PURPOSE: Primary arteriovenous fistula arterio venous fistula (AVF) formation has proven to be the best and optimal vascular access for the majority of haemodialysis patients. At present there are limited data to suggest which haemodynamic parameters most correlate with the likelihood of early failure. The aim of this study is to identify the haemodynamic predictors of early failure, hence identify which fistulae may benefit from timely pre-emptive intervention. MATERIAL AND METHODS: Retrospective analysis of data was performed of 201 patients undergoing native AVF creation over a one year period...

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...

Venous diseases are highly prevalent, mostly caused by valve incompetence and/or obstruction of the vein lumen. Signs and symptoms are diverse and unspecific. Careful clinical assessment and imaging interpretation are crucial to diagnosis. Duplex ultrasound is the first choice and often the gold standard imaging technique for this purpose, providing information on the anatomy and function of the veins. This article describes the sonographic anatomic and hemodynamic criteria used for the diagnosis of venous reflux, venous obstruction, and the most frequent complications after interventions in the superficial, perforating, and deep venous systems...

BACKGROUND: The D-Dimer (DD) level combined with the pretest Wells criteria probability (WCP) score can safely exclude Deep Venous Thrombosis (DVT). The objective for this study was to examine the correlation between DD results alongside WCP score with findings on venous duplex ultrasound (VDU). The hypothesis is that VDU remains over utilized in low-risk patients with negative DD and that higher DD levels may correlate with thrombus burden and location. METHODS: Patients who presented to a high volume tertiary care center with lower limb swelling with or without associated pain were retrospectively examined through June and July for four consecutive years (2012 to 2015)...

OBJECTIVE: Chronic venous insufficiency (CVI) affects 25 million adults in the United States. Little emphasis has been placed on inflammatory changes associated with CVI. We hypothesize that in patients with early to mid-stage benign varicose vein disease, differences in circulating inflammatory mediators will be manifested in blood draining the involved area vs circulating blood in control subjects. METHODS: Patients undergoing either endovenous ablation or sclerotherapy for Clinical, Etiology, Anatomy, and Pathophysiology clinical class 3 to 5 disease underwent phlebotomy from regional veins at the time of the procedure...

Background Patients with post-thrombotic syndrome due to chronic venous obstruction and resistant to conservative management can benefit from endovenous revascularization. The current study investigated the usefulness of duplex ultrasound in monitoring the stent changes over the time. Method All duplex ultrasound images of treated patients were reviewed retrospectively. The stent diameter and area during the follow-up visits have been analyzed. Result A total of 210 stents were placed in 137 limbs. Duplex ultrasound findings showed a decrease in area of stent in all patients (mean: 0...

Deep venous thrombosis (DVT) is a significant medical problem with an incidence of 1 in 1,000 adults and greatly reduces quality of life through post-thrombotic syndrome. Treatment choice for DVT can be influenced by the age of the clot. While new endovascular catheter techniques treat venous clots to potentially prevent post-thrombotic syndrome, they require improved imaging techniques to accurately determine clot age. This review investigates experimental and clinical evidence of elastography techniques for aging DVT...

OBJECTIVE: No standardized therapeutic algorithm or embolic agent of choice has yet been identified for management of congenital peripheral venous malformations (VMs). Treatment options and reported outcomes therefore vary widely. Herein, we present an institution-wide algorithm for management of symptomatic congenital peripheral VMs using a single embolotherapeutic modality. METHODS: During 36 months, patients with symptomatic congenital peripheral VMs underwent contrast-enhanced magnetic resonance imaging...

OBJECTIVE: Minimally invasive interventions by recanalization, percutaneous transluminal angioplasty, and stenting in post-thrombotic syndrome (PTS) obstructions and iliac vein compression syndrome (IVCS) have shown good results. Until recently, no dedicated venous stents were available, and stent-related issues accounted for a decrease in patency scores. The introduction of dedicated stents with more flexibility and higher radial forces could result in higher patency scores. This study focused on the outcomes of patients treated by a dedicated sinus-Venous stent (OptiMed GmbH, Ettlingen, Germany)...

Upper extremity deep vein thrombosis (UEDVT) is defined as thrombosis of the deep venous system (subclavian, axillary, brachial, ulnar, and radial veins), which drains the upper extremities. It can be caused by thoracic outlet anatomic obstruction, such as Paget-Schroetter syndrome, (primary) or by central intravenous catheters (secondary). UEDVT may be asymptomatic or present with acute severe pain and arm swelling. Clinical suspicion should be confirmed by diagnostic imaging procedures such as duplex ultrasound, computed tomography scan, or magnetic resonance imaging...

A young male underwent decompressive craniotomy for an intracerebral bleed. A right-sided subclavian central venous catheter was placed in the operating room after induction of anesthesia. Postoperatively, he was shifted to Intensive Care Unit (ICU) for mechanical ventilation due to low Glasgow coma scale. He had an episode of severe agitation and straining on the tracheal tube in the evening same day. On the 2nd postoperative day in ICU, his airway pressures were high, and chest X-ray revealed massive pleural effusion on right side...

OBJECTIVE: Endovenous thermal ablation has become the primary modality of treatment for patients with venous insufficiency. Previous literature has provided reviews of radiofrequency ablation (RFA) or endovenous laser ablation (EVLA) that mostly focus on the great saphenous vein (GSV) and small saphenous vein (SSV). Data with an extended review including the anterior accessory saphenous vein (ASV) and perforator veins (PVs) have been limited. This study examines the treatment of venous insufficiency with RFA and EVLA of these multiple veins to identify clinical and demographic predictors of both the early success and thrombotic complications of endovenous thermal ablation...

Venous insufficiency of the lower limb is a common disease. Diagnosis is based on symptoms, clinical findings and duplex ultrasound. Consideration and planning of invasive treatment cannot be performed without ultrasound. Vast majority of invasive treatments in superficial venous insufficiency can be done by ultrasound-guided endovenous methods with local anesthesia. Thermoablation (laser of radiofrequency) is the first-line treatment. There are promisisng endovenous methods for treatment of deep venous obstruction in selected cases...
