Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries). Narrowing of the arteries prevents normal amounts of oxygen-rich blood from reaching your kidneys. Your kidneys need adequate blood flow to help filter waste products and remove excess fluids. Reduced blood flow may increase blood pressure in your whole body (systemic blood pressure) and injure kidney tissue.
Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The function of pulmonary circulation is to exchange carbon dioxide for oxygen in the blood. It is the passage of blood from the heart to the capillaries of the lungs, where the gases are exchanged, and back to the heart to be pumped around the body.
Most babies will move into delivery position a few weeks prior to birth, with the head moving closer to the birth canal. When this fails to happen, the baby’s buttocks and/or feet will be positioned to be delivered first. This is referred to as “breech presentation.” Breech births occur in approximately 1 out of 25 full-term births.
When the colon and rectum are removed (due to ulcerative colitis or familial adenomatous polyposis), another reservoir must be created for bowel contents (stool) to exit the body. Surgically creating a “J” shaped reservoir (called a J-pouch) is an option for selected patients to store and pass stool.
To treat your tinnitus, your doctor will first try to identify any underlying, treatable condition that may be associated with your symptoms. If tinnitus is due to a health condition, your doctor may be able to take steps that could reduce the noise. Examples include: Earwax removal.
The typical radiograph is of a well-defined, rounded, retrocardiac opacity with an air-fluid level. In this image, the radiolucent gas is highlighted in blue, while the gastric contents are highlighted in the green. In many cases of hiatal hernia, there will not be an air bubble below the left hemidiaphragm. This is a relatively expected finding considering that the stomach is no longer in its usual position. The anatomical position of the herniated organ can be further elucidated on the lateral radiograph. Here we can see that the stomach is in the middle mediastinum posterior to the heart and above the diaphragm. Hiatal hernias can look similar to a retrocardiac lung abscess or another cavitary lesion, but it will change in size and shape between radiographs. Large hernias can shift the mediastinum to the right and result in a widening of the carinal angle. They can even give the appearance of cardiomegaly. In this radiograph, the cardiac silhouette is distinctly visible within the confines of the hiatal hernia. To review, a hiatal hernia on an AP chest radiograph typically appears as a round retrocardiac opacity with an air-fluid level.

In this animation it depicts an artery with cholesterol plaque (the yellowish area) which is blocking most of the inside of this artery. Then small cells called platelets become clumped together and cause the red blood cells to form a clot. This is what causes a HEART ATTACK.
Upper gastrointestinal bleeding (sometimes upper GI, UGI bleed, Upper gastrointestinal hemorrhage, gastrorrhagia) refers to bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. In fact, the proportion of UGIB cases caused by peptic ulcer disease has declined, a phenomenon that is believed to be due to the use of proton pump inhibitors (PPIs) and H pylori therapy. Duodenal ulcers are more common than gastric ulcers, but the incidence of bleeding is identical for both.
A Fistulotomy is the surgical opening or removal of a fistulous tract. They can be performed by excision of the tract and surrounding tissue, simple division of the tract, or gradual division and assisted drainage of the tract by means of a seton; a cord passed through the tract in a loop which is slowly tightened over a period of days or weeks.
Fistulas can occur in various areas of the human body, and the location of the fistula influences the necessity of the procedure. Some, such as ano-vaginal and perianal fistulas are chronic conditions, and will never heal without surgical intervention.
