Filter by:The purpose of this study is to evaluate whether adding sulodexide to the patients with varicose veins who received radiofrequency ablation combined with sclerotherapy can reduce or improve the impact of adverse events。
The purpose of this study is to assess the impact of immersive soundscape on patient pain, stress, anxiety, heart rate and blood pressure during an outpatient vascular surgery procedure.
The National Varicose Vein Study is a cross-sectional, multicenter, observational study. The primary goal is to evaluate the 30 days outcome of the conventional great saphenous vein surgery (stripping) in the treatment of the symptomatic chronic venous insufficiency, comparing the results of difference Portuguese's health centers, comparing the following variables: thrombo-prophylaxis (pharmacology or mechanic; compliance); antimicrobial prophylaxis; quality of life; medication compliance; complications and work incapacity period.
The goal of this exploratory validation study is to compare levels of expertise (or non-expertise) between GI fellows and experts with the varix trainer. The main question it aim to answer is: Can the varix trainer distinguish levels of expertise (or non-expertise) between novices and experts for specific skills (torque, small wheel and retroflexion techniques)? Does the training with the varix trainer improves these specific skills of GI fellows? Participants will do the pre-training test, practicing eight-sessions (each session is approximately 15minutes) and then do the post-training test.
VelexTM Venous Catheter is a venous catheter for temporary use to treat a vein isolated segment, designed for the treatment of varicose veins of lower limbs by means of chemical ablation or empty-vein sclerotherapy. V.A.S.C. is a multicentric, prospective, open label, non-randomized PMCF study of VelexTM venous catheter used according to the indication of use within the scope of the CE mark. VelexTM venous catheter is intended for patients with varicose veins of lower limbs. The total minimum number of patients is 24 and the maximum 36 for the two centers participating. Each center shall enroll at least 8 patients andno more than 28.
This study aimed to clarify the safety of anticoagulant therapy after glue injection for cirrhotic variceal bleeding patients with portal vein thrombosis.
Patients meet Baveno VI criteria (with a liver stiffness <20kPa and with a platelet count >150,000 are considered to have very low risk of having varices requiring treatment, but whether these patients can be followed up by repetition of this criteria lacks sufficient evidence. This study aimed to assess the value of Baveno VI criteria for following up and monitoring of varices needing treatment in patients with compensated cirrhosis.
The purpose of the study is to determine the clinical impact of cyanoacrylate tissue adhesive treatment for Gastric Varices performed by Indiana University EUS physicians.
Varicose veins of lower extremities can lead to adverse consequences such as ulceration and hemorrhage, which seriously endangering the physical and mental health and quality of life for patients. The aim of this study is to explore the potential risk factors of venous ulceration in patients with varicose veins of lower extremities based on a case-control study, and to provide a reference for personalized treatment.
The aim of this study is to explore whether using endoscopic ultrasound (EUS) to assess gastric varices (GV) and giving additional treatment according to the diameter and blood flow of residual after endoscopic cyanoacrylate injection for GV can reduce the rate of GV rebleeding, mortality, the risk of adverse events, and cost-effectiveness. This study is a multicenter prospective, open-label, randomized controlled study, including 5 study centers: Renmin Hospital of Wuhan University, Beijing Friendship Hospital, Capital Medical University, The Southwest Hospital of Army Medical University, Affiliated Hospital of Zunyi Medical University and Shanxi Coal Center Hospital. The total sample size is 150 patients, with 75 patients in the EUS evaluation group and 75 patients in the control group, respectively. The patients who meet the inclusion and exclusion criteria are randomly assigned to EUS evaluation group and control group by using block randomization. The EUS evaluation group uses EUS to observe the diameter and blood flow of residual variceal veins after endoscopic cyanoacrylate injection for GV to evaluate the embolization effect. Endoscopic cyanoacrylate injection is performed again if the diameter of variceal vein is larger than 5 mm and with blood flow signal. After the injection, the blood flow signal is confirmed disappear by EUS. The control group return to the ward after endoscopic cyanoacrylate injection, without EUS evaluation. During the study, the patients are followed up for at least 12 months, and they are requested to return to the hospital for follow-up at 1 month, 3 months, 6 months and 12 months after the treatment, respectively. The data of baseline, treatment, postoperative and follow-up of the two groups are need to collect. The primary outcome of this study is rebleeding rate. Secondary outcomes are eradication rate of GV, mortality rate, retreatment, and cost-effectiveness.
