Protocol for Guos aortIc Arch recoNstrucTion: a prospective, multicentre and single-arm study to evaluate the safety and efficacy of the WeFlow-Arch modular inner branch stent-graft system for aortic arch lesions (GIANT study)
This study aims to evaluate the safety and efficacy of the novel modular branch stent-graft system in patients with aortic arch lesions who are unsuitable for open aortic arch replacement. Methods and analysis This prospective, multicentre, single-arm, clinical trial will enrol 80 patients with aortic arch lesions requiring intervention, namely, true aortic arch aneurysms, pseudo-aortic arch aneurysms and penetrating ulcers involving the aortic arch. Clinical information and CT angiography (CTA) images will be collected and analysed to investigate the safety and efficacy of the novel modular branch stent-graft system. Pat...

Combined Stroke and Spinal Cord Ischemia in Hybrid Type I Aortic Arch Debranching and TEVAR and the Dual Role of the Left Subclavian Artery
AORTIC ARCH PATHOLOGY, as a part of acute aortic syndrome, is a difficult clinical problem to address. Whether it presents as an intramural hematoma with impending rupture, isolated aneurysmal disease, or acute localized dissection, it creates a clinical challenge to the perioperative team. Some of the difficulty stems from determining the best operative strategy, either an open approach, total endovascular repair, or a hybrid of the two. Hybrid aortic arch repair involves two steps: open aortic branch revascularization and endovascular aortic repair.

Medtronic touts study data for thoracic aortic stent
Medtronic (NYSE:MDT) said that its thoracic stent graft for the treatment of a potentially deadly blunt-force chest injury performed well five years after implantation, according to a new study. The Rescue study of the long-term durability, safety, and efficacy of the Medtronic’s Valiant Captivia thoracic stent graft system for blunt thoracic aortic injury (BTAI) was presented at The Society of Thoracic Surgeons annual meeting in San Diego this week. It was the first five-year, industry-issued dataset ever reported for patients with aortic transections undergoing thoracic endovascular aortic repair (TEVAR). BTAI is...

Gore Wins 3 Nods for Molding and Occlusion Balloon
W.L. Gore & Associates has won approvals and clearances from a wide variety of regulatory bodies for its Molding and Occlusion Balloon. The technology has received FDA clearance; a CE mark; and approval from the Japanese Ministry of Health, Labour, and Welfare. The Flagstaff, AZ-based company’s device is a compliant polyurethane balloon catheter. The Molding and Occlusion Balloon was designed in close collaboration with clinicians to assist in the expansion of self-expanding stent grafts or to temporarily occlude large-diameter vessels. Gore said the new device meets all endovascular aortic repair (EV...

Mortality and reintervention following elective abdominal aortic aneurysm repair
Conclusions: Results of this meta-analysis demonstrate that the 30-day all-cause mortality rate is higher with open than with EVAR repair; however, there is no statistical difference in the long-term all-cause and cause-specific mortality between both groups. The reintervention rate attributable to procedural complication was higher in the EVAR group. Because of the equivalency of long-term outcomes and the short-term benefits of EVAR, an endovascular-first approach to AAAs can be supported by the meta-analysis.
