option for treatment of thoracic aortic diseases. Cross-sectional radiologic imaging plays a
crucial role for evaluating a patient’s candidacy for planning of the intervention and for
assessment of postprocedural results and complications of TEVAR. Recent advances in
imaging technologies, in part inspired by advances in stent-graft technology, have drastically
changed the character and role of pre- and po |

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

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 |

Harris[|]European Journal of Vascular and Endova 刊发时间:2010-01)(查看:5790 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 |

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.

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. |

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 |

ulcers (PAU).
Methods: Between January 1997 and March 2008, a total of 202 patients received thoracic aortic endografting in our
institution, 48 patients (32 men, median age 70 years, range, 48-89) with PAU. A retrospective analysis of these patients
was performed. Thirty-one patients (65%) showed an acute aortic syndrome (8 contained rupture, 23 symptomatic).
