Introduction: Endovascular repair of aortic (AAA) and iliac artery aneurysms requires introduction and deployment of large bore devices (> 16 F) through surgical exposure of the femoral artery. The Prostar XL ® arterial suture system allows the introduction of such devices without the need for surgical exposure. Aim: To report our initial experience with percutaneous arterial closure during aneurysm endografting. Methods: We reviewed records and datábase of patients treated with this technique between October2003 and April 2008. Results: We treated 22 patients with this technique (20 men and 2 women, average age 72 years). Sixteen had AAA, 3 iliac artery aneurysm, 1 hypogastric aneurysm and two for endoleak repair. The percutaneous closure device was used in 37 femoral arteries. In 7 patients (31,8%) the operation was completed entirely under local anaesthesia. The diameter of the devices ranged between 16 and 23 F. Technical success was obtained in 34 arteries (92%). Three arteries required surgical repair due to inadequate haemostasis (sheaths 18, 21, and 21 F). There was no operative mortality. During follow-up (mean 12,6 months, range 1-53) no false aneurysm or infection at the puncture site has been registered and the patients remain free of complications. Discussion: Percutaneous arterial closure in endovascular aneurysm repair is a safe, minimally invasive and effective procedure which allows resolving theses serious conditions in selected patients.
