The aim of this study is to analyze the risk factors associated with early and late mortality after thoracic endovascular aortic repair. |

(作者:J. van Prehn,F.J.V. Schlosser[|]European Journal of Vascular and Endovascular Surgery 刊发时间:2009-03)(查看:5593 下载:34) | 概述:Sizing of aortic endografts is an essential step in successful endovascular
treatment of aortic pathology, although consensus regarding the optimal sizing strategy is
lacking. Some proximal oversizing is necessary to obtain a seal between the stent graft and the
aortic wall and to prevent the graft from migrating, but excessive oversizing might influence
the results negatively. In this systematic review, we investigated the current literature to
obtain an overview of the risks and benefits |

This report compares long-term results with total arch replacement with frozen elephant trunk (FET) to ascending aortic or hemiarch replacement (AHR) for acute type A aortic dissection. Methods. The subjects were 120 consecutive patients, including 65 who received FET and 55 who had AHR for acute type A aortic dissection from 1997 to 2008. The late results after surgery were retrospectively compared between the FET and ARH groups. |

Radiologists performing arterial access procedures should be aware of when and how to use them, as well as the advantages and disadvantages of various devices, and any complications that may occur. This review intends to provide an overview of these devices, focusing on how they work, their efficacy in achieving hemostasis, any risks associated with their use, and our view as to which should be used for particular indications.

Harris[|]European Journal of Vascular and Endova 刊发时间:2010-01)(查看:5572 下载:4) | 概述:Objective: A prototype ready-to-fenestrate stent graft (RFSG) was designed with a fixed scallop, and eight potential fenestrations allowing for variation in the position of each renal artery (RA) relative to the superior mesenteric artery (SMA). We aimed to determine the proportion of juxtarenal aneurysms treatable using this potentially ‘off-the-shelf’ device. Methods: A total of 439 consecutive orders for custom-made devices were analysed, and posi- tions for potential fenestration |

Materials and methods: An elastic tube phantom mimicking the descending aorta was developed with the possibility to insert an aortic nitinol stent graft. Different flow patterns (constant, sinusoidal and pulsatile aortic flow) were applied by a gear pump. A two-dimensiona |

significantly by the boundary conditions and geometry. To assess these influencing factors, simulations using three different steady inlet
profiles and two geometries were run. The steady velocity inlet profiles (flat, parabolic and realistic) were used as input boundary conditions
with a constant pressure outlet for each model. The geometry of an out-of-plane r |
