概述:Acute aortic dissection is rarely seen in the patient with a previously repaired abdominal aortic aneurysm (AAA). 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 We report

概述:Compared with aneurysms that are limited to the mid and distal descending thoracic aorta, those that extend up to or into the transverse aortic arch are more challenging to repair with open techniques.

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

概述:Objective: The first combined endovascular and surgical approach for thoracoabdominal aortic aneurysm was performed 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

概述:Objective: We developed a novel method using anatomic markers along the thoracic aorta to accurately quantify 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

概述:Thoracic endovascular aortic repair (TEVAR) has become widely accepted as an important 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

概述:We used left common carotid artery cannulation for repair of type A aortic dissection in 2 patients for whom both femoral artery and axillary artery cannulation were thought to be more dangerous, due to dissection of the brachiocephalic trunk and left subclavian artery in association with abdominal stenosis. 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

概述:Purpose: To present early and midterm results after endovascular stent graft repair of patients with penetrating aortic 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). Follow-up sc

概述:Introduction: Recent studies suggest an increased risk of neurologic complications after coverage of the left subclavian 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. Methods: In the absence of any ra

概述:Endoleaks continue to be a challenge in the endovascular approach to aneurysm repair, both in the abdominal and thoracic aorta. 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

概述:Objective: Percutaneous aortic valve replacement is an emerging therapy for selected patients with severe aortic stenosis. 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.
