The act of forcing or letting out of its proper vessels or ducts, as a fluid; effusion; as, an extravasation of blood after a rupture of the vessels.
extra = out + vas = vessel; leakage, e.g., of urine from urinary tract.
leaking out of fluid from the blood vessels into the tissues.
escape of fluid, especially of blood, lymph, or serum, from a vessel into tissue spaces
Movement of PMNs across blood vessel wall into tissues (Lecture: Innate Immunity and Inflammation II, 2/21/02)
the action of passing by infiltration of effusion from a blood vessel into surrounding tissues.
the process of exuding or passing out of a vessel into surrounding tissues; said or blood or lymph or urine
Leakage into the surrounding tissues of intravenous fluids or drugs -- i.e. cancer chemotherapy drugs -- from the vein being used for the infusion or injection. Extravasation may damage tissues.
slow leakage of fluid (as in extravasation of aqueous from the eye).
Escape of fluids into surrounding tissues
Leakage into the surrounding tissues of intravenous fluids or drugs, especially cancer chemotherapeutic agents, from the vein being used for injection. Extravasation may damage the tissues.
The leaking of intravenous fluids or medications into tissue surrounding the infusion site. Extravasation may cause tissue damage.
The in advertent leaking of injectable medication into tissue surrounding the infusion site. Extravasation of drugs such as doxorubicin, vincristine or vinblastine may cause tissue damage.
Leaking of the drug out of the vein and into the skin.
To exude from or pass out of a vessels into the tissues; suffusion.
Extravasation refers to the leakage of a fluid out of its container. In the case of inflammation, it refers to the movement of white blood cells from the capillaries to the tissues surrounding it. In the case of malignant cancer metastasis it refers to cancer cells exiting the capillaries and entering organs.
