Spontaneous renal artery dissection in a patient with contralateral renal artery stenosis: Treatment with percutaneous endovascular stent placement

We report a 36-year-old man with poorly controlled hypertension, who suffered from acute deterioration and marked elevation of blood pressure. Abdominal bruit was heard in the right epigastric area. Renovascular hypertension was highly suspected. Spontaneous right renal artery dissection superimposing contralateral renal artery stenosis was found by computed tomography, and confirmed by conventional angiography. Percutaneous endovascular intervention was done successfully, with dramatic clinical improvement. Renovascular hypertension must be considered in patients with refractory hypertension. Better control of blood pressure, or even cure of hypertension, can be achieved with percutaneous endovascular intervention both in stenosis and dissection of renal arteries.
