Some issues Dr. John Patrick Loftus, 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.

Peripheral Bypass Surgery

Peripheral bypass surgery is a procedure that reroutes blood flow around a blockage in the arteries of the arms or legs. Atherosclerosis, or plaque buildup, can affect these arteries in a condition called peripheral artery disease or PAD. A thick, waxy substance composed of cholesterol and minerals builds up within the blood vessels, and in severe cases it can clog arteries. Without enough blood getting to the muscles, patients can experience weakness and pain. Peripheral bypass surgery opens up a new pathway for blood to flow where it is needed. Sometimes peripheral bypass surgery is used when arteries are damaged, for instance, by a severe injury. While it can be performed in the arms, it is most commonly done in the calf, knee, thigh, or hip.

During surgery, the blockage is identified, and an incision is made to expose the artery. The surgeon prepares a tube, called a graft, to be used as the bypass. Sometimes this tube is synthetic, and sometimes a piece of the patient's own vein or artery is used. The ends of the bypass graft are attached to the artery above and below the blockage. Now blood can simply flow around and continue on its way.

After a peripheral bypass, patients may need to spend a couple of days in the hospital while doctors make sure the bypass is working and not leaking. If the bypass was done in the leg, doctors may check the pulse in the feet to make sure blood is flowing well. Patients may experience some swelling in the area where they had surgery. Raising an arm or leg will help. Patients will likely be back to normal activities within 2-3 weeks.
