Due to the limitations of the current technology, the endograft was deployed through a left ventricular transapical approach by using a left mini-thoracotomy |

Methods: The subjects were 65 consecutive patients who received arch replacement with an open stent graft for type A acute aortic dissection. CT scanning was performed at 1, 3, 12, |

Nevertheless, endovascular thoracic intervention began to be performed in Japan in the early 1990s, with homemade devices used in most cases. Many researchers have continued to develop homemade devices. We have participated in joint design and assess |

Design: 70 consecutive MDCTA of patients with TAAAs were analysed in relation to specific morphological characteristics.
Methods: The characteristics included potential stent landing zone lengths, arch angulation, thoraco-abdominal aorta angulation, branch vessel origin stenosis, acce |

We performed this feasibility study to determine if thin-film NiTi (Nitinol) could be used as a covering for stent grafts ranging from 16 mm to 40 mm in diameter. Specifically, we wished to dete |

Several publications document the technical feasibility of stent graft repair of aortic transection. We report our mid-term results of endovascular repair of thoracic aortic transections using covered stent grafts and compare this to a co- hort undergoing open repair during the same time period to demonstrate the shift in practice pattern at our institution.
Materials and methods. A retrospective review of pa- tients who sustained blunt thoracic transection was |

These changes may be important for proximal aortic stent graft fixation, sealing and durability. The objective of this study is to analyse the influence of different types of stent grafts on dynamic changes of the aneurysm neck.
Methods: Pre- and postoperative electrocardiography (ECG)-gated computed tomographic angiography (CTA) scans were obtained in 30 abdominal aortic aneur |

Bicknell, MD 刊发时间:2009-08)(查看:5906 下载:0) | 概述:Objective: Fenestrated stent grafting has allowed the treatment of complex thoraco-abdominal aneurysm disease via a totally endovascular approach, but the procedure can be technically challenging and time consuming. We investigated whether this procedure may be enhanced by remotely steerable robotic endovascular catheters.
Methods: A four-vessel fenestrated stent graft partially deployed within a computed tomography (CT)-reconstructed pulsatile thoraco-abdominal aneurysm sili |

(作者:Timothy A.M. Chuter, DM 刊发时间:2007-04)(查看:5840 下载:13) | 概述:The neck of a juxtarenal aneurysm is often too short for stable hemostatic stent-graft
implantation. Fenestrations (holes) in the stent-graft permit implantation at a more favorable
level by providing a route for flow to the renal arteries. In cases of pararenal and
thoracoabdominal aortic aneurysm, the aorta around the renal and visceral arteries is too
dilated for hemostatic contact with the wall of the stent-graft. There is a gap, which must
be bridged by a branch of the stent-graft. In |

opened the way to treat complex aortic aneurysms involving the visceral arteries. Early reports
on endovascular treatment of thoraco-abdominal aneurysms have demonstrated the feasibility
of the technique. Given the sparse literature, its safety has not been established yet.
Methods: A literature review was conducted, and the results of our own series of 30 patients

flow in patients with aneurysmal or short common iliac arteries. The aim of this study is to evaluate a single-center
experience with bSG for the IIA.
Methods. Twenty-two male patients (70 (IQR 65e79) years old) underwent EVAR with 23 bSG (1 bilateral repair)
between September 2002 and August 2007. Median AAA diameter was 52 (37e60) mm while common iliac diameter
