Coronary artery bypass graft surgery (CABG) is a procedure used to treat coronary artery disease. Coronary artery disease (CAD) is the narrowing of the coronary arteries – the blood vessels that supply oxygen and nutrients to the heart muscle. CAD is caused by a build-up of fatty material within the walls of the arteries. This build-up narrows the inside of the arteries, limiting the supply of oxygen-rich blood to the heart muscle. One way to treat the blocked or narrowed arteries is to bypass the blocked portion of the coronary artery with a piece of a healthy blood vessel from elsewhere in the body. Blood vessels, or grafts, used for the bypass procedure may be pieces of a vein from the legs or an artery in the chest. An artery from the wrist may also be used. One end of the graft is attached above the blockage and the other end is attached below the blockage. Blood is routed around, or bypasses, the blockage by going through the new graft to reach the heart muscle. This is called coronary artery bypass surgery. Traditionally, to bypass the blocked coronary artery, a large incision is made in the chest and the heart is temporarily stopped so that the surgeon can perform the delicate procedure. To open the chest, the breastbone (sternum) is cut in half and spread apart. Once the heart is exposed, tubes are inserted into the heart so that the blood can be pumped through the body by a cardiopulmonary bypass machine (heart-lung machine). The bypass machine is necessary to pump blood while the heart is stopped and kept still in order for the surgeon to perform the bypass operation. While the traditional "open heart" procedure is still commonly done and often preferred in many situations, less invasive techniques have been developed to bypass blocked coronary arteries. "Off-pump" procedures, in which the heart does not have to be stopped, were developed in the 1990's. Other minimally invasive procedures, such as keyhole surgery (performed through very small incisions) and robotic procedures (performed with the aid of a moving mechanical device), may be used.
Premature ejaculation occurs when a man ejaculates sooner during sexual intercourse than he or his partner would like. Premature ejaculation is a common sexual complaint. Estimates vary, but as many as 1 out of 3 men say they experience this problem at some time. As long as it happens infrequently, it's not cause for concern. However, you may meet the diagnostic criteria for premature ejaculation if you: Always or nearly always ejaculate within one minute of penetration Are unable to delay ejaculation during intercourse all or nearly all of the time Feel distressed and frustrated, and tend to avoid sexual intimacy as a result Both psychological and biological factors can play a role in premature ejaculation. Although many men feel embarrassed to talk about it, premature ejaculation is a common and treatable condition. Medications, counseling and sexual techniques that delay ejaculation — or a combination of these — can help improve sex for you and your partner.
A small-bowel obstruction (SBO) is caused by a variety of pathologic processes. The leading cause of SBO in industrialized countries is postoperative adhesions (60%), followed by malignancy, Crohn disease, and hernias, although some studies have reported Crohn disease as a greater etiologic factor than neoplasia.
A spinal tumor is a growth that develops within your spinal canal or within the bones of your spine. It may be cancerous or noncancerous. Tumors that affect the bones of the spine (vertebrae) are known as vertebral tumors. Tumors that begin within the spinal cord itself are called spinal cord tumors. There are two main types of tumors that may affect the spinal cord: Intramedullary tumors begin in the cells within the spinal cord itself, such as astrocytomas or ependymomas. Extramedullary tumors develop within the supporting network of cells around the spinal cord. Although they don't begin within the spinal cord itself, these types of tumors may affect spinal cord function by causing spinal cord compression and other problems. Examples of extramedullary tumors that can affect the spinal cord include schwannomas, meningiomas and neurofibromas.
During open-heart valve surgery, the doctor makes a large incision in the chest. Blood is circulated outside of the body through a machine to add oxygen to it (cardiopulmonary bypass or heart-lung machine). The heart may be cooled to slow or stop the heartbeat so that the heart is protected from damage while surgery is done to replace the valve with an artificial valve. The artificial valve might be mechanical (made of man-made substances). Others are made out of animal tissue, often from a pig.
Closure of a loop ileostomy is a relatively simple procedure although many studies have demonstrated high morbidity rates following it. Methods to reduce the number of complications, such as timing of closure or different surgical closure techniques, are investigated. The aim of this study was to evaluate the experience of the Abdominal Surgery Center at Vilnius University Hospital (VUH) ‘Santariskiu klinikos’ to review the complications after closure of loop ileostomy and to identify potential risk factors for postoperative complications.
