Amniotic fluid embolism is a rare but often catastrophic emergency. The non-specific clinical features and lack of diagnostic tests make it a diagnosis of exclusion. Point-of-care visco-elastometric testing is being increasingly used during obstetric haemorrhage. We present a case of amniotic fluid embolism, diagnosed and managed using rotational thromboelastography. During a precipitous labour, a 21-year-old multiparous woman became pale, distressed and disorientated. The fetus was delivered using forceps...

BACKGROUND: The methodology of thromboprophylaxis post minimally invasive esophagectomy (MIE) is unclear. Thus, we compared the efficacy and safety of fondaparinux and nadroparin on the prophylaxis of venous thromboembolism (VTE) after MIE. MATERIALS AND METHODS: We conducted a randomized, double-blind, treatment-controlled study. Consecutive patients undergoing MIE randomly received a single dose of either nadroparin 2850 AxaIU (Group H) or fondaparinux 2.5 mg (Group F) daily...

Changes in systemic redox balance can alter platelet activation and aggregation. Acute pulmonary embolism (PE) is a systematic inflammatory disease associated with mechanical shear stress, increased thrombin, catecholamines, serotonin and hemolysis, which cumulatively can hyperactivate platelets and accelerate their turnover. We tested the hypothesis that platelets from patients with moderately severe PE will show hyperstimulation and a pre-apoptotic phenotype associated with microparticles (MPs) in plasma...

Deep venous thromboembolism and pulmonary embolism are still underdiagnosed in the ICU. Thromboelastography (TEG) has shown considerable variability in sensitivity and specificity as a predictor of venous thromboembolism (VTE). We designed a prospective double-blind observational study to predict the risk of VTE using TEG in a cohort of critically ill patients. Seventy-two hours after admission in the ICU and consequent prophylaxis with low-molecular-weight heparin, we performed compressive color-Doppler ultrasound and diagnosed deep venous thrombosis...

BACKGROUND: We examine the clinical significance and biomarkers of tissue plasminogen activator (tPA)-catalyzed clot lysis time (CLT) in patients with intermediate-risk pulmonary embolism (PE). METHODS: Platelet-poor, citrated plasma was obtained from patients with PE. Healthy age- and sex-matched patients served as disease-negative controls. Fibrinogen, α2-antiplasmin, plasminogen, thrombin activatable fibrinolysis inhibitor (TAFI), plasminogen activator Inhibitor 1 (PAI-1), thrombin time and D-dimer were quantified...

BACKGROUND: Recent studies using thromboelastography indicate that patients are at risk for hypercoagulability early after injury. Pulmonary embolism (PE) is also well known to cause significant morbidity and mortality after injury and can occur within 72 hours of admission (early PE). Despite this risk, prophylactic anticoagulation is often delayed in patients with certain injuries due to concerns about bleeding. STUDY DESIGN: This was a retrospective study of injured patients with a PE from 2007 to 2013 at 3 level I trauma centers...

INTRODUCTION: Thromboembolic complications contribute substantially to perioperative morbidity and mortality. Routine laboratory tests do not detect patients with acquired or congenital hypercoagulability who may be at increased risk of perioperative thromboembolism. Rotational thromboelastometry (ROTEM) is a digitized modification of conventional thromboelastography that is stable and technically easy to use. We designed a prospective observational study to evaluate whether preoperative ROTEM can identify patients at increased risk for postoperative thromboembolic complications after major non-cardiac surgery...

BACKGROUND: Central venous catheters (CVCs) increase the risk of venous thromboembolism. We have previously demonstrated that pulmonary artery catheters are associated with a hypercoagulable state in an animal model and in patients. The purpose of this study is to determine whether the insertion of a CVC is associated with a similar response. METHODS: HASH(0x302fad0) ANIMAL: 7F femoral artery catheters were placed in healthy anesthetized swine (N = 16)...

Pulmonary thromboembolism (PTE) has been associated with many diseases. Clot formation is a consequence of hypercoagulability, blood stasis, and damage to the endothelium of blood vessels, a set of changes known as the Virchow triad. Diagnosing PTE may be difficult because common clinical signs, including tachypnea, dyspnea, and hypoxemia, are not pathognomonic for the disease. The initial workup for PTE should include arterial blood gas analysis and thoracic radiography. If there is a strong clinical suspicion for PTE, further tests are indicated, such as D-dimer measurement, thromboelastography, and advanced imaging...

Microvascular reconstructive surgery has seen a revival with the introduction of muscle-sparing perforator flaps. Recognition of potential ethnic differences in coagulation profiles would be important to a microvascular surgeon. Based on clinical observations, we hypothesize that Asian patients have a less thrombogenic coagulation profile than Caucasians. An extensive retrospective review was performed. The annual incidence of venous thromboembolism in the United States is generally accepted to range from 70 to 120 events per 100,000 people versus 16 to 17 events per 100,000 persons in Asia...

BACKGROUND AND OBJECTIVE: Despite clinical and laboratory evidence of perioperative hypercoagulability, alterations in haemostasis after potentially haemorrhagic oncologic surgery are difficult to predict. This study aims to evaluate the entity, the extent and the duration of perioperative coagulative alterations following pancreas and liver oncologic surgery, by the use of both routine tests and thromboelastogram (TEG). METHODS: Fifty-six patients undergoing liver (n = 38) and pancreatic (n = 18) surgery were studied...

OBJECTIVES: To investigate the hemostatic status of critically ill, nonbleeding trauma patients. We hypothesized that a hypercoagulable state exists in patients early after severe injury and that the pattern of clotting and fibrinolysis are similar between burned and nonburn trauma patients. MATERIALS: Patients admitted to the surgical or burn intensive care unit within 24 hours after injury were enrolled. Blood samples were drawn on days 0 through 7. Laboratory tests included prothrombin time (PT), activated partial thromboplastin time (aPTT), levels of activated factor XI, D-dimer, protein C percent activity, antithrombin III percent activity, and thromboelastography (TEG)...

Orthotopic liver transplantation (OLT) is one of the most demanding surgical procedures performed. Intraoperative bleeding can be substantial and related to both surgical and nonsurgical causes. A less common but previously reported phenomenon is intraoperative cardiopulmonary thromboembolism precipitating major patient morbidity and mortality. In this paper, we present four cases of intraoperative thromboembolism during OLT. These cases were performed without the concomitant use of antifibrinolytic drugs. We performed a review and analysis of previously reported cases of intraoperative thromboembolism during OLT...
