Summary
Superselective adrenal arterial embolization (SAAE) effectively treats aldosteronomas, with an 82% success rate and no severe complications. This minimally invasive procedure offers long-term benefits for hypertension management.
Area of Science:
- Endocrinology
- Interventional Radiology
Background:
- Aldosteronomas are a common cause of primary aldosteronism and hypertension.
- Surgical adrenalectomy is a traditional treatment, but minimally invasive options are sought.
Purpose of the Study:
- To evaluate the effectiveness and long-term outcomes of superselective adrenal arterial embolization (SAAE) for aldosteronomas.
Main Methods:
- Thirty-three patients with unilateral aldosteronomas underwent SAAE using high-concentration ethanol (HCE).
- Microcatheter-guided selective infusion of HCE into feeding arteries was performed.
- Hormone, electrolyte, and blood pressure levels were monitored post-procedure.
Main Results:
- SAAE achieved an 82% success rate in 33 patients.
- No severe complications were observed.
- Blood pressure significantly decreased in younger patients (<45 years) and showed a correlation with age.
Conclusions:
- SAAE with HCE is a safe and effective therapeutic option for aldosteronoma.
- The procedure demonstrates sustained efficacy and potential for long-term hypertension management.
