INTRODUCTION: Deep vein thrombosis (DVT) continues to be a significant source of morbidity for surgical patients. Placement of a retrievable inferior vena cava (IVC) filter is used when patients have contraindications to anticoagulation or recurrent pulmonary embolism despite therapeutic anticoagulation. Although retrievable IVC filters are often used, they carry a unique set of risks. PRESENTATION OF CASE: A 67-year-old man presents to the Emergency Room (ER) following large volume melena and complaining of syncope...

BACKGROUND: Preoperative risk stratification is a critical element in assessing the risks and benefits of surgery. Prior work has demonstrated that intra-abdominal general surgery patients can be classified based on their comorbidities and risk factors using latent class analysis (LCA), a model-based clustering technique designed to find groups of patients that are similar with respect to characteristics entered into the model. Moreover, the latent risk classes were predictive of 30-day mortality...

Given the high incidence of deep vein thrombosis/pulmonary embolism (DVT/PE) (300,000 to 600,000 per year in the U.S.) and the 30 percent mortality rate associated with undiagnosed PE, diagnostic evaluation is very important. One of the tools used to evaluate for DVT and PE is D-dimer testing. A negative D-dimer test, along with a low Wells clinical probability score, can safely rule out DVT/PE without the need for additional imaging. This approach can reduce cost; however, D-dimer testing is not indicated in all patients...

Soma Mohammed, Emmanuel J Favaloro
Activated protein C resistance (APCR) describes a hemostatic disorder characterized by a poor anticoagulant response to activated protein C (APC). This results in an increased risk of venous thrombosis, including deep vein thrombosis and pulmonary embolism. Protein C is a natural anticoagulant that is synthesized in the liver and is activated to APC via proteolysis. APC then degrades Factors Va and VIIIa. APCR describes the reduced inability of APC to cleave Factors Va and VIIIa, which therefore promotes increased thrombin generation and potentially leads to a prothrombotic state...

Venous thromboembolism, usually entailing deep vein thrombosis, pulmonary embolism, or both, is a complex and multifactorial disorder, in which a number of putative conditions interplay and finally contribute to propel the individual risk over a certain degree, so ultimately culminating in the development of venous occlusive disorders. Thrombophilia is commonly defined as a propensity to develop venous thromboembolism on the basis of an underlying hypercoagulable state attributable to inherited or acquired disorders of blood coagulation or fibrinolysis...

Cerebral embolism originating from intracardiac tumors represents a rare cause of stroke and has been documented in both adult and pediatric populations. We present a patient recently diagnosed with a right pulmonary hilum tumor, invading the pulmonary veins and the left atrium. Two consecutive episodes of large cerebral vessel occlusion in separate vascular territories occurred in the same day and were treated by mechanical thrombectomy. Embolic material retrieved on both occasions contained tumor fragments with peripheral endothelialization...

BACKGROUND: Our aim was to develop a model of acute right heart failure (ARHF) in the setting of pulmonary hypertension and to characterize acute right ventricular lesions that develop early after hemodynamic restoration. METHODS AND RESULTS: We used a described piglet model of chronic pulmonary hypertension (cPH) induced by pulmonary artery occlusions. We induced ARHF in animals with cPH (ARHF-cPH group, n=9) by volume loading and iterative acute pulmonary embolisms until hemodynamic compromise followed by dobutamine infusion for hemodynamic restoration prior to sacrifice for right ventricular tissue evaluation...

Venous thromboembolism (VTE) remains a leading cause of direct maternal deaths in the developed countries. The incidence of VTE has increased significantly during the past two decades. The absolute risk of VTE is estimated 0.6-2.2 per 1000 deliveries. Compared with age-matched non-pregnant women, the daily risk of VTE is increased 7- to 10-fold for antepartum VTE, but it is 15- to 35-fold for postpartum VTE. The incidence of pulmonary embolism (PE) during the first 6 weeks postpartum is nearly 15-fold higher compared to the incidence in pregnancy, and remains significantly increased up to 12 weeks postpartum...

This study evaluates whether immature platelets (IPF) determined in the post anesthesia care unit (PACU) can predict major adverse cardiovascular events (MACE) or other thromboembolic events after intermediate and high-risk surgery. IPF are increased in patients with acute coronary syndrome and recently gained interest as novel biomarker for risk stratification. In this prospective observational trial 732 patients undergoing intermediate or high-risk non-cardiac surgery were enrolled (NCT02097602). IPF was measured preoperatively and postoperatively in the PACU...
