Brief summary

The subjects of this study were patients with essential refractory hypertension. The purpose of this study is to evaluate the safety and efficacy of superselective adrenal arterial embolization (SAAE) in patients with primary refractory hypertension and to explore the possibility of SAAE in patients with primary refractory hypertension.After the subject completes the SAAE, an 8-week follow-up will be conducted to assess the safety and effectiveness of the SAAE.

Detailed description

The subjects of this study were patients with essential refractory hypertension. The study design was a single-center, open-label, self-controlled, single-arm, prospective study. The purpose of this study is to evaluate the safety and efficacy of superselective adrenal arterial embolization (SAAE) in patients with primary refractory hypertension and to explore the possibility of SAAE in patients with primary refractory hypertension.After the subject completes the SAAE, an 8-week follow-up will be conducted to assess the safety and effectiveness of the SAAE.

Interventions

Superselective adrenal arterial embolization is an operation to inject embolic agent into adrenal artery through catheter to embolize part of adrenal gland, so as to reduce the secretion of adrenal hormone and reduce blood pressure.
