Long-term results of blunt traumatic renal artery dissection treated by endovascular stenting.
A 20-year-old man was admitted to the emergency department after falling 15 m onto the roof of a car and landing on his back. Imaging by computed tomography (CT) showed delayed perfusion of the right kidney and no excretion of contrast from that kidney on delayed images. Angiography confirmed a localized intimal dissection in the right main renal artery. We inserted a balloon-expandable stent using a transfemoral approach to successfully repair the dissection. At 4 year follow-up, Doppler ultrasound of the right renal artery and renal scintigraphy demonstrated preserved function of the right kidney. Our findings support endovascular stenting as a safe, effective and efficient treatment for blunt renal artery injury.
