title: Essential techniques for intraoperative composite endograft (CEG) formation in the treatment of abdominal aortic aneurysm.
abstract: The development of an ideal aortic stent graft continues to progress. New devices and techniques are expanding the use of endovascular repair in the treatment of abdominal aortic aneurysms (AAA). We present data with intraoperative composite endograft (CEG) techniques evaluating immediate and short-term compatibility of components and patients outcome. Twenty-five of 66 patients (38%) received intraoperative CEGs for AAA treatment. A total of 50 components were used to treat type I endoleaks, prevent graft limb kinking or treat associated iliac aneurysm. Nine of the components were used to manage type I proximal endoleaks. Forty-one components were used at the iliac limb for distal type I endoleak, hostile iliac anatomy, or graft limb support or to treat an associated iliac aneurysm. Two patients were left with a type I endoleaks at the iliac attachment site on completion of graft placement. With a mean follow-up of 11 months. Two of 25 patients had a type II endoleak at 6 months. One patient had type I endoleak at 1 year follow-up. CEGs are essential to treat endoleaks with a high technical success rate and expand the indications for treating infrarenal AAA. The component's short-term compatibility makes this method of stent graft placement safe.
