BERGOEING R, MICHEL et al. Fenestrated endografts for the treatment of complex aortic aneurysms: Report of two cases. Rev Chil Cir [online]. 2011, vol.63, n.5, pp.519-523. ISSN 0718-4026. http://dx.doi.org/10.4067/S0718-40262011000500014.
In the last decade endovascular repair of infrarenal aortic aneurysms (EVAR) has become increasingly popular. However, until recently patients with juxtarenal abdominal aortic aneurysms (JAAA) or with thoracoabdominal aortic aneurysms (TAA) were not candidates for EVAR due to the lack of an adequate landing zone to deploy the endograft. Because of considerable morbidity and mortality that traditional open surgery of these aneurysms entail, new endografts with fenestrations and branches have been developed to treat these patients. We present our initial experience with two cases, both male with coronary artery disease considered high-risk for traditional open repair. The first patient has a 4.1 cm sacular JAAA; it is repaired with a fenestrated endograft with branches for both renal arteries (RA), superior mesenteric artery (SMA) and a scallop for the celiac trunk (CT). The second patient has a 5.9 cm TAA with a previous aorto bifemoral bypass; because the CT is chronically occluded it is repaired with a fenestrated endograft with branches for both RA and SMA. In both patients post operative course was uneventful. Follow-up at 11 months and 30 days respectively, show adequate exclusion of the aneurysm with patency of all revascularized vessels. This new therapeutic procedure allows treatment of high-risk patients with complex aortic aneurysms in whom conventional repair entails a prohibitive surgical risk.
