Background: Coronavirus 2019 (COVID-19) is a systemic disease associated with severe gastrointestinal complications including life-threatening mesenteric ischemia. We sought to review and summarize the currently available literature on the presentation, management, and outcomes of mesenteric ischemia in patients with COVID-19. Patients and Methods: The PubMed database was searched to identify studies published between January 2020 and January 2021 that reported one or more adult (≥18 years) patients with COVID-19 who developed mesenteric ischemia during hospitalization. The demographic characteristics, clinical and imaging findings, management, and outcomes of patients from each study were extracted and summarized. Results: A total of 35 articles reporting on 61 patients with COVID-19 with mesenteric ischemia met the eligibility and were included in our study. The mean age was 60 (±15.9) years, and 53% of patients were male. Imaging findings of these patients included mesenteric arterial or venous thromboembolism, followed by signs of mesenteric ischemia. Sixty-seven percent of patients were taken to the operating room for an exploratory laparotomy and bowel resection and 21% were managed conservatively. The terminal ileum was the most commonly involved area of necrosis (26%). The mortality rate of patients with COVID-19 with mesenteric ischemia was 33%, and the most common cause of death was multiorgan failure or refractory septic shock. Twenty-seven percent of patients managed operatively died during the post-operative period. Conclusions: Mesenteric ischemia in patients with COVID-19 is a devastating complication associated with a high rate of morbidity and mortality. Further efforts should focus on developing strategies for early recognition and management.
