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).

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 |

The gold standard treatment of severe symptomatic AS is surgical aortic valve replacement. Mechanical valves were initially the prostheses of choice; with improvement of surgical technique and results, and increased durability of bioprosthetic valves, there has been a trend toward increasing use of bioprostheses. |

large-bore sheaths, arterial surgical cut-downs for access and closure are required. This study describes and reports the results of a
percutaneous technique using multiple Perclose devices (Closer-S, 6 Fr) for large arteriotomy closure.
Methods: Sixty-six patients (50 males; mean age 62.8±11.8 years) with endovascular stent-graft treatment (from Feb. 2004 |

Before performing end-to-side anastomosis, we attached a small partial clamp to the left common carotid artery, thereby maintaining adequate cerebral blood flow during perfusion. To date, ne |

Aortic proteolysis predisposes to dissection and aneurysm. Losartan may prevent aortic root dilation in Marfan syndrome. The Loeys-Dietz syndrome mandates early aortic intervention. Because genetic aor- topathies have a multicenter registry, further aortic molec- ular advances are likely. Acute intramural hematoma (IMH) may be due to aortic dissection with unrecognized micro- intimal |

(作者:George S.K. Funga,∗,[|] 刊发时间:2008-01)(查看:4536 下载:21) | 概述:In treating thoracic aortic diseases, endovascular repair involves the placement of a self-expanding stent-graft system across the diseased
thoracic aorta. Computational fluid dynamic techniques are applied to model the blood flow by numerically solving the three-dimensional
continuity equation and the time-dependent Navier–Stokes equations for an incompressible fluid. From our results, high blood pressure level
and high systolic slope of the pressure waveform will significantly increase the |
