| description | Determines whether to recommend adrenalectomy or mineralocorticoid receptor antagonists for primary aldosteronism based on PA subtype and patient/surgical factors. Triggered after subtype confirmation when clinicians ask “Should this patient have surgery or medical treatment?” or discuss treatment options with the patient. |
Select between adrenalectomy and medical therapy for PA management
STEP 1 — Gather Information
Collect AVS results (or alternative subtype diagnosis) to determine unilateral vs bilateral PA, patient age, serum potassium, PAC, adrenal CT findings, patient preference for surgery, and surgical contraindications.
Action: Proceed to subtype classification.
STEP 2 — Rule In / Rule Out
Is PA unilateral? If yes, proceed to evaluate surgical suitability; if no (bilateral), recommend medical therapy with MRAs.
Action: For bilateral PA, start MRA therapy; for unilateral PA, move to candidacy assessment.
STEP 3 — Classify or Stratify
Among unilateral PA patients, assess surgical candidacy: age <35 years, spontaneous hypokalemia (<3.5 mEq/L), PAC >300 pg/mL, unilateral adrenal tumor on CT, patient desire for surgery, and absence of major surgical comorbidities.
Action: Classify as surgical candidate if criteria met; otherwise classify as non‑surgical candidate.
STEP 4 — Decide
If surgical candidate, recommend adrenalectomy; if non‑surgical candidate (unilateral PA not meeting criteria) or bilateral PA, recommend medical therapy with MRAs.
Action: Initiate adrenalectomy or MRA therapy accordingly.
Clinical Guardrails / Mimics / Pitfalls
Do not recommend adrenalectomy without confirming unilateral subtype; avoid bypassing AVS in patients >35 years or lacking typical features (hypokalemia, high PAC, unilateral tumor); respect patient refusal of surgery even when criteria are met; do not initiate MRAs in bilateral PA without subtype confirmation; monitor for postoperative hyperkalemia and adrenal insufficiency if cortisol co‑secretion is suspected; avoid MRAs in patients with severe renal impairment or hyperkalemia risk without appropriate precautions.
Concrete Clinical Example
A 32‑year‑old woman with spontaneous hypokalemia (K⁺ 3.2 mEq/L), PAC 350 pg/mL, ARR 650, and a 1.8 cm left adrenal adenoma on CT undergoes AVS showing lateralization index > 4 with ACTH. She meets all surgical criteria and desires curative treatment. Laparoscopic left adrenalectomy is performed, normalizing BP and K⁺ postoperatively.
