Isolated spontaneous renal artery dissection: diagnosis and endovascular management.

Spontaneous, isolated focal renal artery dissection is an extremely rare cause of renovascular hypertension. Imaging technology for the renal arteries has evolved recently with the development of multidetector computed tomography angiography (CTA), and intravascular ultrasound. We describe a 52-year-old man with spontaneous renal artery dissection complicated by renovascular hypertension, successfully diagnosed initially with CTA, then evaluated by intravascular ultrasound, and finally, treated successfully with stenting.
