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?

An abnormal swelling in the neck can be symptom of various problems. While it can be something as non-threatening as a swollen gland due to a cold that can be cured with simple medication, a swollen neck can also turn out to be a cancerous lump in the neck. When faced with an irregular swelling in the neck, it is best to not panic or jump to conclusions until you consult with an Ear-Nose-Throat Specialist. The possible problems that a swelling in the neck can indicate are:

Swelling or enlargement of the salivary glands: The salivary glands may become enlarged due to an infection or due to foreign materials getting stuck in them. While foreign objects or formation of stones in the salivary glands might require surgical removal, they can often be dissolved with medication and other non-invasive treatments. And infection in the salivary glands is often treated with antibiotics or other medication. These treatments can be prescribed and administered by ENT Specialists.
Thyroid disease: The thyroid gland may swell up and cause a swelling of the neck. These are often called goiters in colloquial language and are a result of thyroid diseases such as hypothyroidism and hyperthyroidism. They usually require a series of medication and treatment and are not considered an ENT problem despite the swelling of the neck.
Benign cysts: Benign cysts can form in any part of the neck or in the glands, much like it can form in any part of the body. An ENT Specialist can prescribe a surgical removal of the cyst lest it turns cancerous later in life. It should also be removed in case it grows or relocates, going on to cause other problems.
Lumps in the muscles: Lumps in the neck muscles are formed by injury or torticollis. These usually aren t considered ENT problems and can be treated by general physicians and sometimes chiropractors.
Cancerous cysts or growths: One of the most daunting problems posed by a swelling of the neck is the possibility of cancer. While thyroid cancers as well as cancerous growths in the salivary glands are slow to develop, a swelling in the neck should immediately be investigated by an ENT Specialist in order to rule out all possibilities.

Neck Swelling - When It's An ENT 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.

Inflammation or soojan in the body can make it difficult for you to follow your daily routine. According to Ayurveda, this is caused by an imbalance of the pitta dosha. As the pitta dosha increases, the heat in the body also increases leading to inflammation and other issues. To reduce the pitta dosha, one must consume foods that are not hot or warm in nature and increase the consumption of foods that have a cooling effect. 

7 amazing foods that can really help:

Turmeric: Turmeric contains an important anti-inflammatory compound known as curcumin. This can help reduce inflammation associated with arthritis, arteriosclerosis, asthma, and cancer. It also reduces the effects of inflammatory oxidants such as nitric oxide. Turmeric can be used to flavor foods or steeped into a tea.
Flax: Nuts such as flax and pumpkin seeds are rich in Omega-3 fatty acids. They also help cool the body. Some other nuts and seeds that you could include in your diet are almonds that have been soaked in water overnight and peeled, sunflower seeds, coconut and popcorn without salt. Avoid nuts such as brazilian nuts, chia seeds, cashew nuts, walnuts and sesame seeds as they can increase body temperature.
Garlic: Garlic is a wonder food that is very important in a pitta pacifying diet. Along with other nutrients, garlic contains allicin that has strong anti-inflammatory properties. Consuming garlic on a regular basis can also help protect a person against heart diseases by reducing inflammation in the veins and arteries.
Ginger: According to Ayurveda, ginger is considered as an universal medicine. This herb has anti-inflammatory properties that help reduce inflammation. It also aids in digestion and promotes healthy blood circulation. The best way to consume ginger to fight inflammation is to steep it in a tea.
Whole grains: To reduce the pitta dosha, you should include plenty of dry, sweet whole grains in your diet. This includes barley, oats, quinoa, wheat and rice. These foods are good sources of fiber and proteins. They also have a low glycemic index and help maintain body temperature.
Leafy vegetables: Vegetables that reduce the pitta dosha are usually sweet and astringent. These vegetables are best eaten raw at mid-day when the digestive system is functioning at its peak. Lettuce, kale, leeks, collard greens and wheat grass are some of the vegetables that you must include in your diet. On the other hand, avoid spicy vegetables like green chillies, onions, and radishes.
Tomatoes: Tomatoes contain lycopene that helps reduce inflammation in the lungs. This vegetable can be consumed raw or juiced but when cooked, the lycopene amount increases. However, avoid raw tomatoes as they can irritate the digestive system.

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. 

Leg Bypass - Know More About It!

Peripheral vascular disease (PVD) is a circulation issue that affects the veins and blood vessels outside of the brain and heart. PVD commonly strikes the veins that supply blood to the arms, legs, and organs situated beneath the stomach. These are the veins that are located away from the heart. They are known as peripheral vessels.

In PVD, the width of the veins get limited. Narrowing is normally created by arteriosclerosis. Arteriosclerosis is a condition where plaque develops inside a vessel. It is additionally called 'solidifying of the arteries'. Plaque acts towards reducing the amount of blood and oxygen that is supplied to the arms and legs. As the plaque development advances, clumps may develop, which may further affect the vessel.

There are two main types of PVDs:

    Functional PVD: This doesn't include physical issues in the veins. It causes accidental side effects. Typically,these fits happen suddenly.
    Organic PVD: This includes changes in the vein structure. This sort of PVD causes irritation, tissue harm, and blockages.

The most well-known reasons for functional PVDs are as follows:

    Emotional stress
    Smoking
    Cold temperatures
    Operating Vibrating machinery

The common causes of such natural PVDs are given below:

    Smoking
    High circulatory strain
    Diabetes
    High cholesterol

The symptoms include the following:

    Cramps
    Achiness
    Fatigue
    Burning

Diagnosis:

PVD can be diagnosed using interventional radiology (IR).

IRis a sub-claim of radiology that gives an image-guided diagnosis, and if required, includes treatment of the organs as well.It has developed as a first-line treatment in the administration of PVD.

Advantages:

IR medications are for the most part less demanding for patients than surgery, since they include no surgical cut.They are less painful and have shorter stays at the hospital. By and large, the patients are discharged on the same day the procedure is done. This mainly includes angioplasty and stenting. The procedure is as follows:

    Utilising imaging for direction, the interventional radiologist puts a catheter through the femoral artery in the crotch to the blocked vein in the legs.
    At that point, the interventional radiologist expands a balloon to open the vein that is blocked.
    Sometimes it is opened with a tiny metallic cylinder called astent.
    This is a treatment that does not require surgery; only a scratch in the skin the extent of a pencil tip.

Alternative measure:

Angioplasty and stenting have totally replaced invasive surgical methods. Early trials have proven IR to be as successful as surgery for some blood vessel and artery impairments. Earlier, extensive clinical experience demonstrated that stenting and angioplasty are favoured as first-line treatments for more procedures all through the body .

Doctors as well as patients who have been through the same, believe that IR is much better for PVD than invasive surgery, since it reduces the risk of infection.
