What is Deep Vein Thrombosis?

Blood clots can arise anywhere in your body. They develop when blood thickens and clumps together. When a clot forms in a vein deep in the body, it's called Deep Vein Thrombosis (DVT). Deep vein blood clots typically occur in the lower leg or thigh. But if your symptoms stem from a blood clot deep in your leg, it can be dangerous. Blood clots can happen to anyone, anytime. But some people are at increased risk. Therefore, they should immediately consult with vein specialist to avoid blood clot forming in the veins which can help avoid potentially serious problems.

DVT Symptoms:

"Deep vein thrombosis has classic symptoms - for example, swelling, pain, warmth, and redness on the leg," says Dr. Rajendra Bansal, a DVT treatment expert in Jaipur.  But about 30 40% of cases go unnoticed since they don't have typical symptoms.  In fact, some people don't realize they have a deep vein clot until it causes a more serious condition.

Deep Vein Clots:

DVT symptoms include deep vein clots - especially those in the thigh - can break off and travel through the bloodstream. If a clot lodges in an artery in the lungs, it can block blood flow and lead to a sometimes-deadly condition called pulmonary embolism. This disorder can damage the lungs and reduce blood oxygen levels, which can harm other organs as well.

Some people are more at risk for deep vein thrombosis than others. "Usually people who develop deep vein thrombosis have some level of thrombophilia, which means their blood clots more rapidly or easily," Dr. Bansal says, a DVT specialist in Jaipur. Getting a blood clot is usually the first sign of this condition because it s hard to notice otherwise. In these cases, lifestyle can contribute to a blood clot forming if you don t move enough, for example. Your risk is higher if you ve recently had surgery or broken a bone if you re ill and in bed for a long time, or if you're traveling for a long time (such as during long car or airplane rides).

Other Symptoms:

Having other diseases or conditions can also raise your chances of a blood clot. These include a stroke, paralysis (an inability to move), chronic heart disease, high blood pressure, surgical procedure, or having been recently treated for cancer. Women who take hormone therapy pills or birth control pills are pregnant, or within the first 6 weeks after giving birth are also at higher risk. So are those who smoke or who are older than 60. But deep vein thrombosis can happen at any age.

Chronic vs Acute DVT:

Chronic DVT refers to long-standing venous thrombosis present for more than 28 days.  It can either permanently block the vein or it can adhere to the wall of the vein.  Chronic DVT that doesn t block the vein can still cause long-term problems known as Post Thrombotic syndrome which occurs due to pooling of blood in legs by gravity as the protective valves are damaged or destroyed. Patient symptoms are:

Leg swelling after standing for long periods
Aching pain
Varicose veins
Skin ulcers in severe cases.
Acute DVT refers to venous thrombosis for which symptoms have been present for 14 days or less. The symptoms of acute DVT are sudden limb swelling and pain. During this period the clot is soft and easily treated with clot-dissolving drugs. The period between 14-28 days is called Sub-acute DVT.

Clues of a Clot:

Seek DVT treatment if you have these symptoms. They may signal a deep vein clot or pulmonary embolism:

Swelling of the leg or along a vein in the leg
Pain or tenderness in the leg, which you may feel only when standing or walking
Increase in warmth in the area of the leg that s swollen or painful
Red or discolored skin on the leg
Unexplained shortness of breath
Pain with deep breathing
Coughing up blood
A prompt diagnosis and a proper DVT treatment can help prevent the complications of blood clots. See your doctor immediately if you have any signs or symptoms of deep vein thrombosis or pulmonary embolism. A physical exam and other tests can help doctors determine whether you ve got a blood clot.

Your doctor will diagnose deep vein thrombosis (DVT) based on your medical history, a physical exam, and the color Doppler ultrasound or sometime may require CT or MRI. He or she will identify your risk factors and rule out other causes of your symptoms. After analyzing the risk factors, the doctor will tell you whether you need an immediate DVT treatment or not.

DVT Treatment

There are many ways in Deep Vein Thrombosis treatment. DVT treatment process includes medicines, certain devices, and therapies. The main goals of DVT treatment include:

Stopping the blood clot from getting bigger
To dissolve the already formed clot
Preventing the blood clot from breaking off and moving to your lungs
Reducing your chance of having another blood clot
To prevent long-term complication known as Post Thrombotic Syndrome.
Anticoagulants (Blood Thinners):

These are the most common medicines in DVT treatment. These medicines decrease your blood s ability to clot. They also stop existing blood clots from getting bigger. However, blood thinners can t break up blood clots that have already formed. (The body dissolves most blood clots with time.)

