Purpose: To describe a novel technique of transvenous radiofrequency catheter ablation of an aldosterone-producing adenoma (APA) of the left adrenal gland using the GOS System (Japan Lifeline, Tokyo, Japan). Using the GOS system, a flexible radiofrequency tip catheter can be inserted into the adrenal central and tributary veins, the drainers for functional tumors.
Materials And Methods: An APA at the left adrenal gland, which was diagnosed by segmental adrenal venous sampling following administration of 0.
Transvenous Radiofrequency Ablation of Adrenal Gland: Experimental Study.

Article Synopsis
- - The study focused on testing a flexible radiofrequency-tip catheter designed for adrenal gland ablation, evaluating it both in a gel model and in a live animal (pig) setting.
- - Results showed effective ablation diameters of 10 mm in the pigs after applying 7000 J of energy, with no complications during the procedure and no thermal damage to surrounding organs.
- - The findings suggest that this transvenous adrenal ablation method could be a promising treatment option for conditions like primary aldosteronism.

Purpose: To evaluate the coagulative performance of a 21-gauge (G) internally cooled radiofrequency (RF) electrode using ex vivo and in vivo rat liver.
Materials And Methods: We developed a prototype of 21-G internally cooled monopolar RF electrode with 5.0 mm active tip length.
