Flow-diverting stents for the treatment of arterial aneurysms

Abstract

Initial clinical experience with the use of FDSs in the treatment of visceral and peripheral aneurysms yielded satisfactory results in technical success, aneurysm thrombosis and shrinkage, and in patency of branch vessels. The results in aortic aneurysms are still under investigation. No aneurysm rupture has yet been described. There is a significant incidence of FDS thrombosis. Volume reduction of the aneurysm is a clearer evidence of the clinical success after treatment with FDSs than aneurysm thrombosis.

Open and endovascular treatment by covered and multilayer stents in the therapy of renal artery aneurysms: mid and long term outcomes in a single center experience

“…In patients with renal artery aneurysms involving a renal bifurcation similarly is possible an endovascular technique: in some cases a little arterial branches may be occluded. In the cases in which almost 1/3 of renal parenchyma is perfused by the involved branch, a multilayer stent is advised; in our experience this approach regained optimal results in preserving renal perfusion and to obtain aneurysmal exclusion (15). On the other hand, aneurysms located at the hilum are not suitable for a less invasive approach, both for the technical difficulties and the high risk of renal ischemia or aneurysm rupture.…”

ePTFE stent graft in non-steno-occlusive arterial disease: 2 centers retrospective study

“…Pretreatment angiography confirms the arteriovenous fistula between the right deep femoral artery and common femoral vein (b). Post-treatment angiography shows exclusion of arteriovenous fistula by deployment of Fluency stent graft (c) the treatment of visceral and peripheral aneurysms yielded satisfactory results [30].…”

Endovascular repair of a juxtarenal saccular aneurysm using the Multilayer Flow Modulator: report of the first case performed in a Public Hospital in Brazil

“…Successful clinical results in the form of thrombosis of the aneurysm, reduction of the aneurysm and patency of visceral branches were achieved in around 40% of aneurysms involving visceral arteries. 11,20 Although there are reports of reintervention in around 13.7% of cases, including intestinal resection and thrombosis in 8.3% of cases, and even rupture of the aneurysm, 21,22 the technique apparently appears to be promising. 20 One important limiting factor to use of this material is its cost, which is currently extremely high compared to conventional endoprostheses, particularly by Brazilian standards.…”
