Patients with overgrowth and complex vascular malformation syndromes, including Proteus syndrome have an increased risk of thromboembolism. Proteus syndrome is a mosaic, progressive overgrowth disorder involving vasculature, skin, and skeleton, and caused by a somatic activating mutation in AKT1. We conducted a comprehensive review of the medical histories and hematologic evaluations of 57 patients with Proteus syndrome to identify potential risk factors for thrombosis. We found that six of ten patients, who were deceased, died secondary to deep venous thrombosis and/or pulmonary embolism...

BACKGROUND: Identifying and treating the cause of pulmonary symptoms in HIV patients with underlying systemic lupus erythematosus (SLE) can be very challenging. Delays in diagnosing active SLE in HIV patients can lead to significant morbidity and even mortality. We report the case of an HIV-positive woman with SLE who presented with severe respiratory distress. CASE PRESENTATION: A 42-year-old HIV-positive woman presented with a 7-month history of anorexia, progressive dyspnoea, and a productive cough...

PURPOSE: Recurrence is a major clinical problem in patients with pulmonary embolism and can affect mortality. The decision to discontinue treatment is important for recurrence and is based on patients' clinical features as well as certain blood parameters. Our aim in this study was to evaluate whether mean platelet volume (MPV) and platelet distribution width (PDW) have utility as new predictive parameters for recurrence and mortality in pulmonary embolism. MATERIALS AND METHODS: A total of 440 patients with pulmonary embolism underwent computed tomography, Doppler ultrasonography, and echocardiography before and at the conclusion of treatment...

Upper extremity deep vein thrombosis (UEDVT) accounts for 4% to 10% of all cases of deep vein thrombosis. UEDVT may present with localized pain, erythema, and swelling of the arm, but may also be detected incidentally by diagnostic imaging tests performed for other reasons. Prompt and accurate diagnosis is crucial to prevent pulmonary embolism and long-term complications as the post-thrombotic syndrome of the arm. Unlike the diagnostic management of deep vein thrombosis (DVT) of the lower extremities, which is well established, the work-up of patients with clinically suspected UEDVT remains uncertain with limited evidence from studies of small size and poor methodological quality...

BACKGROUND: Tumor markers (TMs) and D-Dimer are both hallmarks of severity and prognosis of lung cancer. Tumor markers could be related to pulmonary embolism (PE) in lung cancer. RESULTS: The number of abnormal tumor markers of lung cancer patients with pulmonary embolism (3.9 ± 1.1vs1.6 ± 0.6,P 0.005) was more than that in patients without pulmonary embolism. TMs panel (P trend < 0.001), CEA (R2 0.735, P0.003) and CYFRA21-1 (R2 0.718, P0.005) were positively correlated with D-Dimer in patients with pulmonary embolism...

A normal computed tomography pulmonary angiography (CTPA) remains a controversial criterion for ruling out acute pulmonary embolism (PE) in patients with a likely clinical probability. We set out to determine the risk of VTE and fatal PE after a normal CTPA in this patient category and compare these risk to those after a normal pulmonary angiogram of 1.7 % (95 %CI 1.0-2.7 %) and 0.3 % (95 %CI 0.02-0.7 %). A patient-level meta-analysis from 4 prospective diagnostic management studies that sequentially applied the Wells rule, D-dimer tests and CTPA to consecutive patients with clinically suspected acute PE...

Venous thromboembolism (VTE) includes deep venous thrombosis (DVT) and pulmonary embolism (PE). The clinical presentation of VTE is nonspecific and requires confirmatory testing. The most common diagnostic tool for DVT is duplex ultrasonography since it is a noninvasive test with high accuracy. Contrast venography is considered the gold standard modality to diagnose DVT, but it is an invasive test. Magnetic resonance venography and computed tomography venography are alternative diagnostic methods for DVT, which can be helpful in certain circumstances...

BACKGROUND: Validated diagnostic algorithms in patients with suspected pulmonary embolism are often not used correctly or only benefit subgroups of patients, leading to overuse of computed tomography pulmonary angiography (CTPA). The YEARS clinical decision rule that incorporates differential D-dimer cutoff values at presentation, has been developed to be fast, to be compatible with clinical practice, and to reduce the number of CTPA investigations in all age groups. We aimed to prospectively evaluate this novel and simplified diagnostic algorithm for suspected acute pulmonary embolism...

BACKGROUND: Whether post-anticoagulation D-dimer levels are useful in predicting recurrence in elderly patients with unprovoked venous thromboembolism is unknown. METHODS: We followed up 157 patients aged ≥65 years with acute symptomatic, unprovoked venous thromboembolism in a prospective, multicenter cohort study. All patients completed 3-12 months of anticoagulation and then underwent quantitative D-dimer testing (enzyme-linked immunosorbent assay) 12 months after the index venous thromboembolism...

