%X Isolated aneurysms of the iliac arteries are relatively rare conditions that traditionally have been treated by surgical reconstruction. We report our experience with endovascular treatment of iliac artery aneurysms (IAAs) with Anaconda stent graft limb. Two male patients were found to have 4.5 and 3.6£¿cm isolated common IAAs, respectively. The endograft was successfully advanced and deployed precisely to the intended position in both cases. In one case the internal iliac artery was embolized. No type I or II endoleak was observed immediately after the procedure. In one patient postimplantation fever (>38¡ãC) and gluteal claudication occurred. After 2£¿years followup both iliac endovascular stent grafts are patent and without endoleak. Endovascular treatment with Anaconda limb stent graft seems to be a safe and feasible alternative to open surgery. 1. Introduction Isolated aneurysms of the iliac arteries are relatively rare representing 2% to 7% of all intra-abdominal aneurysms [1, 2]. Iliac artery aneurysms (IAAs) are most frequently localized in the common or internal iliac artery (IIA) in combination with an abdominal aortic aneurysm. Aged men are most commonly affected and the etiology is usually atherosclerotic. Most of the patients with IAAs are asymptomatic and diagnosed incidentally. Elective repair has been recommended for IAAs with diameter greater than 3£¿cm to reduce the risk of rupture. Traditionally they have been treated by surgical reconstruction [3, 4]. The development of new endovascular devices offers alternative therapies [5]. We report our experience in endovascular treatment of isolated iliac artery aneurysms with the Anaconda limb stent graft. 2. Case Reports 2.1. Case 1 A 74-year-old obese man with chronic obstructive pulmonary disease, hyperlipidemia, and extensive smoking history was referred to our department because of an aneurysmal dilatation of the right common iliac artery (RCIA) detected on an abdominal ultrasound. A contrast-enhanced abdominal computed tomography (CT) demonstrated an aneurysm of the RCIA with diameters of (Figure 1(a)). The length of the aneurysm neck proximally was 18£¿mm and the ipsilateral IIA was thrombosed. The external iliac artery (EIA) was 13£¿mm in diameter with mild calcifications and tortuosity.
