Little is known about TEVAR’s nationwide effect on patient outcomes. We evaluated nationwide data regarding the short-term outcomes of TEVAR and open aortic repair (OAR) procedures performed in the United States during a 2-year period.
Methods: From the Nationwide Inpatient Sample data, we identified patients who had undergone surgery for an isolated descending tho |

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

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

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 |

The technique uses division of the ligamentum arteriosum and a series of circumferential pledgeted traction stitches on the segment of aorta selected for the distal anastomosis. |

The availability of multi-row detector CT has facilitated early diagnosis and incorporation of minimally invasive endograft repair for traumatic
aortic injury has improved mortality and paraplegia rates. This review evaluates the available data on stent-graft repair of acute blunt traumatic aortic injury and traumatic great vessel injury with regard to safety and efficacy in comparison with |
