Perisplenic fluid

Perisplenic fluid, in the context of FAST (Focused Assessment with Sonography for Trauma) and trauma, refers to the accumulation of free fluid, typically blood, around the spleen. This critical finding on an ultrasound exam suggests potential splenic injury or other internal hemorrhage, which can result from blunt abdominal trauma. Rapid identification of perisplenic fluid is crucial for guiding immediate clinical management and surgical intervention in unstable trauma patients, as it indicates a significant source of bleeding.

Ultrasound plays a pivotal role in quickly detecting perisplenic fluid, often appearing anechoic or hypoechoic in the splenorenal recess. Its presence highlights the need for urgent assessment of the spleen and surrounding structures. Mastering the recognition of perisplenic fluid in a FAST exam is essential for emergency physicians and sonographers to ensure timely and effective patient care in trauma situations.
