An Ancillary Method for Adrenal Venous Sampling in Cases in Which Right Adrenal Vein Sampling Is Difficult [PDF]

Diagnostics, 2023
Catheterization of the right adrenal vein (rt.AdV) to obtain blood samples can often be difficult. The aim of the present study was to investigate whether blood sampling from the inferior vena cava (IVC) at its juncture with the rt.AdV can be an ...

High aldosterone levels in the renal capsular vein from the left aldosterone-producing adenoma on adrenal venous sampling [PDF]

Endocrinology, Diabetes & Metabolism Case Reports, 2023
A 42-year-old female patient was referred to our hospital with hypertension and hypokalemia and was diagnosed with primary aldosteronism. Dynamic contrast-enhanced computed tomography images revealed a 13-mm nodule on the lateral segment of the left ...

Plasma metanephrine for assessing the selectivity of adrenal venous sampling [PDF]

Endocrine Abstracts, 2013
Adrenal vein sampling is used to establish the origins of excess production of adrenal hormones in primary aldosteronism. Correct catheter positioning is confirmed using adrenal vein measurements of cortisol, but this parameter is not always reliable. Plasma metanephrine represents an alternative parameter.

Success Rate of Adrenal Venous Sampling and the Location of Right Adrenal Vein Orifice: A Retrospective Study [PDF]

The Journal of Clinical Hypertension
Adrenal venous sampling (AVS) is the gold standard for identifying aldosterone‐producing adenoma and bilateral adrenal hyperplasia. This study reports the success rate of AVS and the distribution characteristics of the right adrenal vein orifice (RAVO ...

The value of adrenal venous sampling in unveiling the conundrum of double unilateral adrenal adenomas in a case of primary hyperaldosteronism [PDF]

SAGE Open Medical Case Reports
Primary hyperaldosteronism (PHA) is a cause of secondary hypertension, often due to adrenal adenoma. The diagnosis and management of multiple unilateral adrenal adenomas in PHA represent a unique challenge.

Primary Aldosteronism Subtype Diagnosis: Adrenal Venous Sampling vs. CXCR4 PET CT [PDF]

Endocrinology, Diabetes & Metabolism
Purpose To explore the clinical value of adrenal venous sampling (AVS) and CXCR4‐directed 68Ga‐pentixafor PET/CT in the subtype diagnosis of primary aldosteronism (PA), with postsurgical blood pressure control and biochemical cure as primary endpoints ...

Utility of right adrenal signature veins in venous sampling for primary aldosteronism

Annals of Medicine, 2023
Background This study aimed to identify the appropriate signature veins for the right adrenal gland using a 3D model fused with adrenal venography images and to verify their accuracy through the selectivity index (SI) >2.Methods We analyzed the right ...

Adrenal venous sampling in patients with ACTH-independent hypercortisolism [PDF]

Endocrine, 2019
To study the usefulness of adrenal venous sampling (AVS) in distinguishing unilateral from bilateral cortisol production in patients with ACTH-independent hypercortisolism and bilateral adrenal lesions, or morphologically normal adrenal glands.A retrospective analysis of ten consecutive patients with ACTH-independent hypercortisolism who underwent AVS ...
