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?

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

Varicose veins are abnormal veins that usually appear as bulging, twisting, rope-like cords in the lower extremity. It is a very common condition, nearly affecting 25% of men and 40% women. Varicose veins occur when the valves in the veins do not properly function. As a result, blood cannot flow effectively.

Risk Factors

A number of factors can put you at risk of developing varicose veins. These may include  

  Heredity
  Gender
  Pregnancy
  Age
  Prolonged standing
  Obesity

Symptoms Associated with Varicose Veins

For many people, varicose veins develop without revealing any symptom. However, others may experience the following signs  

  Visible purple veins
  Heaviness in the calves
  Swelling and tenderness
  Leg tiredness
  Pain
  Blood clots

If the condition deteriorates, you may also encounter symptoms like  

  Ankle sores
  Skin ulcers
  Bleeding

If you have a severe case, your veins may rupture. Therefore, consult a doctor and get the condition treated before it worsens.

Treating Varicose Veins with Radiology

If conservative techniques   compression stockings, lifestyle changes, and others   fail to relive the symptoms or cure the condition, your doctor may recommend radiofrequency ablation for varicose veins.
Radiofrequency ablation involves using heat from an electric current produced by a radio wave to remove the damaged tissues. The procedure takes place in a hospital or a clinic under the supervision of a radiologist.
The specialist will first prep you up for the procedure   the appropriate leg will be prepared using sterile technique and you will be given local anaesthesia. Ablating the veins using laser takes only about a few minutes. Once the procedure is completed, the patient may be kept under observation briefly before being let off. However, he/she might have to wear a special compression stocking, as prescribed by the doctor, to speed up healing.

Varicose veins typically deteriorate over time despite making necessary lifestyle changes for pain management. The minimally invasive radiofrequency ablation procedure is an effective treatment for a condition as painful as varicose veins. It is safer than surgery with minimal risks. Since it is an outpatient procedure, the patient is allowed to walk away the same day.

Varicose Veins - Know All About Them!

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!

Every woman wishes for great legs they can flaunt in tiny shorts and skirts whenever they feel like it. The greatest impediment to this freedom, however, is unattractive spider and varicose veins that make legs lose their aesthetic value and limit women from enjoying experimenting with short outfits. Not only do these veins look unattractive on legs, but they are quite painful as well. The good news is that modern medicine has enabled doctors to use the body's own healing mechanisms to amend the problem. Doctors can now employ the use of laser treatments and injections to provide quick relief to patients. What's more, these treatments can be addressed easily in a doctor's office and require short visits, and you can walk comfortably out of the doctor's office on your own.

How it works
Minimally invasive laser treatments and injections are used to collapse and then shrink the affected veins. Thereafter, the veins are then absorbed into the tissue that underlay this, and will bring a clear effect such that all the visible traces will be gone. The surrounding healthy veins will then take control and restore the normal circulation of the body. While there might be some little bruising noticed, it will only last temporarily.

Options available
Today the treatments for these veins are improved and what's more, the process is much more comfortable. This is unlike the past where thick, uncomfortable, elastic compression socks were used to relieve pain and the procedures involved a surgery where veins are stripped out of the leg and patients are put under anesthetics. The options that are available today include endovenous laser ablation where a map around the abnormal vein is created with ultrasound, a catheter inserted into the vein and a laser carefully passed through the catheter generating a controlled amount of heat that will seal the vein and redirect blood to the healthy vessels. There is injection sclerotherapy where a pharmaceutical liquid is injected into the vein that will cause the vessels walls to adhere and then seal shut and the blood instantly gets directed to healthier veins while the treated vein disappears. Laser sclerotherapy is reserved for tiny superficial veins and may not get injected.

While there is no cure for varicose veins, a doctor can prescribe post treatment instructions that will minimize the chances of a patient getting the veins again. Things like managing diet, exercise and good lifestyle choices are among them. Also routine monitoring is the key to preventing future reoccurrences.

The heart pumps pure blood to all parts of the body through a network of arteries. These are thicker in the beginning and become finer and thinner as they reach the various organs. These arteries are lined by a layer of epithelial tissues and as blood flows through them, the heavier cholesterol / fat molecules settle down along the walls. 


This attracts more and more fat molecules to settle down.  This is known as atherosclerosis (hardening of the arteries). Over a period of time, the vessels circumference reduces and the blood supply to the target organ reduces. This impacts proper functioning of these organs and when this happens to the major organs like the heart, kidney or the brain, conditions like stroke or thrombosis or heart attack can occur.


This condition, known as coronary artery disease, is becoming a major cause of deaths.  While that is the bad news, the good news is that it is largely lifestyle dependent, and if steps are taken, it can be prevented, and in the early stages, the damage completely reversed.


Preventive measures: 
1. Diet: A low-fat, high-fiber, heart-healthy diet consisting of Omega-3 fatty acids is recommended by doctors, especially to people who are prone to develop heart disease.  This also requires reduced salt, increased unsaturated fats, reduced triglycerides and reduced sugar.  Include loads of fresh fruits and vegetables, whole grains, nuts and seeds and fish oils. Include multivitamins or other supplements after checking with your doctor.


2. Exercise:  Regular exercise in any form increases the efficiency of the circulatory system, keeps the cholesterol levels in check and helps in blood pressure management.  Exercise in any form is advisable, based on individual preference. A moderate physical activity of 30 to 45 minutes per day is advisable.


3. Smoking: This is one of the major risk factors for smoking, and quitting or controlling smoking is one of the best methods to prevent coronary artery disease.


4. Alcohol consumption:  While moderate alcohol consumption is believed to be healthy for the heart, excessive alcohol consumption is a strict no-no.  Binge drinking especially is shown to cause heart attacks.


5. Weight management: Check with your doctor on what is ideal BMI for you and work out a plan to keep your weight under check.


6. Regular medications: If you are on blood pressure or diabetes medications, ensure you do not miss them.  Keep a constant check to ensure your readings are managed well. 


7. Watch out:  Ask your doctor if there are specific symptoms that you need to watch out and seek medical support if you see any of them.


Coronary disease is not treatable fully, but can be prevented and managed effectively to improve the overall quality of life.
