Angioplasty is the procedure of opening a coronary artery blockage with the help of wire balloon and stent. This procedure is done to open the blocked coronary arteries if they are causing symptoms or acute heart attacks.

HOW IT IS DONE?

The procedure is usually done in local anaesthesia. A wrist artery (radial) or a groin artery (femoral) is used to gain access to the coronary artery as is done in angiography. A hollow tube called a catheter is passed upto heart artery and through this, a guidewire is passed across the blockage and over this wire balloon is passed and blockage dilated.

After this balloon is removed and the metallic stent is passed over this wire. The stent is then inflated and it takes its shape of the hollow tube so that the flow in the coronary artery is restored.

WHAT ARE INDICATIONS OF ANGIOPLASTY AND STENTING:

An acute Heart attack is the most definite indication of angioplasty and stenting. At the time of the heart attack, there is an urgent need to restore the blood flow of block coronary artery which is usually not possible with medicines alone. Angioplasty is the most effective and definite way of opening the artery urgently in such situation.

SHOULD ALL BLOCKAGES BE OPENED UP BY ANGIOPLASTY AND STENTING?

NO, all blockages do not warrant this procedure. There is some amount of risk involved in the angioplasty procedure itself. When the risk of blockage is considered more than the risk of opening the artery then the procedure is indicated. Patients who are doing good on medicines may be followed up without angioplasty.

Varicose veins are large veins that appear on the legs of some patients. Usually, blood travels to the legs from the heart through the arteries, and the veins take it back to the heart. The valves in the veins allow the blood to travel from the legs to the heart against gravity. During this process, the valves may leak and blood may collect in the veins, making them appear enlarged.
EVLT (Endovenous laser therapy) is the latest method for curing varicose veins without surgery. It heats the affected veins them through a laser instead of removing them.
Process
In this process, at first, an ultrasound scan is carried out to locate the veins that have to be treated. After marking them, the doctor applies local anaesthetic on the skin and a needle is inserted into it. A wire is then passed through the needle up to the target vein. Over this wire, a catheter is passed after removing the needle. After that, the wire is removed.
Through the catheter, a laser fibre is placed whose tip usually reaches up to the groin crease. Using tiny needles, a large amount of local anaesthetic solution is applied in the region surrounding the vein. The laser is then applied for 5 minutes on the veins. You might hear a buzz or feel a burning sensation but won t feel any pain. The catheter and the laser are then removed and the incision is covered.
The process takes about 30 minutes to complete. After the treatment, you will be advised to wear compressions stockings and can go back to your normal routine immediately.
Benefits
The different benefits of the surgery are:
The skin does not have to be stitched 
There is no pain in the process and patients can go back to work right after the treatment
The process is free from complications 
No scars are left after the treatment

Common uses of the process
EVLT is also used for treating the following:
Swelling of the veins 
Discolouration of the skin
The heaviness of the leg
Skin ulcers and irritation
Precautions
These are the precautions that you must take:
A week before the process, avoid taking arthritis medications, aspirin, and Ibuprofen as they can increase the chances of bruising 
Avoid alcohol and tobacco 2 days before the procedure
After the treatment, ask someone to drive you back home and do not use public transport
Avoid activities like swimming, running, jogging and weightlifting for at least 2 weeks after the procedure

The varicosities fade away after the process but rarely disappear completely. You might require further treatment for improving the appearance of the veins.

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.

It is said that if all the veins of the human body were laid out in a single line, it would stretch over 60000 miles. We don t usually think of our veins or notice them unless an intravenous injection is to be administered or the person suffers from varicose veins. These veins are usually benign and can be described as enlarged veins that rise to the surface, and become prominently visible. The varicose veins can usually be seen on the feet and calves. For most people, it is simply a cosmetic problem but for others it can be the cause of pain and discomfort. The good news is that in either case, varicose veins can be treated.

EVLT refers to Endovenous Laser Therapy, which is also known as EVLA or Endovenous Laser Ablation. This is a type of laser therapy that can be used to destroy veins from within. The procedure is performed while the patient is under local anesthesia and hospitalization is not required. Know the steps in which it is carried out:

The first stage involves mapping the veins and identifying the problem veins. A Duplex Ultrasound is usually used to create this map. It is important to note that this procedure cannot treat bulging veins on the surface of the skin. The veins that can be treated include the Great Saphenous Vein (GSV), Small Saphenous Vein (SSV) and their major tributaries.
Once the veins have been identified a needle is inserted into the vein near the ankle or knee with the help of ultrasound controls. A wire is then passed into the vein and a long sheath is then passed to the top, and positioned with the help of the ultrasound.
Ultrasound is again used to then inject local anesthetic into the area around the vein. This numbs the vein and surrounding tissue. The adrenaline in it also makes the vein contract, so as to fit the sheath perfectly. This technique is called  Tumescent anesthesia .
This is followed by passing a laser fiber inside the sheath and switching the laser on. The laser and sheath are then pulled back simultaneously so as to destroy the vein without damaging any of the surrounding tissues.
Once done, you should be able to get back to work and your normal lifestyle, the day after the surgery. But it is advisable to take good rest for few days, before you get back to your regular routine. Your doctor may advise you to wear compression stockings for up to 2 weeks. You should also avoid letting your legs come in contact with water. To avoid getting varicose veins in future, exercise regularly and have a balanced diet to control your weight.

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

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.
