JOURNAL OF VASCULAR SURGERY. Experience matters more than specialty for carotid stenting outcomes

Michael D. Sgroi, MD, Geoffrey C. Darby, BS, Nii-Kabu Kabutey, MD, Andrew R. Barleben, MD, John S. Lane III, MD, Roy M. Fujitani, MD

Objective: The introduction of carotid stenting has led to a rapid rise in the number of vascular specialists performing this procedure. The Carotid Revascularization Endarterectomy vs Stenting Trial (CREST) has shown that carotid stenting can be performed with an equivalent major event rate compared with carotid endarterectomy. However, there is still controversy about the appropriate training and experience required to safely perform this procedure. This observational study examined the performance of carotid stenting with regard to specialty and case volume.

JOURNAL OF VASCULAR SURGERY. Type Ia endoleaks after fenestrated and branched endografts may lead to component instability and increased aortic mortality

Adrian O`Callaghan, MB, Roy K. Greenberg, MD, Matthew J. Eagleton, MD, James Bena, MS, Tara Marie Mastracci, MD

Objectives: Fenestrated and branched endografts allow for proximal sealing zone extension into or above the visceral aorta to optimize landing in healthy aorta. We describe the incidence, causes, and implications of proximal endoleak development in patients undergoing complex endovascular aortic aneurysm repair.

JOURNAL OF VASCULAR SURGERY. Deterministic effects after fenestrated endovascular aortic aneurysm repair

Melissa L. Kirkwood, MD, Gary M. Arbique, PhD, Jeffrey B. Guild, PhD, Carlos Timaran, MD, Jon A. Anderson, PhD, R. James Valentine, MD

Background: Endovascular aortic aneurysm repairs (EVARs) with fenestrated (FEVAR) stent grafts are high radiation dose cases, yet no skin injuries were found retrospectively in our 61 cases with a mean peak skin dose (PSD) of 6.8 Gy. We hypothesize that skin injury is under-reported. This study examined deterministic effects in FEVARs after procedural changes implemented to detect skin injury.

Brant W. Ullery, MD, Ga-Young Suh, PhD, Jason T. Lee, MD, Brian Liu, BS, Robert Stineman, BS, Ronald L. Dalman, MD, Christopher P. Cheng, PhD

Objective: This study quantified the geometry and respiration-induced deformation of abdominal branch vessels and stents after fenestrated (F-) and snorkel (Sn-) endovascular aneurysm repair (EVAR).

JOURNAL OF VASCULAR SURGERY. Role of type II endoleak in sac regression after endovascular repair of infrarenal abdominal aortic aneurysms

Jared Kray, DO, Spencer Kirk, DO, Jan Franko, MD, PhD, David K. Chew, MD

Objective: Endovascular repair (EVAR) of infrarenal aortic aneurysms (AAA) is increasingly used in patients with suitable aortic morphology conforming to device-specific instructions for use. Despite improvements in graft design, type II endoleak (EL-2) from the inferior mesenteric artery (EL-IMA) or the lumbar artery (EL-LA) remains the Achilles´ heel of EVAR. The objective of this study was to evaluate the natural history of the AAA sac after EVAR. We hypothesized that persistent EL-2 would be associated with inferior AAA sac volume regression.

JOURNAL OF VASCULAR SURGERY. Outcomes of endovascular abdominal aortic aneurysm repair in high-risk patients

Sungho Lim, MD, Pegge M. Halandras, MD, Taeyoung Park, PhD, Youngeun Lee, BA, Paul Crisostomo, MD, Richard Hershberger, MD, Bernadette Aulivola, MD, Jae S. Cho, MD

Objective: Although the endovascular aneurysm repair trial 2 (EVAR-2) demonstrated no benefit of EVAR in high-risk (HR) patients, EVAR is still performed widely in this patient cohort. This study compares the midterm outcomes after EVAR in HR patients with those in normal-risk (NR) patients. In turn, these data are compared with the EVAR-2 data.

AMERICAN HEART JOURNAL. Drug-coated balloons to improve femoropopliteal artery patency: Rationale and design of the LEVANT 2 trial

Michael R. Jaff, DO, Kenneth Rosenfield, MD, Dierk Scheinert, MD, Krishna Rocha-Singh, MD, James Benenati, MD, Mark Nehler, MD, Christopher J. White, MD

Background: Atherosclerotic peripheral artery disease (PAD) is common and results in limitations in quality of life and potential progression to limb loss. Options for therapy include medical therapy, supervised exercise, surgical revascularization, and, more recently, endovascular therapies to restore arterial perfusion to the limb.

Abrahamsen, MS‡; Suzanne Goldberg, MSN‖‖; Alan T. Hirsch, MD††

Background: Treatment for claudication that is due to aortoiliac peripheral artery disease (PAD) often relies on stent revascularization (ST). However, supervised exercise (SE) is known to provide comparable short-term (6-month) improvements in functional status and quality of life. Longer-term outcomes are not known.
