Dynamic renal artery stenosis: An incidental angiographic diagnosis or is there more to it than meets the eye?

Puneeth Shridhar*, Gustav Eles, David Lasorda, Young Jae Chun

Renal artery stenosis is a major cause of secondary hypertension. Bilateral non-atherosclerotic non-dysplastic renal artery stenosis can be seen following compression of the renal arteries by diaphragmatic crura/median arcuate ligament or external masses or fibrous bands. Never before, dynamic bilateral proximal stenosis, a new entity has been reported. The treatment is unknown. The learning point is that the patients undergoing angiographic screening for renovascular hypertension should undergo ‘breath in breath out’ test in order to visualize renal artery motion.
