Acute mesenteric thrombosis in two patients with COVID-19. Two cases report and literature review

INTRODUCTION: The coronavirus disease 2019 (COVID-19) affects mainly the respiratory system, other organs may be involved, usually due to coagulation disturbances that lead to a high rate of thrombotic complications. CASE PRESENTATION: The first patient is 45 years-old who has been exposed to SARS CoV-2. Upon admission due to acute abdomen evidence surgery is performed in which an intestinal resection with an adequate post-surgical evolution takes place so the patient is discharged after 4 days with a prescription for oral anticoagulants. The second one is 42 years-old and has comorbidities. The patient is admitted upon evidence of COVID-19, after showing signs of vein mesenteric ischemia in a CT scan surgery is performed, however the patient dies 24 h after the intervention. DISCUSSION: Within severe cases of patients with COVID-19 the incidence of a symptomatology or gastrointestinal complications is high (39–73.8%). Thromboprophylaxis is recommended to all patients admitted for COVID-19, starting with heparin of low molecular weight as prophylaxis, as well as continuing with oral anticoagulants after being discharged. CONCLUSION: Despite the fact that knowledge of the disease is rapidly advancing, all available treatments are still nonspecific to SARS-CoV-2 and the optimal management of COVID-19 remains unclear. An unexplained clinical picture should raise the suspicion for rare conditions such as mesenteric thrombosis. Adequate prophylactic measures should be implemented both during hospitalization and after discharge.
