Abstract
Isolated internal iliac artery (IIA) aneurysms are relatively uncommon. Isolated IIA aneurysms traditionally have been treated by surgical reconstruction. We report our experience with endovascular treatment of isolated IIA aneurysm.

We describe our experience of an isolated IIA aneurysm case that we treated with a branched stentgraft, which is in general a rarely performed procedure
Summary
An isolated aneurysm of the IIA is relatively uncommon and is generally asymptomatic. The left common iliac artery showed an aneurysmatic dilation of a nearly 3 cm segment reaching proximally, with a maximum diameter of 18 mm where a 2 mm thrombus was seen. The distal end of the stent-graft main body was placed to cover the aneurysm proximally and to appropriately guide the IIA. The guidewire that was taken out of the vessel by a cross-over approach and via a left arteriotomy was used to lead the vascular sheath to the proximal end of the stent-graft at the aortoiliac level. The distal end of the vascular sheath that was inserted via a left arteriotomy, was placed at the level of the stent-graft main body. Via a left femoral approach, the guidewire was led through the internal iliac branch of the stent-graft main body and was placed in the right IIA where the internal iliac limb was positioned
