OBJECTIVE. The purpose of this article is to study the incidence, risk factors, and treatment of gross hemoglobinuria and oliguria following sclerotherapy for venous malformations.
Background—In disease of the femoropopliteal artery, paclitaxel-coated balloon (PCB) therapy improved angiographic outcomes as compared with uncoated balloon (UCB) angioplasty. Nevertheless, it remains uncertain whether PCB may reduce the need for reintervention.
Objectives The study investigated the long-term clinical impact of sirolimus-eluting stents (SES) in comparison with bare-metal stents (BMS) in treatment of focal infrapopliteal lesions.
Objectives This study sought to identify incidence, predictors, and impact of vascular complications (VC) after transfemoral (TF) transcatheter aortic valve replacement (TAVR).
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.
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.
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.
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).
Objectives: This study aimed to assess the clinical implications and optimal cutoff value of high platelet reactivity (HPR) in patients receiving clopidogrel for peripheral endovascular procedures.
Objectives: A prospective, multinational randomized controlled trial (RCT) and a complementary single-arm study evaluated the 2-year safety and effectiveness of a paclitaxel-coated drug-eluting stent (DES) in patients with superficial femoral artery lesions. The RCT compared the DES with percutaneous transluminal angioplasty (PTA) and provisional bare-metal stent (BMS) placement.
Background—Patent false lumen in aortic dissection has been associated with poor prognosis. We aimed to assess the natural evolution of this condition and predictive factors.
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
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.
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.
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.
