Thrombophili

BACKGROUND: Over the past decades, thrombophilia testing in patients with venous thrombo-embolism has increased tremendously. However, the role of inherited thrombophilie in prediction the risk of recurrence remains controversial. Consequently, it is still unclear whether thrombophilia testing influences decisions regarding duration of anticoagulation in clinical practices. The aim of this study was to evaluate the impact if inherited thrombophilia on venous thrombosis treatment decisions and on predicting the risk of recurrence...

Monitoring of vitamin K antagonist treatment with the international normalized ratio (INR) is obligatory, whereas this only applies to direct oral anticoagulants (DOAC) or low molecular weight heparin in the context of selected clinical scenarios. For DOAC the focus is on the determination of trough and peak plasma levels of the drug but for low molecular weight heparins the focus is on anti-Xa activity. The timing of blood sampling in relation to drug intake is essential for the interpretation of the results...

HINTERGRUND: Bei einer Schaumsklerosierungstherapie von Varizen können als Nebenwirkungen sowohl tiefe (TVT) als auch oberflächliche Beinvenenthrombosen (OVT) auftreten. Noch weitgehend unklar sind die Risikofaktoren, welche die Entstehung einer OVT oder TVT nach Schaumsklerosierung begünstigen. Das Ziel dieser retrospektiven Analyse war, anhand eines größeren Kollektivs von Patienten mit thromboembolischen Komplikationen sowohl patienten- als auch eingriffsbezogene Risikofaktoren für thromboembolische Komplikationen durch eine Schaumsklerosierung herauszuarbeiten...

INTRODUCTION: Venous thrombosis of unusual sites is much rarer than in the lower limbs and requires a rigorous etiological approach. The objective was to describe the clinical and progressive peculiarities of unusual localization venous thrombosis as well as their etiologies. PATIENTS AND METHODS: Multicenter descriptive retrospective study of hospitalized patient records in the two large Hospital Centers, Antananarivo, Madagascar between 2017 and 2020 in which the diagnosis of unusual venous thrombosis was confirmed by imaging...

OBJECTIVE: Introduction: Thrombophiliа is a predisposition to arterial or venous thrombotic complications as a result of congenital or acquired hemostatic system defects. Thrombophilia increases risk of fatal complications, disability of patients. The assessment of the risk of thrombotic complications makes it possible to prescribe adequate primary or secondary prophylaxis. However, there is no systematic information about estimation risk of thrombosis in various types of thrombophilia and conduction primary and secondary prophylaxis of thrombotic complications, choosing treatment...

Venous thromboembolic disease in childhood is a multifactorial disease. Risk factors include acquired clinical risk factors such as a central venous catheter and underlying disease and inherited thrombophilia. Inherited thrombophilia is defined as a genetically determined tendency to develop venous thromboembolism. In contrast to adults, acquired clinical risk factors play a larger role than inherited thrombophilia in the development of thrombotic disease in children. The contributing role of inherited thrombophilia is not clear in many pediatric thrombotic events, especially catheter-related thrombosis...

AIM: We aimed to evaluate the patients who were followed up in our clinic with a diagnosis of cerebral sinovenous thrombosis in terms of age, sex, clinical findings, etiology, thrombophilic factors, imaging findings, treatment and prognosis. MATERIAL AND METHODS: The files of 11 patients who were followed up in our pediatric neurology clinic with a diagnosis of cerebral thrombosis between 1 December 2010 and 31 December 2014 were retrospectively analyzed. RESULTS: Seven of 11 patients were male (63...

Prothrombin mutation, in the same way as the factor V Leiden, is a thrombophilic state susceptible to induce both thrombosis and repetition of miscarriages at pregnancy woman. We report a case of 36 year-old woman who presented two miscarriages leaded to thrombophily state diagnosis by prothrombin mutation and among which two last pregnancies were led to their term thanks to anticoagulation.

The aim of this study is to evaluate the frequency of protein C deficiency in venous thromboembolism in black African patients of Benin. It is a descriptive study. Inclusion criteria were: acceptance- having a venous thromboembolism. No exlusion criteria was retained. Protein C deficiency was diagnosed by quantitative technic with a Minividas materiel in the blood. Protein C dosage has been done before antivitamin k therapy and a second dosage has been done if the first one demonstrated a low level of protein C...

Congenital extremity anomalies have many modes of presentation. Interruption of vascular supply with thrombophily is a rare cause of congenital extremity absence. Here it is presented a 7 mth old male with absence of the left lower extremity. Laboratory tests revealed Factor V Leiden and Prothrombin G20210A heterozygote mutation and that was as the cause of extremity absence. At the patients with congenital extremity absences, it is not imprudent to explore a possible thrombophilic mutation along with other known etiologic factors...

BACKGROUND: At the beginning the antiphospholipid antibodies syndrome was associated with systemic lupus erythematosus. But since 1988 it has become a sole entity. Its current definition is based on the criteria established in 1999 by Sapporo and consists of associating the clinical criteria of thrombosis of arteries or peripheral veins and of miscarriage of pregnancy with the biological criteria. Either anti-cardiolipin antibodies or lupus anticoagulant must be present. Anti-phosphatidylethanolamine antibodies are not included in the Sapporo criteria...

Since March 1999, desirudin (REVASC), a recombinant hirudin, has been used in Nancy to treat patients who undergo total hip or knee replacement with a high risk of thromboembolic complications. We carried out a retrospective study using clinical data on the first 15 consecutive patients treated with desirudin to find out prescription motivations, type of shift (indirect anticoagulants or low-molecular-weight-heparin) and evolution. They all had a high risk of deep vein thrombosis (thrombophily, obesity, history of thromboembolic events)...

Homocysteine results from the demethylation of the essential amino acid methionine. Its metabolism depends primarily on three enzymes and several vitamin cofactors (vit. B6, B9 and B12). Genetic abnormality in these enzymes or deficiency of these vitamins lead to Hyperhomocysteinemia. Hyperhomocysteinemia belongs among the congenital thrombophilies and is a long-known vascular disease risk factor. The discovery that hyperhomocysteinemia may also be responsible for several pregnancy complications has only recently been made...
