  2. Extravasation - Wikipedia

    en.wikipedia.org/wiki/Extravasation

    Extravasation is the leakage of a fluid out of its contained space into the surrounding area, especially blood or blood cells from vessels. In the case of inflammation , it refers to the movement of white blood cells through the capillary wall , into the surrounding tissues.

  3. Extravasation (intravenous) - Wikipedia

    en.wikipedia.org/wiki/Extravasation_(intravenous)

    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.

  4. Leukocyte extravasation - Wikipedia

    en.wikipedia.org/wiki/Leukocyte_extravasation

    Neutrophils extravasate from blood vessels to the site of tissue injury or infection during the innate immune response.. In immunology, leukocyte extravasation (also commonly known as leukocyte adhesion cascade or diapedesis – the passage of cells through the intact vessel wall) is the movement of leukocytes (white blood cells) out of the circulatory system (extravasation) and towards the ...

  5. Inflammation - Wikipedia

    en.wikipedia.org/wiki/Inflammation

    Leukocyte extravasation [ edit ] Neutrophils migrate from blood vessels to the infected tissue via chemotaxis, where they remove pathogens through phagocytosis and degranulation Inflammation is a process by which the body's white blood cells and substances they produce protect us from infection with foreign organisms, such as bacteria and viruses.

  6. Angiopellosis - Wikipedia

    en.wikipedia.org/wiki/Angiopellosis

    Angiopellosis extravasation occurs as a means for cells that are not native to the circulation to exit. This includes adult stem cells that are injected intravenously for therapies. Cells that are normally found in circulation (i.e. blood cells ) either extravasate through diapedesis (white blood cells), or do not extravasate and remain in ...

  7. Extravasation of urine - Wikipedia

    en.wikipedia.org/wiki/Extravasation_of_urine

    An injury to the urethra leaving Buck's fascia intact results in a collection of urine (extravasation) limited to the penis, deep to Buck's fascia. If the injury to the bulb of the penis results in urethral injury accompanying a tear of Buck's fascia, then extravasated blood and urine accumulates in the superficial perineal space, passing into the penis (outer to Buck's fascia) as well as the ...

  9. Infiltration (medical) - Wikipedia

    en.wikipedia.org/wiki/Infiltration_(medical)

    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.
