JOURNAL OF VASCULAR SURGERY. Durability of the balloon-expandable covered versus bare-metal stents in the Covered versus Balloon Expandable Stent Trial (COBEST) for the treatment of aortoiliac occlusive disease

Bibombe P. Mwipatayi, MMed (Surg), FCS (SA), FRACS, Surabhi Sharma, MBBS, Ali Daneshmand, MD, Shannon D. Thomas, BMedSc, FRACS, Vikram Vijayan, MRCS, FRCS, Nishath Altaf, PhD, FRCS, Marek Garbowski, MB BS, FRACS, Mark Jackson, MD, FRACS on behalf of the COBEST co-investigators

Objective: The Covered vs Balloon Expandable Stent Trial (COBEST) is the first multicenter trial to investigate the patency of covered stents (CSs) and bare-metal stents (BMSs) in the treatment of aortoiliac arterial disease. The short-term results demonstrated that CSs were superior to BMSs in maintaining patency for TransAtlantic Inter-Society Consensus (TASC) C and D lesions at 18 months and were equivalent to BMSs for TASC B lesions. The current study was conducted to determine if the initial patency advantage of CSs over BMSs was sustained at the 5-year follow-up.

JOURNAL OF VASCULAR SURGERY. Conversion from endovascular to open abdominal aortic aneurysm repair

Klaas H.J. Ultee, BSc, Peter A. Soden, MD, Sara L. Zettervall, MD, MPH, Jeremy Darling, BA, Hence J.M. Verhagen, MD, PhD, Marc L. Schermerhorn

Background: Previous studies have found conflicting results regarding the operative risks associated with conversion to open abdominal aortic aneurysm (AAA) repair after failed endovascular treatment (endovascular aneurysm repair [EVAR]). The purpose of this study was to assess the outcome of patients undergoing a conversion, and compare outcomes with standard open AAA repair and EVAR. In addition, we sought out to identify factors associated with conversion.

Objective: This study reports our initial experience with the Gore Hybrid Vascular Graft (GHVG; W. L. Gore & Associates, Flagstaff, Ariz) for staged hybrid open renovisceral debranching and endovascular aneurysm repair in patients affected by thoracoabdominal aortic aneurysms and pararenal abdominal aortic aneurysms (PAAAs).

JOURNAL OF VASCULAR SURGERY. Impact of age and urgency on survival after thoracic endovascular aortic repair

Paola De Rango, MD, PhD, Giacomo Isernia, MD, Gioele Simonte, MD, Enrico Cieri, MD, PhD, Alessandro Marucchini, MD, Luca Farchioni, MD, Fabio Verzini, MD, PhD, FEBVS, Massimo Lenti, MD, PhD

Objective: Elderly patients are often turned down from receiving treatment for descending thoracic aortic diseases (DTADs) because of the uncertain benefits, especially in acute settings. This study investigated the impact of old age and timing of thoracic endovascular aortic repair (TEVAR) on outcomes of DTAD in patients older than 75 years of age.

JOURNAL OF VASCULAR SURGERY. The impact of endovascular aneurysm repair on mortality for elective abdominal aortic aneurysm repair in England and the United States

Alan Karthikesalingam, PhD, Peter J. Holt, PhD, Alberto Vidal-Diez, BSc, Sandeep S. Bahia, BSc, MBBS, Benjamin O. Patterson, PhD, Robert J. Hinchliffe, MD, Matthew M. Thompson, MD

Background: Procedural mortality is of paramount importance for patients undergoing elective abdominal aortic aneurysm (AAA) repair. Previous comparative studies have demonstrated international differences in the care of ruptured AAA. This study compared the use of endovascular aneurysm repair (EVAR) and in-hospital mortality for elective AAA repair in England and the United States.

JOURNAL OF VASCULAR SURGERY. Open abdominal aortic aneurysm repair is still necessary in an era of advanced endovascular repair

Sophia Khan, MD, Joseph V. Lombardi, MD, Jeffrey P. Carpenter, MD, Jose Trani, MD, James B. Alexander, MD, Francis J. Caputo

Objective: Recent advances in endovascular aneurysm repair have overcome substantial anatomic barriers associated with short and challenging necks. With greater range to treat more difficult anatomy from an endovascular approach, one would assume the need of open surgical repair (OSR) would be diminished. The purpose of our study was to determine the need for OSR for abdominal aortic aneurysms, in a tertiary academic setting, with a moderate volume (10-15 cases/year) of fenestrated endografting being performed.
