Renal Artery Stenting for Traumatic Dissection

Renal injuries are frequently seen in the context of trauma, with currently well-established guidelines for classification and management, such as those prescribed by the American Association for the Surgery of Trauma. However, traumatic dissection of the renal arteries specifically is uncommon; clarity regarding optimal management is currently lacking, despite the possible long-term sequelae, including loss of nephron function and renovascular hypertension. While medical management alone had sometimes been suggested, endovascular stenting is potentially a viable minimally invasive intervention that may further reduce the risk of long-term complications. In this report, we present a case of traumatic renal artery dissection first seen on computed tomography in a patient who presented following a high-speed road traffic accident. Percutaneous endovascular stenting of a dissected renal artery was performed, with subsequent restoration of renal perfusion on follow-up imaging, as well as maintenance of normal serum creatinine and blood pressure at longer-term follow-up. We also review the existing literature, which, despite the scarcity, affirms our experience of favourable outcomes post-intervention.
