Arteriovenous Fistula definition: An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
Biliary Fistula definition: Abnormal passage in any organ of the biliary tract or between biliary organs and other organs.
biliary fistula definition: abnormal passage in any organ of the biliary tract or between biliary organs and other organs.
Biliary Fistula definition: An abnormal communication between the bile ducts and another organ or cavity.
Urinary Bladder Fistula definition: An abnormal passage in the URINARY BLADDER or between the bladder and any surrounding organ.
Vesical Fistula definition: An abnormal communication between the urinary bladder and another organ or anatomic site.

Esophageal Fistula definition: An abnormal communication between the esophagus and another organ or anatomic site.
Fistula definition: Abnormal communication most commonly seen between two internal organs, or between an internal organ and the surface of the body.
Gastric Fistula definition: Abnormal passage communicating with the STOMACH.
gastric fistula definition: abnormal passage communicating with the stomach; often applied to an artificially created opening through the abdominal wall into the stomach (gastrostoma).
Gastric Fistula definition: An abnormal communication between the stomach and another organ or anatomic site.
Intestinal Fistula definition: An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).
Oroantral Fistula definition: A fistula between the maxillary sinus and the oral cavity.
Pancreatic Fistula definition: Abnormal passage communicating with the PANCREAS.
Pancreatic Fistula definition: An abnormal communication between the pancreas and another organ or cavity.
Portacaval Shunt, Surgical definition: Surgical portasystemic shunt between the portal vein and inferior vena cava.
Rectal Fistula definition: An abnormal anatomical passage connecting the RECTUM to the outside, with an orifice at the site of drainage.
Rectal Fistula definition: An abnormal communication between the rectum and another organ or cavity.
Rectovaginal Fistula definition: An abnormal anatomical passage between the RECTUM and the VAGINA.
Tracheoesophageal Fistula definition: Abnormal passage between the ESOPHAGUS and the TRACHEA, acquired or congenital, often associated with ESOPHAGEAL ATRESIA.
Urinary Fistula definition: An abnormal passage in any part of the URINARY TRACT between itself or with other organs.
Oral Fistula definition: An abnormal passage within the mouth communicating between two or more anatomical structures.
Anorectal Fistula definition: A pathologic tract that connects an opening in the anal canal to the perianal skin. In the vast majority of cases there is a history of perianal abscess.
Gallbladder Fistula definition: An abnormal communication between the gallbladder and another organ or cavity.
Enterovesical Fistula definition: An abnormal communication between the urinary bladder and the intestine.
Duodenal Fistula definition: An abnormal communication between the duodenum and another organ or cavity.
Colonic Fistula definition: An abnormal communication between the large intestine and another organ or cavity.
Cutaneous Fistula definition: An abnormal passage or communication leading from an internal organ to the surface of the body.
NEEDLE, FISTULA definition: A blood access device and accessories is a device intended to provide access to a patient's blood for hemodialysis or other chronic uses. When used in hemodialysis, it is part of an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and provides access to a patient's blood for hemodialysis. The device includes implanted blood access devices, nonimplanted blood access devices, and accessories for both the implanted and nonimplanted blood access devices. (1) The implanted blood access device consists of various flexible or rigid tubes, which are surgically implanted in appropriate blood vessels, may come through the skin, and are intended to remain in the body for 30 days or more. This generic type of device includes various shunts and connectors specifically designed to provide access to blood, such as the arteriovenous (A - V) shunt cannula and vessel tip. (2) The nonimplanted blood access device consists of various flexible or rigid tubes, such as catheters, cannulae or hollow needles, which are inserted into appropriate blood vessels or a vascular graft prosthesis (Secs. 870.3450 and 870.3460), and are intended to remain in the body for less than 30 days. This generic type of device includes fistula needles, the single needle dialysis set (coaxial flow needle), and the single needle dialysis set (alternating flow needle). (3) Accessories common to either type include the shunt adaptor, cannula clamp, shunt connector, shunt stabilizer, vessel dilator, disconnect forceps, shunt guard, crimp plier, tube plier, crimp ring, joint ring, fistula adaptor, and declotting tray (including contents).
ADAPTOR, FISTULA definition: A hemodialysis system and accessories is a device that is used as an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and that consists of an extracorporeal blood system, a conventional dialyzer, a dialysate delivery system, and accessories. Blood from a patient flows through the tubing of the extracorporeal blood system and accessories to the blood compartment of the dialyzer, then returns through further tubing of the extracorporeal blood system to the patient. The dialyzer has two compartments that are separated by a semipermeable membrane. While the blood is in the blood compartment, undesirable substances in the blood pass through the semipermeable membrane into the dialysate in the dialysate compartment. The dialysate delivery system controls and monitors the dialysate circulating through the dialysate compartment of the dialyzer. (1) The extracorporeal blood system and accessories consists of tubing, pumps, pressure monitors, air foam or bubble detectors, and alarms to keep blood moving safely from the blood access device and accessories for hemodialysis (Sec. 876.5540) to the blood compartment of the dialyzer and back to the patient. (2) The conventional dialyzer allows a transfer of water and solutes between the blood and the dialysate through the semipermeable membrane. The semipermeable membrane of the conventional dialyzer has a sufficiently low permeability to water that an ultrafiltration controller is not required to prevent excessive loss of water from the patient's blood. This conventional dialyzer does not include hemodialyzers with the disposable inserts (Kiil type) (Sec. 876.5830) or dialyzers of high permeability (Sec. 876.5860). (3) The dialysate delivery system consists of mechanisms that monitor and control the temperature, conductivity, flow rate, and pressure of the dialysate and circulates dialysate through the dialysate compartment of the dialyzer. The dialysate delivery system includes the dialysate concentrate for hemodialysis (liquid or powder) and alarms to indicate abnormal dialysate conditions. This dialysate delivery system does not include the sorbent regenerated dialysate delivery system for hemodialysis (Sec. 876.5600), the dialysate delivery system of the peritoneal dialysis system and accessories (Sec. 876.5630), or the controlled dialysate delivery system of the high permeability hemodialysis system (Sec. 876.5860). (4) Remote accessories to the hemodialysis system include the unpowered dialysis chair without a scale, the powered dialysis chair without a scale, the dialyzer holder set, dialysis tie gun and ties, and hemodialysis start/stop tray.
