NCT ID: NCT02676908 Recruiting - Varicose Veins Clinical Trials

Optimum Duration of Compression Stockings After Endovenous Varicose Vein Surgery

Start date: September 2016
Phase: N/A
Study type: Interventional

Compression stockings are traditionally worn for a period of time after varicose vein surgery to reduce pain and bruising. The investigators provide an ambulatory endovenous ablation service. Patients come to the Veins Unit, receive oral sedation, have their veins treated with either laser or radiofrequency ablation plus phlebectomies* under local anaesthetic, recover for an hour and then go home. *Phlebectomy describes the technique of pulling out small varicose veins through small incisions in the overlying skin. The standard practice of the Veins Unit is to advise patients to wear class two compression stockings for four weeks post-operatively. Many patients would prefer a shorter period of time in stockings. The Nice Guidelines for Varicose Veins has posed the question: 'How long should stockings be worn for after endovenous ablation?' Three trials have addressed this issue: Bakker looked at patients who wore stockings for either two or seven days after laser ablation only; the group who wore stockings for seven days fared better. Elderman looked at patients who either wore no stockings or stockings for two weeks after laser ablation only; the group who wore stockings for two weeks had less pain. Krasznai looked at patients who wore stockings for either 4 hours or 72 hours after radiofrequency ablation only; there was no significant difference in post-op pain among groups. None of these trials included patients who had phlebectomies at the same time. This study aims to answer the question 'How long is it necessary to wear compression stockings for after endovenous ablation (either laser or radiofrequency) plus concomitant phlebectomies?' The investigators plan to divide 110 patients into two groups- either 'stockings for 2 weeks' (trial group) or 'stockings for 4 weeks' (usual treatment group). Pre-operatively, all patients will fill out a pain score and two short quality of life questionnaires, one specific to varicose veins. Post-operatively at home, all patients will be asked to keep a diary of pain and analgesia use. They will also document bruising at seven days on charts and on a visual scale. At their four week clinic review, all patients will be asked to fill out a pain and bruising score, a bruising chart and the two short quality of life questionnaires again. The group with the best pain, bruising and quality of life scores post-operatively will help guide duration of compression therapy for future patients.

NCT ID: NCT02646202 Recruiting - Clinical trials for Gastroesophageal Varices

Scleroligation for Eradication of Gastroesophageal Varices.

Start date: January 2015
Phase: Phase 3
Study type: Interventional

Gastric varices occur in 5-33% of patients with portal hypertension. Concomitant gastro esophageal varices are the most common type. Both endoscopic sclerotherapy and band ligation are very effective in controlling acute esophageal varices bleeding and preventing rebleeding.

NCT ID: NCT02304146 Recruiting - Varicose Veins Clinical Trials

Long-term Ultrasound Guided Foam Sclerotherapy Versus Classical Surgical Stripping Study

Start date: November 2014
Phase: N/A
Study type: Observational [Patient Registry]

The aim of this study is to investigate the long-term follow-up of the previously conducted FOAM study.

NCT ID: NCT02139085 Recruiting - Varicose Veins Clinical Trials

Great Saphenous Vein Electrocoagulation

Start date: August 2014
Phase: Phase 2
Study type: Interventional

Introduction: Lower extremity Chronic Venous Insufficiency is a prevalent disease that adversely affects an individual's Quality of Life. Varicose vein endovenous radiofrequency treatment have a lower risk of iatrogenic injuries and offer faster return to work activities, when compared with open surgical techniques. Endovenous electrocoagulation can selectively and safely cause Great Saphenous Vein (GSV) wall necrosis but its clinical results has never been studied before. Objective: The objective of this study is to compare Great Saphenous Vein electrocoagulation and radio frequency (RF) endovascular varicose vein treatment clinical results and quality of life improvement in a prospective double blind randomized controlled clinical trial. Methods: Consecutive patients with varicose veins and primary GSV reflux will be randomized to Electrocoagulation or Radiofrequency endovenous treatment. The primary outcome measure will be GSV occlusion rate at 3 and 6 months after treatment verified by Duplex Scanning (DS). Secondary outcome measures will be pain visual analogue scale (VAS), bruising, neuropathy and vein thrombosis frequency in the immediate postoperative period (1 week); and Clinical Etiology Anatomy and Pathophysiology (CEAP) classification ,Venous Clinical Severity Scale (VCSS), and Aberdeen Varicose Vein Questionnaire (AVVQ), obtained preoperatively, at 3 and 6 months postoperatively. For statistical analysis, we will use the Student's t test, the Mann-Whitney test and Pearson's correlation, considering positive statistical significance when level of p <0.05.

NCT ID: NCT02115061 Recruiting - Gastric Varices Clinical Trials

Gastric Varices Treatment: Coil + Cyanoacrylate Versus Cyanoacrylate

Start date: August 2013
Phase: Phase 1
Study type: Interventional

The purpose of the spring is to maintain the cyanoacrylate polymer of the gastric varix, forming a conglomerate spring-cyanoacrylate, and thus preventing their migration to the adhesive embolism. The introduction of the spring is held by a echo-guided puncture. The window can be puncture through the distal esophagus or directly in the gastric varix via retroflexion to the fundus. Another advantage of this technique is its use in the presence of bleeding, when large amounts of blood in the stomach hinders the injection of the cyanoacrylate, by pricking the distal esophagus that difficulty decreases. The first study of this technique was performed by Binmoeller et al (21) and had good results with 100% hemostasis and low rebleeding rate (16%), but more studies are needed to prove the safety and efficacy of this technique.

NCT ID: NCT01287702 Recruiting - Varices Clinical Trials

Early Feeding Following Ligation of Acute Bleeding Varices

Start date: January 2011
Phase: Phase 4
Study type: Interventional

The impact of feeding after endoscopic treatment of gastroesophageal varices has never been investigated. It is still unknown whether early feeding may increase early rebleeding in patients with acute esophageal variceal bleeding treated with EVL. It is customary for clinicians to institute fasting for 2 or 3 days after emergency EVL. This may be a safe approach to watch against early rebleeding. However, many patients would be fasting for a longer time and nutrition may be impaired, possibly resulting in aggravation of ascites. Thus, the investigators conduct a controlled study to evaluate whether early feeding have a bad impact on patients receiving emergency EVL or histoacryl injection for bleeding gastric varices.

NCT ID: NCT00702897 Recruiting - Varicose Veins Clinical Trials

Ambulatory Surgery of Lower Extremity Varicose Vein

Start date: January 2008
Phase: N/A
Study type: Observational

OBJECTIVE: To retrospectively analyze the results of ambulatory treatment on Taiwanese patients with primary varicosities of the lower extremities including the use of endovenous laser, phlebectomy, and sclerotherapy. METHODS: We routinely used tumescent anesthesia and ultrasound-guided approaches for the application of endovenous laser. Vein access was achieved by either a percutaneous or stab wound. The laser power was usually 10 - 20 watts; laser treatment usually was begun from 4-10 cm below the saphenofemoral junction, and stopped around the knee, not over 10 cm below the knee. In the same operation, we used Mueller's phlebectomy and/or sclerotherapy if there were prominent branch varicosities. We instructed each patient to walk around immediately after the operation, to go home, and to come back 1-3 days later for follow-up. Ultrasound scan and venous function follow-up was scheduled at 1 month, 6 months, 12 months, and then annually.
