A Novel Method: Super-selective Adrenal Venous Sampling
Primary aldosteronism (PA) and subclinical Cushing's syndrome (SCS) are conditions in which the adrenal glands autonomously produce excessive amounts of aldosterone and cortisol, respectively. The conventional adrenal venous sampling (cAVS) method collects blood samples from both adrenal central veins and is useful for identifying the laterality of excess hormone production in a unilateral lesi...
متن کاملAdrenal venous sampling in a patient with adrenal Cushing syndrome
The primary bilateral macronodular adrenal hyperplasia or the independent adrenocorticotropic hormone bilateral nodular adrenal hyperplasia is a rare cause hypercortisolism, its diagnosis is challenging and there is no clear way to decide the best therapeutic approach. Adrenal venous sampling is commonly used to distinguish the source of hormonal production in patients with primary hyperaldoste...
متن کاملAdrenal Venous Sampling in Primary Hyperaldosteronism
Adrenal venous sampling (AVS) is used to distinguish unilateral from bilateral aldosterone hypersecretion as a cause of primary hyperaldosteronism (PHA). This distinction is critical because unilateral disease is treated, and often cured, by adrenalectomy, whereas bilateral hypersecretion should be managed medically. In this article, we review the epidemiology and etiologies of PHA, present scr...
متن کاملLocation of extra-adrenal catecholamine secreting tumours by selective venous sampling and nuclear magnetic resonance scanning.
Iodinated meta-iodobenzylguanidine (MIBG) scanning is a safe non-invasive method for locating extra-adrenal paragangliomas. However, a positive result is dependent on the presence of an uptake mechanism in the tumour. We report two cases of MIBG negative intracranial catecholamine secreting tumours successfully located by selective venous sampling and nuclear magnetic resonance scanning.
متن کاملAdrenal Venous Sampling Is Useful for a Definitive Diagnosis in Cushing's Syndrome with Bilateral Adrenal Tumors.
We report three cases of Cushing's syndrome (CS) with bilateral adrenal tumors. When bilateral adrenal tumors are encountered, a differential diagnosis is difficult to make, especially in the case of functioning bilateral adrenocortical adenoma. Adrenal scintigraphy has become a standard technique to determine the laterality of excessive hormone secretion; however, this examination results in b...
