Enoxaparin thromboprophylaxis dosing and antifactor Xa levels in low ‐weight patients
ConclusionA lower dose of enoxaparin may be reasonable in low ‐weight patients for VTE prophylaxis. There appears to be no safety concerns with reduced enoxaparin dosing in low‐weight patients. More robust data is needed to confirm these findings.This article is protected by copyright. All rights reserved.
ConclusionsEndoscopic imaging of the venous system has great potential to improve access and to guide endovenous interventions. Chronic venous occlusion in post-thrombotic syndrome is a fibrotic process, and chronic venous fibrosis is a better description of the type of occlusion and should replace chronic venous thrombosis.
ConclusionsPostural changes dramatically affect CSA of the LCIV and LRV and thus the degree of stenosis in women diagnosed with PVD. Stenosis found in patients while supine often disappears when the position is changed to lying on the left side or to standing. Therapeutic decisions based on assessment of CSA reduction in the supine position are likely to be inadequate.
ConclusionPortomesenteric venous thrombosis is an uncommon yet potentially fatal complication of bariatric surgery. A high index of suspicion, early diagnosis and subsequent adequate management is required. Based on this case series and the potential risk of portomesenteric venous thrombosis, we altered our clinical practice to include a 1 week course of low molecular weight heparin to be administered to all patients after discharge.
The objectives of this study were to characterize the kinetics of thrombus resolution and to define an appropriate duration of anticoagulation and interval for surveillance US.
Current arteriovenous grafts (AVGs) have unacceptably high failure rates. This issue led to the development of tissue-engineered vascular grafts in an attempt to mimic a native blood vessel. We hypothesized that a novel synthetic vascular graft could be developed using electrospinning technology that functions as scaffolding for cell ingrowth, thereby providing the added natural protection of native cells against thrombosis and infection. The resulting graft would also maintain the strength, kink resistance, and safety with cannulation that standard synthetic AVGs provide.
The radiocephalic arteriovenous fistula (AVF) is the preferred standard for patients needing primary hemodialysis access creation. In patients who lack suitable superficial veins in the distal upper extremity, proximal native vessels or synthetic grafts are often used. However, proximal primary access creation results in loss of vascular territory for future interventions, and grafts and proximal vessels have been shown to be inferior starting points because of higher risk of infection, thrombosis, and steal syndrome.
The objective of this study was to assess the use and consequences of upper extremity duplex ultrasound (U/S) in the initial diagnostic evaluation of patients with suspected subclavian vein (SCV) thrombosis and venous thoracic outlet syndrome (VTOS).
This study aims to assess our experience with TEVAR to induce FLT and aortic remodeling in TBAD.
In this study, we used large-scale electronic health records data from multiple linked UK databases to address these evidence gaps.MethodsFor this population-based cohort study, we used linked primary care, hospital, and cancer registry data from the UK Clinical Practice Research Datalink to identify cohorts of survivors of the 20 most common cancers who were 18 years or older and alive 12 months after diagnosis and controls without history of cancer, matched for age, sex, and general practice. We compared risks for a range of cardiovascular disease outcomes using crude and adjusted Cox models. We fitted interactions to in...
