Rationale: Recently our study group reported the results of the Basilar Artery International Cooperation Study (BASICS), a prospective registry of patients with an acute symptomatic basilar artery occlusion (BAO). Our observations in the BASICS registry underscore that we continue to lack a proven treatment modality for patients with an acute BAO and that current clinical practice varies widely. Furthermore, the often-held assumption that intra-arterial thrombolysis (IAT) is superior to intravenous thrombolysis (IVT) in patients with an acute symptomatic BAO is challenged by our data. The BASICS registry was observational and has all the limitations of a non-randomised study. Interpretation of results is hampered by the lack of a standard treatment protocol for all patients who entered the study. Objective: Evaluate the efficacy and safety of IAT in addition to best medical management (BMM) in patients with basilar artery occlusion. Study design: Randomised, multi-centre, open label, controlled phase III, treatment trial. Study population: Patients, aged 18 years and older, with CTA or MRA confirmed basilar occlusion. Intervention: Patients will be randomised between BMM with additional IAT versus BMM alone. IAT has to be initiated within 6 hours from estimated time of BAO. If treated with as part of BMM, IVT should be started within 4.5 hours of estimated time of BAO. Main study parameters/endpoints: Favorable outcome at day 90 defined as a modified Rankin Score (mRS - functional scale) of 0-3.
This is a large prospective registry of patients submitted to cardiac electronic devices implantation designed to investigate the incidence, risk factors and prognostic of thromboembolic complications associated with transvenous lead implantation.
The purpose of this study is to determine whether pharmacogenetic guided dosing of warfarin is promising for the improvement of efficiency, therapeutic efficacy, and, especially, safety of warfarin therapy than a dosing regimen without the pharmacogenetic information in Chinese patients initiated on warfarin anticoagulation.
In selected patients with acute pulmonary embolism(PE), low dose (50mg/2h) recombinant tissue plasminogen activator (rt-PA) regimen had been reported to have less bleeding tendency than the FDA-approved rt-PA 100mg/2h regimen 100mg/2h regimen (3% vs.10%), it is worthwhile to reveal whether low dose rt-PA plus low molecular weight heparin (LMWH) can rapidly reverses RV pressure overload in PE, but not increase bleeding and other adverse events. The aim of the study is to compare thrombolytic treatment with LMWH in patients with acute normotensive PE with right ventricular dysfunction(RVD).
The purpose of this study is to create an institutional registry of Thromboembolic disease through a prospective survey based on epidemiological data, risk factors, diagnosis, prognosis, treatment, monitoring and survival. The main goal is to describe the occurrence of thromboembolic disease and the characteristics of clinical presentation, evolution and predisposing factors of these episodes in the population of the Hospital Italiano de Buenos Aires.
The purpose of this study is to determine whether a limited duration of treatment (two weeks of low molecular weight treatment) is a safe and effective treatment for distal deep vein thrombosis of the lower limb.
This is a prospective, observational, multicenter study. The primary aim of the study is to assess the accuracy of spiral CT scan to detect right ventricular dysfunction as compared to current 'gold standard'in patients with pulmonary embolism. At the purpose of this study right ventricular dysfunction as assessed by transthoracic echocardiography and serum levels of troponin are considered as gold standard. The secondary aim of the study is to assess the prognostic value of right ventricular dysfunction as assessed by spiral CT scan.
Two studies (Gerlach et al. 2000; Gerlach et al. 2002) described the impact of factor XIII on the risk of prospective hemorrhage for patients undergoing craniotomy. Since then, factor XIII is measured and substituted in various centers. Few reports support the idea of factor XIII being involved in the formation of deep venous thrombosis and pulmonary embolism. In this prospective observational study, patients undergoing craniotomy for brain tumors or vascular lesions are investigated concerning the incidence of postoperative pulmonary embolism in respect of possible risk factors (factor XIII activity levels, standard coagulation parameters, tumor entity, blood loss).
The prospective, randomized, two centre study investigates acute cerebrovascular events during extracorporal circulation and the early post operative outcome when using either the minimized cardiopulmonary bypass circuit (ROCsafeTM) or a standard cardiopulmonary bypass circuit in patients undergoing coronary artery bypass grafting.
