Outcomes of a Novel Single Branched Aortic Stent Graft for Treatment of Type B Aortic Dissection.

Background: Intervention on Type B dissection frequently requires landing the proximal edge of the stent graft between the left common carotid artery and left subclavian artery (LSA). The Gore® TAG® Thoracic Branch Endoprosthesis (TBE) is a technology which allows LSA preservation with a single internal branch.

Methods: This study was a prospective non-randomized single-arm clinical trial of patients with type B aortic dissection that were treated with the single branched device.

Five-year outcomes of endosuture aneurysm repair in patients with short neck abdominal aortic aneurysm from the ANCHOR registry.

Objective: Hostile aortic neck anatomies such as proximal short necks are known to put patients at an increased risk for type IA endoleaks, migration, and need for reinterventions. The Heli-FX EndoAnchor System was designed to improve seal of aortic stent grafts. Endosuture aneurysm repair (ESAR) using EndoAnchors with the Endurant stent graft has been shown to be safe and effective for the treatment of patients with short necks through one year.

Stent-Graft Fabrics Incorporating a Specific Corona Ready to Fenestrate.

In situ fenestration of endovascular stent-grafts has become a mainstream bailout technique to treat complex emergent aneurysms while maintaining native anatomical visceral and aortic arch blood supplies. Fabric tearing from creating the in situ fenestration using balloon angioplasty may extend beyond the intended diameter over time. Further tearing may result from the physiologic pulsatile motion at the branching site.

Laser Fenestration in TEVAR: Perspectives and Future Directions.

Endovascular aortic repair has been increasingly used to treat a multitude of thoracic aorticpathologies. When placement of a thoracic endograft necessitates coverage of one or more of the great vessels, in situ laser fenestration is a safe and effective option for supra-aortic trunk revascularization. Certain anatomic factors may render laser fenestration more technically challenging, particularly depending on aortic arch type and branch vessel characteristics.
