NCT ID: NCT05508581 Not yet recruiting - Varicose Veins Clinical Trials

Microwaves Ablation of Varicose Veins

Start date: October 15, 2023
Phase: N/A
Study type: Interventional

Lower-limb varicose veins (VVs) are the most common of vascular diseases and affect up to one-third of the population, severely affecting the quality of life (QoL) of patients. In past decades, traditional surgical ligation and stripping were the gold standard therapy for patients with VVs; however, traditional methods have demonstrated high complication and recurrence rates. Thus, the practices are moving toward minimally invasive alternatives.

NCT ID: NCT05500625 Not yet recruiting - Gastric Varix Clinical Trials

Endoscopic Ultrasound-guided Coil With Cyanoacrylate Injection Versus Balloon-Occluded Retrograde Transvenous Obliteration in Managing Patients With Gastric Varices

Start date: August 30, 2022
Phase: N/A
Study type: Interventional

Gastrointestinal bleeding is a common complication of liver cirrhosis which caused by esophageal and gastric varices. The risk of bleeding from gastric varices is relatively low. However, the bleeding is usually significant and severe. Current guidelines recommend endoscopic glue injection as the first line of treatment for gastric variceal bleeding. Although this technique has been shown to be effective, it is associated with many severe adverse events including systemic embolization, fever, chest pain, and even death. The rate of hemostasis has been reported to be as high as 91-100% but the rebleeding rate from gastric varices still present. Endoscopic ultrasound (EUS) guided therapy has recently been introduced as a more effective and safer option than endoscopic therapy for gastric varices. EUS-guided therapy includes EUS guided Cyanoacrylate injection alone or in combination with EUS-guided coiling. It offers the advantage of directly visualizing the varices and delivering targeted therapy. A standard endoscopic examination only allows the evaluation of superficial varices. The use of Endoscopic ultrasound facilitates evaluation of peri-gastric and perforating vessels, which are directly involved in variceal development. EUS also facilitates accurate placement of the coil and preserves the naturally formed splenorenal shunt. Balloon-occluded retrograde transvenous obliteration(BRTO) has been reported to achieve satisfactory bleeding control rates for isolated gastric varices with High hemostasis rates and low rebleeding rate. Despite all these promising results, there are scarce studies describing and comparing the efficacy of EUS-guided therapy and BRTO in patients with gastric varices. Further prospective comparative studies are needed.

NCT ID: NCT05380895 Not yet recruiting - Varicose Veins Clinical Trials

Comparison of Daytime Surgery in Varicose Veins Patients With and Without Superficial Venous Thrombosis

Start date: June 10, 2022
Phase:
Study type: Observational

Varicose veins of lower extremities are the most common disease in vascular surgery, and daytime surgery has gradually become the mainstream of varicose veins of lower extremities. Superficial venous thrombosis is one of the common complications of varicose veins of lower limbs. Current consensus is that patients with superficial venous thrombosis should be treated with standardized anticoagulant therapy to prevent their progression to venous thrombotic disease.SVT patients need standardized anticoagulant therapy for a period of time, while DS is current mainstream treatment of VV. Will the existence of SVT affect the safety and efficacy of DS of VV, leading a need of changing the treatment strategy and carrying out anticoagulant treatment for SVT before DS on VV patients? To date, there is no research on this issue. Therefore, we conducted this study to comprehensively evaluate the safety, feasibility, perioperative and long-term efficacy of DS in VV patients complicated with SVT, and systematically compared patients who had VV only.

NCT ID: NCT05342779 Not yet recruiting - Varicose Veins Clinical Trials

Radio Frequency Ablation Versus Stripping of Great Saphenous Vein in Management of Primary Varicose Veins , Comparative Study

Start date: June 2022
Phase: N/A
Study type: Interventional

Varicose veins are one of the most common diseases worldwide it constitutes a progressive disease which during its course it produces complications that usually prompt the patient to seek medical care. Epidemiological studies of the incidence and prevalence of varicose veins found that the majority of adults would develop it over the course of their lifetime; women were found to be four times likely as men to develop it, the incidence of varicose vein occurrence increases with age. Varicose veins are defined as tortuous dilated veins after or associated with incompetent valves.

