We used computational fluid dynamic techniques to analyze the biomechanical factors associated with stent graft remodeling in these patients. |

combined surgical and endovascular technique for the
treatment of thoracic aortic aneurysms and dissections.
The technique is used to treat extensive aortic disease by
a single-stage procedure. Surgical outcomes and follow-
up data are summarized and analyzed. |

The function of these blood vessels has successfully been studied in the framework
of biology, physics, and imaging. |

complications resulting in immediate or late conversion to open repair. Methods: From November 1997 to May 2007, 28 patients underwent a
thoracic endovascular stent-graft procedure for acute symptomatic type B dissection at our institution. Indication for endovascular repair at our
department is a complicated course of type B dissection, including thoracic aortic rupture, |

Materials and methods: Electrocardiogram-gated computed tomography angiographywas performed during inspiratory breath-hold in 11 patients with CADB: Collimation 16mm×1mm,pitch 0.2, slice thickness 1mm, reconstruction increment 0.8mm. Multiplanar reformations were taken for 20 equidistant time instances through both ascending (AA |

challenge in a patient population with significant co-morbidity.
Report: We present a successful endovascular repair of an 8.4 cm aortic arch aneurysm, in a 74
year old man, who’s previous median sternotomy showed signs of delayed healing, precluding
open repair.
Discussion: Applied endovascular techniques obviated the need for aortic clamping, cardiac
bypass, or hypothermic circulatory arrest, via an approa |

Because its incidence is low, the natural history is unknown. We report data from the International Registry of Acute Aortic Dissection(IRAD), the largest group of patients treated for acute aortic dissections. The aim of this study was to identify clinical characteristics, therapeutic approaches, risk factors for mortality, in-hospital outcome, and long-term results o |

standard endovascular repair (EVR). This article reviews the outcomes of fenestrated technology
and makes a comparison with open repair. |
