Endovascular treatment of pararenal aortic aneurysms

Endidovascular procedures have emerged as an attranative technique for the repair of abdominal arotic aneury, sms with an increasing popularity and diffusion. even if technology progresses are developing more and more efficient grafts and devices, at the ment is still not applicable to all patients.the most common reason for patient exclusion remain an proximal implantation site. 'endografts with suprarnal fixation were studied for solving the problem of the proximal neck but results seem to he not so encouraging. At the moment pararenal aortic aneury-sms. involving ostia of renal or visceral arteries, are usually excluded from endotutscidar treatment. the solution could be a custom-made graft for each single patient with fenestrations or branches for renal and visceral arteries. 1 he first clinical use of a fenestrated graft was by Park in 1996 and some groups are now studying different kinds of grafts, both in experimental and clinical studies, which are opening attractive new posibilities. At present results are only preliminary but this would be the first step towards the potential substitution of the entire aorta through oidova scular techniques. Copyright © 2004 GEM s.r.l.
