The advent of multidetector-row CT (MDCT) approximately 10 years ago has revolutionized the evaluation of the thoracic aorta. In a single breathhold, many thousands of images can be acquired as needed to answer important clinical questions. Coronary artery evaluation has been a major driving factor for the exponential advances in MDCT evolution, with a major by-product being improved |

To report the results of a systematic review of the literature and to provide evidence for the hybrid openendovascular repair (HOER) in patients with thoracoabdominal aortic aneurysms (TAAAs). Methods. A comprehensive literature review was performed and all studies identified that reported the results of HOER in patients with TAAA and information about primary technical and clinical success in evaluating the immediate and longterm complications such as neurological, renal and respirator |

H 刊发时间:2008-11)(查看:3036 下载:4) | 概述:Objectives: Extensive aneurysms of the ascending, arch, and descending thoracic aorta traditionally have been managed with a 2-stage "elephant trunk" procedure. Single-stage transmediastinal repairs have also been used, because in some patients the entire repair is not completed owing to either complications during first-stage repair or magnitude of the second-stage operation. Since 2006, second-stage elephant trunks have been preferentially completed with endovascular stent grafts in anatomical |

Klodell,Thom 刊发时间:2007-09)(查看:3026 下载:2) | 概述:Acute aortic dissection is a disease entity that is treated depending on the extent and location of involvement of the dissection flap. Type A dissection (involving the ascending aorta and/or aortic arch) is managed surgically, whereas type B dissection (involving only the descending aorta) is usually managed medically. Because these treatments are different and prompt intervention is critical to survival,accurate initial diagnosis is essential. Clinical changes may also develop that represent a |

(作者:K. Koseoglu,B. Cildag,S. Sen,M. Boga,M. Parildar 刊发时间:2006-02)(查看:3024 下载:2) | 概述:We report a case of an immuno-suppressed 49-year-old man with mycotic aneurysm of left subclavian artery. The aneurysm was diagnosed by computed tomography and digital subtraction angiography. Our choice for treatment was endovascular stent-graft implantation. After stent-graft implantation, type I endoleak was present because of the aneurysm had broad neck and, so, we implanted second stent-graft proximally to the first stent. The end of the procedure, there was a minimal type III endoleak into |

Elefteriades, MD 刊发时间:2008-05)(查看:3021 下载:21) | 概述:The vast database of the Yale Center for Thoracic Aortic Disease—which includes information on 3000 patients with thoracic aortic aneurysm or dissection, with 9000 catalogued images and 9000 patient-years of follow-up—has, over the last decade, permitted multiple glimpses into the “playbook” of this virulent disease. Understanding the precise behavioral features of thoracic aortic aneurysm and dissection permits us more effectively to combat this disease. |

(作者:W. Anthony Lee 刊发时间:2008-12)(查看:3018 下载:2) | 概述:Careful patient selection and case planning is critical to the early and late success of thoracic endovascular aortic aneurysm repair (TEVAR). It can be said that 90% of the battle is won or lost before stepping into the operating room. Although repair of an uncomplicated mid-descending thoracic aneurysm is fairly straightforward, most thoracic pathologies lie close to the arch vessels proximally or mesenteric vessels distally, or both. Meticulous attention to detail and proficiency in advanced |

Tometzki,M 刊发时间:2008-04)(查看:3014 下载:2) | 概述:Introduction: Aortic arch anomalies are common; however, the presence of concomitant pathology may present a complex management problem. Report: A 42 year old lady with anomalous right subclavian artery was found to have recurrent coarctation of the aorta and an aneurysm related to the previous repair. Management of the aneurysm was complicated by the proximity of subclavian artery origins. Bilateral subclavian-to-carotid transposition was undertaken to preserve antegrade vertebral artery flow, |

(作者:Mark D. Peterson, MD, PhD, Grayson H. Wheatley, II 刊发时间:2008-05)(查看:2968 下载:2) | 概述:Objective: Increasing experience with thoracic aortic stent grafts has led to a more aggressive approach to thoracic aortic pathologies in the distal aortic arch and proximal descending thoracic aorta. To increase the length of the proximal landing zone, it is sometimes necessary to cover the left subclavian artery with the thoracic stentgraft,introducing the risk of retrograde filling of the excluded aorta from the left subclavian artery. It is currently unclear how best to manage these patient |

Endovascular therapy may offer a minimally invasive alternative in the repair of the aortic injury. |

| (作者:Nimesh D. Desai, MD, PhD, and Alberto Pochettino[|]European Journal of Vascular and Endovascular S 刊发时间:2009-01)(查看:2946 下载:21) | 概述:DeBakey type I aortic dissections pose significant challenges in operative and long-term management of the arch and distal thoracic aorta. Concerns regarding management of complex tears extending to the arch and descending thoracic aorta, malperfusion syndromes, and late aortic dilation have provided an impetus to explore aortic repairs that involve stent-graft placement into the descending thoracic aorta in combination with promising but further study is warranted. |
