They connect the veins outside the cranium to the venous sinuses inside the cranium.VentriculostomyLiver abscessParapneumonic effusionDense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.XYZ file format: The XYZ file format is a chemical file format. There is no formal standard and several variations exist, but a typical XYZ format specifies the molecule geometry by giving the number of atoms with Cartesian coordinates that will be read on the first line, a comment on the second, and the lines of atomic coordinates in the following lines.TamponadeHydrocephalusLumbar lymph trunk: The lumbar trunks are formed by the union of the efferent vessels from the lateral aortic lymph glands.Klinikum GroßhadernMitrofanoff principle: In urology, the Mitrofanoff principle is the creation of a passageway for urine or enema fluid that, by its (surgical) construction, has a valve mechanism to allow continence.Balloon catheter: A balloon catheter is a type of "soft" catheter with an inflatable "balloon" at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.Endoscopy unit: An endoscopy unit refers to a dedicated area where medical procedures are performed with endoscopes, which are cameras used to visualize structures within the body, such as the digestive tract and genitourinary system. Endoscopy units may be located within a hospital, incorporated within other medical care centres, or may be stand-alone in nature.JejunostomyPneumobilia: Pneumobilia is the presence of gas in the biliary system. Causes include a biliary-enteric anastomosis, an incompetent sphincter of Oddi and spontaneous biliary-enteric fistula.Percutaneous transhepatic cholangiographyPrimary lymphedema: Primary lymphedema is a form of lymphedema which is not directly attributable to another medical condition.LymphoceleEuropac: EUROPAC, the European Registry of Hereditary Pancreatic Diseases was established in 1997 by a collaboration of pancreas surgeons from Liverpool, UK.Cholangiocyte: Cholangiocytes are the epithelial cells of the bile duct. They are cuboidal epithelium in the small interlobular bile ducts, but become columnar and mucus secreting in larger bile ducts approaching the porta hepatis and the extrahepatic ducts.Empyema: An empyema (from Greek ἐμπύημα, "abscess") is a collection or gathering of pus within a naturally existing anatomical cavity. For example, pleural empyema is empyema of the pleural cavity.Hollander beater: A Hollander beater is a machine developed by the Dutch in 1680 to produce paper pulp from cellulose containing plant fibers. It replaced stamp mills for preparing pulp because the Hollander could produce in one day the same quantity of pulp it would take a stamp mill eight days to prepare.Pyogenic liver abscessChylothoraxCommon bile duct: The common bile duct (), sometimes abbreviated CBD, is a tube-like anatomic structure in the gastrointestinal tract of organisms that have a gall bladder. It is formed by the union of the common hepatic duct and the cystic duct (from the gall bladder).Debridement (dental)HemothoraxList of eponymous surgical procedures: Eponymous surgical procedures are generally named after the surgeon or surgeons who performed or reported them first. In some instances they are named after the surgeon who popularised them or refined existing procedures, and occasionally are named after the patient who first underwent the procedure.PancreatitisRe-sublimityVideo-assisted thoracoscopic surgery: Video-assisted thoracoscopic surgery (VATS) is a type of thoracic surgery performed using a small video camera that is introduced into the patient's chest via a scope. The surgeon is able to view the instruments that are being used along with the anatomy on which the surgeon is operating.Stillwater Mining Company: Stillwater Mining Company () is a palladium and platinum mining company with headquarters located at Billings, Montana, United States. It is the only palladium and platinum producer in the USA.Psoas muscle abscessBeck's triad (cardiology): Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, an emergency condition wherein fluid accumulates around the heart and impairs its ability to pump blood. The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds.PleurodesisChamber reamer: A chamber reamer is a specific type of fluted reamer used by gunsmiths and firearms manufacturers to cut the chamber of a handgun, rifle, or shotgun. The chamber reamer is inserted into the bore of a barrel and held stationary while the barrel is turned around it (typically by means of a lathe).Percutaneous: In surgery, percutaneous pertains to any medical procedure where access to inner organs or other tissue is done via needle-puncture of the skin, rather than by using an "open" approach where inner organs or tissue are exposed (typically with the use of a scalpel).Biliary tract: The biliary tract, (biliary tree or biliary system) refers to the liver, gall bladder and bile ducts, and how they work together to make, store and secrete bile. Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin.Pancreatic duct: The pancreatic duct, or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct), is a duct joining the pancreas to the common bile duct to supply pancreatic juices which aid in digestion provided by the exocrine pancreas. The pancreatic duct joins the common bile duct just prior to the ampulla of Vater, after which both ducts perforate the medial side of the second portion of the duodenum at the major duodenal papilla.Cerebral arteriovenous malformationKlatskin tumorLymphangionCholangiocarcinomaList of people with paraplegia: This is a list of people who have or had paraplegia.Bile: Bile or gall is a dark green to yellowish brown fluid, produced by the liver of most vertebrates, that aids the digestion of lipids in the small intestine.

The fat is butter in French cuisine, but may be lard or vegetable oil in other cuisines.HydrothoraxFalx cerebri: The falx cerebri is also known as the cerebral falx, named from its sickle-like form. It is a large, crescent-shaped fold of meningeal layer of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.
