Abstract

Introduction: Isolated Internal Iliac artery aneurysms are rare and asymptomatic condition that most of them are diagnosed incidentally. Due to the nonspecific symptoms of IIAAs, their deep anatomical location, and the probability of rupture, they can be fatal. Open surgery is the traditional treatment for IAAs, but open surgery can be technically challenging and Endovascular treatment of aneurysmal arteries may be a useful alternative to open surgery, as it can reduce post-operative mortality and morbidity. Case presentation and method: A 63 years old heavy smoker male presented with an accidentally findings in imaging, such as iliac aneurysm in abdominopelvic U٫S with no symptoms. CTА, showed bilateral CIA aneurysms (L:29 mm, R: 38 mm) and right side internal iliac artery aneurysm (8 cm) with healthy aorta. Due to absence of proper proximal landing zone for aneurysm in common iliac arteries, we decided to coil embolization of internal iliac with EVAR to treat patient. The procedure performed successfully with no Endo leak in completion angiography. Patient discharged 2 days after procedure with no complication. This case was reported in line with the SCARE criteria. Discussion: EVAR techniques usually involve stent graft placement, embolization, or revascularization of the IIA, which may include IIA stent graft implantation, the sandwich technique, and iliac branch devices (IBDs), and the IIA is preserved whenever possible. Because of unilateral coverage of internal iliac and minimal risk of pelvic ischemia, IBD was not required. We treated our case via coil embolization of internal iliac with EVAR. Conclusion: Elective treatment of isolated Internal Iliac artery aneurysms (IIAAs) with EVAR has been shown to be safe and effective. © 2025
