Blood screening (aldosterone-to-renin ratio, ARR) was performed at the First Hospital of Fujian Medical University from December 2019 to December 2021, followed by a confirmatory test (dynamic tests to suppress aldosterone production by salt loading, volume expansion, or inhibition of angiotensin-converting enzyme) from December 2019 to December 2021 in the First Affiliated Hospital of Fujian Medical University. A total of 200 patients were diagnosed with PA according to the criteria of an Endocrine Society Clinical Practice Guideline [All patients underwent computed tomography (CT) and AVS and were randomized by a coin flip into two groups, including a single-path group and a multipath group. The single-path group used the cubital vein asynchronous AVS and the multipath group used synchronized AVS via the cubital vein and femoral vein.This study was approved by the Ethics Committee of the First Affiliated Hospital of Fujian Medical University.
