Renovascular hypertension secondary to spontaneous renal artery dissection and treatment with stenting

Abstract

Renovascular disease is the cause of less than 1% of patients with hypertension; within this group aneurysm and dissection in renal artery are even rarer causes. It may be not only iatrogenic or traumatic, but may also develop spontaneously from fibromuscular disease or atherosclerotic lesions. We present a 26-year-old male patient with recently developed and progressive hypertension in whom renal angiography showed aneurysmal dilatation and dissection of the right renal artery. With the implantation of two stents in the true lumen, normal renal blood flow and thrombosis of the aneurysmal sac was established. As a result, stent implantation to renal artery dissection is effective, reliable and easy and can be an alternative to surgical treatment.
