Detailed Description

This is a randomized study involving patients with primary aldosteronism (PA) patients with adrenal nodule (≥1cm) who completed AVS or 68Ga-Pentixafor PET/CT.We will enroll 320 PA patients with adrenal nodule (≥1cm) .All paticipants will be randomized into 68Ga-Pentixafor PET/CT group(Intervention group) and AVS group(Control group) to compare the long-term outcomes of patients with PA.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: 68Ga-Pentixafor PET/CT group; Patients divided into 68Ga-Pentixafor PET/CT group need to undergo 68Ga-Pentixafor PET/CT examination and guide subsequent treatment based on the results	Diagnostic test: 68Ga-Pentixafor PET/CT; The patients had a normal diet with no special preparation before 68Ga-Pentixafor PET/CT imaging. The dosage of intravenously injected 68Ga-Pentixafor was calculated based on the patient's weight (1.85 MBq [0.05mCi]/kg). Local PET/CT scanning of the upper abdomen was performed on a hybrid PET/CT scanner at 10 minutes after the injection of the intravenous tracer, respectively.
No Intervention: AVS group; Patients divided into AVS group need to undergo AVS to guide subsequent treatment based on the results

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The proportion of complete biochemical remission	Blood was drawn to measure aldosterone, renin and potassium.According to PASO criteria, outcomes of adrenalectomy for unilateral primary aldosteronism were classified into complete, partial, and absent success, for both clinical and biochemical outcomes.The proportion of complete biochemical remission according to PASO consensus criteria.	At 6 months of follow-up.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Daily defined doses (DDD) of antihypertensive agents	Prescribed daily dose (DDD) of antihypertensive drugs (including MRA) in each group after 6-12 months of follow-up.	At 6-12 months of follow-up.
The proportion of complete clinical remission	Blood was drawn to measure aldosterone, renin and potassium.According to PASO criteria, outcomes of adrenalectomy for unilateral primary aldosteronism were classified into complete, partial, and absent success, for both clinical and biochemical outcomes.The proportion of complete biochemical remission according to PASO consensus criteria.	At 6 months of follow-up.
In surgical population, the proportion of complete biochemical remission	Blood was drawn to measure aldosterone, renin and potassium.According to PASO criteria, outcomes of adrenalectomy for unilateral primary aldosteronism were classified into complete, partial, and absent success, for both clinical and biochemical outcomes.The proportion of complete biochemical remission according to PASO consensus criteria.	At 6 months of follow-up.
In surgical population, the proportion of complete clinical remission	Blood was drawn to measure aldosterone, renin and potassium.According to PASO criteria, outcomes of adrenalectomy for unilateral primary aldosteronism were classified into complete, partial, and absent success, for both clinical and biochemical outcomes.The proportion of complete biochemical remission according to PASO consensus criteria.	At 6 months of follow-up.
Total cost of diagnosis and treatment	After patients are determined to be enrolled, treatment costs incurred for the diagnostic process will be calculated for each subject. This includes CT,AVS or PET/CT, surgery, medications, etc.	At baseline and 6 months of follow-up.
Health Related Quality of Life	The quality of life in our patients may be influenced in different ways.AVS is an invasive test, PET/CT does not require any preparation of the patient before the test. Questionnaires of QOL-BREF will be conducted by patients before treatment and at 6-12 months follow-up in each group.This will allow for a detailed analysis of the impact of the two strategies on the quality of life of the patients.	At baseline and 6 months of follow-up.
Comparison of adverse events	The occurrence of adverse events was recorded, including PET/CT contrast agent allergy, adrenal vein hemorrhage and related adrenal insufficiency, hypertensive emergency, anaphylactic shock, venous thrombosis, pulmonary embolism, etc.	At baseline and 6 month of follow-up.
