Anand Prasad MD, FACC, FSCAI1,*, Carolina Ortiz-Lopez MD1, David M. Kaye MBBS, PhD, FRACP, FACC, FESC2, Melissa Byrne PhD2, Shane Nanayakkara MBBS2, S. Hinan Ahmed MD, FACC, FSCAI1, Steven R. Bailey MD, FACC, MSCAI1, Roxana Mehran MD, FACC, FSCAI3, Salil Sethi MD1, Avantika Banerjee BS1 andMarvin Eng MD, FACC, FSCAI1

Background: The AVERTTM Contrast Modulation System (AVERT) (Osprey Medical, MN) is designed to reduce contrast volume administration during angiography. The AVERT provides an adjustable resistance circuit which decreases the pressure head delivering contrast towards the patient. The AVERT has not been previously studied in patients undergoing peripheral digital subtraction angiography (DSA). The purpose of this study was (1) to evaluate contrast savings with the AVERT and (2) to evaluate the ability to generate clinically acceptable DSA images in the process. To better define the mechanism of action in the peripheral circulation, we also developed a bench model to study the effects of the AVERT on the hydrodynamics of contrast delivery.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Peripheral Vascular Disease. Safety and Effectiveness of Stent Placement for Iliofemoral Venous Outflow Obstruction

Mahmood K. Razavi, MD, Michael R. Jaff, DO and Larry E. Miller, PhD

Background: Endovenous recanalization of iliofemoral stenosis or occlusion with angioplasty and stent placement has been increasingly used to maintain long-term venous patency in patients with iliofemoral venous outflow obstruction. The purpose of this systematic review and meta-analysis was to determine safety and effectiveness of venous stent placement in patients with iliofemoral venous outflow obstruction.

JOURNAL OF VASCULAR SURGERY. Treatment of iliac artery bifurcation aneurysms with the second-generation straight iliac bifurcated device

Andreas G. Loth, MD, Guido Rouhani, MD, Sameer A. Gafoor, MD, Horst Sievert, MD, PhD, Wolf J. Stelter, MD, PhD

Background: There are few long term studies to show the safety and efficacy of iliac artery aneurysm exclusion, especially in regards to the straight iliac branched device. The objective of our study was to add our data with a mean follow-up of 32 months to the existing data available.

JOURNAL OF VASCULAR SURGERY. Evaluation of the Zenith low-profile abdominal aortic aneurysm stent graft

Jonathan Sobocinski, MD, PhD, Florent Briffa, MD, Peter J. Holt, MD, FRCS, Teresa Martin Gonzalez, MD, Rafaëlle Spear, MD, PhD, Richard Azzaoui, MD, Blandine Maurel, MD, PhD, Stéphan Haulon, MD, PhD

Background: Low-profile (LP) stent grafts are now commercially available in Europe for endovascular aortic aneurysm repair (EVAR). In this study the midterm outcomes and characteristics of patients treated with this last generation of stent grafts were compared with a cohort of patients treated with “standard-profile” (SP) stent grafts.

JOURNAL OF VASCULAR SURGERY. Performance of the Endurant stent graft in patients with abdominal aortic aneurysms independent of their morphologic suitability for endovascular aneurysm repair based on instructions for use

Konstantinos P. Donas, MD, Giovanni Torsello, MD, Kristin Weiss, MD, Theodosios Bisdas, MD, Markus Eisenack, MD, Martin Austermann, MD

Objective: The aim of this study was to prospectively evaluate the early and late 7-year experience with the Endurant bifurcated stent graft system (Medtronic, Santa Rosa, Calif) in patients with abdominal aortic aneurysms.

JOURNAL OF VASCULAR SURGERY. Management of late main-body aortic endograft component uncoupling and type IIIa endoleak encountered with the Endologix Powerlink and AFX platforms

Afshin A. Skibba, MD, James R. Evans, MD, David Tyler Greenfield, MD, Heesuk Richard Yoon, MD, Tony Katras, MD, Kenneth Ouriel, MD, Daniel S. Rush, MD

Objective: Junctional component separation producing type IIIa endoleak after endovascular abdominal aortic aneurysm repair (EVAR) is an uncommon but serious complication requiring unanticipated reinterventions. This retrospective study analyzed main-body EVAR component uncoupling and type IIIa endoleaks encountered with Powerlink and AFX (Endologix Inc, Irvine, Calif) endografts during an 8-year period.

JOURNAL OF VASCULAR SURGERY. Multicenter retrospective investigation into migration of fenestrated aortic stent grafts

Andrew England, PhD, Marta García-Fiñana, PhD, Richard G. McWilliams, FRCR, EBIR, Collaborator

Objective: Fenestrated stent grafts are subject to the same hemodynamic forces that have resulted in migration of standard infrarenal stent grafts. Outcome data for fenestrated endovascular aneurysm repair consist of short-term and midterm efficacy studies where migration was generally poorly investigated. This study investigated the migration of fenestrated stent grafts in patients treated by fenestrated endovascular aneurysm repair in the United Kingdom.

JOURNAL OF VASCULAR SURGERY. Aneurysmal degeneration of the thoracoabdominal aorta after medical management of type B aortic dissections

Christopher A. Durham, MD, Nathan J. Aranson, MD, Emel A. Ergul, MS, Linda J. Wang, MD, Virendra I. Patel, MD, MPH, Richard P. Cambria, MD, Mark F. Conrad, MD, MMSc

Background: Patients with uncomplicated type B aortic dissections who are managed medically are at risk of aortic aneurysmal degeneration over time. However, the effect of improvement in antihypertensive medications and stricter blood pressure control is unknown. The goal of this study was to determine the rate of aneurysmal degeneration in a contemporary cohort of patients with medically treated type B dissection.

JOURNAL OF VASCULAR SURGERY. Three-year outcome of the heparin-bonded Viabahn for superficial femoral artery occlusive disease

Bahar Golchehr, MD, Rombout Kruse, MD, PhD, Laurens A. van Walraven, MD, Mare M.A. Lensvelt, MD, PhD, Clark J. Zeebregts, MD, PhD, Michel M.P.J. Reijnen, MD, PhD

Objective: Self-expanding covered stents for superficial femoral artery (SFA) occlusive disease have undergone an evolution during the years. Early results of the latest generation, the heparin-bonded Viabahn (W. L. Gore & Associates, Flagstaff, Ariz) with a contoured proximal edge, were promising, with reported 1-year primary patency rates of 73% to 78% in long lesions. The aim of this study was to present the 3-year outcome of the heparin-bonded Viabahn for SFA occlusive disease.
