Thoracic stent-graft

Acta chirurgica Iugoslavica, 2007
The stent-graft is a device constructed from a stent and vascular graft and is inserted by means of an interventional procedure under imaging guidance. In 1986, Balko et al.1 reported the first stentgraft experiment, in which a Z stent covered with polyurethane was inserted into an animal aorta.

Spatial Configuration of Abdominal Aortic Aneurysm Analysis as a Useful Tool for the Estimation of Stent-Graft Migration [PDF]

Diagnostics, 2020
The aim of this study was to prepare a self-made mathematical algorithm for the estimation of risk of stent-graft migration with the use of data on abdominal aortic aneurysm (AAA) size and geometry of blood flow through aneurysm sac before or after stent-

Comparative Efficacy of Integrated Stent-Graft versus Conventional Covered Stent-Graft Alone in Type B Aortic Dissection: A Retrospective Study Focusing on Aortic Remodeling and Branch Perfusion [PDF]

Reviews in Cardiovascular Medicine
Background:To compare the early efficacy of an integrated stent-graft (16-cm covered stent combined with a 6-cm distal bare stent) versus a conventional covered stent-graft alone in patients with acute type B aortic dissection (TBAD), with a focus on ...

Stent Graft for Nephrologists [PDF]

Clinical Journal of the American Society of Nephrology, 2010
The role of the stent graft is emerging in the management of arteriovenous dialysis access. Physicians are incorporating this device in the management of three distinct problems--vein-graft anastomotic stenosis, pseudoaneurysm formation, and cephalic arch stenosis--with varying degrees of success.

Leg occlusion of the Ovation Alto stent graft main body caused by twisting of the stent graft: A case report

Journal of Vascular Surgery Cases and Innovative Techniques
The Ovation Alto stent graft is a unique endovascular abdominal aortic aneurysm repair device. A low-viscosity, radiopaque liquid polymer fills the rings located within the legs of the device.

Changes in aortic pulse wave velocity of four thoracic aortic stent grafts in an ex vivo porcine model. [PDF]

PLoS ONE, 2017
Thoracic endovascular aortic repair (TEVAR) has been shown to lead to increased aortic stiffness. The aim of this study was to investigate the effect of stent graft type and stent graft length on aortic stiffness in a controlled, experimental setting ...

Multi-objective design optimization of stent-grafts for the aortic arch

Materials & Design, 2023
Complications of thoracic endovascular aortic repair are closely related to the mechanical properties of implanted stent-grafts. Compared with straight vessels, the complex morphology of aortic arch imposes strict requirements on stent-graft properties ...

3D Stent Graft Guidance based on Tracking Systems for Endovascular Aneurysm Repair

Current Directions in Biomedical Engineering, 2021
In endovascular aneurysm repair (EVAR) procedures, the stent graft navigation and implantation is currently performed under a two-dimensional (2D) imaging based guidance requiring X-rays and contrast agent.
