The lesion was treated by the implantation of a stent-graft. On release, the stent-graft dislocated into the aortic arch. Intraoperative angiogram showed free perfusion of the brachiocephalic trunk and left common carotid artery; however, an overstenting of the carotid artery was apparent.

Total arch grafts are too bulky to be inserted into a sheath catheter during usual stent grafting methods. An assembling method that uses a chain stitch enables the deployment of any type of stent graft into the distal aorta without the need for a sheath catheter. We describe how to safely assemble and use a branched arch stent graft. We consider this method to be beneficial in selected cases involving extensi |

In the first selective antegrade cerebral perfusion, and a Dacron graft is positioned down the descending aorta in an elephant trunk-like fashion with its proximal free margin sutured circumferentially to the aorta just distal to the left subclavian or left common carotd artery. With the graft serving as the new proximal landing zo |

Based on evaluation with computed tomography angiography (CTA), 21 custom-made branched stent grafts were designed for the selected patients. Two patients had associated bilateral aneurysms of the common iliac arteries, so an iliac branched de |

Czerny[|]European Journal of Vascular and Endovascular Surgery 刊发时间:2009-06)(查看:2621 下载:2) | 概述:For aneurysms and dissections involving the aortic arch, the traditional treatment is open surgical repair requiring cardiopulmonary bypass and deep hypothermic circulatory arrest. Reported mortality rates range from 7% to 17% and neurologic injury rates range from
4% to 12%. Since the first clinical applications of endovascular repair in the early 1990s, this less-invasive treatment modality has evolved steadily. For the treatment of aortic arch pathologies, combined open |

Methods: The subjects were 35 consecutive patients who received arch replacement with open stent grafting for type A acute aortic dissection between December 1997 and April 2002. The mean follow- |

A less invasive endovascular option is endovascular stent grafting using in situ fenestrations. After thoracic stent graft deployment in the arch, fenestrations are made for the major arch vessels. During this procedure, antegrad cerebral perfusion is maintained using a temporary bypass from the left femoral artery to both carotids perfusing both the ante |

repair.
Multibranched stent graft implantation eliminates aneurysm flow, preserves visceral perfusion, and avoids many of the physiologic stresses associated with other forms of repair. The results support an expanded role for this technique in the treatment of TAAA. |

The combination of open surgery and endovascular grafting may improve the morbidity and mortality of the patient population at risk.

There are patients, however, who will require a second distal operation despite this new technique due to progression of their aortic disease. It has been unclear whether the presence of the stented segment of the hybrid prosthesis results in unexpected tech |

They frequently require major surgical exposure through both the thoracic and the abdominal cavities, suprarenal or supraceliac aortic cross-clamping, and exposure of the visceral and renal arteries.
