Summary
Computed tomography (CT)-guided cryoablation safely and effectively treated functional adrenal aldosteronoma in 11 patients. This minimally invasive procedure resulted in complete tumor ablation and significant improvements in aldosterone levels and blood pressure.
Area of Science:
- Endocrinology
- Interventional Radiology
- Oncology
Background:
- Functional adrenal aldosteronoma is a condition characterized by excessive aldosterone production.
- Minimally invasive treatments are increasingly sought for adrenal tumors.
Purpose of the Study:
- To evaluate the safety and clinical effectiveness of computed tomography (CT)-guided cryoablation for functional adrenal aldosteronoma.
Main Methods:
- Eleven patients with functional adrenal aldosteronoma underwent CT-guided cryoablation between June 2012 and December 2018.
- Data collected included complete ablation rate, clinical success, complications, and long-term outcomes.
Main Results:
- Complete ablation was achieved in all 11 patients after a single session with no procedure-related complications.
- Significant reductions in aldosterone levels (p < .001), systolic blood pressure (p < .001), and diastolic blood pressure (p = .005) were observed.
- Mean renin and potassium levels improved significantly (p < .001), with no recurrence of tumor or symptoms during follow-up.
Conclusions:
- CT-guided cryoablation is a safe and effective treatment modality for functional adrenal aldosteronoma.
- The procedure demonstrates high efficacy with excellent patient outcomes and no reported complications.
