Vascular Surgery

What is Vascular surgery?

Vascular surgery is a specialty discipline in surgery that deals with diseases of the vascular system. This is the circulatory system in the body and it comprises the blood vessels, lymph vessels, and the lymphatic system. The blood vessels include the arteries, veins, and capillaries. The arteries carry blood away from the heart while the veins carry blood to the heart. The capillaries distribute oxygen-rich blood to the body.

The lymph vessels transport the lymphatic fluid, which has blood cells. The lymphatic system draws lymph away from each part of the body. The vascular system can have problems causing diseases. These diseases affect the working of the vascular system. A vascular disease can be treated through vascular surgery.

A vascular surgeon is one who is trained in using surgical techniques to treat different kinds of vascular diseases. The vascular surgeon is responsible for the diagnosis, treatment, and overall management of all vascular diseases.

Why NH?

Narayana Institute of Vascular Sciences is Narayana Health's commitment to providing latest and world-class tertiary level vascular care, education and research to the people of India and beyond.

It is based on the principles of prevention, surgical and endovascular treatments and strict follow-up of vascular patients endeavoring to prevent strokes in high-risk groups, deaths due to Aneurysm ruptures, Limb Amputation in Diabetics and clotting in lower limb arteries and veins and their sequels.

The department performs over 1200 open and 800 endovascular procedures each year. We also perform large volumes of Aortic Aneurysm Repairs in India, both open and endovascular with results on par with the top institutes of United States of America. We have a dedicated Hybrid Operation Theatre to perform major arch, thoracic and thoracoabdominal hybrid and fenestrated graft repairs at Health City, Bangalore.

We collaborate among the different specialties dedicated to providing comprehensive and interdisciplinary care to patients with atherosclerosis, the process in which fatty materials, cholesterol, and other substances, collectively known as plaque, accumulate in the lining of an artery. When plaques become fragile and rupture, they cause blood clots that can block blood flow or break off and travel to another part of the body, causing a heart attack, limb loss or stroke.

Our Institute's emphasis on collaboration has shown to greatly improve the care patients receive allowing both established and emerging diagnostic and therapeutic methods to be applied, increasing efficiency and reducing risks to patients. Multi-disciplinary team meetings and protocol development an important part of a close partnership with specialties involved in the direct care of our vascular patients.

With the establishment of a non-invasive vascular lab at NH Health City, equipped with the latest multi-lab II and acquisition of TcPO2 machine, we are able to diagnose and treat diabetic feet with vascular compromise.

Convatec and Narayana Health have embarked on an ambitious Diabetic Wound Care and Amputation Prevention Centre at NH Health City, with the latest equipment to assess diabetic wounds and care for them.

The presence of Thrombosis Research Institute at Health City in Bangalore is a great source for detailed investigations of a cause of vascular clotting disorders and research into solutions for better vascular care in India.

Vascular Diseases

The arterial disease affects most people with age, especially in those who have high-risk factors that include patients who suffer from diabetes, high blood pressure, heart disease, a sedentary lifestyle, a family history of vascular disease (e.g. Aneurysms), poor nutritional habits or heavy smokers.

Patients with poor circulation usually have diseased arteries all over their body. Arteries usually affected are in the legs, heart, and neck. The severity of the disease and length of time it goes untreated can make a tremendous difference in the clinical outcome of a vascular disease, characterized by stroke, limb amputations, or death.

Vascular diseases can affect any of the components of the vascular system. Some of the key diseases affecting the vascular systems are:

