Residual vein thrombosis for assessing duration of anticoagulation after unprovoked deep vein thrombosis of the lower limbs: the extended DACUS study.

2011

Abstract The safest duration of anticoagulation after idiopathic deep vein thrombosis (DVT) is unknown. We conducted a prospective study to assess the optimal duration of vitamin K antagonist (VKA) therapy considering the risk of recurrence of thrombosis according to residual vein thrombosis (RVT). Patients with a first unprovoked DVT were evaluated for the presence of RVT after 3 months of VKA administration; those without RVT suspended VKA, while those with RVT continued oral anticoagulation for up to 2 years. Recurrent thrombosis and/or bleeding events were recorded during treatment (RVT group) and 1 year after VKA withdrawal (both groups). Among 409 patients evaluated for unprovoked DVT…

Residual vein obstruction in patients diagnosed with acute isolated distal deep vein thrombosis associated with active cancer.

2018

After acute proximal deep vein thrombosis (DVT) the thrombotic mass decreases, especially during the first months of anticoagulation. The persistence of residual vein obstruction (RVO) may predict future recurrence in patients with cancer-associated DVT. We aimed to evaluate the proportion of patients with RVO after an episode of cancer associated isolated distal DVT (IDDVT), to identify variables associated with RVO, and to provide initial evidence of its association with recurrent VTE. We performed a post-hoc analysis of a multicenter cohort study of patients with isolated cancer-associated acute IDDVT. We included patients who underwent a control ultrasonography at the end of the anticoa…

Residual vein thrombosis to establish duration of anticoagulation after a first episode of deep vein thrombosis: the Duration of Anticoagulation base…

2008

Abstract Residual vein thrombosis (RVT) indicates a prothrombotic state and is useful for evaluating the optimal duration of oral anticoagulant treatment (OAT). Patients with a first episode of deep vein thrombosis, treated with OAT for 3 months, were managed according to RVT findings. Those with RVT were randomized to either stop or continue anticoagulants for 9 additional months, whereas in those without RVT, OAT was stopped. Outcomes were recurrent venous thromboembolism and/or major bleeding. Residual thrombosis was detected in 180 (69.8%) of 258 patients; recurrent events occurred in 27.2% of those who discontinued (25/92; 15.2% person-years) and 19.3% of those who continued OAT (17/88…

Paradoxical embolism through a patent foramen ovale from central venous catheter thrombosis: A potential cause of stroke

2020

Paradoxical embolism refers to a potential condition in which an embolus arising from a venous source crosses into the systemic circulation through a right-to-left cardiac shunt causing an arterial embolism. A 39-year-old woman carrier of a central venous catheter (CVC) without evident risk factors for stroke, developed an acute right homonymous hemianopia during hemodialysis. On neuroimaging, an infarct in the territory of the left posterior cerebral artery was demonstrated. Transesophageal echocardiography revealed a patent foramen ovale (PFO) and a large fluctuating thrombus in the right atrium on the tip of the CVC, thus allowing a diagnosis of ischemic stroke from paradoxical embolism.…

Portal vein thrombosis and Budd-Chiari syndrome as onset of polycythemia vera

2013

Budd-Chiari syndrome may be defined as a heterogeneous group of vascular disorders characterized by obstruction of hepatic venous return to the level of hepatic venules, supra-hepatic veins, inferior vena cava or right atrium. The main cause of this syndrome is represented by myeloproliferative diseases and, in particular, by polycythemia vera. The latter may cause multiple splanchnic thrombosis, including portal vein thrombosis, particularly important for its clinical outcomes (ascites, collateral vessels genesis, etc.). We report 2 cases of a Budd-Chiari syndrome induced by polycythemia vera characterized by an abnormal clinical onset, both as regards subjects’ age (29 and 39 years old, r…

Optimal duration of low molecular weight heparin for the treatment of cancer-related deep vein thrombosis. The ”CANCER DACUS” study

2014

Purpose We evaluated the role of residual vein thrombosis (RVT) to assess the optimal duration of anticoagulants in patients with cancer who have deep vein thrombosis (DVT) of the lower limbs. Patients and Methods Patients with active cancer and a first episode of DVT treated with low molecular weight heparin (LMWH) for 6 months were eligible. Patients were managed according to RVT findings: those with RVT were randomly assigned to continue LMWH for an additional 6 months (group A1) or to discontinue it (group A2), and patients without RVT stopped LMWH (group B). The primary end point was recurrent venous thromboembolism (VTE) during the 1 year after disconinuation of LMWH, and the secondar…

Comparison of heparin to citrate as a catheter locking solution for non-tunneled central venous hemodialysis catheters in patients requiring renal re…

2014

Background The incidence of acute kidney injury (AKI) is estimated at 10 to 20% in patients admitted to intensive care units (ICU) and often requires renal replacement therapy (RRT). ICU mortality in AKI patients can exceed 50%. Venous catheters are the preferred vascular access method for AKI patients requiring RRT, but carry a risk of catheter thrombosis or infection. Catheter lock solutions are commonly used to prevent such complications. Heparin and citrate locks are both widely used for tunneled, long-term catheters, but few studies have compared citrate versus heparin for patients with short-term, non-tunneled catheters. We aim to compare citrate 4% catheter lock solution versus hepar…
