BACKGROUND: Bariatric surgery is associated with increased thromboembolic risk, which may extend well beyond hospital stay. The hemostatic mechanisms implicated in this risk are not well established. OBJECTIVES: We aimed to determine the dynamics of hemostatic changes and procoagulant potential among patients undergoing laparoscopic sleeve gastrectomy, during both the early and late postoperative periods. SETTING: A university hospital. METHODS: Patients who underwent laparoscopic sleeve gastrectomy were recruited consecutively to this study...

INTRODUCTION: The prevalence and impact of hypercoagulability (hypo) in severely injured patients early after injury remains unclear. We hypothesize that the predominant phenotype of postinjury coagulopathy is hypercoagulability (hyper) and it is associated with increased mortality. MATERIAL AND METHODS: Blood samples from 141 healthy volunteers assayed with thrombelastography (TEG) were used to identify thresholds of hypo and hypercoagulability (above 95th/below the 5(th)percentile) in four TEG indices...

Increases in prothrombin time (PT) and international normalised ratio (INR) characterise acute liver injury (ALI) and failure (ALF), yet a wide heterogeneity in clotting abnormalities exists. This study defines evolution of coagulopathy in 10 pigs with acetaminophen (APAP)-induced ALI compared to 3 Controls. APAP administration began at 0 h and continued to 'ALF', defined as INR >3. In APAP pigs, INR was 1.05 ± 0.02 at 0 h, 2.15 ± 0.43 at 16 h and > 3 at 18 ± 1 h. At 12 h thromboelastography (TEG) demonstrated increased clot formation rate, associated with portal vein platelet aggregates and reductions in protein C, protein S, antithrombin and A Disintegrin and Metalloprotease with Thrombospondin type 1 repeats-13 (ADAMTS-13) to 60%, 24%, 47% and 32% normal respectively...

We enrolled 62 consecutive patients with advanced stage cancers and venous thromboembolism (VTE), prospectively followed until 1 year. All patients received 6 month low-molecular-weight heparin (LMWH) therapy. We evaluated thrombin generation (TG) and D-dimer levels at different time points, to determine whether they were sensitive to LMWH and explore a possible association with VTE recurrence, bleeding, and overall survival. During LMWH, levels of TG and D-dimer significantly dropped. No VTE recurrences occurred, one patient had cancer-related intestinal hemorrhage...

BACKGROUND: The study's purpose was to determine if there is an association between ABO blood group and the development of symptomatic venous thromboembolism (VTE) after total joint arthroplasty (TJA). METHODS: A total of 28,025 patients who underwent primary TJA at a single health care system from 2000 to 2014 were retrospectively reviewed from electronic records. Patients who experienced a symptomatic VTE were identified. A multivariate regression model adjusted for known potential risk factors, including age, gender, body mass index, surgery type, previous VTE, smokers, rheumatologic diseases, malignancy, hypercoagulable state, and VTE prophylaxis, was developed to test the association of ABO blood group and postoperative VTE...

BACKGROUND: Blood coagulation plays a crucial role in the blastocyst implantation process and its alteration may be related to in vitro fertilization (IVF) failure. We conducted a prospective observational longitudinal study in women eligible for IVF to explore the association between alterations of coagulation with the IVF outcome and to identify the biomarkers of hypercoagulability which are related with this outcome. METHODS: Thirty-eight women eligible for IVF (IVF-group) and 30 healthy, age-matched women (control group) were included...

BACKGROUND AND PURPOSE: Patients with active cancer are at an increased risk for stroke. Hypercoagulability plays an important role in cancer-related stroke. We aimed to test whether 1) hypercoagulability is a predictor of survival, and 2) correction of the hypercoagulable state leads to better survival in patients with stroke and active cancer. METHODS: We recruited consecutive patients with acute ischemic stroke and active systemic cancer between January 2006 and July 2015...

BACKGROUND: The mechanism for hypercoagulability in malignancy is not entirely understood. Although several studies report contrasting finding about the link between elevated plasma levels of the lipoprotein(a) [Lp(a)] and the possible recurrence of venous thromboembolism, we perform a study to evaluate the impact of the Lp(a) in the development of portal vein thromboembolism (PVT) in patients with HCC. METHODS: We compared 44 PVT patients with 50 healthy subjects and 50 HCC patients...

BACKGROUND AND PURPOSE: The occurrence of stroke in cancer patients is caused by conventional vascular risk factors and cancer-specific mechanisms. However, cryptogenic stroke in patients with cancer was considered to be more related to cancer-specific hypercoagulability. In this study, we investigated the potential of the D-dimer level to serve as a predictor of early neurologic deterioration (END) in cryptogenic stroke patients with active cancer. METHODS: We recruited 109 cryptogenic stroke patients with active cancer within 72 h of symptom onset...

BACKGROUND: Diabetes mellitus (DM) is a hypercoagulable state and is associated with highly increased risk of vascular complications. In the theory of traditional Chinese medicine (TCM), these vascular complications are classified as blood stasis. Diagnosis of the tongue plays an important role in TCM; a bluish tongue, petechiae, and engorged sublingual collateral vessels are manifestations of blood stasis. This study aimed to characterize the tongue manifestations of blood stasis and derive a relationship between blood stasis and vascular disorders in patients with type 2 DM...

INTRODUCTION: Patients with an unruptured intracranial aneurysm treated with coil embolization are routinely admitted to the intensive care unit (ICU) after the procedure; however, this practice is questionable. The purpose of this study was to determine if routine admission to the ICU is necessary for patients undergoing coil embolization of an unruptured intracranial aneurysm. METHODS: We conducted a retrospective cohort study of all patients undergoing elective endovascular treatment of an unruptured intracranial aneurysm between 2005 and 2012 at our institution...

BACKGROUND & AIMS: Several lines of evidence suggest that the hemostatic disorders of cirrhosis may have a significant clinical impact. We investigated the independent predictive value of components of the hemostatic system on the occurrence of ascites, variceal bleeding (VB), and survival. METHODS: One hundred and two patients with thrombocytopenia (Child-Pugh class A/B/C: 34/34/34) were enrolled. Platelet counts, factors (F) II, V, VII, and VIII, antithrombin, protein C (PC), FVIII-to-PC ratio as an index of procoagulant imbalance, von Willebrand factor antigen (vWF-Ag), and model for end-stage liver disease (MELD) were evaluated...