  • Peripheral artery disease: This disease causes a blockage of arteries in the legs causing pain in the leg and obstructs circulation. It can cause sores and even lead to gangrene.
  • Renal artery disease: In this disease, the arteries in the kidney can be blocked. This can cause high blood pressure, kidney failure, and can even lead to heart failure.
  • Raynaud’s phenomenon: The arteries of the finger are affected and can cause spasms. This happens usually due to cold weather.
  • Intestinal ischemic syndrome: This is a disease where the blood vessels in the intestine are blocked. It can affect the functioning of the digestive organs.
  • Buerger’s disease: This affects arteries of the arms and legs, which may be blocked. As a result blood supply to the hands and feet can be affected leading to pain and may even cause gangrene.
  • Carotid artery disease: The carotid arteries that supply blood to the brain can be blocked. This can cause a stroke.
  • Carotid artery dissection: happens when there is a tear in a layer of the artery wall. It can cause blood leakage.
  • Carotid artery aneurysm: An aneurysm is caused when the blood vessel wall bulges, thus weakening the wall. It can even lead to a rupture of the aneurysm, which can lead to loss of consciousness.
  • Aortic aneurysm: is an aneurysm or bulge that occurs in the aorta, the main blood vessel in the heart. It can cause chest pain, breathing problems, loss of consciousness, and even death if the aneurysm bursts.
  • Varicose veins: The veins can have damaged valves and as a result, the veins bulge and appear purple. It can cause pain and swelling in the legs.
  • Spider veins: These are caused by capillary swelling, most commonly seen on the legs and feet. While they are not harmful, they may lead to bruising.
  • May-Thurner syndrome: It is also called iliac vein compression syndrome and refers to compression of the venous outflow tract in the lower extremities. It may cause swelling pain, or even lead to deep vein thrombosis.
  • Deep vein thrombosis: This is the formation of a clot in a vein, usually in the legs. Limited movement of the leg or injury can lead to the clot formation. It can cause swelling, pain, and cramps. If the clot breaks off and moves to the lungs, it can cause serious problems.
  • Pulmonary embolism: When a blood clot travels to the lungs, it causes pulmonary embolism. It can cause chest pain, breathing difficulty, and coughing up blood. If the clot is large, it can even lead to death.
  • Lymphedema: This is a condition when fluid builds up in the lymphatic system due to abnormalities. It can lead to swelling and pain. If not treated properly, it can lead to complications.

Vascular surgery treatments and procedures

The surgery and procedures involved in the treatment of vascular diseases depend on their type and severity. Narayana Health offers the following treatment options that involve making changes in lifestyle, prescribing medications as well as catheter-based endovascular methods and surgical interventions.

Lifestyle changes

Making changes in lifestyle choices and habits is the first step to deal with the problems of vascular diseases. Individuals have to quit smoking, exercise, maintain a healthy and low cholesterol diet and control diabetes.

Medications

The doctor may prescribe medications depending on the disease. Usually, medications are used to manage cholesterol and platelet function.

Minimally invasive endovascular treatment options

- Thoracic Endovascular Aortic Repair (TEVAR): It is a minimally invasive endovascular procedure used in the treatment of patients with thoracic aortic aneurysms. It can be incisionless, but a small incision is usually made in the groin to advance a catheter followed by a stent-graft to treat the aneurysm.

- Endovascular Aneurysm Repair: It follows a similar procedure like that of TEVAR and is used to effectively treat patients with the abdominal aortic aneurysm.

- Fenestrated Endovascular Aneurysm Repair: A small incision made in the groin helps in the placement of a stent-graft to preserve blood flow to the kidneys, intestines, stomach and liver.

- Angioplasty and Stenting: Here, a catheter-guided balloon is used to open a narrowed artery. Angioplasty and stenting are an effective treatment for cerebrovascular disease, vertebrobasilar diseases and peripheral arterial disease.

- Percutaneous or laser atherectomy: In this procedure, the surgeon inserts a specialised catheter into a blocked artery to get rid of the atherosclerotic plaque build-up from within the vessel.

Surgical treatments

- Open Abdominal Aortic Surgery: An abdominal incision is made to gain access to the abdominal aorta and a fabric graft is fixed into place to treat conditions like abdominal aortic aneurysm and aortoiliac occlusive disease.

- Bypass surgery: Bypass surgery is used to redirect blood flow around an area of blockage. The graft used can come from the patient’s vein or a synthetic material can be used. This surgical procedure is used to treat vertebrobasilar disease, peripheral arterial disease, renal vascular disease and mesenteric vascular disease.

