The Safety and Feasibility of Simultaneous Bilateral Adrenal Vein Sampling via Basilic Vein Approach:the First Report
Objectives:To evaluate the safety and feasibility of simultaneous bilateral adrenal vein sampling(AVS)via the basilic vein approach.Methods:21 consecutive patients with primary aldosteronism(PA)who underwent simultaneous bilateral AVS via the basilic vein in Fuwai Hospital between July 2023 and November 2023 were enrolled in this study.The puncture site,catheter used in AVS,operation time,fluoroscopy time,contrast agent dosages,success rate of bilateral sampling,adverse events,and complications were recorded and analyzed.Successful sampling was determined by a selectivity index(cortisol in the adrenal vein/cortisol in inferior vena cava)greater than or equal to 2.Results:The average age of 21 patients was(49.3±7.7)years,with 13 male patients.The first 5F sheath was successfully inserted into the right basilic vein in all patients,the second 5F sheath insertion failed in two patients and switched to the ipsilateral cephalic vein approach.The 5F MPA1 catheter was inserted into the right adrenal vein and the 5F TIG catheter into the left adrenal vein in all patients.Operation time was 17.50(12.00,22.00)min,fluoroscopy time was 5.90(4.75,10.55)min,and contrast agent dosage was 25.00(25.00,35.00)ml.Bilateral AVS was successful in all patients.Two patients experienced adverse events,one case was catheter entanglement,which resulted in 5F TIG catheter slipped from adrenal vein,and another case was vascular spasm.No complications were recorded.Conclusions:Simultaneous bilateral AVS via basilic vein approach is safe and feasible in most PA patients,further researches with larger patient cohort are needed to validate the results from this study.
