteries (that carry blood away from the heart), veins (that carry blood to the heart) and lymph vessels (that carry waste products to be excreted from the body). The various diseases of the vascular or circulatory system are:

Peripheral Artery Disease: Peripheral arteries carry blood to the various organs and tissues in the body. Accumulation of cholesterol and fat in the vessels narrow the pathway for the blood to flow. This can impair blood flow to the tissues in the body and cause complications. Various medications used to lower cholesterol and blood pressure can also be used for peripheral artery disease.
Buerger's Disease: This disease causes obstructions in the veins and arteries in the legs. This can hamper blood supply in the toes and the feet. It causes pain and may require amputation in severe cases. Treatments for this disease include smoking cessation and medications to dilute blood vessels.
Aneurysm: An aneurysm is swelling in the blood vessel walls; it usually occurs in the aorta. The artery walls become fragile and are placed under a lot of stress; this may lead to a sudden rupture of the aortic vessels. This disorder is usually treated by surgical procedures.
Peripheral Venous Disease: Peripheral venous disease is characterized by damage to the valves that allows blood to flow in a single direction. Damaged valves can cause blood to flow backwards and therefore, accumulate. Treatments for this disorder are incorporating certain lifestyle habits such as quitting smoking and alcohol.
Blood clots in the veins: Blood clots may occur in the veins present inside the muscles of the thighs and lower legs which lead to deep vein thrombosis. You may be prescribed anti-coagulants, also known as blood thinners, to treat this disorder.
Causes
People with diseases such diabetes, high blood pressure, or kidney failure can be more likely to have vessel problems. Working with vibrating tools, being in cold temperatures, and smoking can worsen vascular problems. Causes of vascular disorders usually fit into one of 5 groups:

Traumatic, which occur after injury
Compressive, which occur when the pipes flatten
Occlusive, which occur when pipes are blocked
Tumors (growths) or malformations (deformed, tangled pipes), which may or may not be present at birth
Vessel spasms, which occur when abnormal control of vessels causes them to narrow
Symptoms
Symptoms of vascular disorders can include:

Pain
Abnormal color changes in the fingertips
Ulcers or wounds that do not heal
Hand problems when in cold temperatures or locations
Numbness or tingling of the fingertips
Swelling
Cool or cold fingers and/or hands

5 Common Vascular Disorders

Dialysis is a very important and life-saving procedure. It is performed to replace kidney function in case of renal failure. Wastes and extra fluids in the blood are filtered out during this process. To be able to perform Dialysis, the connection between the patient s bloodstream and the equipment for performing Dialysis (dialyzer) outside the body is established. This connection is created through Dialysis Access Surgery. It is a type of Vascular Surgery which forms the vascular opening for access during Dialysis. Thus, Dialysis Access Surgery is the lifeline for the survival of the patient.

Types of Vascular Access for Dialysis- 
There are three types of Vascular Access for Dialysis: Arteriovenous (AV) Fistula, Arteriovenous (AV) Graft, and Venous Catheter.

  Arteriovenous (AV) fistula is a surgical connection of an artery to a vein. An AV fistula is usually placed in the upper arm or in the forearm. It causes extra blood to flow into vein making it grow large. A larger vein hence provides easy access to blood vessels. An AV fistula is preferred over other methods as it lasts longer than other methods of access and provides a good flow of blood. Moreover, it is less prone to infection and blood clots than other methods. Before an AV Surgery, a Vessel Mapping Test is sometimes performed for assessing the blood vessels most suitable for Dialysis. An AV fistula is performed under local anaesthesia and requires two to three months for maturation before hemodialysis. If it fails to mature, the procedure is repeated.

  Arteriovenous (AV) graft is performed when AV fistula fails to mature. It is hence the second most preferred choice for long-lasting access to vascular tissues for Dialysis. An AV graft is a looped plastic tube which establishes a connection between an artery and a vein. Like AV fistula, AV graft is also performed under local anaesthesia. It is slightly more difficult to maintain than an AV fistula.

  A venous catheter is used for short- term hemodialysis. It is a tube which is inserted into chest, neck, leg, or near groin for vascular access. After exiting the body, the tube splits into two halves. In the case where a renal disease has made quick progression leaving little or no time for the AV fistula or AV graft to mature, a venous catheter is used to establish the required vascular connection. This procedure is also performed under local anaesthesia. It is a tool for emergencies but is not suited for long- term use. It can cause narrow vein due to an infection,
scarring, or blood clot. If long- term venous catheter is used, it is tunnelled under the skin which has fewer problems associated with it and is more comfortable. 

How to Care for a Vascular Access?
  Get checked for infections and other problems before each hemodialysis session;
  Use the operated site for access only for the intended use;
  Always keep the access clean;
  Prevent cutting or bumping the access;
  Check for thrill/ vibration in the access and inform the doctor if any;
  Do not put pressure on the access site;
  Do not put blood pressure cuff around the access arm;
  Do not wear jewellery or tight-fitting garments over the site;
  Do not lift a weight.