- Open Carotid and Femoral Endarterectomy: The plaque build-up on the inner lining of the artery is surgically removed. The procedure is followed in the treatment of cerebrovascular disease, peripheral arterial disease and vertebrobasilar disease.

Diagnosis, treatment, and prevention of vascular diseases

Some of the ways in which vascular diseases are diagnosed include:

  • A physical examination of the affected area.
  • For peripheral artery disease, a comparison of blood pressure on the arms and ankles is done.
  • Ultrasound scanning helps the doctor to check the blood vessels and observe if there are any blockages or other problems.
  • Angiography is a common way of carrying out diagnosis of vascular diseases. Here, a dye is injected into the blood vessels. MRA or CTA scanning is then used to view the blood vessels and find out if blood flow is normal. An angiogram involves inserting a catheter into the blood vessel until it reaches the affected area and a dye is injected. This allows the doctor to diagnose and even treat the blockage through a technique known as balloon angioplasty where the blockage is removed and a stent may be inserted to prevent constriction of the blood vessel.
  • Blood tests for cholesterol and triglyceride are used to help the surgeon understand the overall health of the patient.
  • Tests may also be conducted on the heart, lungs, kidneys, and the digestive system since vascular diseases can affect the functioning of any of these organs.

The treatment for vascular diseases can involve any of the following:

  • Medications to lower cholesterol known as statins may be given to reduce the risk of strokes due to blockage.
  • Blood pressure and blood sugar levels can affect the working of the vascular system. It is important to reduce blood pressure and have normal blood sugar levels. Medication for this can be prescribed.
  • Blood thinners and other medication can be prescribed to improve the flow of blood and reduce the chances of a clot.
  • As discussed in the section on diagnosis, angioplasty is a treatment where a balloon is used to open a blocked artery and a stent fixed to ensure it remains open. This is done when there is significant blockage of the artery.
  • If there are blood clots, then medication is given to treat blood clots. This medication dissolves and breaks up the clots.

In some cases, surgery may be needed. This usually is required when blockages are too many or if medication and other treatment does not yield the desired results. Vascular surgery involves any of the following:

  • Thrombectomy is a procedure where the balloon catheter is inserted beyond the clot and then expanded and pulled back to bring out the clot.
  • Resection is a procedure where an artery that is diseased due to an aneurysm is removed and a bypass is done using a synthetic artery.
  • Aortobifemoral bypass is used to treat peripheral artery disease.
  • Varicose veins can be treated using surgery.

Vascular diseases can be prevented by lifestyle changes. Following a healthy lifestyle reduces the risks of blockages and other problems in the vascular system. Some of the measures that can be followed are:

  • Stopping smoking, which is a main contributor to certain vascular diseases.
  • Eating a healthy diet with fruits and vegetables and less fat.
  • Exercising is important to keep the circulatory system in good working condition. It also helps to reduce weight that can, in turn, help in controlling blood sugar levels and blood pressure.
  • Proper care of the hands and feet is needed as some vascular conditions can lead to gangrene.
  • Regular health checkups can ensure any problem is detected at an early stage.

Vascular surgery FAQ's

What does vascular surgery involve?

Vascular surgery is a subspecialty that deals with diseases of the vascular system; this includes the arteries, veins, and lymphatic circulation. The diseases are managed by medical therapy and minimally invasive catheter procedures. Vascular surgery involves various techniques such as balloon angioplasty, stenting, graft placement, and vascular reconstruction.

The surgery is an amalgamation of general and cardiac surgery that is pioneered by interventional radiology and includes minimally invasive techniques. Vascular surgery also deals with diagnosing and managing various conditions that affect the arteries, blood and lymphatic circulation, and veins.

Is vascular surgery painful?

Vascular surgery may be risky, as is any surgery that involves the chest, but the surgery itself is not as painful as experiencing vascular pain. This includes poor circulation, heaviness in specific areas of the body, pain, and so on. Vascular surgery is needed if the patient develops any interruption in blood flow to the tissues, organs, and nerves.

Patients who smoke, have consistently high blood pressure, are prone to chronic kidney and lung problems, and other illnesses are at a higher risk of complications, and they may find the post-surgery recovery process painful.

