CATHETERIZATION & CARDIOVASCULAR INTERVENTIONS. Laser in infrapopliteal and popliteal stenosis 2 study (LIPS2): Long-term outcomes of laser-assisted balloon angioplasty versus balloon angioplasty for below knee peripheral arterial disease

Background: Laser-assisted balloon angioplasty (LABA) has been shown to be more effective in achieving angiographic success for treatment for below knee peripheral artery disease (PAD) compared with balloon angioplasty alone(BA). However, long-term outcomes of LABA compared with BA for popliteal and infrapopliteal PAD are unknown.

CATHETERIZATION & CARDIOVASCULAR INTERVENTIONS. Endovascular revascularization of a surgically ligated superficial femoral artery: A case report

Kalkidan Bishu MD, MS1,2 andEhrin J. Armstrong MD, MSC, MAS1,2,*

We present a case of a patient with left lower extremity ischemic rest pain who initially underwent surgical profundaplasty requiring ligation of his superficial femoral artery (SFA). The patient developed continued rest pain due to diffuse disease of his profunda and inadequate collaterals. Endovascular intervention was therefore performed to the oversewn SFA. Retrograde left SFA access was obtained and the origin of the SFA was recanalized with true lumen re-entry using an ultrasound guided re-entry catheter. Angioplasty was performed at the origin of the SFA and self-expanding stents were deployed in the proximal and mid left SFA. Hemostasis at the distal left SFA access site was obtained by balloon inflation at the access site and manual compression. This case illustrates the feasibility of endovascular repair of a ligated SFA. © 2015 Wiley Periodicals, Inc.

Background: Current practice guidelines recommend surgical repair of large thoracic aortic aneurysms to prevent fatal aortic dissection or rupture, but limited natural history data exist to support clinical criteria for timely intervention.

CATHETERIZATION & CARDIOVASCULAR INTERVENTIONS. The use of the AVERT system to limit contrast volume administration during peripheral angiography and intervention

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.
