Endovascular coiling in the treatment of patients with renal artery aneurysms

Endovascular coiling is a percutaneous endovascular technique used in the management of arterial aneurysms with high success rates and minimal associated morbidity. We present a series of three patients with incidental renal artery aneurysms treated successfully with endovascular coiling, despite comorbidities. One patient had an aneurysm associated with a solitary kidney. The decision to use this technique becomes critical when the aneurysm involves a single functioning kidney. Each renal artery aneurysm was successfully coiled by combining vascular and neurointerventional techniques. The results from the present case series also highlight the challenges faced in therapeutic decision-making in complex situations with limited error margins.
