Splanchnic vein thrombosis associated with SARS-CoV-2 infection: a VALDIG case-control study

BackgroundWhether SARS-CoV-2 infection is a risk factor for splanchnic vein thrombosis (SVT) unknown.AimTo assess the impact of on presentation and prognosis recent SVT to identify specific characteristics SARS-CoV-2-associated SVT. Methods: Retrospective study collecting health-related data 27 patients presenting with in context 12 VALDIG centers comparison 494 before pandemic.ResultsTwenty-one had portal or without another vein, two superior mesenteric thrombosis, one splenic three hepatic thrombosis. Diagnosis was made 10 days (95%CI: 0-24) after diagnosis infection. Fever (52% vs. 15%, p<0.001) respiratory symptoms (44% 0%, were more frequent, median lymphocyte count lower (1.1 103/mm3 1.6 103/mm3, p=0.043) compared those A prothrombotic condition identified 44% 52% infection, respectively (p=0.5). All received anticoagulation therapy. During follow-up 250 days, SARS-CoV-2-infected (11%) required intestinal resection infarction 1 3 months 13 (2.6%) controls (p=0.044). Partial complete recanalization thrombosed performed 33% patients.ConclusionsSARS-CoV-2 can be associated Intestinal leading might frequent patients.
