Aspiration is a medical procedure used to remove fluid or tissue from the body using a needle or syringe. It is commonly used to drain abscesses, cysts, or other fluid-filled masses, as well as to obtain samples for diagnostic tests.
Aspiration can be performed under local anesthesia or sedation, depending on the location and type of aspiration. The procedure is often guided by ultrasound or other imaging techniques to ensure precise targeting of the fluid or tissue. Aspiration helps relieve symptoms, such as pain or pressure, and allows healthcare providers to analyze the sample for infection, inflammation, or other underlying conditions.
