Clinical Trial Summary

This study aim to understand whether the length of preoperative supine time would affect the AVS outcome.


Description:

Primary aldosteronism (PA) is the most common form of secondary hypertension, accounting for 5% of hypertensive patients and 17-23% in patients with resistant hypertension. Compared to the primary hypertension, PA is more prone to cause severe organ damage and even early death. Adrenal venous sampling (AVS) is an effective confirmatory test for subtyping unilateral and bilateral adrenal hyperplasia, helping doctors to make an accurate decision between surgery or medication. Supine in bed before AVS is recommended for a desirable result of AVS according to guidelines. However, investigating study about the most optimal preoperative supine time before AVS is lacking. This is a single-center prospective randomized controlled study. 120 patients diagnosed as PA and with willing for further AVS examination will be included. Participants will be randomly allocated to 15-min supine time group or 2-hours supine time group. The primary outcomes are the degrees of clinical and laboratory remission (blood pressure, type and dose of antihypertensive drugs, serum potassium, orthostatic ARR). The secondary outcomes are the technical success rate and adverse event of AVS (selective index≥2 is considered as successful surgery without corticotropin stimulate). Discussion: Primary aldosteronism is an intractable public health problem, and many techniques including AVS have been developed to correctly identify this disease. This study will help to understand whether the length of preoperative supine time would affect the diagnostic efficacy of AVS, and thus help to formulate a more reasonable AVS procedure.

Outcome

Type Measure Description Time frame Safety issue
Primary The rate of complete biochemical remission Compare the rate of complete biochemical remission between two groups. 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 The rate of complete clinical remission Compare the rate of complete clinical remission between two groups. The proportion of complete clinical remission according to PASO consensus criteria. Clinical outcomes were determined by the blood pressure response to treatment and the number and dosage of antihypertensive medications. At 6 months of follow-up
Secondary Successful catheterization rate Intraoperative bilateral SI value was used to judge whether the blood collection cannula was successful. In the surgery absence of osyntropin, SI=2 was used as the standard for successful blood collection and LI=2 was used for judging the dominant side aldosterone secretion. At baseline
Secondary Adverse events Record the occurrence of adverse events, including adrenal venous hemorrhage and related adrenal insufficiency, hypertensive urgencies, anaphylactic shock, venous thrombosis, pulmonary embolism, ect. At 3 months of follow-up
