Update in adrenal venous sampling for primary aldosteronism.

Area of Science:

• Endocrinology
• Surgical Innovation
• Diagnostic Procedures

Background:

• Current guidelines recommend adrenal venous sampling (AVS) for hyperaldosteronism, but it is underused.
• Underutilization of AVS denies curative adrenalectomy to many primary aldosteronism patients.
• Perceptions of AVS as technically challenging, invasive, and difficult to interpret hinder its adoption.

Purpose of the Study:

• To challenge the view that AVS is technically challenging, invasive, and risky.
• To address the underutilization of AVS in clinical practice for primary aldosteronism.
• To provide guidance on the proper performance and interpretation of AVS.

Main Methods:

• Review of several studies, including the international AVIS-1 Study.
• Examination of a randomized clinical trial comparing AVS with computed tomography (CT) strategies.
• Analysis of data to inform best practices for AVS.

Main Results:

• Evidence suggests AVS is less challenging and risky than perceived.
• Studies provide insights into optimizing AVS performance and interpretation.
• Specific recommendations can be derived to mitigate risks like adrenal vein rupture.

Conclusions:

• Challenging negative perceptions of AVS is crucial for increased utilization.
• Proper techniques and interpretation guidelines can enhance AVS safety and efficacy.
• Improved AVS use can lead to more patients receiving timely, curative adrenalectomy for primary aldosteronism.
