Renal Artery Stenting Recovered Renal Function After Spontaneous Renal Artery Dissection

Spontaneous renal artery dissection (SRAD) is a rare entity and the management of this disease has not been established. A 54-year-old man presented with severe flank pain, and contrast-enhanced computed tomography images suggested SRAD in his left renal artery. After two weeks of conservative treatment, stents were placed in the renal artery. The pre- and post-procedural renal function was independently assessed by renography. After stenting, his left renal function recovered from the renal failure pattern. Renal artery stenting in an acute phase of SRAD may salvage the renal function, even if it appears to be non-functioning.
