AbstractRecent reports have suggested an increased risk of pulmonary embolism (PE) related to COVID-19. The aim of this cohort study is to compare the incidence of PE during a 3-year period and to assess the characteristics of PE in COVID-19. We studied consecutive patients presenting with PE (January 2017 –April 2020). Clinical presentation, computed tomography (CT) and biological markers were systematically assessed. We recorded the global number of hospitalizations during the COVID-19 pandemic and during the same period in 2018-2019. We included 347 patients: 326 without COVID-19 and 21 with COVI D-19. Patients wi...

CONCLUSIONS: Mechanically ventilated COVID-19 patients present with an imbalance between markedly increased factor V/VIII activity and overwhelmed protein C/S pathway. Plasma D-dimer may be a useful biomarker at the bedside for suspicion of VTE. PMID: 32965009 [PubMed - as supplied by publisher]

Conclusions: We report a 100% occurrence of venous thromboembolism in critically ill patients supported by venovenous extracorporeal membrane oxygenation for severe acute respiratory syndrome coronavirus 2-related acute respiratory distress syndrome using CT scan imaging despite a high target and close monitoring of anticoagulation.

COVID-19 patients have a strong propensity to develop thrombosis and their respiratory symptoms often prompt clinicians to assess for the presence of a pulmonary thromboembolism (PTE) [1,2]. Prior research estimates that approximately 20% to 30% of patients with COVID-19 have a PTE demonstrated by computed tomography pulmonary angiography (CTPA) [3,4]. Some clinical decision rules such as the Pulmonary Embolism Rule-Out Criteria (PERC) and Wells' Criteria are used to assess a patient's risk of PTE.

Contrast-enhanced chest computed tomography (CT) with dual-energy technique in a 69-year-old patient with coronavirus disease 2019 (COVID-19) pneumonia demonstrated ground-glass opacities, crazy paving, and patchy consolidation (Fig a). Furthermore, filling defects were seen in segmental arteries of both lower lobes in keeping with pulmonary embolism (Fig b, arrow). Bilateral deep vein thrombosis was present (Fig c, arrowheads). The iodine map illustrated multiple peripheral wedge-shaped perfusion defects not only in the lower but also in the upper lobes, suggesting more pronounced embolism than suspected from visible intr...

CONCLUSION: In addition to microvascular thrombosis, our results indicate a functional pulmonary vasodysregulation as part of the pathophysiology during the vascular phase of COVID-19. The clinical relevance of autopsies and the integration of radiological imaging findings into histopathological injury patterns must be emphasized for a better understanding of COVID-19.

Current guidelines recommend the use of unenhanced chest computed tomography (CT) as first-line imaging in patients suspected of having COVID-19 pneumonia, in order to assess the extent of lung damage [1,2]. Although most patients have a favorable disease course, some of them develop secondary disease worsening due to an excessive systemic inflammatory response, evidenced by high serum levels of biomarkers such as IL-6, which promotes an hypercoagulability state leading to thrombotic complications [3,4].

AbstractThe association between coronavirus disease 2019 (COVID-19) pneumonia and venous thrombotic disorders is still unclear. We assessed the association between COVID-19 infection-related pneumonia and proximal deep-vein thrombosis (DVT) in a cohort of patients admitted to our hospital during the European outbreak in the front line of Cremona, Lombardy. In a single-center cross-sectional study, all patients hospitalized for more than 5  days in Internal Medicine Department with confirmed COVID-19 pneumonia received 2-point compressive ultrasound assessment (CUS) of the leg vein system during a single day. Ninety-fo...

CONCLUSIONS: Physiologic, hematologic and imaging data show not only the presence of a hypercoagulable phenotype in severe Covid-19 pneumonia but also markedly impaired pulmonary perfusion likely caused by pulmonary angiopathy and thrombosis.

Authors: Jiang ZZ, He C, Wang DQ, Shen HL, Sun JL, Gan WN, Lu JY, Liu XT Abstract In December 2019, an outbreak of coronavirus infection emerged in Wuhan, Hubei Province of China, which is now named Coronavirus Disease 2019 (COVID-19). The outbreak spread rapidly within mainland China and globally. This paper reviews the different imaging modalities used in the diagnosis and treatment process of COVID-19, such as chest radiography, computerized tomography (CT) scan, ultrasound examination, and positron emission tomography (PET/CT) scan. A chest radiograph is not recommended as a first-line imaging modality for COVI...
