It involves placing a small, expandable tube called a stent in the narrowed artery. This procedure is also called carotid angioplasty and stenting. There are two carotid arteries-one on each side of the neck-that supply blood to the brain. These arteries can be narrowed and damaged by fatty deposits called plaque.
The thyroid is a butterfly-shaped gland that sits low on the front of the neck. Your thyroid lies below your Adam’s apple, along the front of the windpipe. The thyroid has two side lobes, connected by a bridge (isthmus) in the middle. When the thyroid is its normal size, you can’t feel it.
Heart failure can be ongoing (chronic), or your condition may start suddenly (acute). Heart failure signs and symptoms may include: Shortness of breath (dyspnea) when you exert yourself or when you lie down Fatigue and weakness Swelling (edema) in your legs, ankles and feet Rapid or irregular heartbeat Reduced ability to exercise Persistent cough or wheezing with white or pink blood-tinged phlegm Increased need to urinate at night Swelling of your abdomen (ascites) Sudden weight gain from fluid retention Lack of appetite and nausea Difficulty concentrating or decreased alertness Sudden, severe shortness of breath and coughing up pink, foamy mucus Chest pain if your heart failure is caused by a heart attack
Ventricular fibrillation is a heart rhythm problem that occurs when the heart beats with rapid, erratic electrical impulses. This causes pumping chambers in your heart (the ventricles) to quiver uselessly, instead of pumping blood. Sometimes triggered by a heart attack, ventricular fibrillation causes your blood pressure to plummet, cutting off blood supply to your vital organs. Ventricular fibrillation, an emergency that requires immediate medical attention, causes the person to collapse within seconds. It's the most frequent cause of sudden cardiac death. Emergency treatment includes cardiopulmonary resuscitation (CPR) and shocks to the heart with a device called a defibrillator. Treatments for those at risk of ventricular fibrillation include medications and implantable devices that can restore a normal heart rhythm.
Liddle syndrome is an inherited form of high blood pressure (hypertension). This condition is characterized by severe hypertension that begins unusually early in life, often in childhood, although some affected individuals are not diagnosed until adulthood. Some people with Liddle syndrome have no additional signs or symptoms, especially in childhood. Over time, however, untreated hypertension can lead to heart disease or stroke, which may be fatal.
Acromegaly is usually caused by a noncancerous tumor. Middle-aged adults are most commonly affected. Symptoms include enlargement of the face, hands, and feet. Prompt treatment is needed to avoid serious illness. Drugs can reduce the effects of growth hormone. If needed, surgery and radiation may be used to remove tumor cells.
A cervical rib in humans is an extra rib which arises from the seventh cervical vertebra. Sometimes known as "neck ribs", their presence is a congenital abnormality located above the normal first rib. A cervical rib is estimated to occur in 0.2% (1 in 500 people) to 0.5% of the population.
Septoplasty (SEP-toe-plas-tee) is a surgical procedure to correct a deviated septum — a displacement of the bone and cartilage that divides your two nostrils. During septoplasty, your nasal septum is straightened and repositioned in the middle of your nose.
Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve). As a result, air accumulates and compresses the lung, eventually shifting the mediastinum, compressing the contralateral lung, and increasing intrathoracic pressure enough to decrease venous return to the heart, causing shock. These effects can develop rapidly, particularly in patients undergoing positive pressure ventilation.
Priapism is a prolonged erection of the penis. The persistent erection continues hours beyond or isn't caused by sexual stimulation. Priapism is usually painful. Although priapism is an uncommon condition overall, it occurs commonly in certain groups, such as people who have sickle cell anemia. Prompt treatment for priapism is usually needed to prevent tissue damage that could result in the inability to get or maintain an erection (erectile dysfunction). Priapism is most common in men in their 30s.
