Blood extravasation refers to the escape or seepage of blood from blood vessels into the surrounding tissues or spaces due to the rupture or damage of these vessels. It is an abnormal condition that typically occurs as a result of trauma, injury, or medical complications.
This phenomenon is most commonly seen in cases of physical trauma, such as contusions or lacerations, where blood vessels are ruptured due to external force. When blood extravasation occurs, the escaped blood collects in the surrounding tissues, causing localized swelling, bruising (also known as ecchymosis), and discoloration in the affected area.
In medical contexts, blood extravasation can also refer to internal bleeding or hemorrhage that occurs within body cavities, organs, or tissues due to pathological conditions or medical procedures. This can occur in various conditions, ranging from ruptured blood vessels in the brain (cerebral hemorrhage) to localized bleeding after surgery (surgical hemorrhage).
Detection of blood extravasation is often done through clinical examination, imaging techniques such as X-rays or ultrasounds, or laboratory tests that measure hematologic parameters. Treatment depends on the location, extent, and severity of the extravasation, and may involve conservative management, such as rest and ice application, or more invasive interventions, including surgical repair or drainage procedures.
Overall, blood extravasation involves the abnormal leakage of blood from blood vessels into surrounding tissues or spaces, leading to localized swelling, bruising, and discoloration.
The word "extravasation" is derived from the Latin word "extravasare", which means "to force out from the vessel". It is formed by combining the prefix "extra", meaning "outside", and "vasa", meaning "vessel".
The term "blood extravasation" combines "extravasation" with "blood", referring to the escape or leakage of blood from its normal circulatory system into surrounding tissues due to trauma or other causes. The word "blood" comes from Old English "blōd", which has Germanic roots.
Therefore, the etymology of "blood extravasation" highlights the Latin origin of "extravasation" and the Old English origin of "blood".
