Changes in Adrenal Hormones During Adrenal Radiofrequency Ablation

Changes in Adrenal Hormones During Adrenal Radiofrequency Ablation

The purpose of this study is to evaluate changes in adrenal hormones during adrenal radiofrequency (RF) ablation.

Adrenal radiofrequency (RF) ablation has been increasingly used for the treatment of unresectable adrenal tumors. But one of the major complication is a increase in blood pressure. Hormonal release during RF ablation is considered the cause of hypertension. But there has been no evidence that adrenal hormones affects changes in blood pressure. In this prospective study, we evaluate the changes in adrenal hormones during RF ablation and clarify the cause of hypertensive crisis.

Inclusion Criteria:

• Unresectable adrenal tumor which will be treated by radiofrequency (RF)ablation
• Blood pressure is 140mmHg or less before RF ablation
• Age of 20-years or more
• Performance status of 0 or 1
• Agreement from the patient

Exclusion Criteria:

• Platelet count of 50,000/mm^3 or International normalized ratio (INR)>1.5
