Endovascular Treatment of Spontaneous Renal Artery Dissection After Failure of Medical Management.

Spontaneous renal artery dissection (SRAD) is a rare disease with approximately 200 cases reported in the literature. The severity of renal compromise, the anatomic location of the dissection, and the presence of uncontrollable hypertension are used to guide the initial management of SRAD. However, there are no reported guidelines for managing the progression of SRAD after acute failure of medical management. In this case, a 40-year-old man with a recently diagnosed SRAD was managed appropriately with therapeutic anticoagulation, yet presented with progression of his dissection and a new acute renal infarct. A covered endovascular stent was used to successfully control dissection progression and prevent further renal compromise. [ABSTRACT FROM AUTHOR]
