JOURNAL OF VASCULAR SURGERY. Ambulatory percutaneous endovascular abdominal aortic aneurysm repair

Hasan H. Dosluoglu, MD , Purandath Lall, MBBS , Raphael Blochle, MD , Linda M. Harris, MD , Maciej L. Dryjski, MD

Objective: Percutaneous endovascular abdominal aortic aneurysm repair (PEVAR) has been associated with fewer groin wound complications and shorter operative times, but same-day discharge (SDD) has not been reported. The goal of our article is to assess the feasibility and safety of ambulatory PEVAR and identify patient characteristics that are eligible for this approach.

DIAGNOSTIC AND INTERVENTIONAL RADIOLOGY. The effect of laser wavelength on postoperative pain score in the endovenous ablation of saphenous vein insufficiency

Enes Duman, Erkan Yıldırım, Tonguç Saba, Mehmet Özülkü, Murat Günday, Gökçen Çoban

PURPOSE: Endovenous laser ablation has replaced surgical methods in the treatment of saphenous insufficiency. The aims of this study were to compare the effectiveness of 1470- and 980-nm wavelength (WL) laser systems, to compare the postoperative complication rates, and to determine the effect of laser WL on postoperative pain scores.

STROKE. Multicenter Experience on Eversion Versus Conventional Carotid Endarterectomy in Symptomatic Carotid Artery Stenosis. Observations From the Stent-Protected Angioplasty versus Carotid Endarterectomy (SPACE-1) Trial

Serdar Demirel, MD; Nicolas Attigah, MD; Hans Bruijnen, MD; Peter Ringleb, PhD; Hans-Henning Eckstein, PhD; Gustav Fraedrich, PhD; Dittmar Böckler, PhD on behalf of the SPACE Investigators

Background and Purpose—Carotid endarterectomy (CEA) is beneficial in patients with symptomatic carotid artery stenosis. However, randomized trials have not provided evidence concerning the optimal CEA technique, conventional or eversion.

CIRCULATION. Early Results of Fenestrated Endovascular Repair of Juxtarenal Aortic Aneurysms in the United Kingdom

On behalf of the British Society for Endovascular Therapy and the Global Collaborators on Advanced Stent-Graft Techniques for Aneurysm Repair (GLOBALSTAR) Registry

Background—Fenestrated endovascular repair of abdominal aortic aneurysms has been proposed as an alternative to open surgery for juxtarenal and pararenal abdominal aortic aneurysms. At present, the evidence base for this procedure is predominantly limited to single-center or single-operator series. The aim of this study was to present nationwide early results of fenestrated endovascular repair in the United Kingdom.

JACC. Oxidation-Specific Biomarkers and Risk of Peripheral Artery Disease

Monica L. Bertoia, MPH, PhD; Jennifer K. Pai, MHS, ScD; Jun-Hee Lee, MD, PhD; Adam Taleb, MD; Michel M. Joosten, PhD; Murray A. Mittleman, MD, DrPH; Xiaohong Yang, BS; Joseph L. Witztum, MD; Eric B. Rimm, ScD; Sotirios Tsimikas, MD; Kenneth J. Mukamal, MD, MPH

Objectives: The goal of this study was to examine the prospective association between oxidation-specific biomarkers, primarily oxidized phospholipids (OxPL) on apolipoprotein B-100–containing lipoproteins (OxPL/apoB) and lipoprotein (a) [Lp(a)], and risk of peripheral artery disease (PAD). We examined, as secondary analyses, indirect measures of oxidized lipoproteins, including autoantibodies to malondialdehyde-modified low-density lipoprotein (MDA-LDL) and apolipoprotein B-100 immune complexes (ApoB-IC).

ENDOVASCULAR TODAY. Applying Atherectomy in CLI Patients

By Thomas Zeller, MD, and Lawrence A. Garcia, MD

Critical limb ischemia (CLI) is the most advanced manifestation of peripheral arterial disease and is characterized by persistently recurring rest pain requiring regular analgesia and/or nonhealing ulceration or gangrene of the foot or toes due to impaired blood flow to such an extent that the nutritive requirements of the tissues cannot be met. CLI is generally characterized by multilevel arterial occlusive disease or extensive below-the-knee (BTK) artery involvement and is associated with a high risk for limb and/or tissue loss.1-3

ENDOVASCULAR TODAY. Guidewire Selection for Peripheral Vascular Interventions

By Craig Walker, MD

Guidewires are an integral part of vascular intervention. They are utilized to access target vessels, cross lesions, and deliver definitive interventional therapy. There are many choices in guidewires, as different clinical presentations require different device attributes (Figure 1). Selection of an appropriate guidewire can improve crossing success (particularly in total occlusions), improve device delivery, limit cost, and limit the risk of vascular injury either from the distal wire tip or wire shaft buckling.

ENDOVASCULAR TODAY. Options for Chronic Total Occlusions

By Thomas P. Davis, MD, and James Torey, PA-C

The treatment of chronic total occlusions (CTO) is challenging for the endovascular specialist. Historically, long total occlusions were treated with bypass surgery. Patients with significant comorbidities, however, increasingly need more aggressive percutaneous treatment options. Standard guidewire techniques have been the most frequently used for crossing total occlusions. Treatment failures occur about 20% to 25% of the time;1 the most common reason is failure to cross back into the true lumen beyond the distal cap. Crossing technologies were developed to assist in the treatment of difficult lesions and to increase success rates. Patients with critical limb ischemia depend on successful revascularization, thus making these devices potentially limb saving.

ENDOVASCULAR TODAY. Technique: Ultrasound Guidance for Lower Extremity Interventions

By Jihad A. Mustapha, MD; Matthew Sevensma, DO; Larry J. Diaz-Sandoval, MD; and Fadi Saab, MD

As tibial arterial intervention is becoming more prevalent, noninvasive imaging modalities can increasingly assist endovascular revascularization. Arterial duplex ultrasonography has become an integral part of tibial vessel endovascular interventions in our laboratory. Many procedures are scheduled with an ultrasound technologist present to assist the endovascular specialist in achieving access and delivering therapy.
