OBJECTIVE: Thrombosis represents one of the most feared complications of the COronaVIrus Disease-2019 (COVID-19). Although pulmonary embolism and deep venous thrombosis are the most described complications, some investigations reported thrombotic localization also in the splanchnic venous district. METHODS: We describe the case of a patient with SARS-CoV-2 infection presenting with abdominal pain and diagnosed with portal vein thrombosis. In addition, we shortly review available literature supporting the possible role of COVID-19 as leading cause of splanchnic venous thrombosis. RESULTS: After in-depth diagnostic workup, we excluded the commonest causes of portal thrombosis and concluded that SARS-CoV-2 infection represented the main explanation of this finding. CONCLUSIONS: Our study warns the clinicians to maintain a high index of suspicion for thrombosis in patients diagnosed with SARS-CoV-2 infection manifesting gastrointestinal symptoms. An appropriate diagnostic work-up could allow to obtain an early diagnosis and consequently improve the clinical outcome of patients.

ObjectivesTo investigate how many general practitioner (GP)-referred venous thromboembolic events (VTEs) are diagnosed during 1 year in one geographical region and to investigate the (urgent) referral pathway of VTE diagnoses, including the role of laboratory D-dimer testing.DesignHistorical cohort study.SettingGP patients of 47 general practices in a demarcated geographical region of 161 503 inhabitants in the Netherlands.ParticipantsWe analysed all 895 primary care patients in whom either the GP determined a D-dimer value or who had a diagnostic work-up for suspected VTE in a non-academic hospital during 2015.Primary and secondary outcome measuresThe primary outcomes of this study were the total number of VTEs per year and the diagnostic pathways—including the role of GP determined D-dimer testing—of patients urgently referred to secondary care for suspected VTE. Additionally, we explored the use of an age-adjusted D-dimer cut-off.ResultsThe annual VTE incidence was 0.9 per 1000 inhabitants. GPs annually ordered 5.1 D-dimer tests per 1000 inhabitants. Of 470 urgently GP-referred patients, 31.3% had a VTE. Of those urgently referred based on clinical assessment only (without D-dimer testing), 73.8% (96/130) had a VTE; based on clinical assessment and laboratory D-dimer testing yielded 15.0% (51/340) VTE. Applying age-adjusted D-dimer cut-offs to all patients aged 50 years or older resulted in a reduction of positive D-dimer results from 97.9% to 79.4%, without missing any VTE.ConclusionsAlthough D-dimer testing contributes to the diagnostic work-up of VTE, GPs have a high detection rate for VTE in patients who they urgently refer to secondary care based on clinical assessment only.

The work-up and management of patients with acute liver failure in paediatric critical care are often challenging. This chapter takes the readers through definitions, grading of severity, and diagnostic work-up of acute liver failure in children. General principles underlying the management of acute liver failure, including immediate resuscitation and retrieval; organ support, including renal replacement therapy; and the management of complications, including bleeding, are discussed. In particular, this chapter focuses on neuromonitoring and neuroprotection strategies in children with hepatic encephalopathy as a complication. The role of liver transplantation in fulminant liver failure and a brief overview of complications are also discussed.

Test Probability

The diagnostic work-up of upper and of lower extremity deep vein thrombosis starts with the assessment of the pre-test probability by using a validated clinical decision rule, followed by imaging if deep vein thrombosis cannot reliably be rule out. For splanchnic vein thrombosis and cerebral vein thrombosis, the diagnostic assessment starts with imaging. Currently, the imaging techniques most widely used in clinical practice are compression ultrasonography, computed tomography, and magnetic resonance imaging, with a diagnostic standard dependent on the specific site of the venous thrombosis. This chapter provides an overview of the diagnostic accuracy and potential pitfalls of imaging techniques for the different sites of venous thrombosis.

SummaryIt is uncertain whether gender influences the clinical presentation of deep-vein thrombosis (DVT) and the discriminative value of the Wells diagnostic pretest probability score. The aim of the study was to determine whether gender impacts the clinical presentation and diagnosis of DVT. The study analysed a cohort of 4,976 outpatients with clinically suspected DVT of the leg prospectively recruited by 326 vascular medicine physicians in the German ambulatory care sector between October and December 2005. The diagnosis of DVT was based on compression ultrasonography in 96% of patients. Among 4,777 patients who had a diagnostic work-up for DVT there were more women (n=2,998) than men (n=1,779). However, the prevalence of confirmed DVT was 37.0% (658/1779) in men vs. 24.3% (730/2,998) in women (p<0.001). Among patients with confirmed DVT, proximal DVT was more common in men (59.6% vs. 44.5% in women, p<0.001). Swelling of the leg, pitting oedema and dilated superficial veins were more frequently reported by men (p<0.001). The percentage of patients with a high probability Wells clinical pretest score was higher in men than in women (67.0% vs. 57.0%, p<0.001). However, overall, the score equally discriminated risk groups for DVT in both sexes. In conclusion, women were more frequently referred for a diagnostic work-up for DVT than men, but the prevalence of DVT was higher in men and their thrombotic events were more severe. Nevertheless, the Wells clinical pretest probability score correctly identified low- and high-risk groups in both genders.
