Venous thromboembolism (VTE) includes deep vein thrombosis and pulmonary embolism, and a combination of environmental and genetic risk factors contributes to VTE risk. Within environmental risk factors, some are provoking (e.g., cancer, surgery, trauma or fracture, immobilization, pregnancy and the postpartum period, long-distance travel, hospitalization, catheterization, and acute infection) and others are nonprovoking (e.g., age, sex, race/ethnicity, body mass index and obesity, oral contraceptive or hormone therapy use, corticosteroid use, statin use, diet, physical activity, sedentary time, and air pollution)...

We describe a case of fulminant intraoperative thrombosis during deceased donor liver transplantation. Despite significant medical bleeding, the patient suddenly developed diffuse thrombosis in all chambers of the heart and pulmonary vasculature resulting in intraoperative death. The patient's postmortem genetic analysis demonstrated a deleterious missense mutation in a coagulation pathway gene, SERPINC1, which codes for antithrombin III. The level of antithrombin III was not available to directly prove the causality of thrombosis, but our findings suggest that this mutation, in combination with antifibrinolytic administration in a hypercoagulable cirrhotic patient, might have contributed to the development of this catastrophic thrombotic event...

BACKGROUND: Cervical artery dissection (CAD) is a leading cause of stroke among middle-aged adults, but the etiology is unclear. Some reports of seasonal variation in CAD incidence have been suggested but may reflect extreme climatic conditions. Seasonal variation may implicate more transient seasonal causes such as proinflammatory or hypercoagulable states. This study aimed to assess whether CAD incidence varied with season between UK and Australian sites. Also, this study aimed to determine whether there was a different pattern of seasonal variation between arteries (carotid and vertebral) and any association between CAD incidence and clinical factors...

Thrombophilia or hypercoagulable conditions can be thought of as either inherited or acquired. The inherited disorders include deficiencies of antithrombin, protein C, or protein S or the common disorders of factor V Leiden and prothrombin G20210A gene mutation. All these disorders are inherited as autosomal dominant and predispose individuals primarily to venous thrombosis. Acquired thrombophilic conditions are seen in individuals with cancer, phospholipid antibodies, and a whole host of other conditions that alter endothelial function, change blood levels of coagulant or anticoagulant proteins, activate platelets, or have other effects on coagulation proteins, platelet function, or the endothelium...

There are multiple systemic diseases that have an impact on coagulation, of which oral and maxillofacial surgeons must be cognizant. Recent evidence has supported the potential for both hypocoagulable and hypercoagulable states in patients with liver and kidney disease with an even less understood impact on prolonged bleeding in the oral cavity. These systemic diseases are not limited to diseases affecting the liver, kidney, and bone marrow; however, these diseases are common among the patient population and surgeons must be capable of making appropriate judgment and modifying care appropriately...

Idiopathic or unprovoked venous thromboembolism is an event occurring in the absence of any apparent provoking or triggering environmental risk factors, such as surgery, trauma, and immobilization. Areas covered: Unprovoked VTE can be associated with occult cancer, but only limited, and not extensive cancer screening, may be warranted, as the rate of occult cancer is low in such patients. Routine thrombophilia testing is not currently recommended as it does not influence the management of the disease. The duration of anticoagulation for unprovoked VTE after the first three months is still debated as the disease tends to recur regardless of treatment duration...

Pregnancy is associated with a hypercoagulable state. Women requiring anticoagulation need careful attention throughout pregnancy and the post-partum period. The choice of anticoagulant therapy, the degree of monitoring, and the therapeutic target should be modulated by balancing the risks and the benefits to the mother and fetus. Many of the available anticoagulant agents may be used safely in pregnancy, but they are disadvantaged by competing efficacy and risks to the mother and fetus. For example, vitamin K antagonists are the most efficacious for preventing mechanical valve thrombosis, but they pose risks to the fetus...

BACKGROUND: Patients with thalassaemia may have thromboembolic events and, even without thrombosis, they have a subclinical hypercoagulable state. In this setting, several coagulation laboratory abnormalities have been described, but thus far no studies have explored the contribution of platelet adhesive and procoagulant properties to blood clotting activation. In this study, we dissected the platelet procoagulant effect and influence of blood transfusions on haemostasis and platelet function in thalassaemic patients...

