Post-COVID-19 superior mesenteric artery and jejunal branches thromboembolism.

The World Health Organization has declared the novel coronavirus disease 2019 (COVID-19) a global public health emergency. Despite the predominating respiratory symptoms occurring in COVID-19, thrombosis can occur in some patients, with morbidity and mortality increase due to the respiratory worsening. This article reports the case of a 62-year-old man with a flu-like illness that was diagnosed as COVID-19 by RT-PCR of SARS-CoV-2. After three weeks, he subsequently developed abdominal pain in addition to bloating, nausea, and vomiting. He underwent exploratory laparotomy after imaging tests suggested mesenteric ischemia. Intestinal ischemia was evident, due to the absence of flow in the superior mesenteric artery and jejunal branches. Embolectomy and enterectomy were performed and they resulted in a favorable outcome, with clinical improvement. This case adds data to the limited literature on extrapulmonary complications of COVID-19, notably those related to thromboembolic events.

La Organización Mundial de la Salud ha declarado la enfermedad del nuevo coronavirus 2019 (COVID-19) una emergencia de salud pública mundial. A pesar de los síntomas respiratorios predominantes en COVID-19, la trombosis puede ocurrir en algunos pacientes, con un aumento de la morbimortalidad debido al empeoramiento respiratorio. Presentamos el caso de un hombre de 62 años con enfermedad similar a la gripe que fue diagnosticada como COVID-19 por RT-PCR de SARS-CoV-2. Después de tres semanas, desarrolló dolor abdominal además de hinchazón, náuseas y vómitos. Fue sometido a laparotomía exploradora luego de que las pruebas de imagen sugirieran isquemia mesentérica. Se evidenció isquemia intestinal por ausencia de flujo en la arteria mesentérica superior y ramas yeyunales. Se realizó embolectomía y enterectomía con evolución favorable, con mejoría clínica. Este caso añade datos a la limitada literatura sobre las complicaciones extrapulmonares del COVID-19, en particular las relacionadas con eventos tromboembólicos.

Superior Mesenteric Arterial and Venous Thrombosis in COVID-19.

BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) commonly present with fever, constitutional symptoms, and respiratory symptoms. However, atypical presentations are also well known. Though isolated mesenteric arterial occlusion associated with COVID-19 has been reported in literature, combined superior mesenteric arterial and venous thrombosis is rare. We report a case of combined superior mesenteric arterial and venous occlusion associated with COVID-19 infection. CASE REPORT: We report a case of a 45-year-old man who was a health care worker who presented to the emergency department with severe abdominal pain. The clinical examination was unremarkable, but imaging revealed acute mesenteric ischemia caused by superior mesenteric artery and superior mesenteric vein occlusion. Imaging of the chest was suggestive of COVID-19 infection, which was later confirmed with reverse transcription polymerase chain reaction of his nasopharyngeal swab. To date, only 1 case of combined superior mesenteric artery and superior mesenteric vein thrombosis caused by COVID-19 has been reported. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: During the COVID-19 pandemic it is important to keep mesenteric ischemia in the differential diagnosis of unexplained abdominal pain. Routinely adding high-resolution computed tomography of the chest to abdominal imaging should be considered in patients with acute abdomen because it can help to identify COVID-19 immediately. © 2020 Elsevier Inc.

Superior Mesenteric Artery Thrombosis and Acute Intestinal Ischemia as a Consequence of COVID-19 Infection.

BACKGROUND The novel COVID-19 disease caused by the SARS-CoV-2 virus is a highly infectious disease that originated in Wuhan, China, and has rapidly spread throughout the world. In addition to respiratory complications, the virus has also been implicated in damage to other organ systems as well as coagulopathy. The present report describes the first presumptive case of COVID-19-associated acute superior mesenteric artery thrombosis and acute intestinal ischemia. CASE REPORT A 55-year old man presented to the emergency department with nausea, generalized abdominal pain and diarrhea; he denied having a fever or any respiratory symptoms. Computed tomography (CT) of the abdomen and pelvis revealed bilateral pulmonary ground-glass opacities. He tested positive for SARS-CoV-2, and was treated with hydroxychloroquine, azithromycin and ceftriaxone, and was discharged home after five days of inpatient treatment. One week later, the patient returned with recurrent nausea, vomiting and worsening diffuse abdominal pain. A CT scan of the abdomen showed a 1.6-cm clot, causing high grade narrowing of the proximal superior mesenteric artery and bowel ischemia. The patient emergently underwent exploratory laparotomy, thromboembolectomy and resection of the ischemic small bowel. A post-operative complete hypercoagulable workup was unrevealing. CONCLUSIONS Despite the absence of respiratory symptoms, patients infected with SARS-CoV-2 may show atypical presentations, such as gastrointestinal symptoms. Clinicians managing patients with suspected or confirmed SARS-CoV-2 infection during the COVID-19 pandemic should monitor these patients for potential complications that may arise from this disease.