Take Away-
Vascular Surgery for Dialysis is performed to provide vascular access for the procedure. AV fistula is the most preferred type followed by an AV graft. A venous catheter is recommended to be used only in case of an emergency when there is not much time left for the other two options to mature.

Vascular Surgery - Can It Help For Dialysis?

Coronary artery disease or CAD is the name given to the heart condition in which the major blood vessels that supply your heart with blood, oxygen and nutrients, also called coronary arteries, get blocked, damaged or diseased.

Blockages usually happen when cholesterol-containing deposits called plaque deposit in your arteries. Plaque narrows the lumen of your coronary artery which means your heart gets lesser and lesser oxygen and nutrients to function properly.
Inflammation is also to blame for coronary artery disease.
Common symptoms of CAD include

Angina or pain in the chest
Shortness of breath
If the blockage is complete, you can get a heart attack.
Common Diagnostic tests
When you go to a heart specialist, she will ask questions about your medical history and follow it up with a physical exam and order routine blood and diagnostic tests to confirm CAD like:

Electrocardiogram (ECG): An ECG records electrical signals as they travel through your heart revealing evidence of a previous heart attack or one that s happening. Holter monitoring is a type of ECG where you wear a portable monitor for 24 hours as you go about your normal daily activities. Abnormalities in the results suggest reduced blood flow to the heart signaling CAD.
Echocardiogram: This test uses sound waves to produce images of your heart. It helps your doctor determine whether all parts of your heart wall are contributing to your heart's pumping activity. If certain parts are moving weakly it can mean damage to muscle due to a heart attack or because of receiving too little oxygen- again signaling CAD.
Exercise Stress test: This test is done by making you do exercises like walking on a treadmill or riding a stationary bike during an ECG. Sometimes, medication to stimulate your heart may be used instead of exercise.
This again detects areas in your heart that receive less blood flow.

Cardiac catheterization or angiogram. A special dye is injected into your coronary arteries to observe blood flow through your heart in a test known as an angiogram.
The dye is sometimes also injected into the arteries through a long, thin, flexible tube called catheter that is threaded through an artery in your leg to the arteries in your heart. This procedure is called cardiac catheterization. This test is very good in diagnosing CAD as the dye outlines narrow spots and blockages on the X-ray images of your heart.
Heart scans. Computerized tomography or CT can help your doctor actually see calcium deposits in your arteries that can be narrowing your arteries. If a substantial amount of calcium deposits are found, coronary artery disease could be the reason.
MRI scans are also done to diagnose CAD.

Common Tests For Coronary Artery Disease!

Peripheral Artery Disease (PAD) is a disease of blood vessels that are located outside the heart and brain. The condition develops due to fatty deposits in the arteries and veins that stops the blood flow to the heart and mind as the case may be. It narrows the artery and restricts the blood flow, which causes problems to other organs of the body such as kidney, liver, and stomach.


Symptoms of Peripheral Artery Disease-
Peripheral Artery Disease is the most common type of condition in people. Some people may not even notice the symptoms. The symptoms include:

Pain in the hips and lower leg area.
Brittle toenails.
Short breath while taking stairs.
Pain in the calf.
Numbness and coldness in the leg around a calf
Hair loss on legs and feet
Erectile dysfunction in men
Repeated sores and ulcers in legs
Causes of Peripheral Artery Disease-
The most common cause of Peripheral Artery Disease is the deposit of fatty substances inside the arteries. The fatty deposits build in the arteries gradually with a process called Atherosclerosis. Most of the time people do not know that they are facing the problem of Atherosclerosis. With time deposits increase and the arteries become narrow. It restricts the blood flow and causes problems for other organs.
Another cause for Peripheral Artery Disease is clot created in the arteries due to diabetes. Also, this problem is common in diabetic patients and increases with old age.

The risk factors that contribute to the development of Peripheral Artery Disease are high blood pressure, bad cholesterol, obesity, and diabetes.

Diagnosis of Peripheral Artery Disease-
The primary way to test and diagnose Peripheral Artery Disease is to check the blood pressure in the arm and ankles. If the pressure is low as compared to arm in the ankles, one might be facing Peripheral Artery Disease. It is commonly known as the ankle-brachial index. Other ways to determine Peripheral Artery Disease are CT scans, angiography, and blood tests. Since the disease is prevalent and gradually progress, most of the time it remains undetected.

It is essential that Peripheral Artery Disease gets detected and treated well in time. If the condition persists for a more extended period of time, it may result in loss of leg, increased chances of coronary artery disease and carotid atherosclerosis.

Treatment for Peripheral Artery Disease-
The only way to treat Peripheral Artery Disease is to indulge in physical activity. A regular regime of exercise and physical work will help a person to burn fat and makes the arteries fat free. Doctors suggest that daily 30 minutes of walking or gyming will help treat Peripheral Artery Disease with significant effects. One may notice the signs in just a couple of months.

