What is the aortocaval space in the mid to lower abdomen?

The aortocaval space is the anatomical region in the mid to lower abdomen located between the aorta and the inferior vena cava. It contains important structures, including lymph nodes, blood vessels, and connective tissue. This space is clinically significant as it can be involved in various pathologies, including tumors or hematomas, which may affect the aorta or the inferior vena cava. Proper understanding of this area is crucial during surgical procedures and imaging assessments in the abdominal cavity.
