TranslationsExtravasation
extravasation[ik‚strav·ə′sā·shən] (geology) The eruption of lava from a vent in the earth. (medicine) The pouring out or eruption of a body fluid from its proper channel or vessel into the surrounding tissue. Extravasation the accumulation of blood that has flowed out of the blood vessels into the body cavities or surrounding tissues. Extravasation may occur when the walls of the vessels are destroyed by a mechanical injury or a pathological process (for example, tumor). It may also occur through an uninjured wall, when the permeability of the wall is increased (for example, under the influence of certain chemical substances). The discharged blood may either permeate the tissues affected by the extravasation or form a circumscribed accumulation, called a hematoma. The significance of extravasation is determined by dimensions, rapidity of development, and site of formation. When the process is minor it is resorbed without treatment. If encapsulated or suppurative, it often requires special treatment. Because extravasation may lead to the destruction of tissue, it is especially dangerous in the brain (insult). extravasation
extravasation [eks-trav″ah-za´shun] 1. a discharge or escape, as of blood, from a vessel into the tissues.2. the inadvertent administration of a vesicant into the tissues; the intensity of the irritating action is so severe that plasma escapes from the extracellular space and blisters are formed. Large extravasations of some medications may lead to contractures, with the need for débridement and grafting and in severe cases amputation. This term must be distinguished from intravenous infiltration and flare.3. blood or another substance so discharged.ex·trav·a·sa·tion (eks-trav'ă-sā'shŭn), 1. The act of extravasating. 2.
