OBJECTIVE: Pulmonary CT angiography (CTA) is the imaging modality of choice in suspected acute pulmonary embolism (PE). Current pulmonary CTA techniques involve ever lower doses of contrast medium and radiation along with advanced postprocessing applications to enhance image quality, diagnostic accuracy, and provide added value in patient management. The objective of this article is to summarize these current developments and discuss the appropriate use of state-of-the-art pulmonary CTA...

REVIEW
William M Sherk, Jadranka Stojanovska
OBJECTIVE: The purpose of this article is to describe the importance of clinical decision rules for pretest assessment of the probability of the presence of pulmonary embolism (PE), the effect of use of the rules on the yield of pulmonary CT angiography, and obstacles to implementation of the rules in clinical practice. CONCLUSION: Pulmonary CT angiography is the imaging modality of choice for evaluating patients with suspected PE. Despite increased use of pulmonary CTA, the diagnostic yield for PE remains low...

#3
REVIEW
Victor Chiu, Casey O'Connell
OBJECTIVE: The incidental pulmonary embolism (PE) is being identified at an increasing rate because of use of MDCT and presents a management challenge because of a lack of prospective data. Most clinicians treat patients with proximal or segmental incidental PE in the same manner as patients with suspected PE. CONCLUSION: The treatment of subsegmental PE may be guided by an assessment of patient symptoms, risk factors for recurrent venous thrombosis, and concomitant deep venous thrombosis...

REVIEW
Darlene Metter, Mark Tulchinsky, Leonard M Freeman
OBJECTIVE: The purpose of this article is to outline recent progress made in ventilation-perfusion (V/Q) scintigraphy imaging techniques and the interpretation systems used for the diagnosis of pulmonary embolism (PE). Various state-of-the-art approaches that can be selected according to the needs dictated by the medical practice environment and specific patient groups are presented. CONCLUSION: Although advances in tomographic imaging have certainly improved the sensitivity of V/Q scans for the diagnosis of PE, they may lead to overdiagnosis by revealing small and clinically insignificant PEs...

Harish Jarrett, Riyaz Bashir
OBJECTIVE: The purpose of this article is to describe the indications for and approach to catheter-based treatment of acute venous thromboembolism (VTE). CONCLUSION: Catheter-based treatment of VTE is a viable adjunct to anticoagulant therapy and is being rapidly adopted around the United States. Early data suggest that these therapies reduce postthrombotic sequelae and improve quality of life, but bleeding events are still frequent, particularly at low-volume centers...

Asthma is associated with an increased risk of pulmonary embolism (PE) but little is known about whether asthma is associated with an increased risk of deep venous thrombosis (DVT). The aim in this study was to determine the risk of the first event of PE, DVT or a combination of PE and DVT in patients with asthma.We conducted this nationwide case-control study using data from Swedish nationwide registries. We included 114 366 Swedish-born patients with a first hospital diagnosis of PE, 76 494 patients with DVT and 6854 patients with both PE and DVT in Sweden between 1981 and 2010...

REVIEW
Helia Robert-Ebadi, Marc Righini
Isolated distal deep vein thrombosis (DVT), also known as calf DVT, represents up to 50% of all lower limb DVT in ultrasound series and is therefore a frequent medical condition. Unlike proximal DVT and pulmonary embolism (PE), which have been extensively studied and for which management is well standardized, much less is known on the optimal management of isolated calf DVT. Recent data arising from registries and non-randomized studies suggest that most distal DVTs do not extend to the proximal veins and have an uneventful follow-up when left untreated...

Venous thromboembolism (VTE) is a significant health problem in the general population but especially in cancer patients. In this review, we discuss the epidemiology and burden of the disease, the pathophysiology of cancer-associated VTE, and the clinical treatment options for both primary prevention and acute treatment. Overall, the development of VTE in cancer patients is related to increases in morbidity, mortality, and medical costs. However, the incidence of cancer-associated VTE varies due to patient-related factors (e...

