  2. Extravasation - Wikipedia

    en.wikipedia.org/wiki/Extravasation

    Extravasation of irrigation fluid is the unintended migration of irrigation fluid (e.g., saline) introduced into a human body.This may occur in several types of endoscopic surgery, such as minimally invasive orthopedic surgery, i.e., arthroscopy, TURP (trans-urethral resection of the prostate), and TCRE (trans-cervical resection of the endometrium).

  3. 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 ...

  4. Contrast CT - Wikipedia

    en.wikipedia.org/wiki/Contrast_CT

    However, there are no absolute contraindications to iodinated contrast, so the benefits needs to be weighted against the risks. [14] As with CT scans in general, the radiation dose can potentially increase the risk of radiation-induced cancer. The injection of iodinated contrast agents may sometimes lead to its extravasation. [15]

  5. Extravasation (intravenous) - Wikipedia

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

    Extravasation is the leakage of intravenously (IV) infused, and potentially damaging, medications into the extravascular tissue around the site of infusion. The leakage can occur through brittle veins in the elderly, through previous venipuncture access, or through direct leakage from wrongly positioned venous access devices.

  6. Pyelogram - Wikipedia

    Also, the iodinated contrast medium used in contrast CT and contrast radiography can cause allergic reactions, including severe ones. [5] The contrast dye may also be toxic to the kidneys . [ 7 ] Because a cannula is inserted, there is also a risk of a cannula site infection , that may cause fevers or redness of the cannula area.

  7. Computed tomography angiography - Wikipedia

    en.wikipedia.org/wiki/Computed_tomography...

    A reaction may occur whenever iodine contrast is injected. These reactions range in severity and it is difficult to predict if they will occur. With the current practice of using low-osmolar contrast these adverse reactions only occur in ~0.1% of cases. [4] The severity of the reaction can be broken down into three groups:

  8. Contrast agent - Wikipedia

    en.wikipedia.org/wiki/Contrast_agent

    A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. [1] Contrast agents absorb or alter external electromagnetism or ultrasound , which is different from radiopharmaceuticals , which emit radiation themselves.

  9. Radiocontrast agent - Wikipedia

    en.wikipedia.org/wiki/Radiocontrast_agent

    Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
