Blood flows through the tubes called as blood vessels. There are two networks of blood vessels   the arteries and the veins. The arteries carry pure or oxygenated blood from the heart to the various parts of the body. The veins, on the other hand, collect impure blood from all over the body and reach it to the heart. Blood flow in the veins is controlled via valves, which ensure blood does not flow in the reverse direction (against its desired direction of flow). The veins in the legs, which are farther from the heart, are quite thick and exert extra pressure to pump blood into the heart. They need to transport blood against gravity and so in people who are prone to stand for long hours, they can become thicker, swollen, twisted, and engorged. In severe cases, there could even lead to bleeding.

Some common causes for varicose veins are:

Damaged valves which are not able to control the flow of blood in the required direction.
Veins with a thin wall that are unable to control blood flow.
Risk factors: Though these are the suspected causes, there are specific risk factors which aggravate the condition of varicose veins.

Family history
Smoking
Occupations which require prolonged standing (construction jobs, painters, etc.)
Pregnancy
Obesity
Age, which reduces the elasticity of the veins
Surgery in the leg, which could have hampered the values or veins
There are quite a few symptoms of varicose veins. These are quite distinct and present as:

Swollen, ropy leg veins which can be blue
Pain, especially with prolonged standing
Tenderness on touching the veins
Itching and heaviness along the veins
Skin changes like scaling and dryness
Night cramps around the area
Susceptibility to bleed from these veins
While varicose veins are easy to diagnose given their distinct clinical presentation, some additional testing can involve the following:

Doppler ultrasound
Scanning
MRI
As said, prevention is better than cure; here are some preventive measures that can be really helpful:

Elevate legs as much as possible. When working, take short breaks to reduce stagnation and promote blood circulation
Quit smoking
Avoiding alcohol, as it causes venous dilation
Weight management
Avoid tight clothing and sitting with cross-legs for prolonged periods as they put a lot of pressure on the veins and valves
Follow a regular exercise regimen to improve blood flow in the legs, like walking or running
Starting from the least invasive to the most, this condition can be treated by:

Compression stocking (Ted hose or Jobst stocking) which improves circulation and reducing pain
Surgical options include sclerotherapy, laser treatment, and stripping off the vein. These are done in very severe cases, but quite rare.

Varicose Veins - How Best It Can Diagnosed?

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?

Formation of blood clots in the arteries of the lungs, heart or legs can actually kill a person. In such a case, the immediate medical action is necessary and the only way to deal with blood clots is thrombolysis.
Thrombolysis or thrombolytic therapy is a medical process that dissolves blood clots and facilitates blood flow to all parts of the body. Thus, it protects tissues and muscles from damage.

What are the causes of blood clots in the body?

  Poor blood circulation
  Conditions such as Deep Venous Thrombosis and atrial fibrillation
  Blood clots can also be formed because of dialysis catheters and by-pass grafts

How can you tell if you have blood clots?

  Swelling in one or more legs
  Cramp and tenderness in the legs
  Breathing trouble might indicate that blood clots have travelled to the lungs
  Sweating and frequent chest pain may suggest that blood clots have travelled to the heart

How is Thrombolysis performed?

Thrombolytic drugs are injected into the body intravenously. They make their way to where the blood clots exist and dissolve them. If there is a medical emergency, the drugs are delivered to the exact location of the blood clots and immediately start dissolving them. Another method is inserting a device into the blood clot infested region to break the clots up. The drugs which on entering the body dissolve blood clots are called thrombolytics. There are many varieties of thrombolytics such as the following-

  Streptokinase - It is a kind of enzyme. It is used when a person has just suffered a heart attack or pulmonary embolism. Doctors do not usually prescribe the second usage of this drug. It is injected into a vein and can be administered to pregnant women.

  Tenecteplase - Also an enzyme, it is a plasminogen activator. When it binds to the surface of the blood clot, it makes the clot degenerate.

  Reteplase - It is actually extracted from E-Coli. It is a sterile intravenous bolus injection

The leading cause of heart attacks and ischemic heart disorder is the formation of blood clots in the arteries that connect the heart and the brain. Thrombolysis is often employed as an emergency treatment for this purpose. Thrombolysis is also effective against blood clots formed in the lungs (which lead to acute pulmonary embolism). Sometimes blood clots are formed in the legs, upper extremities of the body, the pelvic region (deep vein thrombosis). These clots may travel to the lungs and heart.

Consult your doctor before undergoing the treatment.

Thrombolysis - Causes, Symptoms & Treatment Of It!

In our bodies, the vascular system is composed of vessels. This system is comprised of a complex network of veins and arteries. The arteries transport oxygenated blood away from the heart and spread it throughout our bodies and veins brings the deoxygenated blood (oxygen-poor) back to the heart for purification. Whenever this complicated process gets disturbed, pain, dysfunction of the system, and other complications may occur.

Most common complications among all are:
1. Abdominal Aortic Aneurysm: This condition is when there is a  bulge  formed in the weak area of the largest artery in the abdomen and keeps on increasing with each pressure flow of blood from that artery. This condition weakens the artery further and massive internal bleeding may occur.

2. Carotid Artery Disease - Stroke: This condition arises when the main blood vessels flowing blood to the brain develops a plague caused due to hardening of the arteries (atherosclerosis). The continuous increase of plague can cause a stroke.

3. Peripheral Arterial Disease: This condition occurs when the flow of oxygen-rich blood is insufficient to the lower limbs of the body due to hardening of the arteries in that area. This can cause difficulty in walking, foot ulcers, infections and can even lead to amputation.

