Abstract: The lack of consistent definitions and nomenclature across clinical trials of novel devices, drugs, or biologics poses a significant barrier to accrual of knowledge in and across peripheral artery disease therapies and technologies. Recognizing this problem, the Peripheral Academic Research Consortium, together with the U.S. Food and Drug Administration and the Japanese Pharmaceuticals and Medical Devices Agency, has developed a series of pragmatic consensus definitions for patients being treated for peripheral artery disease affecting the lower extremities. These consensus definitions include the clinical presentation, anatomic depiction, interventional outcomes, surrogate imaging and physiological follow-up, and clinical outcomes of patients with lower-extremity peripheral artery disease. Consistent application of these definitions in clinical trials evaluating novel revascularization technologies should result in more efficient regulatory evaluation and best practice guidelines to inform clinical decisions in patients with lower extremity peripheral artery disease.
Objective: Patients with acute venous thromboembolism (VTE) are at increased risk for the development of subsequent arterial ischemic events unrelated to the diagnosis of VTE. Accurate identification of VTE patients at increased risk for ischemic events during the course of anticoagulation may help to select those who would potentially benefit from concomitant therapy with anticoagulants and antiplatelets.
Objective: The aim of this study was to monitor the changes that develop in leg veins of primigravida women during pregnancy.
Background: Venous reflux is the principal hemodynamic disorder and therapeutic target in patients with superficial venous insufficiency. To date, no studies have identified where or when it stops, anatomically or regionally, along the course of the refluxive conduit. Duplex measurements of reflux are performed invariably with a single probe. Because many anatomic locations are studied, repeated provocation maneuvers are required. However, this fails to appreciate reflux as a circulation. The use of two probes placed concurrently in different regions may address this limitation. The study compared venous reflux duration and cessation, above the knee and below the knee simultaneously, with two duplex probes
Background: Patients with femoral vein occlusion rapidly develop collateral flow through the deep femoral vein, an embryonic collateral. In contrast, iliac vein collateralization is sparser and functionally poorer. It is not uncommon to have femoral vein occlusions associated with iliac vein obstruction, even though the femoral vein occlusion is often more readily apparent on venograms and duplex scans, whereas the iliac vein obstruction may remain occult. We examined whether percutaneous stent correction of iliac vein obstruction associated with femoral vein occlusions would yield symptomatic relief.
Objective: The purpose of this study was to review preoperative and postoperative duplex scans and postoperative venograms in patients with subclavian vein thrombosis who underwent first rib resection and scalenectomy (FRRS) during 2005 to 2013.
Objective: The aim of this study was to assess the management and outcomes of arteriovenous malformations (AVMs) with a dominant outflow vein (DOV) treated with retrograde venous embolization.
Objective: Superficial venous reflux disease has been treated with endovenous ablation techniques for more than 15 years. Thrombi discovered in the postoperative period are referred to as endovenous heat-induced thrombi (EHIT). In spite of the few studies of the ultrasound differentiation between EHIT and deep vein thrombi (DVT), there remains a paucity of literature regarding the evaluation of ultrasound examination and pathologic differentiation.
Objective: Activation of proteolytic mechanisms at the cell surface through the activity of urokinase-type plasminogen activator (uPA) bound to its receptor, uPAR, is an important process in wound healing. The soluble forms of uPAR (suPAR and its fragments I, II, and III) have nonproteolytic functions that include chemotaxis, adhesion, and proliferation, which also have a role in wound healing. The aim of this study was to determine whether suPAR and its cleaved fragments are present in venous ulcers and whether their levels are associated with healing.
Objective: We conducted a systematic review of the literature about quality-of-life (QOL) scales in chronic venous disorders (CVDs) comprising leg ulcers to identify the respective advantages and deficits of existing tools.
Background: Inferior vena cava (IVC) filter placement is performed to mitigate the risk of pulmonary embolism (PE) when anticoagulation is contraindicated or ineffective. Technical advances now allow catheter-based filter retrieval. Many believe the benefits of retrieval are self-evident, yet retrieval carries an inherent complication risk and cost. The purpose of this study was to quantitatively weigh the risks and benefits of IVC filter retrieval using formal decision analysis.
Objective: Greater flexibility and smaller sizes for introducer sheaths in the newest stent grafts increase the feasibility of endovascular aneurysm repair but raise concerns about long-term limb patency. The aim of the study was to determine the incidence of and predictive factors for limb occlusion after use of the Endurant stent graft (Medtronic Inc, Minneapolis, Minn) for abdominal aortic aneurysm.
Objective: The objective of this study was to report long-term results of early endovascular aortic aneurysm repair after percutaneous coronary intervention (PCI).
Objective: Management of type II endoleaks after endovascular aneurysm repair can be problematic. This study reports our experience with a relatively novel strategy to treat this complication, transcaval coil embolization (TCCE) of the aneurysm sac.
