There are few reports of this in the literature after open aneurysmec- tomy,1,2 and to our knowledge, only one report after endo- vascular AAA repair (EVAR).3 Retrograde dissection was thought to be the cause in this latter case, and this has also been reported after angioplasty or stenting of the thoracic and abdominal aortas, renal arteries, and iliac arteries.4-9

(作者:Timothy A.M. Chuter, DM 刊发时间:2007-04)(查看:5816 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 |

at our institution in 1998. We report a 10-year experience with a hybrid approach to thoracoabdominal aortic pathology.
Methods: Records of all patients undergoing a combined endovascular and surgical approach to thoracoabdominal aortic
pathology were reviewed. Presenting symptoms, perioperative morbidity and mortality, sequence (single versus two
stages), and late results were |

longitudinal and circumferential cyclic strain in nondiseased thoracic aortas during the cardiac cycle and to compute
age-related changes of the human thoracic aorta.
Methods: Changes in thoracic aorta cyclic strains were quantified using cardiac-gated computed tomography image data of
14 patients (aged 35 to 80 years) with no visible aortic pathology (aneurysms or dissection). We me |

option for treatment of thoracic aortic diseases. Cross-sectional radiologic imaging plays a
crucial role for evaluating a patient’s candidacy for planning of the intervention and for
assessment of postprocedural results and complications of TEVAR. Recent advances in
imaging technologies, in part inspired by advances in stent-graft technology, have drastically
changed the character and role of pre- and po |

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).

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 |

artery (LSA) during thoracic endovascular aortic repair (TEVAR). The preventative role of preoperative revascularization
of the LSA using carotid–subclavian bypass or transposition remains controversial. We assessed this increased risk and the
role of revascularization by undertaking a systematic review and meta-analysis of the literature.

Some of these leaks are related to anatomic factors and patient selection, others are device related, and some (especially type II leaks) appear intrinsic to the endovascular approach. Certain endoleaks require treatment as soon as they are detected due to continued pressurization of the aneurysm sac, while the need for treatment of others remains controversial. Using e |

Preoperative imaging of the aortic root facilitates sizing and deployment of the percutaneous aortic valve replacement device. We compared morphologic characteristics of the aortic root in patients with aortic stenosis versus elderly gender-matched controls using multidetector computed tomography. |
