Feasibility and Safety Clinical Study of a Novel Technique for Simultaneous Bilateral Adrenal Vein Sampling via Right Elbow Venous Access: A Prospective Clinical Study
Authors' conclusion
The implementation of simultaneous bilateral AVS through the right cubital vein using specialized catheters significantly simplifies the procedure, increases surgical success, and reduces patient trauma. The high success rate, coupled with a low complication incidence, underscores the technique's safety, feasibility, and substantial clinical implications, suggesting broad applicability for improved PA management.
