AB052. SOH23ABS_030. Treatment planning approaches for the management of functioning adrenal nodules

Background: Primary aldosteronism is the most common cause of secondary hypertension worldwide. Thermal ablation, via a minimally invasive interventional radiological approach or laparoscopic surgical approach, offers an option for the targeted destruction of aldosterone producing adrenal lesions which have been located in one or both adrenal glands. Accurate treatment planning is needed to ensure optimal ablation with minimal associated collateral damage to normally functioning adrenal cortex. The objective of this study was to evaluate the use of simulated treatment planning system to inform the dose and duration of microwave ablation (MWA) thermal ablation in patients with primary aldosteronism (PA).
