Primary Hyperaldosteronism: Effect of Adrenal Vein Sampling on Surgical Outcome

Nwariaku, Fiemu E.·2006·Archives of Surgery

Abstract

HYPOTHESIS: Adrenal vein sampling is superior to computed tomography for subtype differentiation of primary hyperaldosteronism. DESIGN: Retrospective review. SETTING: University medical center. PATIENTS: Forty-eight patients (32 men and 16 women) with biochemically confirmed primary hyperaldosteronism. MAIN OUTCOME MEASURES: We compared demographic factors, results of biochemical and imaging studies (computed tomography and adrenal vein sampling), therapy, and patient outcomes. RESULTS: Mean +/- SEM adrenal nodule size was 1.54 +/- 0.2 cm. Adrenal vein sampling was performed in 41 (85%) of 48 patients, and it was successful in 39 (95%) of those 41 patients. Concordance between computed tomography and adrenal vein sampling was observed in 22 (54%) of the 41 patients. Thirty-two patients underwent successful laparoscopic adrenalectomy. There was 1 complication and no deaths. All 32 patients were cured of hypokalemia. CONCLUSION: Adrenal vein sampling is superior to image-based techniques for subtype differentiation of primary hyperaldosteronism.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
