Extravasation of medication during intravenous therapy is an adverse event related to therapy that, depending on the medication, amount of exposure, and location, can potentially cause serious injury and permanent harm, such as tissue necrosis.
This is known as leukocyte extravasation, also called diapedesis. In the case of cancer metastasis, it refers to cancer cells exiting the capillaries and entering other tissues, where secondary tumors may form. The term is commonly used in a medical context. More specifically, extravasation can refer to: Extravasation (intravenous)

Angiopellosis allows for the extravasation of multiple cells during a single event. The blood vessel will actively remodel around a cluster/group of cells and allow the cells to exit in a single event. Diapedesis only allows for a single white blood cell to migrate across the blood vessel wall at a given time.

During leukocyte extravasation, white blood cells move in response to cytokines from the blood into diseased or infected tissues, usually in the direction of a chemical gradient, [1] in a process called chemotaxis. The presence of lymphocytes in tissue in greater than normal numbers is likewise called infiltration.
