Coronary artery bypass grafting (CABG) is a type of surgery that improves blood flow to the heart. Surgeons use CABG to treat people who have severe coronary heart disease (CHD). CHD is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries.
Central venous access is essential in providing quality medical care to many patients for whom intensive therapy is required. In many situations, a semipermanent tunneled central line is preferred (see Indications). An anterior approach to the internal jugular vein (IJV) is the best option in this situation because it offers the easiest route with a low risk of complications. In this procedure, a tunneled catheter is surgically inserted into a vein in the neck or chest and passed under the skin. Only the end of the catheter is brought through the skin; medicines and intravenous (IV) fluid can be administered through this catheter; other tasks, such as blood sampling, can also be performed. The fact that the catheter is passed under the skin helps secure the catheter, reduces the rate of infection, and permits free movement of the catheter port. The placement of a tunneled catheter should be carried out by practitioners with specific experience in the procedure.
Papillary fibroelastoma is the third most common primary tumor of the heart and is most likely to involve the cardiac valves. Like myxomas, they arise from the endocardium in most patients and since these tumors are often incidental findings at echocardiography or autopsy, the true incidence is difficult to estimate. Most patients are older than 60 years, which also contrasts with myxomas. Papillary fibroelastomas can embolize, leading to severe neurological complications and therefore, surgical removal is advised, although there is controversy regarding small incidental lesions and the need for surgery.
Juvenile rheumatoid arthritis, also known as juvenile idiopathic arthritis, is the most common type of arthritis in children under the age of 17. Juvenile rheumatoid arthritis causes persistent joint pain, swelling and stiffness. Some children may experience symptoms for only a few months, while others have symptoms for the rest of their lives. Some types of juvenile rheumatoid arthritis can cause serious complications, such as growth problems and eye inflammation. Treatment of juvenile rheumatoid arthritis focuses on controlling pain, improving function and preventing joint damage.
Dr. Leo Maguire, a Mayo Clinic ophthalmologist, explains how laser-assisted in situ keratomileusis (LASIK) eye surgery can correct common vision problems.

Rhabdomyolysis is a condition in which damaged skeletal muscle (Ancient Greek: rhabdomyo-) tissue breaks down rapidly (Greek –lysis). This damage may be caused by physical (e.g. crush injury), chemical, or biological factors. Breakdown products of damaged muscle cells are released into the bloodstream; some of these, such as the protein myoglobin, are harmful to the kidney and may lead to kidney dysfunction. The severity of the symptoms (which may include muscle pains, vomiting and confusion) depends on the extent of the muscle damage, and whether kidney failure develops. The mainstay of treatment is generous intravenous fluids, but could include dialysis or hemofiltration.
Rhabdomyolysis and its complications are significant problems for those injured in disasters such as earthquakes and bombing. Relief efforts in areas struck by earthquakes often include medical teams with skills and equipment for treatment of survivors with rhabdomyolysis. The disease and its mechanisms were first fully elucidated during the Blitz of London in 1941.
Multicystic dysplastic kidney (MCDK) is a condition that results from the malformation of the kidney during fetal development. The kidney consists of irregular cysts of varying sizes. Multicystic dysplastic kidney is a common type of renal cystic disease, and it is a cause of an abdominal mass in infants.
Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of or treat a variety of diseases, including many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders and other abnormalities within the body.
An intracranial hematoma occurs when a blood vessel ruptures within your brain or between your skull and your brain. The collection of blood (hematoma) compresses your brain tissue. An intracranial hematoma may occur because the fluid that surrounds your brain can't absorb the force of a sudden blow or a quick stop. Then your brain may slide forcefully against the inner wall of your skull and become bruised. Although some head injuries — such as one that causes only a brief lapse of consciousness (concussion) — can be minor, an intracranial hematoma is potentially life-threatening and often requires immediate treatment. An intracranial hematoma often, but not always, requires surgery to remove the blood.
Beta-blockers, also known as beta antagonists, beta-adrenergic blocking agents, or beta-adrenergic antagonists, are drugs that are prescribed to treat several different types of conditions, including hypertension (high blood pressure), angina, some abnormal heart rhythms, heart attack (myocardial infarction), anxiety, migraine, glaucoma, and overactive thyroid symptoms.
A ganglion cyst is a tumor or swelling on top of a joint or the covering of a tendon (tissue that connects muscle to bone). It looks like a sac of liquid (cyst). Inside the cyst is a thick, sticky, clear, colorless, jellylike material. Depending on the size, cysts may feel firm or spongy.
What is idiopathic intracranial hypertension? Idiopathic intracranial hypertension (IIH) is a disorder that results from an increase in the pressure of the Cerebro-Spinal Fluid (CSF) that cushions and protects the brain and spinal cord. The CSF is constantly produced in the brain and reabsorbed back into the bloodstream at a fairly constant rate. This allows the fluid pressure around the brain to remain constant. What are the symptoms of idiopathic intracranial hypertension? Headaches that are generally nonspecific in location, type and frequency and can be associated with nausea and vomiting. Pulsatile tinnitus is a rhythmic or pulsating ringing heard in one or both ears. Horizontal double vision can be a sign of pressure on the 6th cranial nerve(s). Nonspecific radiating pain in the arms or legs (radicular pain). Transient obscurations of vision (TOV), which are temporary dimming or complete blacking out of vision. Visual field defects. These defects can occur in the central as well as the peripheral vision. Loss of color vision. What causes idiopathic intracranial hypertension? The cause is usually not known. A common explanation for increased pressure is a problem with the reabsorption of this fluid back into the body, which causes the pressure to increase. Sometimes the cause is determined and is referred to as “secondary” intracranial hypertension.
Spinal stenosis can put pressure on the spinal cord and the nerves within the spine. It commonly occurs in the neck and lower back. The condition is often caused by age-related wear and tear. Symptoms, if they occur, include pain, numbness, muscle weakness, and impaired bladder or bowel control. Treatment includes medication, physical therapy, and possibly surgery