PURPOSE OF REVIEW: Venous thromboembolism is frequent in chronic myeloproliferative neoplasms (MPN). The current strategy for its management includes cytoreductive therapy and antithrombotic prophylaxis, but many issues remain uncertain. In this review, the risk factors and prevention of recurrences will be discussed. RECENT FINDINGS: Around one-third of patients with polycythemia vera and essential thrombocythemia experience a major thrombosis at diagnosis or during follow-up...

PURPOSE OF REVIEW: The majority of evidence on the safety and efficacy of oral anticoagulation for stroke prevention amongst patients with atrial fibrillation is derived from those without significant valvular heart disease. This article will review current knowledge, areas of uncertainty and controversy, and ongoing research on oral anticoagulation for stroke prevention amongst patients with valvular heart disease. RECENT FINDINGS: The rates of stroke, systemic embolism, and major bleeding were similar for patients with and without significant native valvular disease when treated with direct oral anticoagulants (DOACs) or vitamin K antagonists...

REVIEW
Noémie Despas, Anne-Sophie Larock, Hugues Jacqmin, Jonathan Douxfils, Bernard Chatelain, Marc Chatelain, François Mullier
Traditional anticoagulant agents such as unfractionated heparin (UFH), low molecular weight heparins (LMWHs), fondaparinux, danaparoid and bivalirudine are used in the prevention and treatment of thromboembolic diseases. However, these agents have limitations: their constraining parenteral route of administration and the need for regular coagulation monitoring for HNF. The LMWHs, with their more predictable anticoagulant response, don't require a systematic monitoring. The usefulness of LMWHs monitoring in several clinical situations such as pregnancy, obesity and renal insufficiency is a matter of debate...

Atrial fibrillation and venous thromboembolism (VTE) are common disorders associated with maleficent thrombotic events, particularly in the elderly patients. Polypharmacy, co-morbidities, and altered pharmacokinetics, often present in these patients, render the use of anticoagulants quite challenging. Novel oral anticoagulants (NOACs) have recently emerged as alternatives to Vitamin K Antagonists (VKAs) and are gradually increasing their popularity mainly because of their fewer drug and food interactions and ease of use...

REVIEW

Thrombotic episodes are far less common than bleeding complications after hematopoietic stem cell transplantation (HSCT). However, they lead to significant morbidity and mortality. These complications are classified into four groups, including venous thromboembolic events (VTE), catheter-induced thrombosis (CIT), transplant-associated thrombotic microangiopathy (TA-TMA) and sinusoidal obstruction syndrome (SOS) or veno-occlusive disease (VOD). The frequency of VTE is increased among patients undergoing HSCT due to some acquired conditions including underlying malignancy, infections, administration of myeloablative conditioning regimens and/or total body irradiation, prolonged hospitalizations leading to immobility and presence of central venous catheters...

BACKGROUND: Even though clinical data support a relation between ischemic stroke and venous thromboembolism (VTE), the strength and time dependence of the association remain to be settled at the population level. We therefore aimed to investigate the association between ischemic stroke and VTE in a prospective population-based cohort. METHODS AND RESULTS: Participants (n=30 002) were recruited from 3 surveys of the Tromsø study (conducted in 1994-1995, 2001, and 2007-2008) and followed through 2010...

We sought to compare length-of-stay (LOS), total hospital costs, and readmissions among pulmonary embolism (PE) patients treated with rivaroxaban versus parenterally bridged warfarin. We identified adult PE (primary diagnostic code = 415.1x) patients in the Premier Database (11/2012-9/2015), and included those with ≥1 PE diagnostic test on days 0-2. Rivaroxaban users (allowing ≤2 days of prior parenteral therapy) were 1:1 propensity score matched to patients parenterally bridged to warfarin. LOS, total costs, and readmission for venous thromboembolism (VTE) or major bleeding within the same or subsequent 2 months were compared between cohorts...
