Filter by:Objectives: To examine whether dynamic Optical Coherence Tomography (OCT) could characterize vessel dimensions and blood flow of telangiectasias before and after treatment with Intense Pulsed Light (IPL). Methods: Dynamic-OCT (D-OCT) imaged telangiectasia characterized blood vessel width and depth, blood flow, and attenuation. Measurements were done immediately before and after, 1-3 days after, and 1 month after IPL treatment. Characterization of vessel dimensions at baseline were verified by a blinded observer. At one-month follow-up, clinical improvement was characterized as good, moderate or none and possible adverse effects were described.
The purpose of this randomised and controlled study is to investigate the effects of Kinesio Taping method and compression stockings, combined with exercise therapy, on pain, edema, functional capacity and quality of life in patients with chronic venous disease. Therefore, the study compares effectiveness of these two methods for chronic venous disease.
This study is a double-blinded, randomized controlled trial to evaluate the efficacy of an intranasal topical timolol gel in the care for epistaxis in adults with hereditary hemorrhagic telangiectasia.
Using of low concentrate sodium tetradecyl sulfate for sclerotherapy of telangiectasias should be no less effective than hypertonic glucose, and have a comparable frequency of adverse events.
Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic disorder of angiogenesis associated with disabling epistaxis. Management of these nose bleedings requires more effective treatment. Propranolol, a beta-blocker, is a potentially useful therapeutic considering its anti-angiogenic properties. Our objective is to explore the efficacy of propranolol, three months after its introduction, on the cumulative duration of epistaxis in HHT patients.
Hereditary hemorrhagic telangiectasia (HHT) is linked to a dysregulation of angiogenesis leading to the formation of arteriovenous malformations (AVM): cutaneo-mucous telangiectasia and visceral shunts. The diagnosis is clinical and based on Curaçao criteria: recurrent epistaxis, cutaneo-mucous telangiectasia, hereditary signs and presence of visceral AVM. Pulmonary AVMs (PAVM) expose patients to many potentially life-threatening complications, such as strokes or brain abscesses due to the right-left shunt created and the lack of filtration barrier of the pulmonary capillary within the AVM. These patients should therefore have regular monitoring throughout their life by a chest CT scanner every 5 to 10 years in the absence of PAVM at the initial scan or more often if PAVMs are present. The management of PAVMs is based on their early detection and embolization in interventional radiology during which is set up within the afferent artery of the PAVM an embolizing agent, the coil. However, the risk of cumulative irradiation exposure from thoracic scanners and repeated thoracic embolizations over time could be reduces by a decrease of X-rays dose. A new thoracic CT imaging protocol validated in the United States in the primary screening of lung cancer, the ultra-low dose protocol, is a CT scanner acquired at an irradiation dose equivalent to that of a frontal chest x-ray and in profile. The dose reduction is of 40 times the usual dose of a chest CT scanner. The lung parenchyma has a high natural contrast on thoracic CT images and there are few adjacent attenuating structures allowing a drastic reduction of dose. However, from this dose, the image quality is degraded with an increase of the image noise. The diagnostic performances have to be confirmed with qualitative and quantitative measurements. Thus, the objective of this study is to compare the sensitivity and the specificity of the current scanner and the ultra-low dose scanner to reduce the exposure to X-rays.
Is 1064 nm YAG Laser better than sclerotherapy to treat leg veins?
This clinical trial investigates the effects of nicotinamide riboside (vitamin B3) on the disease course of patients with ataxia telangiectasia. Patients will be treated during four consecutive months with nicotinamide riboside (25mg/kg/day), followed by a washout period of two months. Main study parameters/endpoints: Ataxia, dysarthria, quality of life, laboratory parameters.
The recognized manifestations of HHT are all due to abnormalities in vascular structure. Epistaxis are spontaneous, very variable, may occur as often as several times every day, and are recurrent in 90% of patients and associated with chronic and severe anemia in 2-10%. They also significantly reduce quality of life. Blood transfusions are sometimes required in 10-30% of patients. Previous studies showed that antiangiogenic treatments such as anti-VEGF treatment (bevacizumab) administered intravenously was efficient on epistaxis and dramatically reduced nosebleeds. Tyrosine kinase inhibitors are anti-angiogenic molecules which are available orally and could therefore overcome the difficulties encountered with bevacizumab. The investigator hypothesized that nintedanib, acting by indirect inhibition of the VEGF receptor should allow a reduction of epistaxis in HHT patient. Nintedanib has been used in one HHT patient following the diagnosis of Insterstitial Pulmonary Fibrosis (published case report in 2017, Kovacs et al) with encouraging results. The aim is to evaluate efficacy of nintedanib for the treatment of epistaxis in HHT patients
Liver transplantation (LT) has been proposed as a curative treatment in hereditary hemorrhagic telangiectasia (HHT) with severe hepatic involvement. The investigating team provides a long-term evaluation of graft status after LT for HHT with a focus on the risk of recurrence. The present study included all patients prospectively followed up after LT for HHT in the Lyon Liver Transplant Unit from 1993 to 2010 with a survival of more than 1 year.
