Extravasated (/ɪkˈstræv.ə.seɪ.tɪd/) is a medical term that refers to the escape of fluid or blood from its vessel into surrounding tissues. The pronunciation of this word can be broken down into individual phonetic sounds. The "e" sounds like the "i" in "sit," followed by the "k" sound. Then, the "a" sounds like the "a" in "cat," while the stress falls on the second syllable. The "-ted" part is pronounced like a standard past-tense ending, rhyming with "led" or "said."
Extravasated is an adjective used to describe a condition where a fluid or substance, typically blood, leaks or escapes from its intended vessel or container and spreads into surrounding tissues or spaces. The term is commonly used in medical and scientific contexts to describe physiological processes or pathological events.
When a blood vessel ruptures or is damaged due to injury or disease, blood can extravasate into nearby tissues, resulting in a localized hemorrhage. This can occur in various parts of the body, such as the skin, organs, or internal cavities. The extravasated blood may cause visible signs like bruising, swelling, or discoloration, depending on its extent and location.
Extravasation can also occur in other situations involving substances other than blood. For example, in the context of chemotherapy administration, extravasation refers to the accidental leakage of cytotoxic drugs into the surrounding tissues, which can cause severe tissue damage and complications.
The term "extravasated" is derived from the Latin word "extravasare," meaning "to stray outside." It highlights the displacement or abnormal escape of a substance from its normal confines. Understanding the concept of extravasation is crucial in medical practice to diagnose and manage conditions associated with abnormal fluid leakage, ensuring appropriate treatment and care.
Forced out of the arteries, veins, &c., as the blood by which the skin is discoloured in bruises.

The word extravasated comes from the Latin word extravasatus, which is the past participle of the verb extravasare. Extravasare consists of two parts: extra, meaning outside, and vasare, derived from vas, meaning vessel. Therefore, extravasare literally means to wander outside the vessel. Over time, extravasare evolved into extravasate in English, and the adjective form is extravasated.
