ABSTRACT
AJOL : Background: Haemorrhages in coronavirus disease 2019 (COVID-19) patients require proper knowledge and management.Objectives: To highlight the characteristics of haemorrhages in patients with COVID-19 infection.Method: A retrospective study examined CT scans performed over a 13-month period in patients hospitalised with COVID-19 infection to determine those who developed spontaneous bleeding. The authors also investigated correlations between the bleeding events and the patients' characteristics.Results: Haemorrhages occurred in 2.22% (31/1396) of patients hospitalised with COVID-19 infection (7.88%, 19/241 in the intensive care unit). Bleeding, major in most cases, occurred in anticoagulated patients, especially males with multiple comorbidities, aged between 60 and 79 years and mainly appeared in a single anatomical region (especially retroperitoneal), with the most voluminous in the chest wall. The complication was diagnosed on average 16.7 days after admission and occurred predominantly in critically ill patients undergoing invasive ventilation and pronation-supination cycles. In just under half of the cases, the haematomas were active, and in these cases, mainly with a single contrast blush and with earlier onset after the start of anticoagulation than in non-active bleeding. Major bleeding was also earlier in the presence of multiple morbidity. The vast majority of patients were treated conservatively and survived.Conclusion: At COVID-19 hospital centres, it is advisable that there is knowledge of such a complication for which CT imaging is essential for diagnosis and proper management. Although some authors have expressed doubts about anticoagulant treatment in patients with COVID-19, the bleeding complication in this study did not significantly affect the outcome.Contribution: Spontaneous haemorrhage did not significantly affect the outcome in this series
ABSTRACT
Background The primary aim of this study was to provide additional data of neuroimaging features of coronavirus disease 2019 (COVID-19) in a large-scale population admitted in several northern Italy institutions. The secondary aim was to analyze acute cerebrovascular disease (CVD) prevalence in COVID-19. Methods A database of confirmed COVID-19 hospitalized patients who developed acute neurological symptoms and underwent any neuroimaging was retrospectively gathered from twelve institutions based in Lombardy from February 21st to July 10th. To assess the prevalence of CVD we conducted a scoping review following the PRISMA extension guidelines for scoping reviews. We searched PubMed/Medline, SCOPUS and EMBASE databases for peer-reviewed in-press or published studies from December to January 2021 reporting CVD in COVID-19 patients. Results Out of 90 COVID-19 patients who were referred to neuroimaging, 78 (87%) showed CVD, in particular 65 had acute ischemic strokes (AIS), 8 had intracerebral hemorrhages, 2 subarachnoid hemorrhages (SAH) and 3 showed clinical and imaging findings in keeping with posterior reversible encephalopathy syndrome (PRES); 6 patients (7%) showed clinical and imaging findings highly suggestive of encephalitis; 3 patients (3%) showed demyelinating diseases: 1 case of MS progression, 1 case of newly diagnosed MS and 1 case of acute disseminated encephalomyelitis (ADEM); 2 cases (2%) acuity of chronic subdural hematoma (cSDH); 1 patient (1%) with Guillain Barré syndrome. In addiction two patients with CVD developed cauda polyradiculitis and tetraparesis. In our scoping review out of 3275 studies, 24 satisfied the inclusion criteria: in a pooled total population of 136198 patients, the pooled prevalence of CVD was 0.9%. In particular 0.8% of AIS and 0.1% of ICH and 0.003% of PRES. Conclusions Our study shows a high prevalence of CVD among patients who developed acute neurological symptoms, which is in line with papers reporting data comparable to ours. The heterogeneity of clinical reports, however, constitutes a limitation when comparing our findings with those of the clinical papers. Nonetheless, CVD could be a frightening association with COVID-19, particularly in critically ill patients. Healthcare policymakers and clinicians should be prepared to a likely increase in workload and to rearrange the strategy of healthcare delivery.
