Active clinical trials for "Hemorrhage"

The investigators prepared a novel tranexamic acid (TXA) study designed to estimate the quantity of blood loss in patients undergoing breast esthetic surgery. This study aims to quantify blood loss during abdominoplasty with and without TXA. The central hypothesis is that TXA administration reduces blood loss and fibrinolysis in breast esthetic surgery patients.

The goal of this randomized clinical trial is to evaluate the impact of an expert opinion during the management of patients with severe bleeding on oral anticoagulants. The main question it aims to answer is : • Does an expert help of decision during the management of patients with severe bleeding is superior to classic management ? The centers will be randomized in one of the two groups : control group and interventional group. Patients will be followed for 3 months. At their inclusion they will be managed in conformity of the randomisation of their center. They will be followed at hour 0 + 6 , H0+24 and at the end of hospitalization. After 3 months, they will be called to assess the occurrence of thrombotic events ou hemorrhage complications. Researchers will compare the classic management versus the management with an expert opinion to see if the expert opinion is superior to classic management.

The primary objective of this study is to demonstrate the superior efficacy versus placebo of BG2109 alone and in combination with add-back therapy for the reduction of heavy menstrual bleeding associated with uterine fibroids in premenopausal women.

Dual antiplatelet agent therapy (DAPT) is essential in treating PCI patients. DAPT can minimize thrombotic adverse events that occur not only at the stented lesion, but along the whole coronary tree. However, DAPT has a critical side effect of increasing bleeding complications. Addressing the clinical imperatives of lowering bleeding while preserving ischemic benefit requires therapeutic strategies that decouple thrombotic from hemorrhagic risk. Recently, the ARC definition of high bleeding risk (HBR) has been published, so as to stress the need of optimal DAPT treatment in HBR patients. Due to the definitely higher bleeding risk in HBR patients, it would be rather more straight forward to titrate the optimal DAPT duration in these patients. In this line, many studies are in progress on HBR patients, with an ultra-short DAPT duration (i.e. Leaders free, Onyx ONE, Master DAPT, Xience 28, Xience 90, Evolve short DAPT trial, etc.). As a counteract to the definition of HBR, there is a concept of LBR. Due to the relatively vague ischemic/bleeding risk in LBR patients, balancing ischemic and bleeding complications post-PCI is more difficult in LBR patients, which may be a more important dilemma for clinicians. In this regards, limited evidence exists on the optimal duration of DAPT in LBR patients. Various previous studies that have evaluated the optimal DAPT in PCI populations, did not have the concept of HBR or LBR, making interpretation difficult. Therefore, this study is planning to compare the efficacy and safety of different DAPT durations, in patients stratified according to the ARB-HBR definition.

The goal of this clinical trial is to evaluate efficacy and safety of evacuation of cerebrospinal fluid, blood, and harmful bacteria from the intraventricular, subdural and subarachnoid spaces by Active Controlled Irrigation and Drainage (IRRAflow) compared to Passive External Ventricular Drainage (EVD). Subjects with intraventricular hemorrhage, subarachnoid hemorrhage, subdural bleeding, and ventriculitis will be randomized to receive the IRRAflow device or EVD device and followed for one month post-procedure to compare outcomes between the subject groups.

DCB-HBR trial is prospective, multi-center, open-label, randomized controlled, noninferiority trial. The aim of the study is to compare clinical outcomes of drug-coated balloon (DCB) with drug-eluting stent (DES) for treatment of de-novo coronary lesion under intravascular imaging-guided optimization in patients with high bleeding risk (HBR).

Diabetic retinopathy (DR) is one of the main complications in diabetes, the proliferative diabetic retinopathy (PDR) is the most important one of the reasons leading to decreased vision, PDR is the stage of clinical intervention. Pars plana vitrectomy (PPV) is an effective treatment for PDR, while vitreous haemorrhage (VH) is a common complication after PPV, with incidence ranging from 11.8% to 75%, and is the main cause of reoperation. Anti-Vascular endothelial growth factor (VEGF) therapy for vitreous hemorrhage can inhibit neovascularization and prevent recurrent vitreous haemorrhage after absorption. Previous studies have found that anti-VEGF is a safe and effective treatment for postoperative recurrent VH. In consideration of the psychological and economic factor of patients, this study intends to observe the effectiveness of single vitreous injection of Ranibizumab in the treatment of postoperative recurrent VH on the basis of previous clinical work. Compare the visual acuity, macular thickness, VH recurrence and patient satisfaction between the Ranibizumab group and the PPV group by randomized grouping.To observe the effective rate and clearance time of recurrent VH after Ranibizumab treatment and whether it can effectively reduce the rate of PPV. To provide clinical guidance for the precise treatment of PDR patients, the treatment of PDR patients has important clinical significance and social and economic significance.

The objective of this study is to assess the efficacy of an implantable etonogestrel device in reducing hysterectomy rate in patients with a failed endometrial ablation.

Cerebral vasospasm is characterized by a vasoconstriction of cerebral arteries causing a reduction of cerebral blood flow (CBF) and leading to ischemia and infarction of the brain parenchyma. Cerebral vasospasm is a serious complication of aneurysmal subarachnoid hemorrhage (SAH) with high morbidity and overall mortality of 40-50%. Although the exact mechanisms of spinal cord stimulation (SCS) on the innervation of cerebral vessels are still unclear, several hypotheses have been formulated and studies in animals and human performed with very promising results. This is a proof of concept study to better understand the effect and mechanisms of cervical spinal cord stimulation on cerebral vasospasm after aneurysmal SAH in human.
