Our goal was to analyze the indications and limitations of the different percutaneous endovascular approaches reported for the treatment of renal artery aneurysms (RAAs) and to develop a scientific approach for optimum selection of treatment strategy of RAAs through analyzing our experience and reviewing available literature.
This retrospective study was designed to evaluate the treatment and follow-up of 13 consecutive patients who presented with 13 RAAs by using a variety of endovascular interventional techniques. Different combinations of coil embolization, liquid embolization, stenting, and stent-graft exclusion were used in correlation with variable-specific aneurysm criteria.
All patients were successfully treated with no significant short- or long-term complications. Patients were followed for an average period of 43 (range 13–103) months.
Ten different determinants were found to affect our decision making: shape, size, neck, position of aneurysm on artery, branches arising, artery involved, condition of the artery, age, general condition of the patient, and renal function.
