OBJECTIVES: Endovenous thermal ablation (EVTA) of varicose veins was introduced in the late 1990s with radiofrequency ablation (RFA) using the VNUS Closure device. The results of the original VNUS Closure device for the abolition of truncal venous reflux at 15 years are reported. METHODS: A prospective audit of a group of patients treated with VNUS Closure 15 years previously was carried out, using clinical assessment and duplex ultrasound. A total of 189 patients were treated with VNUS Closure between March 1999 and December 2001 and were invited for clinical assessment (subjective and objective) and duplex ultrasonography (DUS) to assess treatment outcome and de novo disease progression...

BACKGROUND: Intervention on the great saphenous vein (GSV) has traditionally been limited to the above-knee (AK-GSV) segment for fear of saphenous neuralgia in spite of incompetence demonstrated in the below-knee (BK-GSV) segment. Residual symptoms and need for reintervention are reported to result in nearly half the patients if the refluxing BK-GSV is ignored. Experience with endovenous ablation of the BK-GSV at the time of AK-GSV treatment is sparsely reported in the literature. The aim of this study was to evaluate the safety of endovenous ablation of the refluxing BK-GSV...

BACKGROUND: Endovenous ablation (EVA) of the great saphenous vein (GSV), with radiofrequency (RFA) or laser ablation (EVLA), has largely replaced the standard ligation and stripping (L&S). Several randomized controlled trials (RCTs) have reported data on efficacy of the ablation with little focus on complications. We analyzed the current literature for short-term complications of EVA as compared with L&S. METHODS: We searched MEDLINE, the Cochrane Central Trials Registry, and individual journals from January 2008 through January 8, 2013 for RCTs comparing RFA and/or EVLA and/or L&S to treat GSV incompetence...

OBJECTIVE: Cerebrovascular events have been noted after foam sclerotherapy for varicose veins. One hypothesis is migration of microemboli to the brain through a cardiac septal defect. The aim of this study was to identify whether acoustic reflectors are found in the right side of the heart during radiofrequency ablation of varicose veins, as neurological events are not reported during these procedures. METHODS: Transthoracic echocardiography was performed during local anaesthetic radiofrequency ablation (VNUS ClosureFast) of the great saphenous vein in 14 patients...

Until recent years, the gold standard for treatment of truncal varicose veins has been high ligation and stripping of the saphenous vein. In the course of the last decade, new minimally invasive techniques based on endothermal ablation are progressively supplanting conventional surgery in the treatment of varicose veins. The endovenous treatment of varicose veins has been developed to reduce complications associated with conventional surgery and to improve quality of life. Radio frequency ablation (RFA) available since 1999 is now established as a safe and efficacious treatment for the ablation of refluxing saphenous veins...

BACKGROUND: Endovenous ablation of varicose veins using radiofrequency ablation (RFA) and endovenous laser therapy (EVLT) has reported advantages over traditional open surgical treatment. There is little evidence comparing the efficacy and patient-reported outcomes between the 2 endovenous solutions. This study compares the RFA and EVLT strategies in a prospective double-blind clinical trial. METHODS: Consecutive patients with primary unilateral great saphenous vein (GSV) reflux undergoing endovenous treatment were randomized to RFA (VNUS ClosureFAST) or EVLT (810-nm diode laser)...

UNLABELLED: Lower limb varicose veins are often secondary to greater saphenous vein (GSV) insufficiency. Technological development has led to the appearance of new minimally invasive treatments, such as endovenous radiofrequency ablation (ERFA). This almost completely eliminates the disadvantages associated with conventional surgery (haematomas, scars, inguinal neovascularisation, and a prolonged time off work). Furthermore, it gives a better quality of life, less pain and inflammation than the endolaser...

The SFV Expression System is a DNA expression system used to produce recombinant protein in eukaryotic cells (1,2). The SFV system is based on the Semliki Forest Vnus (SFV), which has several features that provide distinct advantages for a good cDNA expression system. These are: 1. The SFV RNA genome has a positive polarity and thus functions directly as an mRNA. Infectious RNA molecules can be therefore obtained by transcription from a full-length cDNA copy of the genome, 2. The SFV RNA molecule codes for its own RNA rephcase...

The hepatitis C virus (HCV) is an orgainsm of the age of molecular biology, for its discovery and much of the research into the infection have relied heavily on molecular techniques. The development of molecular cloning enabled a successful strategy that finally identified HCV (1)as the cause of 90% of posttransfusion (2)and > 50% of sporadic non-A, non-B hepatitis (3) after the failure by immunological techniques to discover the responsible agent. It is an important infection as most infected patients developed chronic hepatitis (> 50%) that can progress to cirrhosis and hepatocellular carcinoma (4-6) ...
