Adrenal Vein Sampling ; Definition, Diagnostic Procedure, Uses

Adrenal vein sampling (AVS) is a diagnostic procedure used to determine if one or both adrenal glands are producing excess hormones, particularly aldosterone. Here's a brief overview: What is AVS? Purpose: To identify the source of excess aldosterone production, which can cause conditions like primary aldosteronism (Conn's syndrome). Procedure: An interventional radiologist inserts a catheter through the groin to access the adrenal veins and collect blood samples. Why is AVS Performed? Diagnose Primary Aldosteronism: To confirm if one or both adrenal glands are overproducing aldosterone. Guide Treatment: Helps determine if surgical removal of an adrenal gland is necessary. Identify Tumors: Can locate small adrenal tumors that might not be visible on imaging studies. Procedure Details Preparation: You may need to stop certain medications and avoid eating or drinking before the procedure. During the Procedure: You'll receive local anesthesia or light sedation. The radiologist will use imaging guidance to place the catheter and collect blood samples from the adrenal veins2. Post-Procedure: You may need to rest for a few hours and arrange for someone to drive you home. Risks and Benefits Risks: Minor bleeding, bruising, or infection at the catheter site. Benefits: Accurate diagnosis and appropriate treatment planning for adrenal gland disorders. #AdrenalVeinSampling
