Key result
Image fusion-augmented angiography linked to ~56% higher right adrenal vein cannulation success vs conventional methods.
Why the study?
Image fusion–augmented angiography may improve right adrenal vein cannulation success during adrenal vein sampling, but its effectiveness was not established.
Does image fusion-augmented angiography improve right adrenal vein cannulation success rate in patients undergoing adrenal vein sampling?
Cohort (n=41)
Does image fusion-augmented angiography improve right adrenal vein cannulation success rate in patients undergoing adrenal vein sampling?
Image fusion-augmented angiography significantly improves right adrenal vein cannulation success and reduces radiation exposure during adrenal vein sampling.

May support image fusion to raise right adrenal vein cannulation success and cut radiation; leaves open need for randomized confirmation before routine adoption.
Image fusion–augmented angiography to guide cannulation during adrenal vein sampling (AVS) entails fusion between preprocedural CT images on which ring markers indicate adrenal vein ostia and live digital subtraction angiography fluoroscopic images. In patients who underwent adrenal vein sampling (18 without, 23 with image fusion–augmented angiography), image fusion–augmented angiography increased the success rate of right adrenal vein cannulation (55.6% to 87.0%; p = .04) and reduced fluoroscopy time (23.7 to 16.3 minutes; p = .03) and dose area product (532,195 to 91,403 mGy ∙ cm2; p = .006).

Lee et al. (2021) conducted a cohort in Patients undergoing adrenal vein sampling (n=41). Image fusion-augmented angiography vs. Without image fusion-augmented angiography was evaluated on Success rate of right adrenal vein cannulation (p=.04). Image fusion-augmented angiography increased the success rate of right adrenal vein cannulation compared to conventional methods (87.0% vs 55.6%; p=0.04).
