11-Deoxycortisol may be superior to cortisol in confirming a successful adrenal vein catheterization without cosyntropin: a pilot study.
AIM: We aimed to compare the performance of nine adrenal steroids in confirming the correct catheter position during adrenal venous sampling (AVS) without cosyntropin in patients with primary hyperaldosteronism.
MATERIALS & METHODS: A successful adrenal vein catheterization without cosyntropin was defined as the ratio of steroids from adrenal to peripheral veins being >3:1. AVS samples from four patients with primary hyperaldosteronism were analyzed.
RESULTS: Compared with the mean ratio of cortisol without cosyntropin, the ratios of 11-deoxycortisol (p = 0.008), dehydroepiandrosterone (p = 0.01) and androstenedione (p = 0.008) were significantly higher. None of the ratios (n = 8) of cortisol from adrenal to peripheral veins exceeded 3:1, while all ratios of 11-deoxycortisol (p < 0.001) were >3.
CONCLUSION: Cosyntropin infusion during AVS may not be necessary if 11-deoxycortisol is used to confirm catheter position.