The complication of these types are corrected by the vascular surgeon with the process is commonly known as vascular surgery. However, this condition is sometimes medically managed by an innovative, less invasive procedure called Endovascular surgery. 

Vascular Surgery-
Vascular surgery is generally the traditional surgery that corrects the diseases outside of the heart and the brain. This procedure is more invasive as it involves incisions that are surgical in nature. Vascular surgery comprises of the surgery of the aorta, carotid arteries, and other small diametric arteries. This surgery also involves surgery of veins for treating various conditions such as varicose veins and May-Thurner syndrome.

Endovascular Surgery:
However, this type of surgery is an innovative way to treat medical conditions related to the vascular system. For instance, during the procedure of treating the Abdominal Aortic Aneurysm, it involves making a small cut near the hip area and inserting the endovascular graft through the arteries and is positioned inside the aorta, in a catheter, which is a flexible, long, and narrow tube. The endovascular graft is a tube device made up of special fiber and is framed within stainless steel self-expanding stents. The grafts expand and seal off the aneurysm. This stops the internal bleeding the system and the graft remain in the aorta permanently.

This method has a short recovery time, smaller incisions, less discomfort, less stress on the heart and has fewer risks. This surgery is appropriate for the patient who is at high
risk of complications. 

Take Away-
Diseases related to artery and veins are now being treated with various methods such as angiography, stenting, sclerotherapy in various countries. These days vascular surgeons have become proficient with the endovascular surgical methods. Endovascular surgery is durable and less painful and stressful when viewed with the context of vascular surgery. However, the cost of staying longer at the hospitals is somewhat got balanced by the high cost of imaging equipment and other high financial expenses in the endovascular surgery.

Endovascular VS Vascular Surgery - Know The Difference!

Coronary artery disease is characterized by accumulation of plaque in the coronary artery that chokes blood supply to the heart. This plaque buildup usually starts with cholesterol accumulation and gradually other particles such as calcium and lipoproteins get deposited as well. Over time, the plaque accumulates, making the blood vessels narrow and choking the supply of blood. In some cases, if the plaque ruptures, it may lead to formation of blood clots resulting in stroke.

The symptoms of coronary artery disease are:

1. Breathing difficulties: This disorder may lead to shortness of breath as the blood pumping mechanism of the heart is impaired; this usually results in fatigue and exertion. It is advised to avoid advanced cardio exercises such as the high intensity interval training.

2. Chest pain: Stress related activities may cause intense pressure or tightness in your chest, resulting in pain in the middle or left portion of your chest. If you discontinue the activity, the pain would usually subside. In some cases, you may feel the pain in the arm and the neck.

3. Heart attack: If the level of plaque accumulation is excessive, then it may result in a heart attack. It is characterized by breathing difficulties, pain, tightness in the chest and sweating. You may also experience pain in the neck and the jaw.

The causes of coronary artery disease are:
1. Smoking and alcohol consumption
2. Leading a sedentary lifestyle ups the risk of coronary artery disease
3. Hypertension
4. High cholesterol levels in the body
5. Blood sugar problems

Treatment
1. Get your blood pressure under control: If you suffer from high blood pressure, then it is recommended to get it under control to prevent coronary artery disease.
2. Quit smoking: If you are a habitual smoker, then it is time to nip the habit in the bud. Smoking is known to constrict blood vessels as it is a vasoconstrictor.
3. Eat healthy: Eat a well balanced diet consisting of vegetables and fruits so that your body receives the essential nutrients to function well.
4. Beat stress: You need to control your stress levels through exercise or meditation. Take time off work and do activities that make you happy.

Coronary Artery Disease: Causes and Treatment

Varicose veins are superficial, swollen, enlarged and twisting veins, often appearing dark purple or blue on the feet and legs. The condition occurs when blood through the veins flow in the wrong direction and starts accumulating.

Although varicose veins is not a serious condition, you should seek treatment if it causes symptoms like swelling and pain in the extremities. In severe cases, where a varicose vein ruptures or develops to form skin ulcers, your doctor may recommend laser treatment.

Can laser treatment cure varicose veins?

Laser surgery can effectively treat varicose veins. The procedure involves using a high-intensity beam of light to reduce enlarged, bulging veins that are observed usually on the calves or thighs.

How does the procedure work?

The heat emitted from the laser damages a vein, which causes scar tissues to form. This scar tissue shrinks and closes the vein. A closed vein gradually loses its source of blood and dies. After some time, usually in a year or two, the vein disappears on its own.

Two types of laser surgery are performed, namely  

  Simple Laser Treatment   This is done on the outer layers of your skin. It can cure small varicose veins and spider veins under the skin surface. Normally, more than one session, scheduled every 6-12 weeks is needed.
  Endovenous Laser Treatment   This particular procedure is used to cure large varicose veins that appear on the legs.
The steps of the procedure are as follows  
  Your healthcare provider will administer local anaesthesia to numb the area. You may be provided with an eyeglass to protect your eyes
  The surgeon will make a small incision on the skin and pass a laser fibre through a catheter into the veins while closely monitoring the vein on a screen
  As he/she pulls out the catheter, the length of the vein will heat up and shrink, and eventually close

This outpatient procedure is less painful than stripping and litigation. It has a shorter recovery period and can be performed under local anaesthesia or mild sedatives.

What to Expect

After the laser treatment, you can walk around without much complication. The recovery period is typically brief. You can expect to return to your daily activities following simple laser surgery. However, you might need to wear a compression stocking for a week or so after the endovenous laser procedure.
You may notice redness, bruising or burns on the skin after the treatment. That is only normal, so you need not worry. Do follow up with your doctor to see if the vein has closed.
