ABSTRACT
OBJECTIVE: Isolated aneurysms of the internal iliac arteries (IIIAA) are a rare variant of aorto-iliac aneurysms, representing only 0.3-0.5% of intra-abdominal aneurysms. Bilateral isolated hypogastric artery aneurysms are even more rare. The rarity of IIIAA has determined the absence of a high level of evidence about its treatment. METHOD: We present a case of bilateral isolated internal iliac artery aneurysms treated in two stages by positioning GORE VIABAHN VBX Balloon Expandable Endoprosthesis large, chosen for the possibility to adapt it to the anatomical diameter variations between the hypogastric artery and the posterior trunk, which was the distal landing zone chosen in both sides. CONCLUSION AND RESULTS: Total patency was detected 1 year after surgery in both sides. No buttock claudication, erectile dysfunction and/or signs of bowel ischaemia were referred. Preserving the hypogastric flow is an important goal in isolated hypogastric arteries aneurysms' treatment and covered stenting surely represents a valid therapeutical choice.