The purpose was to determine whether young women in the emergency department who received computed tomographic (CT) pulmonary angiograms were evaluated to receive lower dose imaging or no imaging, recognizing that the risks of radiation are particularly high in young women. This was a retrospective cohort investigation of women aged 18 to 29 years seen for suspected acute pulmonary embolism in emergency departments of 5 regional hospitals from May 1, 2015 to April 30, 2016. Computed tomographic (CT) pulmonary angiograms were obtained in 379 young women...

Patients with reduced cardiac function are thought to have a higher risk of venous thromboembolism (VTE). Additionally, they are vulnerable to complications of pulmonary embolism (PE) as well as right heart failure (HF), which in return is supposed to increase the rate of mortality. Studies focusing on VTE in heart failure patients were rare in Asian countries before the 21st century. Nowadays, more and more data are becoming available in this field in Asia. It is already known that heart failure can increase the risk of VTE, but so far a consensus on this issue has not been reached for many years, not only in Asian countries but all over the world...

D-dimer assays are commonly used in clinical practice to exclude a diagnosis of deep vein thrombosis or pulmonary embolism. More recently, they have been also been used to guide patients with unprovoked venous thromboembolism (VTE) when faced with the decision to continue or stop anticoagulation after initial treatment is complete. D-dimer assays vary widely with respect to the antibody used, method of capture, instrumentation required, and calibration standard. These differences have an important influence on the operating characteristics of the assays...

OBJECTIVES: Pulmonary embolism (PE) is seven times more common in cancer patients than non-cancer patients. Since the existing clinical prediction rules (CPRs) were validated predominantly in a non-cancer population, we decided to look at the utility of arterial blood gas (ABG) analysis and D-dimer in predicting PE in cancer patients. METHODS: Electronic medical records were reviewed between December 2005 and November 2010. A total of 177 computed tomography pulmonary angiograms (CTPAs) were performed...

Malignant tumors are often complicated with venous thrombosis and pulmonary embolism (PE), particularly in lung cancer. However, owing to the limited data regarding the clinical course about PE in lung cancer patients, the aim of this study is to analyze the risk factors and prognosis of patients with PE and lung cancer. We performed a retrospective case-control study, the clinical data of 90 patients in the First Affiliated Hospital of People's Liberation Army General Hospital between Jan 2010 and Jan 2015 were analyzed, including 30 lung cancer patients with PE (PE group), 60 lung cancer patients without PE (non-PE group), treated during the same period...

BACKGROUND: D-dimer has been used to rule out pulmonary embolism (PE). Based on previous reports of decreased concentrations of coagulation factor XIII (FXIII) in venous thromboembolism, and no change in FXIII concentration in patients with acute cardiovascular disease, we evaluated the benefit of simultaneously measuring D-dimer and FXIII concentrations for diagnosing PE. METHODS: In this prospective single-center study, we enrolled 209 patients initially suspected of having PE, and measured their D-dimer and FXIII concentrations...

OBJECTIVE: The objective was to estimate D-dimer interval likelihood ratios (iLRs) for diagnosing pulmonary embolism (PE). METHODS: The authors used pooled patient-level data from five PE diagnostic management studies to estimate iLRs for the eight D-dimer intervals with boundaries 250, 500, 750, 1,000, 1,500, 2,500, and 5,000 ng/mL. Logistic regression was used to fit the data so that an interval increase corresponds to increasing the likelihood ratio by a constant factor...

We present an autopsy case of repetitive stroke due to tumor emboli, indistinguishable from thromboembolism with a hypercoagulable state in its clinical course. A 72-year-old man diagnosed with stage IVA oropharyngeal squamous cell carcinoma received chemoradiotherapy. Follow-up imaging revealed mediastinal lymph nodes and pulmonary metastasis. One year later, the patient experienced right arm weakness, and brain magnetic resonance imaging showed acute ischemic lesions in multiple vascular territories. He was diagnosed with paradoxical cerebral embolism due to cancer-associated venous thrombosis and treated with rivaroxaban...

BACKGROUND Deep vein thrombosis (DVT) is a type of venous thromboembolism with diverse clinical and environmental risk factors. Very few cases of DVT with multiple high risk factors have been reported. Here, we report an uncommon DVT case with multiple etiological causes, including appendicitis/appendectomy, morbid obesity, immobilization, positive phosphatidylserine IgG, and heterozygous factor V Leiden mutation. CASE REPORT A 43-year-old female was brought to the emergency room because of 2-week history of pain and swelling and ultrasound revealing evidence of DVT in the right leg...
