Some issues Dr. Daniel Yung-Ho Sze, PhD, MD can help you with:

Angiogram (Angiography)

Angiography is the use of x-rays to examine blood vessels, especially in order to identify any blocked or misshapen vessels that may cause problems. The test itself is called an angiogram. Some of the disorders that angiograms can be used to diagnose include:

Blockages and narrowing
Weakened walls and bulging, called an aneurysm
Malformations and misshapen blood vessels
Kidney artery conditions
Aorta artery conditions
Vein problems, including deep vein thrombosis (DVT) and blood clots or embolisms

During an angiogram, the doctor inserts a very thin, flexible tube called a catheter into a blood vessel through an opening in the groin or arm. The catheter is threaded through the body to the site of the suspected problem, where a small amount of dye is injected into the bloodstream and x-rays are taken. The dye makes the surrounding blood vessels visible via x-ray.

If necessary, certain procedures can be performed after an angiogram while the catheter is in place. Angioplasty is the use of a catheter to widen narrowed or blocked arteries. Stents are like tiny coiled springs that hold blood vessels open, and they can be placed during a catheterization. Damaged heart valves can also be repaired or replaced.

A typical angiogram takes about an hour to perform, but it may be longer if the catheterization is used to perform procedures on the blood vessels. It may be uncomfortable at times but is usually not painful. Afterwards, patients may be monitored for up to six hours to make sure any bleeding from the insertion site has stopped. They are given fluids to help flush the dye from their body. For a day or two after an angiogram it is important for patients to drink plenty of fluids and keep strenuous activity to a minimum.

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.
