🧵#10/10 Final Takeaway.In AVS, don’t trust a single number. Even in a well-performed session, lateralization can shift. Multiple samples = more reliable subtyping.Should protocols require triplicate sampling?!.#RadInTraining.

🧵#9/10 Strengths & Limitations.Strengths:. - 400+ patients. - Single experienced operator. - Rigorous protocol.Limitations:.- Retrospective.- No genetic correlation.- Single center.Still, it’s the largest intraprotocol AVS study to date.

🧵8/10 Clinical Implications.AVS results may misguide treatment if only 1 sample set is used. Takeaways:.- Always collect multiple samples.- Avoid decisions based on a single LI.- Cosyntropin helps, but doesn’t eliminate variability.

🧵7/10 Why Does This Happen?.Possible causes of AVS variability include:.- Hormonal surges during catheter placement.- Fluctuating ACTH responses.- Cortisol/aldosterone assay variation.- Non-dominant gland swings.- Right AV contamination.

🧵6/10 How Bad Was It?.Within the same triplicate set, LI varied significantly:.- Baseline LI variation: up to 153.- Stimulated LI variation: up to 327.Subtyping (unilateral vs bilateral) flipped depending on which sample was used.

🧵5/10 The Shock Factor.1 in 3 patients had different subtyping results within the same session:.- 22.1%: baseline inconsistencies.- 13.2%: post-cosyntropin inconsistencies.- 3.2%: inconsistencies in both sets.That's clinically significant.

🧵4/10 AVS Protocol.Each patient underwent triplicate AVS sampling:.- 3 baseline samples (5 mins apart).- Cosyntropin (0.125 mg bolus + infusion).- 3 post-stimulation samples (5–30 min window).LI = Aldosterone/Cortisol (dominant ÷ nondominant adrenal).

🧵3/10 Why This Study?.AVS is the gold standard for lateralization. But what if results fluctuate during the same procedure?.This study asked:.How often does the lateralization index (LI) vary during triplicate AVS sampling (baseline + post-cosyntropin)?.

🧵2/10 Clinical Context:.Primary aldosteronism (PA) is a common, curable cause of secondary hypertension. Subtyping PA determines treatment:.- Surgery → unilateral.- Medical → bilateral.Imaging often fails, so we rely on AVS.

🧵1/10 What if the same adrenal vein sampling (AVS) session gave different answers minutes apart?. A new @radiology_rsna study of 402 pts found 32% had intraprotocol inconsistencies in lateralization. Here's why it matters👇.🔗 #RadInTraining @VChernyakMD
