An iliac artery aneurysm is characterized by arterial lumen dilatation which is more than 1.5 times greater than the normal diameter of the artery. In clinical practice, this pathology is rarely encountered, being associated with arterial hypertension and smoking, and more often observed in men. Its natural course inevitably leads to aneurysmal rupture. Treatment is only operative. Is admissible to use both open and endovascular techniques, with preference given to endovascular interventions using special linear endografts. Presented herein are two clinical case reports concerning endoprosthetic repair of an iliac artery aneurysm with a branch of the bifurcated stent graft Terumo Aortic Anaconda. The operative interventions had no complications in either peri- or postoperative periods. Our experience shows that endoprosthetic repair of an isolated aneurysm of the common iliac artery with a branch of the bifurcated stent graft Terumo Aortic Anaconda combines safety and efficacy and may be used by a wide range of vascular and roentgenoendovascular surgeons.
