Some issues Dr. Nishita N. Kothary, MD can help you with:

Angioplasty

Angioplasty is a common, minimally invasive procedure performed to restore blood flow in arteries and veins that have become narrowed or blocked. Age or illness can cause plaque to build up at certain spots within the veins and arteries, and if enough collects, it can restrict the flow of blood. Angioplasty uses a tiny balloon at the end of a small, flexible tube to inflate within the narrowed section and open it up again.

Angioplasty may be performed in several different areas of the body and for a variety of reasons, most often:

Peripheral arterial disease, which reduces blood flow in the arms or legs
Atherosclerosis, or general hardening of the arteries
Carotid artery stenosis, or narrowing of the arteries in the neck that supply the brain
Coronary artery disease, or narrowing of the arteries near the heart
Renal vascular hypertension, or narrowing of the arteries in the kidney, leading to increased blood pressure

During angioplasty, a patient is given a sedative while lying on a table under an x-ray machine. A catheter (a thin, flexible, and hollow tube) is inserted into the patient's skin in the arm or groin and guided into the blocked artery. Dye is injected via the catheter, and x-rays are used to position the tip of the catheter exactly at the blockage. The tiny balloon is guided through the catheter and inflated with saline. It pushes the plaque out of the way, squishing it against the walls of the artery. The balloon may be inflated and deflated several times to let blood pass by. A stent, a tiny tube of metal mesh like a spring, may be inserted to help keep the artery open. Then the x-ray is used again to check that blood is flowing properly, the catheter is removed, and the tiny incision is bandaged.

There are no nerves within veins and arteries, so an angioplasty is generally not painful. However, there may be some discomfort at the site of the incision and when the balloon is inflated. Overall, angioplasty is a very effective and low-risk procedure, useful for helping patients avoid more difficult bypass surgery.

Lung Issues

Every cell in the body requires oxygen to function and produces carbon dioxide as a waste product. In order to keep the body's tissues constantly supplied with fresh oxygen and to keep waste from building up, the lungs pump air in and out, even while sleeping or unaware. Unfortunately, diseases and disorders affecting the lungs are some of the most common medical problems afflicting people around the world. Some of the most common lung problems include asthma, COPD, pneumonia, and lung cancer.

Asthma is a chronic disease where swollen, inflamed airways make it hard to breathe. It is often brought on by specific triggers. While asthma is a common condition, affecting millions of people, it can also be serious and even fatal in severe cases. Treatment involves avoiding triggers and using inhaled corticosteroid medications.

COPD, or Chronic Obstructive Pulmonary Disease, is the name given to two illnesses that both cause difficulty breathing: emphysema and chronic bronchitis. In emphysema, the air sacs of the lungs become damaged, while with bronchitis they become clogged with mucus. COPD is the fourth leading cause of death in the United States. It is almost always caused by breathing irritants into the lungs, such as smoking or heavy pollution.

Pneumonia is a lung infection that can be caused by bacteria, a virus, or fungi. Most healthy people recover from pneumonia in a week or two, but for some people pneumonia can be fatal. There are treatments available for pneumonia, but the best treatment is to prevent getting sick in the first place. People who are at risk should make sure they get a flu shot every year. There is also a vaccine available for the type of bacteria that causes pneumonia.

Lung cancer occurs when abnormal cells inside the lung grow into a tumor, destroying healthy tissue. Because it is so difficult to detect lung cancer in early stages when it has few symptoms, it is the deadliest form of cancer, responsible for the most cancer deaths both in the U.S. and worldwide. Most lung cancer is caused by exposure to tobacco smoke, but between 10-15% of cases are not linked to smoking.

Some problems with the lungs are minor and are not cause for concern. However if symptoms have lasted for a month or more, even if they are minor, it is worth checking with a healthcare professional. A cough, shortness of breath, or excess mucus production that lingers for weeks are all worth getting looked at.

Radioembolization (Selective Internal Radiation Therapy)

Radioembolization, or selective internal radiation therapy (SIRT), is a minimally invasive procedure that uses radiation to treat liver tumors. By targeting the hepatic artery, or the main blood vessel that supplies the liver, radioembolization can cut off the blood supply to liver tumors. The tumors shrink, and minimal damage is done to healthy tissue. Radioembolization is a treatment option for tumors that cannot be removed by surgery or other radiation therapies, for liver cancer that is confined to the liver, or for liver cancer patients that have more than 3 months of life expectancy.

To perform radioembolization, a catheter is inserted into an artery in the groin and threaded to the liver. Radioactive beads, or pellets, are delivered through the catheter. The pellets will continuously deliver radiation for 10-14 days. The pellets will remain in the body permanently without causing any complications. If the tumor or cancer is confined to one portion of the liver, radioembolization will be performed in one treatment session. If both sides of the liver are affected, a second treatment session will be done about 8 weeks after the first.

Typically, most patients can return home and do light activity within hours following the procedure. Patients will be given medication to treat any possible side effects, which can include nausea, fever, abdominal pain, or tiredness.