Blood thinners are taken either as a pill, an injection under the skin, or through a needle or tube inserts into a vein (called intravenous or IV injection). There are different types of  Blood thinner. The choice of anticoagulant depends upon multiple factors, including the preference of the patient and the healthcare provider, the patient s medical history and other conditions, and cost considerations.

Initial anticoagulation is continued for 5 to 10 days. After that, long-term anticoagulation is continued for 3 to 12 months depending upon the patient profile, length of vessel involvement and risk of recurrence. In some patient where permanent risk factor like a congenital cause or cancer lifelong anticoagulation may require.

Other available treatments, which are for specific situations, include thrombolytic therapy or placing a filter in a major blood vessel (the inferior vena cava).

Thrombolysis (Clot-Busting DVT Treatment):

Minimally invasive procedures in DVT treatment are performed by an interventional radiologist under X-ray Guidance, if a patient has severe pain, difficulty in walking, significant swelling while on blood thinners, or if there is clot blocking the pelvic veins (iliac veins).  When performed early, thrombolysis is highly effective at dissolving a clot and preserving the valves in the veins.

It is designed to rapidly break up the clot, restore blood flow within the vein, and potentially preserve valve function to minimize the risk of post-thrombotic syndrome. The interventional radiologist inserts a tiny tube called catheter into the vein behind the knee or other leg vein and threads it into the vein containing the clot using x-ray guidance. The catheter tip is placed into the clot and a  clot-busting  drug is infused directly to the thrombus (clot) followed by clot removal by special devices. The fresher the clot, the faster it dissolves   one to two days. Clinical resolution of pain and swelling and restoration of blood flow in the vein is greater than 85 percent with these invasive techniques.  In patients in whom thrombolysis or blood thinners are not medically appropriate, an interventional radiologist can insert a vena cava filter, a small device that functions as an umbrella to capture blood clots that would float to the lung, but allows normal liquid blood to pass.

DEEP VEIN THROMBOSIS PREVENTION:

You can take simple steps to lower your chances for a blood clot:

Exercise your lower leg muscles if you re sitting for a long time while traveling.
Get out of bed and move around as soon as you re able after having surgery or being ill.
The more active you are, the better your chance of avoiding a blood clot.
Take any medicines your doctor prescribes to prevent clots after some types of surgery.
Wear compression stocking to prevent complication or recurrence as per instruction.
Keep regular follow-up with your doctor to avoid or prevent post DVT complication.
SPECIAL PRECAUTIONS FOR PEOPLE WITH DEEP VEIN THROMBOSIS:

Patients being treated for venous thrombosis are at an increased risk for developing another blood clot. The patient should watch for new onset leg pain or swelling. If these symptoms occur, the patient should speak to his/her health care provider or seek medical attention as soon as possible.
Risk of bleeding is high with anticoagulant so dose should not change unless the provider or clinic directs the patient to do so.
Patients may bleed easily from anywhere while taking anticoagulants. In some cases, bleeding can develop inside the body and can t notice immediately. Bleeding inside the body can cause a person to feel faint, or have pain in the back or abdomen. A healthcare provider should be notified immediately if there is any sign of this problem.

What is Deep Vein Thrombosis (DVT) - Symptoms,Treatment & Prevention

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?

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

Varicose veins are bulging blue veins on the legs that can cause leg swelling, skin blackening and even open wounds called ulcers. It is commonly seen in people aged 35 and above who have to stand a lot. Here are a few tips to prevent these:

1. Avoid standing for long periods: standing for long periods of time causes blood to pool in your leg veins and they begin to bulge out like a balloon. Avoid standing desks at your work. If you have to stand, take a 5-minute break every hour and walk around or sit down.

2. Keep weight in check: overweight people have a higher incidence of varicose veins. Keeping your weight in check would also prevent varicose veins.

3. Exercise 30 minutes a day: exercise, especially brisk walking or jogging, will get the blood in your leg veins to circulate and thus prevent varicose veins.

4. Take the stairs: this simple exercise activates your calf muscles and gets blood to circulate in your veins.

5. Be vigilant: calf cramps, swelling, change in colour of skin over foot and open wounds over the feet are a few signs that you need to look out for. Seek medical help to prevent worsening of this disease.

Follow these simple steps and you would be able to prevent varicose veins and have healthy feet.


5 Tips To Prevent Varicose Veins and Varicose Ulcers

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!

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.
