Cerebral blood flow velocities after subarachnoid haemorrhage in relation to the amount of blood clots in the initial computed tomography.

1998

In 72 patients with acute subarachnoid haemorrhage (SAH) the relationship between the amount of subarachnoid blood clots detected by initial cranial computed tomography (CCT) up to 48 hours after bleeding and the later development of vasospasm, established by blood flow velocity measurement with transcranial Doppler ultrasound (TCD) was investigated. The serial Doppler examinations started within the first 72 hours after SAH and were carried out every second day up to three weeks. Each Doppler recording was accompanied by a neurological examination. Patients classified as Hunt and Hess grade V were excluded from the study. All patients with remarkable brain oedema in CCT or with intracrania…

Management of venous thromboembolism in patients with acute leukemia at high bleeding risk: a multi-center study

2016

In the last decades, evaluation of clinically relevant thrombotic complications in patients with acute leukemia (AL) has been poorly investigated. The authors performed a multi-center study to evaluate the management of symptomatic venous thromboembolism (VTE) in adult patients with AL. The intention was to find as clinically relevant the following: symptomatic Venous Thrombosis (VT) occurred in typical (lower limbs) and atypical (cerebral, upper limbs, abdominal, etc) sites with or without pulmonary embolism (PE). Over a population of 1461 patients with AL, 22 cases of symptomatic VTE were recorded in hospitalized patients with a mean age of 54.6 years. The absolute incidence of VTE was 1.…

Increased risk for venous thrombosis in carriers of the prothrombin G→A20210 gene variant

1998

A mutation in the prothrombin gene (G--A20210) has been associated with higher plasma prothrombin levels and an increased tendency for venous thrombosis.To determine whether the prothrombin A20210 allele is independently associated with the occurrence of venous thrombosis.Case-control study.Two thrombosis centers in southern Italy.281 consecutive patients with venous thrombosis confirmed by objective tests and 850 controls.Medical history was collected on standardized questionnaires. The presence of prothrombin G--A2020 and factor V Leiden mutations was determined by polymerase chain reaction. The presence of anticoagulant factors and prothrombin activity was determined by tests of function…

Trends in mortality related to pulmonary embolism in the European Region, 2000-15: analysis of vital registration data from the WHO Mortality Database

2020

Summary Background European estimates of the burden imposed by pulmonary embolism are not available to this date. We aimed to assess pulmonary embolism-related mortality and time trends in the WHO European Region. Methods We analysed vital registration data from the WHO Mortality Database (2000–15) covering subregions of the WHO European Region: Eastern Europe, Northern Europe, Southern Europe, Western Europe, and Central Asia. Deaths were considered pulmonary embolism-related if International Classification of Disease-10 code for acute pulmonary embolism (I26) or any code for deep or superficial vein thrombosis was listed as the primary cause of death. We used locally estimated scatterplot…

Incidence of venous thromboembolism in patients undergoing thoracotomy for lung cancer

2008

Limited information exists on the incidence of symptomatic venous thromboembolism (vTE) in patients undergoing chest surgery for lung cancer. Several factors increase the thromboembolic risk in patients undergoing surgery for lung cancer: the intrinsic procoagulant effect of cancer,extensive surgical intervention, dependent limb position in the operating room, and vessel injury consequent to the operation. Furthermore,these patients might be especially vulnerable to pulmonary embolism (PE) because of the loss of lung tissue and the presence of chronic obstructive pulmonary disease and cardiovascular diseases caused by smoking.t Older studies found a very high incidence of thromboembolic eve…

Outcome of patients with right heart thrombi: the Right Heart Thrombi European Registry

2015

Our aim was the assessment of the prognostic significance of right heart thrombi (RiHT) and their characteristics in pulmonary embolism in relation to established prognostic factors.138 patients (69 females) aged (mean±sd) 62±19 years with RiHT were included into a multicenter registry. A control group of 276 patients without RiHT was created by propensity scoring from a cohort of 963 contemporary patients. The primary end-point was 30-day pulmonary embolism-related mortality; the secondary end-point included 30-day all-cause mortality. In RiHT patients, pulmonary embolism mortality was higher in 31 patients with systolic blood pressure <90 mmHg than in 107 normotensives (42% versus 12%,…

Thromboembolic events in Fabry disease and the impact of factor V Leiden

2015

Although several reports suggest an increased thromboembolic event rate, especially regarding strokes and TIAs at early age in patients with Fabry disease (FD), the risk for patients with FD to experience these events, the clinical relevance of additional risk factors including the concurrence of factor V Leiden (FVL), and the benefit of enzyme replacement therapy (ERT) regarding these events remain unclear.Three hundred four consecutively recruited patients with FD were evaluated for their lifetime occurrence of thromboembolic events such as stroke, TIA, deep vein thrombosis, and pulmonary embolism. The thromboembolic risk was determined in patients with FD and concurrent FVL, and the impa…

Deferral of assessment of pulmonary embolism

2007

We evaluated a simplified algorithm for safely postponing diagnostic imaging for pulmonary embolism (PE). At the index visit, patients were identified as being at high or low risk of PE; the former received full dosage low molecular weight heparin while the latter were left untreated until performance of diagnostic imaging (max 72 hours). During this period, no thromboembolic events occurred in low-risk patients (0/211, 0.% [upper 95% CI 0.9%]); only one event occurred in those at high-risk (1/125, 0.8% [upper 95% CI, 1.2]). Our study demonstrates that diagnostic imaging for PE can be safely deferred for up to 3 days.

Sex-specific differences in the distal versus proximal presenting location of acute deep vein thrombosis

2018

Abstract Background and aims Women present with pulmonary embolism (PE) more often than men, while the opposite is true for proximal deep vein thrombosis (DVT). We investigated whether sex-specific differences exist in the presenting location of acute symptomatic DVT among patients without concomitant PE. Methods We tested our hypothesis in a meta-analysis of studies selected by systematically reviewing PubMed, Embase, and the grey literature. Thereafter, we analysed data of a single-center cohort including patients with first isolated acute DVT to assess the additional impact of age and provoking risk factors on the presenting location of DVT. Results We identified 7 studies for a total of…
