Nephrotic syndrome and recurrent pulmonary oedema in bilateral atherosclerotic renal artery stenosis: resolution following renal angioplasty and stenting.

Hypertension and episodic pulmonary oedema are known complications of bilateral renovascular disease. However, significant proteinuria has not been reported in this setting. We describe a patient who presented with recurrent pulmonary oedema and nephrotic syndrome, and was found to have bilateral renal artery stenosis. Percutaneous angioplasty and stenting led to a complete resolution of both, confirming a causal relationship. This is perhaps the first report documenting the rare combination of nephrotic syndrome and flash pulmonary oedema due to bilateral renal artery stenosis.
