Fenestrated and branched stent-grafting: a 5-years experience.
Fenestrated stent-grafts aim at treating short-necked aneurysms. As a result of customized fenestrations, patency of vital side branches such as the renal arteries and the superior mesenteric artery can be maintained, whilst positioning the graft over these aortic side branches. Over the years, the technique has been refined. Results in a few experienced centers are good, with excellent patency rates of targeted side branches. Suprarenal and thoraco-abdominal aneurysms can only be treated by endovascular means with branched grafts. This can be achieved with fenestrated grafts, but with the use of covered stents through the fenestrations, or by fully branched grafts. Both options are feasible and present with specific advantages and disadvantages. This report gives an overview of our 5-years experience with fenestrated and branched grafts, and discusses the following aspects of the technique: indications, technical principles, results, and limitations.
