概述:Background: Endovascular techniques using various stent-graft systems are now available to treat aortic disease. Because stent-grafts need 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

概述:My colleagues and I propose a simple and reproducible technique to achieve optimal exposure and mobilization of the distal aortic arch and proximal descending thoracic aorta in the first stage of the elephant trunk procedure. The technique uses division of the ligamentum arteriosum and a series of circumferential pledgeted traction stitches on the segment of aorta selected for the distal anastomosis.

概述:Patients with extensive aortic aneurysms involving the ascending aorta, aortic arch, and the descending aorta are still considered to be a challenge for many cardiovascular surgeons.

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:Advances in endovascular technology have led to the introduction of fenestrated stents to treat juxtarenal aneurysms (JRAs), previously deemed unsuitable for standard endovascular repair (EVR). This article reviews the outcomes of fenestrated technology and makes a comparison with open repair.

概述:Significant stent graft remodeling commonly occurs after endovascular repair of thoracic aortic dissections because of continuing expansion of the true lumen.A suboptimal proximal landing zone, minimal oversizing, and lack of a healthy distal attachment site are unique factors affecting long-term stent graft stability. We used computational fluid dynamic techniques to analyze the biomechanical factors associated with stent graft remodeling in these patients.

概述:In treating thoracic aortic diseases, endovascular repair involves the placement of a self-expanding stent-graft system across the diseased thoracic aorta. Computational fluid dynamic techniques are applied to model the blood flow by numerically solving the three-dimensional continuity equation and the time-dependent Navier–Stokes equations for an incompressible fluid. From our results, high blood pressure level and high systolic slope of the pressure waveform will significantly increase the

概述:Purpose: The purpose of this study was to characterize the heartbeat-related displacement of the thoracic aorta in patients with chronic aortic dissection type B (CADB). Materials and methods: Electrocardiogram-gated computed tomography angiographywas performed during inspiratory breath-hold in 11 patients with CADB: Collimation 16mm×1mm,pitch 0.2, slice thickness 1mm, reconstruction increment 0.8mm. Multiplanar reformations were taken for 20 equidistant time instances through both ascending (AA

概述:Questions have risen regarding procedural indications, techniques, and outcomes for hybrid arch procedures. We performed a meta-analysis to benchmark this inno- vative approach. Studies and case reports involving hy- brid aortic arch procedures listed through May 2008 were reviewed (n 718). End points were 30-day mortality, stroke, paraplegia, and endoleak rates. A total of 15 studies with 463 patients were included in the meta- analysis. Overall 30-day mortality was 8.3%.

概述:An aortic stent graft is frequently used to cure an abdominal aortic aneurysm(AAA).It is critical to accurately fit the size and shape of the stent graft to the target region on the aorta. Proper sizing and shaping require the measurement of the orthogonal diameter of the target region from medical images. The present study aimed to acquire an accurate three-dimensional(3D) reconstruction of the aorta to determine the shape fo the cross-sectional area where the stent graft would be implanted. A
