Is the suppression index in adrenal venous sampling of the left adrenal vein a potentially sufficient criterion for adrenalectomy in primary aldosteronism patients with a right adrenal gland adenoma?

Key Points

• The suppression index may serve as a sufficient criterion for adrenalectomy in select patients with primary aldosteronism.
• Technical challenges in catheterization of the right adrenal vein can lead to incomplete sampling results during adrenal venous sampling.
• Identifying reliable criteria for adrenalectomy can improve surgical outcomes for patients diagnosed with right adrenal gland adenoma.
• Further investigation is needed to validate the role of suppression index in determining the need for adrenalectomy.
