Features and Uniqueness
  • Primary aldosteronism is a leading cause of secondary hypertension accounting for approximately 10 % of hypertensive patients; 4 million patients potentially exist in Japan. We aim to optimize the method of ablating aldosterone producing adenoma using newly developed bipolar radiofrequency ablation system with 300-400kHz high-frequency current and electric power of 40W (Celon Prosurge Applicator), and establish a less invasive interventional radiological treatment of primary aldosteronism.
Practical Application

Collaboration with medical equipment manufacture and universities are expected to develop new devices enabling ablation of aldosterone producing adenoma. Flexible guide-wire-type ablation system and rapid aldosterone assay system should be co-developed to tread aldosterone producing microadenoma which is difficult to detect due to its small diameter of less than 5mm.
