متن کاملA Case of Adrenal Vein Sampling in Primary Aldosteronism With Homolateral Suppression
Context Adrenal venous sampling (AVS) is regarded as the gold standard for diagnosis of primary aldosteronism (PA) subtypes, although some authors have questioned its diagnostic accuracy and highlighted the lack of standardized procedure protocols and interpretation criteria for AVS. In particular, the usefulness of cosyntropin stimulation and benefit of superselective adrenal vein catheterizat...
متن کاملUse of NP-59 (131I-iodocholesterol) Scan as a Potential Alternative to Adrenal Venous Sampling in the Investigation of Primary Aldosteronism: a 5-Year Retrospective Study
Objectives: To evaluate the usefulness of NP-59 (131I-iodocholesterol) scan as a non-invasive alternative to adrenal venous sampling in the diagnosis of Conn’s syndrome and lateralisation of aldosterone production. Methods: The electronic patient records of 39 consecutive patients who were referred for NP-59 scan in our centre between 1 January 2007 and 31 December 2012 were reviewed. The resul...
