Related to arteriovenous fistula: Arteriovenous malformation


(fĭs`cho͝olə), abnormal, usually ulcerous channellike formation between two internal organs or between an internal organ and the skin. It may follow a surgical procedure with improper healing, or it may be caused by injury, abscess, or infection with penetration deep enough to reach another organ or the skin. When open at only one end it is called an incomplete fistula or sinus. The most common sites of fistula are the rectum and the urinary organs, but almost any part of the body may be affected. Rectal fistulas are often associated with colitis, cancercancer,
in medicine, common term for neoplasms, or tumors, that are malignant. Like benign tumors, malignant tumors do not respond to body mechanisms that limit cell growth.

, and other disorders. Usually a fistula requires surgery. In horses an abscess on the withers from chafing and infection is termed a fistula.



an abnormal passage between hollow organs or between an organ, body cavity, or focus of disease and the body surface. Usually in the form of a narrow canal lined with epithelium or granulations, it continuously discharges pus, mucus, bile, urine, or feces.

Congenital fistulas, for example, umbilical fistulas, are developmental anomalies. Acquired fistulas result from such chronic inflammations as osteomyelitis, from tumors, or from injuries. Fistulas are usually treated by surgery.

It is sometimes necessary to create artificial fistulas surgically. They may connect hollow organs, in which case they are called internal fistulas, or anastomoses. An example is gastroenteroanastomosis in cicatricial stenosis of the outlet of the stomach.

Gastrostomy is the establishment of an external fistula, or stoma, for artificial feeding. External fistulas also permit the discharge of urine or feces. For example, cystostoma is a fistula of the urinary bladder formed when the urethra is compressed by a tumor. With external fistulas, care must be taken to avoid irritating or infecting the surrounding skin.
