REVIEW
Jos C van den Berg
The endovascular treatment of atherosclerotic disease of the infra-inguinal arteries has changed significantly over the last decades. In an attempt to overcome the high restenosis rates that characterize plain balloon angioplasty and stenting using bare mate stents drug-eluting balloon technology has been applied in the treatment of lesions of the superficial femoral and popliteal artery. This paper will give an overview of the rationale and the technology of drug-eluting balloons and will review currently available data from registries and randomized controlled trials...

OBJECTIVE: The radial artery is often used for coronary angiography, with a demonstrated decrease in local complications and an increase in postoperative mobility of the patient. Data on radial artery access for peripheral endovascular procedures, however, are limited. We describe our experience with radial artery access for diagnostic and endovascular interventions. METHODS: Between February 2012 and March 2015, there were 95 endovascular procedures performed using radial artery access in 80 unique patients...

Distal embolization is a common occurrence with peripheral arterial interventions and is more frequent with the use of atherectomy devices. We report the first case of JetStream atherectomy (Boston Scientific, Maple Grove, MN) with the use of the novel WIRION embolic protection system filter. The procedure was performed successfully with no distal embolizations beyond the filter and with no complications in the delivery or retrieval of the filter. The pros and cons of the off label use of this filter with JetStream atherectomy are discussed...

We present here the improved design and development of optical sensor for non-invasive measurements of arterial blood flow waveform. The sensor is based on a physical principle of reflective photoplethysmography (PPG). As the light source we used serially connected infrared diodes whereas NPN silicon phototransistors were used as light detectors. The electronic components were molded into square package and poured with silicone. Such preparation produced an elastic superficies that allowed excellent attachment of the sensor on the skin's surface...

Local drug delivery of an anti-proliferative drug from balloon catheter systems to the site of arterial injury has been attempted repeatedly over the years with limited success in drug uptake and retention. Accessibility of the drug at the site is critical to combat the body's response to the procedural trauma of angioplasty. Recently, formulations have been designed which achieve delivery of therapeutic doses of the anti-proliferative drug paclitaxel to arteries with higher efficiency and longer tissue retention...

This analysis compared the angiographic outcomes of patients treated with orbital atherectomy for calcified common femoral artery (CFA) and superficial femoral artery (SFA) disease. The ideal revascularization strategy for CFA disease is unknown. Endarterectomy has been considered the standard of care for CFA disease for over 50 years. Endovascular intervention is becoming more commonly used to revascularize the CFA given the advances in technology and the less invasive nature of the procedure. Patient demographics, lesion characteristics, and procedure data for all CONFIRM patients with at least one CFA lesion location ( n=147 patients; n=200 lesions) were compared to patients with at least one SFA lesion location ( n=1508 patients; n=2367 lesions)...

INTRODUCTION: Deep wound infections in the groin region can result in an acute or life threatening condition. Especially when there is no suitable vein available because of many reasons (e.g. previous surgery, small vessel diameter). Synthetic prosthesis sometimes are not 'first-choice-technique' because of contamination or infection. It was ad hoc hypothesized in an acute setting that a segment of an occluded Superficial Femoral Artery (SFA) could be used as a conduit in combination with eversion technique, known from carotid surgery...

BACKGROUND: High failure rates of femoropopliteal artery (FPA) interventions are often attributed in part to severe mechanical deformations that occur with limb movement. Axial compression and bending of the FPA likely play significant roles in FPA disease development and reconstruction failure, but these deformations are poorly characterized. The goal of this study was to quantify axial compression and bending of human FPAs that are placed in positions commonly assumed during the normal course of daily activities...

BACKGROUND: Severe limb ischaemia (SLI) is defined as the presence of rest pain and/or tissue loss secondary to lower extremity atherosclerotic peripheral arterial disease. The superficial femoral and popliteal arteries are the most commonly diseased vessels in such patients and are being increasingly treated using endovascular revascularisation techniques. However, it is currently unknown whether drug-eluting stents and drug-coated balloons confer additional clinical benefits over more established techniques using plain balloons and bare metal stents, or whether they represent a cost-effective use of NHS resources...

There are three less frequent manifestations of acute massive venous thrombosis and obstruction of the venous drainage of an extremity. They are phlegmasia alba dolens, phlegmasia cerulean dolens (PCD), and venous gangrene. The term PCD differentiates ischemia-associated massive venous thrombosis from phlegmasia alba dolens, which describes fulminant venous thrombosis without ischemia. We present a 55-year-old hypertensive, who presented with paedal oedema and breathlessness at rest. About a month prior to this admission, she suffered dislocation of left patella...

OBJECTIVE: In patients lacking autogenous vein suitable for infrainguinal bypass, cryopreserved saphenous vein (CSV) allograft (CryoLife, Inc, Kennesaw, Ga) may be an acceptable alternative. The purpose of this study was to examine outcomes of CSV conduit for infrainguinal revascularization. METHODS: Between February 2008 and August 2015, 70 patients underwent infrainguinal bypass grafts in 73 limbs using CSV. All patients lacked suitable arm or leg vein. Demographic data and patient outcomes were retrospectively collected using electronic medical records...

BACKGROUND: The role of collateral artery circulation in the lower limb is under debate but clinically relevant, particularly when using covered stents for occlusive disease. Covered stents seem to outperform nitinol stents in extensive disease, but collaterals could be essential in case of acute thrombosis. In the present study, we describe the collateral pathways of the deep and superficial femoral artery (DFA, SFA) and the popliteal artery (PA), observed in human cadavers. METHODS: Ten fresh frozen cadaver legs were selected...

A 96-year-old male presented with left lower extremity pain, swelling, and vascular compromise. Computed tomographic angiography revealed an actively rupturing distal superficial femoral artery aneurysm. The patient underwent prompt aneurysm excision with graft interposition and had a successful postoperative outcome. Our case illustrates the critical role of imaging in establishing a definitive diagnosis and preventing mortality.

BACKGROUND: A polymer-free peripheral paclitaxel-eluting stent (PES, Zilver PTX, Cook, IN) has shown to improve vessel patency after superficial femoral angioplasty. A new-generation fluoropolymer-based PES (FP-PES; Eluvia, Boston Scientific, MA) displaying more controlled and sustained paclitaxel delivery promise to improve the clinical outcomes of first-generation PES. We sought to compare the biological effect of paclitaxel delivered by 2 different stent-coating technologies (fluoropolymer-based versus polymer-free) on neointimal proliferation and healing response in the familial hypercholesterolemic swine model of femoral restenosis...