NCT ID: NCT05199038 Not yet recruiting - Esophageal Varices Clinical Trials

Comparison of 2 Days Versus 5 Days of Octreotide After Endoscopic Therapy in Preventing Early Esophageal Varices Rebleed : A Randomized Controlled Study

Start date: June 2022
Phase: Phase 4
Study type: Interventional

The aim of this study is to compare the efficacy of 2-days versus 5-days octreotide infusion after endoscopic therapy in preventing early esophageal varices rebleed in patients with cirrhosis.

NCT ID: NCT04794712 Not yet recruiting - Clinical trials for Chronic Venous Insufficiency

Evaluation of Pain Associated With Chronic Venous Insufficiency

Start date: May 15, 2021
Phase:
Study type: Observational [Patient Registry]

Chronic venous insufficiency occurs when your leg veins don't allow blood to flow back up to your heart. Normally, the valves in your veins make sure that blood flows toward your heart. But when these valves don't work well, blood can also flow backwards. This can cause blood to collect (pool) in the legs. Chronic venous disease is a highly prevalent condition in the general population, and it has a significant impact on quality of life. While it is usually manifested by obvious signs, such as varicose veins and venous ulcers, other symptoms of the disease are less specific. Among the other symptoms, which include heaviness, swelling, muscle cramps and restless legs, pain is the symptom that most frequently compels CVeD patients to seek medical aid. However, there is a substantial discrepancy between pain severity and clinically detectable signs of CVeD, questioned by several opposing studies. Further evaluation is needed to clarify this subject, and to analyse whether pain development predicts objective tool to evaluate pain by dosflexin exercise pre surgery and post and measure the severity of pain by heat stimulation . General management of CVeD starts with advising lifestyle . pain in chronic venous insufficiency it will measure before and after treatment by using contact heat evoked potential (CHEPS) and visual dialog scale ( VAS ) to estimate the pain intensity the severity of the pain before the patient do exercise before three moths of leaser endovenous ablation procedure . 2-photo-plethysomography Non invasive technique , pp sensor emit infrared light detects changes in reflection from epiderma layer .

NCT ID: NCT04537052 Not yet recruiting - Clinical trials for Primary Varicose Veins

A New Method for Treatment of Deep Venous Insufficiency: Early Results of Vein Restoration Treatment(VRT)

Start date: September 27, 2020
Phase: N/A
Study type: Interventional

To present the 9. months clinical results of percutaneous Ven Restoration Therapy (VRT), a new method in the treatment of primary femoral vein insufficiency.Twenty four patients diagnosed with isolated primary femoral vein insufficiency between January 2020 and December 2020 were included in the study. Before the procedure, junctional femoral vein diameters and reflux times were measured. CEAP classification and Venous clinical severity scores (VCSS) were recorded. Chronic Venous Insufficiency Questionnaire (CIVIQ-20) were also recorded. Then, VRT was applied percutaneously to the anterior and posterior of the femoral veins of the patients, and the diameter of the femoral vein was narrowed and valve coaptation was achieved. After the procedure, vein diameters and reflux times were measured again. All parameters were reevaluated by calling patients for control at 1.,3., 6. and 9. months.

NCT ID: NCT04527666 Not yet recruiting - Clinical trials for Myeloproliferative Neoplasm

Anticoagulation in Gastroesophageal Varices and JAK2 Mutation

Start date: October 1, 2020
Phase:
Study type: Observational

Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. The aim of this study is to evaluate the efficacy of anticoagulation in patients with JAK2 mutation and gastroesophageal varices.

NCT ID: NCT04525768 Not yet recruiting - Portal Hypertension Clinical Trials

Gastroesophageal Varices in Cavernoma

Start date: October 1, 2020
Phase:
Study type: Observational

Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. Portal vein thrombosis and portal cavernoma frequently occur in the MPN population and the management of gastroesophageal varices in these patients are sometimes technically difficult. The aim of this study is to investigate the the characteristics of patients with gastroesophageal varices and portal caver cavernoma with or without JAK2 mutation.
