Patients with overgrowth and complex vascular malformation syndromes, including Proteus syndrome have an increased risk of thromboembolism. Proteus syndrome is a mosaic, progressive overgrowth disorder involving vasculature, skin, and skeleton, and caused by a somatic activating mutation in AKT1. We conducted a comprehensive review of the medical histories and hematologic evaluations of 57 patients with Proteus syndrome to identify potential risk factors for thrombosis. We found that six of ten patients, who were deceased, died secondary to deep venous thrombosis and/or pulmonary embolism...

BACKGROUND: The value of genetic thrombophilia testing in elderly patients with an unprovoked venous thromboembolism is unclear. We assessed whether the factor V Leiden and the prothrombin G20210A mutation are associated with recurrent venous thromboembolism in elderly patients in a prospective multicenter cohort study. METHODS: We genotyped the factor V Leiden and the prothrombin G20210A mutation in 354 consecutive in- and outpatients aged ≥65 years with a first unprovoked venous thromboembolism from nine Swiss hospitals...

OBJECTIVE: At present, there is growing evidence of the existence of a genetic predisposition in both thrombophilic disorders and endometriosis. The aim of our study was to evaluate for the first time the prevalence of some thrombophilic disorders in patients with endometriosis. MATERIALS AND METHODS: We conducted a retrospective study on 138 patients with endometriosis and 278 healthy control women. All women were subjected to a blood examination testing for thrombophilic screening and the variables examinated were: hyperhomocysteinemia, factor V Leiden and factor II prothrombin G20210A mutations in heterozygosis and homozigosis...

BACKGROUND: Based on a number of small observational studies, cerebral venous sinus thrombosis has diverse clinical and imaging features, risk factors, and variable outcome. In a large, multicenter cerebral venous thrombosis (VENOST) study, we sought to more precisely characterize the clinical characteristics of Caucasian patients. METHODS: All data for the VENOST study were collected between the years 2000 and 2015 from the clinical follow-up files. Clinical and radiological characteristics, risk factors, and outcomes were compared in terms of age and sex distribution...

Activated factor V (FVa) and factor X (FXa) form prothrombinase, which converts prothrombin to thrombin. The α isoform of tissue factor (TF) pathway inhibitor (TFPI) dampens early procoagulant events, partly by interacting with FV. FV Leiden (FVL) is the most common genetic thrombophilia in Caucasians. Thrombosis risk is particularly elevated in women with FVL taking oral contraceptives, which produce acquired TFPIα deficiency. In mice, FVL combined with 50% reduction in TFPI causes severe thrombosis and perinatal lethality...

Non-cirrhotic, non-malignant portal vein thrombosis (PVT) is commonly secondary to inherited or acquired prothrombotic states. However, even after extensive workup, 25% of patients with PVT have no apparent prothrombotic aetiology identified (idiopathic PVT). Inherited conditions include factor V Leiden, PT mutation and protein C/S/AT deficiency. Acquired conditions include APS, PNH and BCR-ABL 1-negative myeloproliferative neoplasms (MPN). BCR-ABL-1 negative MPNs are the most frequent underlying prothrombotic risk factor for PVT (15%-30%)...

AIM: The aim of this study was to examine the role of hereditary thrombophilia in the development of fetal growth retardation (FGR) in the population of Central Russia. METHODS: The case-control study sample included 497 women in the third trimester of pregnancy recruited during 2009-2013. The participants were enrolled into two groups: patients with FGR (n = 250) and controls without FGR (n = 247). The participants were genotyped for four genetic markers of hereditary thrombophilia: factor V Leiden (G > A FV, rs6025), prothrombin (G > A FII, rs1799963), factor VII (G > A FVII, rs6046), and fibrinogen (G > A FI, rs1800790)...

In adults, the most common cause of sudden death is coronary heart disease or defects in the cardiac conduction system; however, there are many cases of sudden death occurring from other causes such as fatal pulmonary thromboembolism. Several risk factors are recognized, including hospitalization, surgery, obesity, pregnancy, the use of oral contraceptives, traumatic fractures, and genetic conditions, which cause hypercoagulable states such as factor V Leiden mutations. Although many risk factors have been identified, the mortality rate is still high...

A 52-year-old man with a history of factor V Leiden thrombophilia, persistent headaches and papilloedema presented with worsening vision and confusion. MRI and MR angiography of the brain at the time of this presentation showed findings concerning for transverse sinus thrombosis and an associated dural arteriovenous fistula. Dural venous sinus thrombosis can lead to the formation of a dural arteriovenous fistula, which must be considered in the differential diagnosis for intracranial hypertension in patients with thrombophilia...

BACKGROUND: Superficial vein thrombosis is a common venous condition. Recent studies have shown that SVT is associated with high frequency of thromboembolic complications: from 22 to 37 % for deep venous thrombosis and up to 33% for pulmonary embolism. OBJECTIVES: To assess the prevalence of major hereditary and acquired thrombophilic factors in patients with SVT. PATIENTS AND METHODS: 66 patients presenting with primary ST underwent evaluation for thrombophilia: molecular testing for the factor V Leiden and factor II G20210A (prothrombin) mutations, protein C, protein S, antithrombin deficiency, presence of lupus anticoagulant, as well as anti-cardiolipin antibody titers...

In acute portal vein thrombosis (APVT) unrelated to cirrhosis, anticoagulant therapy is classically started with low molecular weight heparin or vitamin K antagonists. New direct-acting oral anticoagulants (DOACs) are used in the treatment of venous thrombosis outside the splanchnic vascular bed, but not in the latter. We report a young female with APVT occurring in a non-cirrhotic liver linked to heterozygosity of factor V-Leiden and prothrombin G20210A gene mutations. Rivaroxaban was started, with total recanalization of the left and partial recanalization of the right portal vein branches, without complications...

BACKGROUND: Atrial fibrillation is the most common cardiac arrhythmia. It is responsible for up to 20% of all ischemic strokes. Rate control and anticoagulation are crucial for atrial fibrillation management and stroke prevention. CASE PRESENTATION: We present the case of an 84-year-old Italian woman with a left atrial appendage thrombus that developed despite her use of anticoagulant therapy with warfarin for a previous pulmonary embolism. She had atrial fibrillation and heterozygosity for both factor V Leiden and methylenetetrahydrofolate reductase C677T mutation, thus creating resistance to activated protein C...

The incidence of acute myocardial infarction (AMI) increases with clustering of predisposing risk factors. In younger subjects with a positive family history of AMI occurring in relatives under the age of 60 years without obvious risk factors for atherosclerosis, there is a potential for strong inherited traits contributing to the risk of coronary disease. Among them there is increasing evidence that hereditary thrombophilia may play a major role. We present a unique case of a patient developing AMI at the age of 48 years...
