Method: The branches were constructed in situ by attaching a covered stent (Fluency Plus Tracheobronchial Stent Graft; Bard Peripheral Vascular, Tempe, Ariz) to each of four caudally-oriented cuffs on custom-made stent grafts. Pre- and postoperative computed tomography (CT) scans of 38 consecutively treated patients were analyzed using a three- |

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 |

Radiologists performing arterial access procedures should be aware of when and how to use them, as well as the advantages and disadvantages of various devices, and any complications that may occur. This review intends to provide an overview of these devices, focusing on how they work, their efficacy in achieving hemostasis, any risks associated with their use, and our view as to which should be used for particular indications.

treatment of aortic pathology, although consensus regarding the optimal sizing strategy is
lacking. Some proximal oversizing is necessary to obtain a seal between the stent graft and the
aortic wall and to prevent the graft from migrating, but excessive oversizing might influence
the results negatively. In this systematic review, we investigated the current literature to
obtain an overview of the risks and benefits |

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 |
