Abstract
Coronavirus disease-19 (COVID-19) has triggered the worst public health crisis of modern times. The prothrombotic state induced by the infection is considered directly and substantially related to acute lung damage and other medical complications, including death. This scoping review summarises and critically assesses the existing evidence on the association between thrombosis and COVID-19, and is based on a systematic literature search of all articles published up to May 5(th), 2020, included in the following databases: PubMed, Scopus, Cochrane, and Clinicaltrials.gov. A total of 26 articles were included, and their quality evaluated using STROBE guidelines. The main symptoms presented by patients that had been diagnosed with COVID-19 are dyspnoea, fever, cough, diarrhoea, and vomiting. In the laboratory findings, it is characteristic to observe an increase in D-dimer, fibrinogen, prothrombin time, and lymphopenia. Ultrasound and computed axial tomography were the radiological techniques most used for diagnosing pulmonary thromboembolism, deep vein thrombosis, and other thrombotic phenomena. In conclusion, there is still limited scientific evidence on COVID-19 and its thrombotic complications. This review summarises the body of evidence, assesses its quality, and offers conclusions that should help in the next steps in this highly relevant and expanding research area.
