Introduction
True renal artery aneurysms (RAAs) are uncommon, and their actual prevalence is unknown. The indications for treating RAAs include symptomatic aneurysms, larger than 20 mm or enlarging aneurysms during follow-up, aneurysms in patients in childbearing age or in pregnant women, ruptured aneurysms, false aneurysms, and aneurysms associated with arteriovenous fistulas or dissection.
Aim
This retrospective study describes our experience with the endovascular treatment of RAAs with special consideration given to the indications, technical considerations, and complications.
Patients and methods
Endovascular therapy techniques were offered to selected patients with RAAs presented at Vascular Surgery Department, Cairo University Hospitals, between December 2017 and December 2018.
Results
During the study period, five patients diagnosed with RAAs were selected for endovascular therapy. Their age range was 35–57 years (mean, 46 years). From the five patients (four males and one female), three patients with RAAs (two true and one false aneurysm) underwent coil embolization, whereas two patients (one female and one male) with true aneurysms underwent stent graft therapy. The average length of postoperative hospital stay was 4.0 days. Technical success was achieved in all patients. Perioperative morbidity was not observed in any patients, and there were no postoperative mortalities. No evidence of growth of the aneurysm sac or endoleak was observed during follow-up in any patient.
Conclusion
Current data support the high safety of endovascular treatment of RAAs with all of its available techniques.