Skin Cysts Cysts are noncancerous, closed pockets of tissue that can be filled with fluid, pus, or other material. Cysts are common on the skin and can appear anywhere. They feel like large peas under the surface of the skin. Cysts can develop as a result of infection, clogging of sebaceous glands (oil glands), or around foreign bodies, such as earrings.
In cataract surgery, the lens inside your eye that has become cloudy is removed and replaced with an artificial lens (called an intraocular lens, or IOL) to restore clear vision. The procedure typically is performed on an outpatient basis and does not require an overnight stay in a hospital or other care facility.
The hip joint is formed between the 'ball' of the femoral head and the 'socket' of the acetabulum and a cartilaginous labrum. Strong supporting muscles, the fibrous joint capsule and ischiofemoral ligament make this a stable joint. Hip dislocations are either congenital or traumatic. Congenital dislocation of the hip is caused by dysplasia of the femoral head or acetabulum and is covered in the separate article Developmental Dysplasia of the Hip. This remainder of this article deals with traumatic dislocation. Traumatic hip dislocation is an orthopaedic emergency. Large forces are required to cause hip dislocation (except in prosthetic hips) and this means that such injury may be associated with other life-threatening injuries and other fractures. The condition is extremely painful. Accurate and swift diagnosis means appropriate management can reduce morbidity.
Toxic shock syndrome is a rare, life-threatening complication of certain types of bacterial infections. Often toxic shock syndrome results from toxins produced by Staphylococcus aureus (staph) bacteria, but the condition may also be caused by toxins produced by group A streptococcus (strep) bacteria. Toxic shock syndrome historically has been associated primarily with the use of superabsorbent tampons. However, since manufacturers pulled certain types of tampons off the market, the incidence of toxic shock syndrome in menstruating women has declined. Toxic shock syndrome can affect men, children and postmenopausal women. Risk factors for toxic shock syndrome include skin wounds and surgery.
The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away.
The objective of carotid endarterectomy (CEA) is to prevent strokes. In the United States, stroke is the third leading cause of death overall and the second leading cause of death for women.[1] Among patients suffering a stroke, 50-75% had carotid artery disease that would have been amenable to surgical treatment. Several prospective randomized trials have compared the safety and efficacy of CEA with those of medical therapy in symptomatic and asymptomatic patients. Data from these prospective trials have confirmed that CEA offers better protection from ipsilateral strokes than medical therapy alone in patients presenting with either symptomatic or asymptomatic carotid artery disease.
A pancreas transplant is a surgical procedure to place a healthy pancreas from a deceased donor into a person whose pancreas no longer functions properly. Your pancreas is an organ that lies behind the lower part of your stomach. One of its main functions is to make insulin, a hormone that regulates the absorption of sugar (glucose) into your cells. If your pancreas doesn't make enough insulin, blood sugar levels can rise to unhealthy levels, resulting in type 1 diabetes. Most pancreas transplants are done to treat type 1 diabetes. A pancreas transplant offers a potential cure for this condition. But it is typically reserved for those with serious diabetes complications, because the side effects of a pancreas transplant are significant. In some cases, pancreas transplants may also treat type 2 diabetes. Rarely, pancreas transplants may be used in the treatment of pancreatic, bile duct or other cancers. A pancreas transplant is often done in conjunction with a kidney transplant in people whose kidneys have been
Barbed sutures first received US Food and Drug Administration approval for soft tissue approximation in 2005 and early adopters readily embraced this device to develop new techniques. It has become apparent that the advantages are more than just "skin deep." Superficial and deep fascia, cartilage, tendon, joint capsule, and fibrous periprosthetic capsules can also be manipulated. Barbed sutures have revolutionized our approach to facial rejuvenation and body contouring by enhancing our ability to quilt and powerfully lift tissue. The elimination of surgical drains and shorter surgical times has made this a true boon for plastic surgeons as well as many other surgical specialists. This article summarizes some of the current and evolving applications of this exciting new tool.
CPAP is a treatment that uses mild air pressure to keep your breathing airways open. It involves using a CPAP machine that includes a mask or other device that fits over your nose or your nose and mouth, straps to position the mask, a tube that connects the mask to the machine’s motor, and a motor that blows air into the tube. CPAP is used to treat sleep-related breathing disorders including sleep apnea. It also may be used to treat preterm infants who have underdeveloped lungs.
