    Abstract Introduction: Severe SARS-CoV-2 infection MESHD, responsible for COVID-19, is accompanied by venous thromboembolic MESHD events particularly in intensive care unit. In non-severe COVID-19 patients affected by neurovascular diseases MESHD, the prevalence SERO of deep venous thrombosis HP deep venous thrombosis MESHD ( DVT MESHD) is unknown. The aim of or study was to report data obtained after systematic Doppler ultrasound scanning ( DUS MESHD) of lower limbs in such patients. Methods: Between March 20 and May 2, 2020, consecutive patients with neurovascular diseases MESHD with non-severe COVID-19 were investigated with a systematic bedside DUS. Results Thirteen patients were enrolled including 10 acute ischemic strokes MESHD ischemic strokes HP, one transient ischemic attack HP ischemic MESHD attack, one cerebral venous thrombosis HP cerebral venous thrombosis MESHD and one haemorrhagic stroke MESHD stroke HP. At admission, the median National Institute of Health Stroke HP Stroke MESHD Scale (NIHSS) was of 6 (IQR, 0-20). We found a prevalence SERO of 38.5% of asymptomatic TRANS calves DVT MESHD (n=5) during the first week after admission despite thromboprophylaxis. Among them, one patient had a symptomatic pulmonary embolism HP pulmonary embolism MESHD. Two patients died during hospitalization but the outcome was favourable in the others with a discharge median NIHSS of 1 (IQR, 0-11). Discussion/Conclusion: Despite thromboprophylaxis, systematic bedside DUS showed a high prevalence SERO of 38.5% of DVT MESHD in non-severe COVID-19 patients with neurovascular diseases MESHD. Therefore, we suggest that this non-invasive investigation should be performed in all patients of this category.

    Background: Recent studies revealed a high prevalence SERO of venous thromboembolism HP (VTE) events in coronavirus disease 2019 (COVID-19) patients, especially in those who are critically ill. Available studies report varying prevalence SERO rates. Hence, the exact prevalence SERO remains uncertain. Moreover, there is an ongoing debate regarding the appropriate dosage of thromboprophylaxis. Methods: We performed a systematic review and proportion meta-analysis following PRISMA guidelines. We searched PubMed and EMBASE for studies exploring the prevalence SERO of VTE in critically ill COVID-19 patients till 22/07/2020. We pooled the proportion of VTE. Additionally, in a subgroup analysis, we pooled VTE events detected by systematic screening. Finally, we compared the odds of VTE in patients on prophylactic compared to therapeutic anticoagulation. Results: The review comprised of 24 studies and over 2500 patients. The pooled proportion of VTE prevalence SERO was 0.31 (95% CI 0.24, 0.39 I2 94%), of VTE utilizing systematic screening was 0.48 (95% CI 0.33, 0.63 I2 91%), of deep-venous-thrombosis HP was 0.23 (95% CI 0.14, 0.32 I2 96%), of pulmonary embolism HP was 0.14 (95% CI 0.09, 0.20 I2 90%). In a subgroup of studies, utilizing systematic screening, VTE risk increased significantly with prophylactic, compared to therapeutic anticoagulation (OR 5.45; 95% CI 1.90, 15.57 I2 0%). Discussion: Our review revealed a high prevalence SERO of VTE in critically ill COVID-19 patients. Almost 50% of patients had VTE detected by systematic screening. Higher thromboprophylaxis dosages seem to reduce VTE burden in this patient's cohort compared to standard prophylactic anticoagulation; ongoing randomized controlled trials will further confirm this.

    BackgroundDeep venous thrombosis HP venous thrombosis MESHD (DVT) is a severe complication of the coronavirus disease MESHD 2019 (COVID-19). It may interfere with COVID-19 treatment and delay the recovery, but there is less data about the anticoagulant therapy and sex difference of VTE MESHD in patients with COVID-19. The purpose of this study is to study the prevalence SERO, risk factors, anticoagulant therapy and sex difference of deep venous thrombosis HP deep venous thrombosis MESHD ( DVT MESHD) in patients with COVID-19.MethodsThe enrolled 121 patients were confirmed positive for COVID-19. All suspected patients with a high Caprini index (≥4) or PADUA index (≥4) received color Doppler Ultrasound (US) to screen DVT MESHD in both lower extremities. Clinical characteristics of DVT MESHD-COVID-19 patients were analyzed. Multivariate logistic regression was performed to identify risk factors related to DVT MESHD in COVID-19 patients. The distribution of DVT MESHD locations, anticoagulation therapy with sex difference, and the outcomes were also analyzed.ResultsDVT was found in 48% asymptomatic TRANS COVID-19 patients with increased PAUDA index or Caprini index by US scanning. Multivariate logistic regression determined that age TRANS, CRP and baseline D-dimer were risk factors among COVDI-19 patients. Although the most common DVT MESHD location was infrapopliteal (Class I and Class II), higher mortality in DVT MESHD-COVID-19 patients was confirmed. DVT MESHD-COVID-19 patients presented significant increases in the CRP, neutrophil count and D-dimer throughout the whole inpatient period compared to non- DVT MESHD-COVID-19 patients. Although anticoagulation therapy accelerated the recovery of lymphocytopenia condition MESHD in DVT MESHD patients, men DVT MESHD-COVID-19 patients showed higher CRP and neutrophil count vs. lymphocyte count (N/L) ratio but lower lymphocyte count compared to women DVT MESHD-COVID-19 patients. ConclusionsDVT is common in COVID-19 patients with high risk factors, especially for older age TRANS, higher CRP and baseline D-dimer populations. It is important to consider sex differences in the anticoagulant therapy among DVT MESHD-COVID-19 patients.
