Filter by:Chronic Venous Disease (CVD) has a high prevalence in the general population of the western world. Varicose veins are the main signs of this disease that are characterized by important pathological vessel wall changes. There are also several symptoms that affect the quality of life of affected patients. The aim of this study is to correlate the main histopathological abnormalities with the type and the intensity of the symptoms.
This study will be evaluate the clinical efficacy of micronized purified flavonoid fraction (MPFF) phlebotropic therapy for postoperative pain, venospecific symptoms, and quality of life in patients with incompetent great or small saphenous veins (GSV/SSV) following an endovenous mechanochemical ablation procedure (MOCA).
The aim of this study is to report a collaborative, prospective Singaporean experience using the Endovenous Radio Frequency® (EVRF®) from F Care Systems (Belgian) for the treatment of primary great and short saphenous vein reflux.
This seamless, adaptive, two-stage, Phase 2b/3, randomized, double-blind, multicenter, parallel-groups, placebo-controlled study will assess the efficacy, safety, and tolerability of belapectin compared with placebo in patients with nonalcoholic steatohepatitis (NASH) cirrhosis and clinical signs of portal hypertension but without esophageal varices at baseline.
The aim of the study is to evaluate the efficacy of non-invasive echotherapy for the treatment of varicose veins, within local population, using the Sonovein® device. The quality of life scores at baseline, 2 weeks, 3 months, 6 months and 12 months will be assessed using the EQ-50D, AVVQ and CIVIQ scores. Patient satisfaction at these time points will also be assessed.
To assess the efficacy of the Venablock©Vein Sealing System (VBVS) for the treatment of lower extremity superficial truncal veins in a real-world clinical setting in a multi-racial Asian population in Singapore.
Variceal hemorrhage is the serious complication in patients with compensated advanced chronic liver disease (cACLD). To evaluate the bleeding risk of varices in cACLD, esophagogastroduodenoscopy (EGD) should be performed. Once identified with medium-large varices, or small varices with red signs or Child-Pugh C class, defined as varices needing treatment (VNT), the patients with cACLD are recommended to receive the non-selective beta blockers or endoscopic variceal ligation per Baveno VI consensus. However, EGD is limited by its invasiveness and uncomfortableness. The Baveno VI criteria, which was validated by 310 patients dominant with hepatitis C virus (55.0%), recommended that EGD could be spared in patients with liver stiffness (LS) < 20kPa and platelet count > 150×10^9 cells/L. Furthermore, the expanded-Baveno VI criteria (LS < 25kPa and platelet count > 110×10^9 cells/L), based on European cohort with hepatitis C virus (62.8%), was able to spare more unnecessary endoscopies than the Baveno VI criteria with VNT missed rate < 5%. Nevertheless, a recent Asian-pacific study indicated that though Baveno VI criteria was able to avoid screening endoscopy with 27.6%, it increased the odds of missing VNT in hepatitis B virus-related cACLD. Notably, this study also suggested that the expanded-Baveno VI criteria was not suited for Asian-pacific cohort with hepatitis B virus as the dominant cause with VNT missed rate > 5%. Our study aims to develop and validate an optimal cutoff value of LS and platelet count (CHESS criteria) to safely avoid more unnecessary endoscopies in patients with hepatitis B virus-dominated cACLD.
This is a one-arm, open label, prospective, single center study to evaluate clinical standardization with Theraclion's Sonovein 2 HIFU device. The original Sonovein device was tested in a clinical trial in 50 subjects and received CE Mark. That device has been updated yielding the current version of Sonovein 2. Based on the technical similarities between both devices in term of design, performance and principle of operation, the clinical data for Sonovein is sufficient to assure conformity of the Sonovein 2 with the respected essential requirements. At the same time, the compagny wishes to pursue the standardisation of the clinical practice with the second generation device and is, therefore, conducting this limited trial in 20 evaluable cases (from the planned 22 patients to be included). A "case" is defined as procedure conducted on a distinct vein.
Hypothesis. Regular using of Class 1 below-knee graduated compression stockings (RAL GZ 387 standard) compared to the absence of elastic compression will reduce the risk of clinically significant varicose veins recurrence at 12 months after endovenous thermal ablation of the great saphenous vein and elimination of varicose tributaries.
Gastric varices occur in patients with portal hypertension, mostly secondary to liver cirrhosis. Although they bleed less frequently than oesophageal varices, gastric variceal bleeding tends to be more severe with reported higher mortality. Endoscopic variceal obliteration (EVO) by direct endoscopic injection (DEI) using tissue adhesives like glue, CYA or histoacryl demonstrated higher hemostasis and lower bleeding rates compared to band ligation or sclerotherapy. Nevertheless, CYA treatment is known to be associated with significant adverse events like para-variceal injection, hemorrhage from post injection ulcer, needle sticking in the varix, intra-peritoneal injection leading to peritonitis and adherence of the glue to the endoscope, fever, embolization into the renal vein, IVC, pulmonary or systemic vessels. Endoscopic ultrasound (EUS) offers unique access to abdominal arterial and venous vasculature. This has had the most clinical impact on the treatment of gastroesophageal varices, where EUS may play a role both in the management and can deliver therapy in the form of glue injection, endovascular coil placement or a combination of the two. EUS enables an assessment using Doppler to confirm vessel obliteration after treatment. However, targeting the perforating feeder vessel rather than the varix lumen itself may theoretically minimize the amount of CYA needed to achieve obliteration of GVs and thereby reduce the risk of embolization.
