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.
Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso. Shingles is caused by the varicella-zoster virus — the same virus that causes chickenpox. After you've had chickenpox, the virus lies inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles. While it isn't a life-threatening condition, shingles can be very painful. Vaccines can help reduce the risk of shingles, while early treatment can help shorten a shingles infection and lessen the chance of complications.
Pulmonary hypertension is a type of high blood pressure that affects the arteries in your lungs and the right side of your heart. In one form of pulmonary hypertension, tiny arteries in your lungs, called pulmonary arterioles, and capillaries become narrowed, blocked or destroyed. This makes it harder for blood to flow through your lungs, and raises pressure within your lungs' arteries. As the pressure builds, your heart's lower right chamber (right ventricle) must work harder to pump blood through your lungs, eventually causing your heart muscle to weaken and fail. Some forms of pulmonary hypertension are serious conditions that become progressively worse and are sometimes fatal. Although some forms of pulmonary hypertension aren't curable, treatment can help lessen symptoms and improve your quality of life. Pulmonary hypertension care at Mayo Clinic
To facilitate the delivery of fluids during labour, obstetric anaesthetists from Coventry designed a triple IV peripheral connector with a central high-flow anti-reflux valve. This connector, now rightly known as the Coventry valve, can be used for all theatre settings and is especially useful in obstetrics, ICU, HDU and orthopaedics. More details on www.mediplus.co.uk
Overview
Heart bypass surgery creates a new route, called a bypass, for blood and oxygen to reach the heart.
Heart bypass surgery begins with an incision in the chest, and the breastbone is cut exposing the heart. Next, a portion of the saphenous vein, which is very large, is harvested from the inside of the leg. Pieces of this large vein are used to bypass the blocked coronary arteries, which are arteries that supply blood to the heart. The venous graft is sewn to the aorta, the main artery of the body, and to the affected coronary artery, to bypass the blocked site.
The internal mammary artery from the chest may also be used to bypass a clogged artery.
Several arteries may be bypassed depending on the condition of the heart. After the graft is created, the breastbone and chest are closed.
rostbite refers to the freezing of body tissue (usually skin) that results when the blood vessels contract, reducing blood flow and oxygen to the affected body parts. Normal sensation is lost, and color changes also occur in these tissues.
Thoracic outlet syndrome is a disorders that occur when blood vessels or nerves in the space between your collarbone and your first rib (thoracic outlet) are compressed. This can cause pain in your shoulders and neck and numbness in your fingers. Common causes of thoracic outlet syndrome include physical trauma from a car accident, repetitive injuries from job- or sports-related activities, certain anatomical defects (such as having an extra rib), and pregnancy. Sometimes doctors can't determine the cause of thoracic outlet syndrome. Treatment for thoracic outlet syndrome usually involves physical therapy and pain relief measures. Most people improve with these approaches. In some cases, however, your doctor may recommend surgery.
The lymphatic system is a network of specialized vessels (lymph vessels) throughout the body whose purpose is to collect excess lymph fluid with proteins, lipids, and waste products from the tissues. This fluid is then carried to the lymph nodes, which filter waste products and contain infection-fighting cells called lymphocytes. The excess fluid in the lymph vessels is eventually returned to the bloodstream. When the lymph vessels are blocked or unable to carry lymph fluid away from the tissues, localized swelling (lymphedema) is the result.
