Pulmonary Vascular Manifestations of COVID-19 Pneumonia |pdf=|usr=}}{{34036264}} gab.com Text Pulmonary Vascular Manifestations of COVID-19 Pneumonia JO: Radiol Cardiothorac Imaging http://www.kidney.de/pget.php?&tw=1&pmid=34036264 #FOAvip Purpose: To investigate pulmonary vascular abnormalities at CT pulmonary angiography (CT-PE) in patients with coronavirus disease 2019 (COVID-19) pneumonia. Materials and Methods: In this retrospective study, 48 patients with reverse-transcription polymerase chain reaction?confirmed COVID-19 infection who had undergone CT-PE between March 23 and April 6, 2020, in a large urban health care system were included. Patient demographics and clinical data were collected through the electronic medical record system. Twenty-five patients underwent dual-energy CT (DECT) as part of the standard CT-PE protocol at a subset of the hospitals. Two thoracic radiologists independently assessed all studies. Disagreement in assessment was resolved by consensus discussion with a third thoracic radiologist. Results: Of the 48 patients, 45 patients required admission, with 18 admitted to the intensive care unit, and 13 requiring intubation. Seven patients (15%) were found to have pulmonary emboli. Dilated vessels were seen in 41 cases (85%), with 38 (78%) and 27 (55%) cases demonstrating vessel enlargement within and outside of lung opacities, respectively. Dilated distal vessels extending to the pleura and fissures were seen in 40 cases (82%) and 30 cases (61%), respectively. At DECT, mosaic perfusion pattern was observed in 24 cases (96%), regional hyperemia overlapping with areas of pulmonary opacities or immediately surrounding the opacities were seen in 13 cases (52%), opacities associated with corresponding oligemia were seen in 24 cases (96%), and hyperemic halo was seen in 9 cases (36%). Conclusion: Pulmonary vascular abnormalities such as vessel enlargement and regional mosaic perfusion patterns are common in COVID-19 pneumonia. Perfusion abnormalities are also frequently observed at DECT in COVID-19 pneumonia and may suggest an underlying vascular process.Supplemental material is available for this article.© RSNA, 2020 Twit Text FOAVip Pulmonary Vascular Manifestations of COVID-19 Pneumonia ????Radiol Cardiothorac Imaging http://www.kidney.de/pget.php?&tw=1&pmid=34036264 #FOAvip Twit Text # Free Paper on # # # # # LINK http://www.kidney.de/pget.php?&tw=1&pmid=34036264 #FOAvip English Wikipedia <ref>{{Cite pmid|34036264}}</ref> Pulmonary Vascular Manifestations of COVID-19 Pneumonia #MMPMID34036264 Lang M; Som A; Carey D; Reid N; Mendoza DP; Flores EJ; Li MD; Shepard JAO; Little BP Radiol Cardiothorac Imaging 2020[Jun]; 2 (3): ä PMID34036264show ga Purpose: To investigate pulmonary vascular abnormalities at CT pulmonary angiography (CT-PE) in patients with coronavirus disease 2019 (COVID-19) pneumonia.
