In FAST/Trauma ultrasound, the splenorenal recess, or splenorenal space, is a crucial anatomical landmark located between the spleen and the left kidney. This potential space is a key area for detecting free fluid, such as blood, following blunt abdominal trauma. Identifying fluid here is a critical indicator of splenic injury or other intra-abdominal hemorrhage during a Focused Assessment with Sonography for Trauma (FAST) exam.
Sonographers meticulously evaluate the splenorenal recess for anechoic (black) or hypoechoic fluid collections, which signify internal bleeding. Prompt and accurate ultrasound assessment of this region is essential for guiding clinical management and determining the need for further diagnostic interventions in emergency medicine and trauma care.