Why would you need vascular surgery?

Vascular surgery is usually for people above the age of 55 who suffer from vascular conditions (affecting the veins and arteries). Vascular surgeons are consulted to treat a range of conditions ranging from varicose veins to aneurysms. If you need vascular surgery, then it’s likely that you are referred to a surgeon who will provide you with further diagnosis and a treatment plan as well. The surgeon will provide you with exercise plans, and also encourage you to follow a healthy lifestyle. They will recommend surgery only if the diagnosis is severe and cannot be cured with therapy. So, the earlier you can address the issue, the more successful the treatment.

How long does it take to recover from vascular surgery?

The recovery time for vascular surgery depends on the type of surgery you’re having and other factors as well. This is because some surgeries can be more intense and require 24 hours in intensive care, and the patient will have to recover in the hospital for ten days; if the patient experiences any complications during recovery, then the stay period will increase.

The medicines that are used during recovery are as follows:

  • Aspirin for pain
  • Statins to stabilize cholesterol levels
  • Medications to lower blood pressure
  • Medicines to control blood sugar

    What are the symptoms of vascular problems?

    The symptoms for vascular problems depends on the disease; some of the prominent symptoms are as follows:

    • Heart attack
    • Stroke
    • Kidney blockage
    • High blood pressure
    • Painful cramps that can lead to ulcers
    • Numbness
    • Twitching
    • Cramps

    What are some examples of vascular disease?

    Peripheral artery disease:

    Coronary arteries are responsible for supplying blood to your heart, and they carry blood to various other tissues and organs in the body too. If the arteries have fat, cholesterol, and plaque buildup on their walls. overtime, they can narrow the vessel and reduce blood circulation this is called peripheral artery disease.

    Aneurysm:

    An aneurysm is a bulge that is formed within the wall of the blood vessel, and it mostly occurs in the aorta, chest, and abdomen. The bulge caused by an aneurysm can be deadly if it bursts under stress.

    Buerger’s disease:

    This disease is quite rare and tends to affect the small and medium-sized arteries and veins that are present in your legs and arms. The disease causes the arteries and veins to swell up and form clots that block circulation to your fingers, hands, toes, or feet. This will cause pain, even when you’re not moving.

    What is the main cause of vascular disease?

    The various causes of vascular diseases are:

    • Tiny debris that blocks the functions of a blood vessel or a blood clot. The debris is usually a tiny mass that moves through the bloodstream.
    • Blood vessel inflammation, also known as vasculitis, can lead to a variety of disorders. Inflammation can also lead to the narrowing of arteries and veins.
    • Injury caused by physical trauma can lead to damaged blood cells, which can cause infections or inflammation.

    What is the scope of vascular surgery?

    Vascular surgery involves treatment and management of diseases that affect the arteries, veins, lymphatic system, and capillaries. The vascular surgeon not only carries out surgery but also treats patients with vascular disorders with non-surgical treatment procedures.

    Who should see a vascular surgeon?

    Anyone suffering from vascular diseases would need to see a vascular surgeon. Any diseases of the blood vessels like peripheral artery disease, renal artery disease, carotid artery disease, varicose veins, spider veins, May-Thurner syndrome, blood clots, aortic aneurysms and lymphedema can be treated by a vascular surgeon. In most of these cases, a patient may see a general physician or any other doctor and may be referred to a vascular surgeon.

    Are there any risks in vascular surgery?

    Surgeries always involve an element of risk. This is more so in the case of vascular surgeries since the surgery is done on the blood vessels. Risks like bleeding, and stroke exist but in the hands of a competent vascular surgeon, these risks can be minimized. The risks are more for those who smoke, have high blood pressure, or any lung and kidney diseases.

    Do all vascular diseases require surgery?

    No, all vascular diseases do not need surgery. It is only when the disease has advanced and is not possible to treat by other ways that a surgery is performed. A vascular surgeon does not carry out surgeries but diagnoses the problem and treats it using medication and other means. Surgery may not be needed in all cases. Vascular surgery is not complicated and many of the procedures are simple and do not cause too much discomfort for the patients.
