Background Venous disease is the most common cause of leg ulceration. Although compression therapy improves venous ulcer healing, it does not treat the underlying causes of venous hypertension. Treatment of superficial venous reflux has been shown to reduce the rate of ulcer recurrence, but the effect of early endovenous ablation of superficial venous reflux on ulcer healing remains unclear. Methods In a trial conducted at 20 centers in the United Kingdom, we randomly assigned 450 patients with venous leg ulcers to receive compression therapy and undergo early endovenous ablation of superficial venous reflux within 2 weeks after randomization (early-intervention group) or to receive compression therapy alone, with consideration of endovenous ablation deferred until after the ulcer was healed or until 6 months after randomization if the ulcer was unhealed (deferred-intervention group)...

OBJECTIVE: Radiofrequency ablation (RFA) is increasingly being employed for treatment of perforator vein insufficiency and venous ulcer healing. Previous studies have shown a closure rate of 60% to 80% in incompetent perforator veins (IPVs) with RFA. The purpose of the study was to determine the utility of a redo RFA for symptomatic recanalized perforators and to predict factors associated with recanalization. METHODS: A retrospective analysis of 642 procedures in 256 patients with venous insufficiency due to IPVs from 2009 to 2015 was conducted...

The number and complexity of endovascular procedures performed via either arterial or venous access are steadily increasing. Albeit associated with higher morbidity compared to the radial approach, the traditional common femoral artery remains the preferred access site in a variety of cardiac, aortic, oncologic and peripheral vascular procedures. Both transarterial and venous cannulation (for electrophysiology, intravenous laser ablation and central catheterisation) at the groin may result in potentially severe vascular access site complications (VASC)...

Platelet degranulation is crucial for hemostasis and may participate in inflammation. Exocytosis in platelets is mediated by SNARE proteins and should be controlled by Munc13 proteins. We found that platelets express Munc13-2 and -4. We assessed platelet granule exocytosis in Munc13-2 and -4 global and conditional KO mice, and observed that deletion of Munc13-4 ablates dense granule release and indirectly impairs alpha granule exocytosis. We found no exocytic role for Munc13-2 in platelets, not even in the absence of Munc13-4...

BACKGROUND: Four nonvitamin K antagonist oral anticoagulants (NOACs) have been approved for use in various cardiovascular indications. The direct thrombin inhibitor dabigatran and the direct factor Xa inhibitors apixaban, edoxaban, and rivaroxaban are now increasingly used in clinical practice. For some of these agents, available data from real-world studies support the efficacy and safety data in phase III clinical trials. OBJECTIVES: This review aims to summarize the current status of trials and observational studies of oral anticoagulant use over the spectrum of cardiovascular disorders (excluding venous thrombosis), provide a reference source beyond stroke prevention for atrial fibrillation (AF) and examine the potential for novel applications in the cardiovascular field...

Bolus timing is critical to optimal magnetic resonance angiography (MRA) acquisitions but can be challenging in some patients. Our purpose was to evaluate whether contrast-enhanced time-resolved magnetic resonance angiography (TR-MRA), a dynamic multiphase sequence that does not rely on bolus timing, is a viable alternative method to conventional 3D fast-long angle shot contrast-enhanced magnetic resonance angiography (CE-MRA). Coronal subtracted conventional CE-MRA images in 50 consecutive patients presenting for pre-atrial fibrillation ablation pulmonary venous (PV) mapping were compared with 50 TR-MRA images performed in 50 subsequent patients...

REVIEW
Misaki M Kiguchi, Ellen D Dillavou
Open saphenous removal, phlebectomy, and venous ligation were historic mainstays of surgical treatment of venous disease. Duplex ultrasound has become standard to diagnose venous insufficiency. Percutaneous modalities have allowed treatments to include thermal and nonthermal endovenous ablation. These treatments vary in preoperative planning, procedural steps, and postprocedural care, but all are safe and effective. An individualized approach should be taken in determining which modality is offered to each patient...

Background There have been well-documented implications of race/ethnicity on the outcome of various vascular diseases, yet there are limited data on risk factors and outcome of lower limb swelling. While many patients improve with endovenous therapy (thermal ablation or iliac vein stenting), some patients' symptoms persist. The goal of this study was to identify clinical factors including race/ethnicity related to persistent leg swelling after treatment with both iliac vein stenting and thermal ablation. Methods From February 2012 to February 2014, this observational study analyzed data for 173 patients with chronic venous insufficiency who underwent both iliac vein stent placement as well as thermal ablation (radiofrequency ablation or endovenous laser ablation)...