Along with exercise, one also needs to monitor the weight and eating habits. Foods that are rich in fats and bad cholesterol should be avoided. Make changes in the lifestyle and eat a healthy balanced diet. Include fruits and fresh vegetables in the diet and follow a low carb diet for regular food intake. If a person is addicted to smoking and alcohol, then he/she should consider leaving the bad habits for their own good health.

Take Away-
Above are some of the common and tried treatments. However, it is advisable to consult a doctor before opting for any of these options as these treatments are depended upon the condition of the patients.


Learning In depth About Peripheral Artery Disease!

Varicose veins are enlarged and gnarly veins and they commonly appear in the feet and legs. They occur when veins get filled with blood and they are often red or bluish purple in color.

The main cause of varicose veins is the when the vein dysfunctions. Veins have valves in them that are supposed to keep the blood flowing forward, but if they fail to do so, blood in the vein starts to collect rather than continue towards the heart. Since the legs are furthest from the heart, varicose veins mostly affect the legs. Gravity, too, is a contributing factor as it makes it hard for the blood to flow up the vein.
Out of all the treatments available for varicose veins, sclerotherapy is the most effective.

What is sclerotherapy?
Sclerotherapy is a form of injection therapy that is designed to improve the way the varicose veins appear on your legs.

The Procedure
During the procedure, a solution called sclerosant is injected in the veins that scars and destroys the vein's internal lining which causes the blood to clot. After the solution is injected, pressure over the veins is applied to prevent the return of the blood as you stand up. Compression stockings are worn for maintaining the pressure.

After the Procedure
There is no prolonged recovery time for sclerotherapy. You can move around immediately after the procedure, but do not strain yourself too much. However, bed rest is not recommended as it might stress the vein. You probably have to keep wearing the compression stockings for a few days more.

Reasons for Choosing Sclerotherapy
Sclerotherapy is best for treating the following problems-
1. Small veins and spider veins that do not cause severe damages
2. Smaller varicose veins that might return even after vein stripping surgery (the surgical removal of the superficial saphenous vein with minimal incisions to treat varicose veins).
3. Larger varicose veins
4. Follow up to any other surgery to treat varicose veins

Risks involved
Sclerotherapy, like any other treatment, has certain risks. The risks include-
1. Skin discoloration
2. The varicose veins can still return after the treatment
3. Bruising, itching, blistering and pain in the treated area
4. Mild or severe allergic reaction to the solution (sclerosant) used
5. Blood clots in the deep vein system.

Varicose Veins: Using Sclerotherapy to Get Rid of It

Peripheral Artery Disease (PAD) is caused by atherosclerosis or plaque build-up in the leg arteries. Mostly, individuals with PAD have mild or no symptoms. But with the extension of the blockages, individuals may experience disability and pain that restricts free walking. In more severe cases, individuals may develop a risk of losing their limb if the circulation is not improved. 

There are various ways to improve the flow of blood in the leg, especially for individuals with severe PAD. The objectives of improving the blood flow in the limb include improving functional ability, reducing pain, preventing amputation, and providing a better quality of life. 

Symptoms 

Symptoms of Peripheral Artery Disease may include gangrene, claudication or pain in leg muscle while walking, pain at night mainly in the feet and leg, and feet sores.

Bypass Surgery

There are a number of treating methods for PAD. Both invasive and traditional methods are used to treat Peripheral Artery Disease. 

Stenting and Angioplasty are invasive treatment methods. The traditional method includes bypass surgery. The best available treatment method for an individual depends upon various factors such as severity, location of the artery blockage in the leg, general health of the patient, history of any vascular problems, and previous treatments.

Surgical bypass in the leg or Lower Extremity Bypass Surgery is usually the last option for the patients with PAD. This method is used when all the other alternative treatment methods fail or are not suitable for the individual. During the Leg Bypass Surgery, the surgeon forms an alternative channel for blood flow to bypass or avoid the blocked area and restore the direct flow of blood to the lower leg and foot. 

The risks and benefits of the surgery are calculated prior to the surgery. For the best result of the surgery, surgeons try to use the patient s own saphenous vein, from inside the leg, to execute these grafts. Surgeons may also use veins from other leg or arms or use prosthetic or artificial graft, in case the required length of the saphenous vein cannot be achieved. 

The results of artificial and saphenous vein from other limbs are not as effective as the saphenous vein from the same leg. Thus, the availability of an appropriate vein to execute this method is an important consideration that is taken into account before the surgery. 

Takeaway

Leg Bypass Surgery is one of the medical procedures for the treatment of Peripheral Artery Disease. In PAD, the artery of the leg is blocked which can hinder the daily life of the individual. 

The symptoms can be mild or absent but, in the case, where symptoms are severe, and affecting the quality of life of the patient, treatment becomes a necessity. Bypass surgery is the last option used when other alternative methods fail to help the patient.
