[Venous thrombembolism in tumour patients]

Venous thrombembolism (VTE) is one of the most frequent complication in cancer patients. The current options in prophylaxis and therapy have to be balanced against the risks of major bleeding and the burden for the patients. The Gesellschaft für Thrombose- und Hämostaseforschung, the Deutsche Gesellschaft für Palliativmedizin and the German speaking Societies of Hematology and Oncology have recently published guidelines on VTE in cancer patients. Recommendations include diagnostics, individual prophylaxis and treatment.

Comparison of arterial and venous coronary artery bypass flow measurements using 3-T magnetic resonance phase contrast imaging

Comparison of arterial and venous coronary artery bypass flow measurements using 3-T magnetic resonance (MR) phase contrast in correlation with intraoperative Doppler flow measurements.

[Surgical options in the treatment of chronic venous ulcers]

Surgery offers several options in prevention of chronic venous insufficiency and its sequelae. Both the operation on veins with valve dysfunction to reduce reflux and the elimination of obstruction in thrombosed veins aim for the reduction of venous hypertension. Elevated venous pressure, impairment of cutaneous capillaries and a chronic inflammatory process result in sclerosis of skin and subcutaneous tissue and might proceed to the fascia resulting in a chronic compartment syndrome. Non- healing chronic venous ulcers under conservative therapy for more than three months may be treated by vein-surgery, local wound care therapy like shaving and negative pressure treatment and if necessary by lowering of elevated intracompartimental pressure by fasciotomy or even fasciectomy.

Improved microsurgical creation of venous pouch arterial bifurcation aneurysms in rabbits

The choice of the experimental aneurysm model is essential for valid embolization-device evaluations. So far, the use of the rabbit venous pouch arterial bifurcation aneurysm model has been limited by demanding microsurgery, low aneurysm patency rates, and high mortality. This study aimed to facilitate microsurgery and to reduce mortality by optimized peri-/postoperative management.

Pharmacological treatment of primary chronic venous disease: rationale, results and unanswered questions

The aim of this article was first to review the complex pathophysiological mechanisms responsible for symptoms and signs of primary chronic venous disease (CVD) that allow the identification of targets for pharmacological treatment. The results of CVD treatment with venoactive drugs (VADs) were emphasised and presented in the form of recommendations. The last section raises key questions to be answered to improve protocols for good clinical trials and to draw up future guidelines on these agents.

Primary prophylaxis for venous thromboembolism in ambulatory cancer patients receiving chemotherapy

Venous thromboembolism (VTE) often complicates the clinical course of cancer disease. The risk is further increased by chemotherapy but the safety and efficacy of primary thromboprophylaxis in cancer patients treated with chemotherapy is uncertain.

Identification of venous variants in the pineal region with three-dimensional preoperative magnetic resonance imaging navigation in patients harbouring tumors in this area: significance for surgical approach to the lesion

The purpose of this study was to identify the anatomy of pineal region venous complex using neuronavigation software when distorted by the presence of a space-occupying lesion and to describe the anatomical relationship between lesion and veins. Moreover we discuss its influence on the choice of the surgical strategy.

Relation of psychological distress to the INR in Patients with venous thromboembolism with and without oral anticoagulant therapy

Psychological distress might affect the international normalized ratio (INR), but effects might vary depending on oral anticoagulant (OAC) therapy.

Depressive symptoms, perceived social support, and prothrombotic measures in patients with venous thromboembolism

Psychosocial factors have been associated with both a prothrombotic state and an increased risk of venous thromboembolism (VTE). We examined the relation of depressive symptoms and social support with D-dimer, an integrative measure of enhanced coagulation activity, and several additional prothrombotic measures in patients with VTE.

Insertion of totally implantable venous access devices: an expertise-based, randomized, controlled trial (NCT00600444)

Comparison of two different insertion techniques for implantation of totally implantable access ports (TIAP).

Prospective, multicenter validation of prediction scores for major bleeding in elderly patients with venous thromboembolism

The Outpatient Bleeding Risk Index (OBRI) and the Kuijer, RIETE and Kearon scores are clinical prognostic scores for bleeding in patients receiving oral anticoagulants for venous thromboembolism (VTE). We prospectively compared the performance of these scores in elderly patients with VTE.
