Q: Pickering Syndrome is described as a combination of “flash” pulmonary edema and? (select one)
A) unilateral renal artery stenosis B) bilateral renal artery stenosis
Pickering was the first to describe the association between acute (flash) pulmonary edema and renal artery stenosis. He reported that acute pulmonary edema in renal artery stenosis predicts more of bilateral pathology instead of unilateral. Treatment is renal artery stents placement.
