Endovascular Treatment of Visceral and Iliac Artery Aneurysms and Pseudoaneurysms: Management and Outcome Analysis in A Tertiary Referral Center Over one Decade

Abstract Purpose: To determine the radiological and clinical outcomes of patients with aneurysms and pseudoaneurysms of visceral and iliac arteries submitted to endovascular treatment. Patients and Methods: We evaluated the electronic medical records of patients with aneurysms submitted to endovascular radiological procedure. These cases were analysed in relation to location and diameter of the vascular lesion, the clinical symptomatology, the type of the interventional procedure and the postoperative complications. A systematic review of the studies in literature was performed using medical databases PubMed and Medline. Results: In our study, we examined 117 true aneurysms and 39 pseudoaneurysms in the visceral and iliac arteries of 151 patients. All cases were treated using the percutaneous procedure, with technical success achieved in 95% of patients and organ preservation in 84.2% of cases. Following a review of the literature, we included 56 studies reporting data on 3,299 patients and 3,439 aneurysms. Of these, 79.2% were treated with an interventional radiological approach, achieving a technical success rate of 94.2%. Conclusions: In our experience, endovascular treatment of visceral and iliac aneurysms is feasible and safe, as this procedure has a high success rate, low operative risk and reduced morbidity.
