ENDOVASCULAR TODAY. Direct Ultrasound-Guided SFA Access

Christoph A. Binkert, MD, MBA, and Andreas Gutzeit, MD

For decades, the common femoral artery (CFA) has been considered the most appropriate arterial access site. The rationale has been that at the end of the procedure, the CFA can be compressed against the femoral head to achieve hemostasis. During standard access, the pulse is typically palpated, and the needle is advanced to the area of the strongest pulse. Although the intention is to access the CFA by palpation, in several cases, the superficial femoral artery (SFA), the deep femoral artery (DFA), or even the external iliac artery is accidentally punctured instead.

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS. Treatment of an iatrogenic femoral artery pseudoaneurysm with concomitant arteriovenous fistula with percutaneous implantation of an amplatzer vascular plug

Ranjith Shetty MD, Kapildeo Lotun MD

Iatrogenic pseudoaneurysms can occur following percutaneous cardiac and peripheral procedures. There are multiple modalities available for the treatment of pseudoaneurysms including ultrasound guided compression repair, ultrasound guided thrombin injection, or endovascular repair with covered stent placement. If these methods are not indicated or unsuccessful, patients typically require open surgical repair. We report a case of a woman with a post-procedural pseudoaneurysm with concomitant arteriovenous fistula who was treated percutaneously with the implantation of an Amplatzer vascular plug. This novel technique was safe and effective and allowed our patient to avoid the morbidity and mortality associated with surgical repair. © 2012 Wiley Periodicals, Inc.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Determinants of Early and Long-term Efficacy of Catheter-directed Thrombolysis in Proximal Deep Vein Thrombosis

Ylva Haig, MD, Tone Enden, MD, PhD, Carl-Erik Slagsvold, MD, PhD, Leiv Sandvik, MSc, PhD, Per Morten Sandset, MD, PhD, Nils Einar Kløw, MD, PhD

Purpose: Catheter-directed thrombolysis (CDT) for proximal deep vein thrombosis (DVT) effectively enhances clot removal and recently has been shown to reduce the development of postthrombotic syndrome (PTS). This study was performed to identify potential markers for early and long-term efficacy of CDT, adverse events, and their interrelationship.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Subintimal Angioplasty Track of the Superficial Femoral Artery. A Histological Analysi

Vincent P.W. Scholtes, MD, Gert Jan de Borst, MD, PhD, Jean-Paul P.M. de Vries, MD, PhD, Frans L. Moll, MD, PhD, Gerard Pasterkamp, MD, PhD, Maurice A.A.J. van den Bosch, MD, PhD and Aryan Vink, MD, PhD

Since it was first described in 1990, subintimal angioplasty (SIA) has proven to be a valuable alternative for bypass surgery in patients with atheroocclusive disease of the superficial femoral artery (SFA).1 In this minimally invasive technique, a guidewire is intentionally placed between the intima and the media to create a new track along the vessel wall, bypassing the atherosclerotic occlusion.2 However, to our knowledge, the exact route of this subintimal track has never been confirmed with histopathology.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. A Randomized, Controlled Pilot Study of Autologous CD34+ Cell Therapy for Critical Limb Ischemia

Wiechmann, MD, Charles Thompson, MD, Larry Kraiss, MD, Teresa Carman, MD, Suhail Dohad, MD, Paul Huang, MD, Candice E. Junge, PhD, Kenneth Story, MS, Tara Weistroffer, MS, Tina M. Thorne, MS, Meredith Millay, BS, John Paul Runyon, MD, Robert Schainfeld, DO

Background—Critical limb ischemia portends a risk of major amputation of 25% to 35% within 1 year of diagnosis. Preclinical studies provide evidence that intramuscular injection of autologous CD34+ cells improves limb perfusion and reduces amputation risk. In this randomized, double-blind, placebo-controlled pilot study, we evaluated the safety and efficacy of intramuscular injections of autologous CD34+ cells in subjects with moderate or high-risk critical limb ischemia, who were poor or noncandidates for surgical or percutaneous revascularization (ACT34-CLI).

CATHETERIZATION CARDIOVASCULAR INTERVENTIONS. The use of the trellis-6 thrombectomy device in the management of acute limb ischemia due to native vessel occlusion: Challenges, tips, and limitations

Brendan Daly MD, Mitul Patel MD, Anand Prasad MD, FACC, FSCAI

The role of endovascular therapy is expanding in the treatment of acute limb ischemia (ALI). In addition to catheter-based thrombolysis, there are multiple devices which allow for clot disruption and aspiration. The Trellis catheter system provides mechanical agitation of thrombus coupled with chemical thrombolysis. We present two cases of native arterial occlusions in which the Trellis catheter was used for thrombolysis. Procedural tips and challenges associated with the use of this device in native vessels are discussed. © 2012 Wiley Periodicals, Inc.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. The Quality and Impact of Risk Factor Control in Patients With Stable Claudication Presenting for Peripheral Vascular Interventions

Amer K. Ardati, MD, Samuel R. Kaufman, MA, Herbert D. Aronow, MD, MPH, Timothy J. Nypaver, MD, Paul G. Bove, MD, Hitinder S. Gurm, MD and P. Michael Grossman, MD

Background—Peripheral arterial disease is a manifestation of systemic atherosclerosis and is predictive of future cardiovascular events. Clinical trial data have demonstrated that medical therapy can attenuate cardiovascular morbidity and mortality in patients with peripheral arterial disease. The utilization and impact of recommended medical therapy in a contemporary population of patients who undergo percutaneous interventions for lifestyle-limiting peripheral arterial disease is unknown.

CVIR. Single-Center Experience and 1-Year Follow-up Results of “Sandwich Technique” in the Management of Common Iliac Artery Aneurysms During EVAR

Carmelo Ricci, Claudio Ceccherini, Marco Cini, Francesco Vigni, Sara Leonini, Giulio Tommasino, Luigi Muzzi, Enrico Tucci, Antonio Benvenuti, Eugenio Neri

Purpose: Abdominal aortic aneurysm (AAA) accompanied by common iliac artery (CIA) aneurysms requires a more demanding procedure owing to the difficulties in obtaining an adequate distal landing zone for the stent-graft limb(s), a potential site of endoleak. The “sandwich technique” is a procedure to increase EVAR feasibility in the setting of adverse or challenging CIA anatomy. Its main advantages include no restrictions in terms of CIA diameter or length or internal iliac artery (IIA) diameter, no need to wait for a specific stent-graft. Our purpose is to describe our single-center experience and one year follow-up results of this new procedure.
