COVID-19 associated with superior mesenteric artery thrombosis and acute intestinal ischemia

The thrombotic nature of extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been established because the starting of the worldwide coronavirus 2019 (COVID-19) pandemic. Mesenteric artery thrombosis and acute mesenteric ischemia, by themselves, are uncommon and sometimes current with deadly gastrointestinal (GI) ailments that require immediate identification and doctor intervention to enhance scientific outcomes. SARS-CoV-2 an infection can current with acute gastrointestinal illness and requires additional investigation relating to anticoagulant remedy in sufferers contaminated with COVID-19. We report a 64-year-old girl with SARS-CoV-2 who suffered from superior mesenteric artery thrombosis and acute intestinal ischemia.

an introduction

An infection with the coronavirus illness 2019 (SARS-CoV-2) coronavirus 2 (SARS-CoV-2) has been more and more related to coagulopathy and thrombotic problems. Though pulmonary displays of the illness predominated, extrapulmonary problems have additionally been reported in people with confirmed COVID-19. [1,2]. Acute mesenteric ischemia (AMI) is a much less widespread thrombotic complication, and is described in just a few case experiences. [3]however with excessive charges of morbidity and mortality [1,2,4]. This report describes a affected person with COVID-19 presenting with superior mesenteric artery thrombosis (SMA) and acute intestinal ischemia.

View standing

A 64-year-old girl with a earlier medical historical past of hypertension and diabetes offered to the emergency division after experiencing two days of constipation, stomach ache and distention. Whereas ready at triage, the affected person collapsed and have become unresponsive. He was discovered to have hypotension with a Glasgow Coma Scale (GCS) of 5, and she or he was rapidly taken to a shock bay, intubated, and started to compress the vessels. Laboratory work was important for lactic acid at 9.6 mmol/L, a predominantly neutrophilic leukocytosis of 19.37 × 10^3 cells/L, elevated D-dimer >20 μg/ml, and SARS-CoV-2 detected On the BioFire® Respiratory Panel (BioFire Diagnostics, Salt Lake Metropolis, Utah, USA). The electrocardiogram confirmed sinus tachycardia and there was a slight elevation of troponin, in line with kind II myocardial infarction (MI). Belly and pelvic computed tomography with distinction was important for pneumonia disseminated into loops of the small gut within the left decrease quadrant and pelvis (Figs. 1And the 2) in addition to decreased caliber of the diffuse ventral axis and superior mesenteric artery with the presence of air pockets within the mesenteric vessels within the left decrease quadrant (Figs. 3And the 4).

These findings had been extremely suggestive of non-obstructive intestinal ischemia and the affected person was taken for an pressing exploratory laparotomy. At the moment, the affected person was found to have ischemia within the SMA distribution space, which was eliminated, together with ischemia of the massive gut ensuing within the resection of the complete colon; The affected person was left with an estimated 150 cm of viable small gut upon closure. The ABTHERA™ vacuum-assisted wound closure machine (Acelity LP Inc., San Antonio, TX, US) was positioned and the affected person was returned to the Intensive Care Unit for follow-up follow-up and care. Through the subsequent two postoperative days, the affected person continued to deteriorate with progressive failure of a number of organs. The affected person was taken for an pressing second exploratory laparotomy, which was important for a 1 cm space of ​​necrosis on the anterior facet of the rectal stump. Because of this, the rectal stump was excised, successfully eradicating the ischemic space. Nonetheless, the affected person continued to deteriorate clinically. 9 days after his admission to the hospital, the affected person’s household decides to take solely snug care measures, after which the affected person rapidly expires.

Focus on

It has been recommended that SARS-CoV-2-induced thrombosis is because of microcirculatory adjustments. One speculation means that viral replication causes inflammatory cells to infiltrate the endothelium resulting in endothelial apoptosis and subsequent microvascular thrombosis occasions. [5]. As well as, SARS-CoV-2 has been proven to behave on the ACE-2 receptors within the lungs, that are additionally discovered within the vascular endothelium and in enterocytes of the small gut, supporting the microvascular coagulation results of SARS-CoV-2 on small vessels. . Gut [6]. Presentation of pulmonary embolism accounts for almost all of coagulopathy related to COVID-19; Nonetheless, there have been reported instances together with venous thromboembolism, arterial thrombosis, myocardial infarction, stroke, and microvascular thrombosis. [5].

An infection with SARS-CoV-2 is attributable to inhalation of aerosol droplets and is primarily characterised by respiratory signs. Gastrointestinal manifestations of COVID-19 corresponding to nausea, vomiting, diarrhea, and stomach ache have been documented; Nonetheless, the true prevalence of gastrointestinal signs amongst sufferers contaminated with the COVID-19 virus is unknown, starting from lower than 10% to 70% in varied experiences. [3,7]. Whereas AMI is uncommon with an total incidence of lower than 1%, AMI within the case of COVID-19 warrants a excessive diploma of suspicion to keep away from dangerous, probably deadly problems. [8]. Sufferers not too long ago medically handled in hospital for COVID-19 prophylactic extended-release with randomized and managed rivaroxaban (MICHELLE) remedy point out improved scientific outcomes with extended use of rivaroxaban anticoagulant in high-risk sufferers after hospital discharge, supporting prevention Anticoagulant for sufferers at elevated danger of thromboembolism [9].


As SARS-CoV-2 continues to create a big burden on healthcare, many sudden illness manifestations proceed to be described. Thromboembolic displays of the virus, corresponding to AMI, current important scientific challenges to clinicians as a consequence of their catastrophic and unpredictable nature. Early recognition of AMI and identification of these most in danger is vital for immediate scientific prognosis and remedy, which can result in higher scientific outcomes. Future investigation relating to anticoagulation prophylaxis in sufferers contaminated with COVID-19 is warranted contemplating the person affected person dangers and elevated morbidity and mortality related to AMI.