Background: The etiology of multifocal osteonecrosis is not definitively known; however, hypercoagulable state is a very plausible cause. Methods: We present an unusual case of a 12-year-old boy with a history of Legg-Calve-Perthes disease presenting with right wrist pain who was subsequently diagnosed with Kienbock's disease. The finding of multifocal osteonecrosis prompted testing for a hypercoagulable state that was positive for Factor V Leiden thrombophilia. A thorough literature review using Medline database was conducted to investigate associations between inherited hypercoagulable states and multifocal osteonecrosis...

Hypercoagulable state in Mendelian Susceptibility to Mycobacterium Disease (MSMD) patients who are prone to mycobacterium infection has been established in a few studies and thrombosis considered as a rare. In a case-control study, the prevalence of factor V Leiden (FVL), Prothrombin (PTH) G20210A and Methylenetetrahydrofolate Reductase (MTHFR) C677T, A1298C mutations, were investigated among mycobacterium infected patients. The study were compromised 30 patients with mycobacterium infections (Invasive, disseminated and/ or recurrent infections with Bacille Calmette-Guerin (BCG) or non Tuberculosis Mycobacterium (NTM) and Mycobacterium Tuberculosis (MTB), with positive result for Acid Fast Bacilli (AFB), and Tuberculin skin test (TST)) and 30 normal healthy controls...

BACKGROUND: Non-bacterial thrombotic endocarditis (NBTE) is an uncommon pathological situation, which involves the presence of bland, fibrin-platelet thrombi. It usually occurs at the endocardium of cardiac valves, in association with endothelial injury and a hypercoagulative state. However, NBTE on the endocardium at the right atrial free wall in a patient without any apparent hypercoagulative background is rarely reported. CASE PRESENTATION: A girl aged 4 years with severe pectus excavatum was referred to our hospital for treatment of a recurrent right atrial tumor...

Adventitial cystic disease (ACD) of the common femoral vein is a rare vascular disorder. It becomes more difficult to recognize preoperatively especially when the femoral vein is affected. We report the case of a 62-year-old female patient who presented with a one-month history of painless swelling in her right lower extremity. She had no specific past medical history and no history of trauma, and had a full coagulopathy profile that was negative for any hypercoagulable syndrome. On examination, her lower right leg was significantly swollen with a palpable mass in her right inguinal region...

OBJECTIVE: Thalassemia is a heterogeneous group of congenital hemoglobinopathies caused by mutations in the globin gene complex that result in an unbalanced globin synthesis. Unmatched globin chains bind to the cytosolic surface of red blood cell membrane where they cause oxidative damage that might in part be responsible for membrane weakness. The deformability of red blood cells and hypercoagulable state in thalassemic patients have been incriminated in leg ulcer formation, as this might cause ischemia to the skin and consequently friability and ulceration...

: Incidence of venous thromboembolism (VTE) in adult trauma patients is high despite mechanical and pharmacologic prophylaxis. We hypothesized that thrombin formation capacity as measured by calibrated automated thrombogram (CAT) is increased early in hospitalization and is associated with the development of VTE. METHODS: We conducted a prospective study in adult, critically ill trauma patients. Plasma was generated from whole blood samples collected within the first 3days of hospital admission...

Sickle cell disease is a single point mutation disease that is known to alter the coagulation system, leading to hypercoagulable plasma conditions. These hypercoagulable conditions can lead to complications in the vasculature, caused by fibrin clots that form undesirably. There is a need to understand the morphology and structure of fibrin clots from patients with sickle cell disease, as this could lead to further discovery of treatments and life-saving therapies. In this work, a computational imaging analysis method is presented to evaluate fibrin agglomeration in the presence of erythrocytes (RBCs) homozygous for the sickle cell mutation (SS)...

The analysis of the influence of the intra-abdominal hypertension on the blood coagulation system by carrying out an experimental research with laboratory animals is presented in article. After simulating intra-abdominal hypertension with different degree and exposition we made the laboratory research of blood coagulation system (fibrinogen, PTI, SFMC, APTT) and ELISA research on the concentration of the modern marker of thrombozis - D-dimer. The results in article clearly demonstrate that there is a direct linear dependence of level of fibrinogen and SFMC on degree of intra-abdominal hypertension, and the multidirectional changes of indicators with increase of intra-abdominal hypertension duration - towards hypercoagulation for 3-12 hours, and then by 24 o'clock - in the opposite direction towards hypocoagulation...
