Flash pulmonary edema is characterized by a sudden episode of dyspnea resulting from acute pulmonary venous congestion, which resolves rapidly. We report a case of renal artery stenosis presenting as flash pulmonary edema in a patient with solitary kidney treated by angioplasty with stent implantation. A 75-year-old man with solitary kidney visited the emergency room with acute shortness of breath. His blood pressure had risen to 206/90 mmHg and a chest radiograph revealed pulmonary edema. Echocardiography and coronary arteriography showed no clear abnormalities, but abdominal computed tomography revealed severe focal stenosis in the left proximal renal artery. A captopril renal scan found that the time to peak and half-time of radioactivity were delayed in the left kidney. Percutaneous transluminal angioplasty was performed, followed by stent implantation. After this procedure, the stenotic segment was completely dilated and blood pressure returned to the normal range.
