Selective embolization of a renal artery aneurysm.

The treatment modalities for renal artery aneurysm have changed. The aim in the presented case was to evaluate the endovascular therapy in a 52-year-old woman (with hematuria as the only symptom) with a saccular aneurysm at the first bifurcation of the right main renal artery, which was diagnosed with contrast-enhanced computerized tomography and angiography. We approached the aneurysm with minimally invasive supraselective embolization. There were no postoperative complications, as confirmed with control angiography, during the intervention and after an interval of 4 weeks. In conclusion, selective coil embolization as first-line therapy to treat saccular renal artery aneurysm is feasible. In this case, minimally invasive procedure provided maximum functioning kidney tissue.
