Background It remains unclear whether the distal location of deep vein thrombosis (DVT) is independently associated with a lower risk of recurrence in all patients, or represents a marker of the presence and severity of provoking factors for venous thromboembolism (VTE). Methods We investigated the impact of distal (vs. proximal) DVT location on the risk of developing symptomatic, objectively confirmed recurrent VTE in 831 patients with a first acute symptomatic DVT not associated with pulmonary embolism (PE), who were stratified by the presence of transient or persistent risk factors at baseline. The primary outcome was symptomatic, objectively diagnosed recurrent VTE, including proximal …

Frequency of thrombosis is higher in MPN patients who develop second cancer than in controls

2019

Introduction Malignancy can be heralded by unprovoked venous thromboembolism (VTE) but also by arterial thrombosis. To date it is unknown whether this association is present also in myeloproliferative neoplasms (MPN), in which arterial thrombosis is more frequent that venous thrombosis and solid tumors are reported with an increased frequency. The MPN-K nested case-control study addressed the impact of cytoreductive drugs on the risk of developing second cancer in MPN patients (Barbui T et al, Leukemia 2019); here we re-examined the study database to evaluate the frequency and type of vascular complications in MPN patients with second cancer excluding leukemia and to establish whether arter…

Objective Assessment of Pulmonary Embolism Can Be Deferred without Increased Risk

2005

Abstract Background. Management of patients with suspected Pulmonary Embolism (PE) is problematic if diagnostic imaging is not available. Pretest Clinical Probability (PCP) and D-dimer (D-d) assessment were shown to be useful to identify those high risk patients for whom empirical, protective anticoagulation is indicated (Siragusa S et al. Arch Intern Med2004;164:2477–82). Objective of the study. In consecutive patients with suspected PE, we evaluated whether PCP and D-d assessment, together with the use of low molecular weight heparins (LMWHs), allow objective appraisal of PE to be deferred for up to 72 hours. Methods. In case of deferment of diagnostic imaging for PE, patients identified …

P5017Factors associated with a negative D-dimer test in patients diagnosed with acute symptomatic pulmonary embolism

2019

Abstract Background The recommended diagnostic strategy for suspected acute pulmonary embolism (PE) combines the assessment of pre-test probability, D-dimer level, and -if indicated- computed tomography pulmonary angiography. Purpose To evaluate the frequency and potential explanations for negative D-dimer tests in patients diagnosed with acute PE. Methods The multicentre Follow-up of Acute Pulmonary Embolism (FOCUS) cohort study prospectively enrolled 1,100 consecutive patients diagnosed with acute symptomatic PE; two-year follow-up is ongoing. The items of the Simplified revised Geneva Score and the D-dimer levels at diagnosis have been prospectively collected, but they did not necessaril…

Artefaktreduzierung bei der Lungenemboliediagnostik mittels Spiral-CT unter Verwendung eines Kochsalzbolus

2001

nary Arteries Using a Saline Push. Purpose: To improve the diagnostic efficacy of bolus-enhanced spiral CT (SCT) in the detection of pulmonary embolism using a saline push immediately after bolus injection of the contrast medium. Patients and Methods: The study included 90 patients with suspected acute or chronic pulmonary embolism. The CT scan was performed in a caudocephaled direction. In Group I (n=60) we applied a bolus contrast injection (120 ml, 3 ml/s, 300 mg J/ml), after a median delay of 25 s. Group II (n = 30) had the same contrast injection which was immediately followed by an additional saline push (60 ml, 2 ml/s). Streak artifacts originating from high contrast concentrations i…

Endovascular thrombectomy with the AngioJet System for the treatment of intermediate-risk acute pulmonary embolism: a case report of two patients

2016

Acute pulmonary embolism (PE) is one of the leading causes of death and ranks third, after myocardial infarction and cerebral stroke, among fatal hospital-related cardiovascular events [1–3]. Mortality associated with PE can be lowered by early treatments aimed at restoring patency of occluded pulmonary arteries (PAs). Although systemic thrombolysis remains the recommended management of PE [4], recent advances in endovascular techniques, especially of rheolytic thrombectomy, suggest that the endovascular approach can represent an alternative therapeutic strategy [5–9]. Here we describe endovascular treatment of two patients with acute PE. We used the AngioJet (Boston Scientific, Natick, MA,…

Traumatic Venous Aneurysm of the Popliteal Vein with Outcome: A Case Report and Review of the Literature

2001

A case of sudden death due to recurrent pulmonary thromboembolism is described. The fatality took place three and a half weeks following blunt trauma to the left popliteal region. The patient died unexpectedly. Autopsy revealed the source of the emboli as a sacciform venous aneurysm of the popliteal vein, an entity seldom described, but important to consider in cases of soft tissue popliteal masses or unexplained pulmonary embolism, especially in otherwise healthy individuals.

Risk and Benefit of STA/MCA Anastomoses

1985

The advantage of EC/IC operation has not yet been proved unequivocally enough. We therefore attempted to analyze our cases in order to establish the possible benefit and risk of the operation. We compared the outcome of the operated and nonoperated patients with reference to the literature.
