Which vein does the right adrenal vein typically drain into?

The right adrenal vein typically drains directly into the Inferior Vena Cava (IVC). This is a key anatomical feature of the venous drainage system for the right adrenal gland. The IVC collects blood from the lower body and is positioned on the right side of the vertebral column, which aligns anatomically with the right adrenal vein's course.

Understanding this drainage pattern is important in interventional radiology for various procedures, including adrenal vein sampling for hormonal assessment or certain diagnostic interventions. It's also significant in the context of adrenal tumors or involvement with vascular structures, where knowledge of the venous drainage can influence the management strategy and approach to intervention.

The left adrenal vein, in contrast, drains into the left renal vein, which is distinct from the right adrenal's drainage route to the IVC. This anatomical difference is crucial for clinicians to appreciate, as it can impact the approach to imaging or intervention depending on the location of pathology and the vascular anatomy involved.
