Intestinal ischemia in the COVID-19 era: case series from peripheral healthcare centre

Coronavirus disease-2019 (COVID-19) caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) has caused global health crisis. Initially considered a respiratory tract pathogen, it can cause multiple organ dysfunction. It has also been described to predispose to venous and arterial thromboembolism; however, limited published data is available regarding mesenteric thrombosis COVID-19. We report 6 cases of COVID-19 positive patients with mesenteric/intestinal ischemia. These patients were examined with variables including demographics, laboratory blood tests including coagulation panels, medical and surgical history, comorbidities, and postoperative follow-up period.

Difficulties in the Radiation Diagnosis of Acute Mesenteric Thrombosis in Patients with Chronic Critical Illness

Acute mesenteric ischemia is an acute disruption of blood supply to part of the intestine, which, if untreated, leads to bowel wall necrosis and a patient’s death. Computed tomography (CT) plays a leading role in detecting mesenteric ischemia and in making the initial diagnosis, especially in patients with chronic critical illness, when productive contact is impossible. The final diagnosis is established during surgery or postmortem examination. Timely diagnosis and surgical treatment are a basic tool to reduce high mortality rates from this disease. The article presents the possibilities of CT in imaging and making the primary diagnosis of mesenteric ischemia and mesenteric thrombosis.

782 A Rare Complication in A Post-Operative Bariatric Patient: COVID-19 Induced Mesenteric Venous Thrombosis

Introduction The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has provided enormous challenges in the delivery of surgical care. In addition to respiratory tract infections, coronavirus disease 2019 (COVID-19) is associated with both arterial and venous thrombotic complications. Case Details: We present a case of acute superior mesenteric venous (SMV) thrombosis in a 36-year-old female patient who underwent Roux-en-Y gastric bypass three years previously. Her presentation with acute abdominal pain occurred 6 days after a positive nasopharyngeal swab. An admission CT scan demonstrated an abrupt cut off in the proximal SMV with resultant small bowel oedema. Subsequent thrombophilia screening and mutation testing for myeloproliferative neoplasms were all negative. She had also previously carried three pregnancies to term without any thrombotic complications. Hence, the high suspicion of acute COVID-19 induced mesenteric thrombosis. Conclusions In patients who have previously undergone Rouy-en-Y gastric bypass and lost significant weight, acute abdominal pain normally raises a high suspicion of internal hernia. However, as the pandemic progresses surgeons need to be mindful of COVID-19 induced mesenteric thrombosis as a differential diagnosis during the workup of acute abdominal pain. This was well demonstrated on a CT scan with intravenous contrast.
