Extravasation
Extravasation ( Latin extra 'outside' ; vas 'vessel' ) describes in the context of so-called extravasation in the narrow sense of the word, blood that has leaked from a vein and is in the body. In a broader sense, any fluid that has leaked from the blood vessel , lymphatic vessel or urinary system , which is distributed in the surrounding tissue and leads to edematous swelling. The extravasation may contain blood cells.
Extravasation differs from exudation in that the vascular walls are whole and only part of the blood fluid exudes, but no blood globules.
In clinical medicine, the term is used to denote an injection or infusion fluid that comes next to a punctured blood vessel, see extravasation .
Extravasation is the term used in many languages, e.g. B. English or Italian, as well as those in German at the beginning of the 20th century. The current German medical terminology is an exception and calls this process extravasation .
