Discharge or escape, as of blood from the vein into the surrounding tissues.
The act of escaping from a vessel into the tissues as associated with blood, lymph, or serum.
Seepage of fluid.
A situation where a bodily fluid, such as blood or secretions, escapes into tissue.
Leakage of fluid (e.g., blood) to the tissues out-side the vessel normally containing it; this may occur in injuries, burns, and allergic reactions.
Damage to tissue of the vein and surrounding structures when a chemotherapeutic drug leaks into the soft tissue surrounding the infusion site.
The leakage and spread of blood or fluid from vessels into the surrounding tissues, which follows injury, bums, inflammation, and allergy.
An escape of fluid from the vessels or passages which ought to contain it. Extravasation of blood due to tearing of vessel walls is found in strokes, and in the commoner condition known as a bruise. Extravasation of urine takes place when the bladder or the URETHRA is ruptured by a blow on the abdomen or on the crutch (PERINEUM), or is torn in a fracture of the pelvis. Intravenous infusions frequently extravasate.
The escape of fluid from its physiologic contained space, e.g., bile, blood, cerebrospinal fluid, into the surrounding tissue.
Extravasation refers to the escape and diffusion of fluids, typically from blood vessels or lymph vessels, into the adjacent tissues. This phenomenon can occur due to various reasons, such as injuries, burns, and inflammation.
