Introduction: More than 532 million cases of COVID-19 infection have been documented, and hundreds of thousands are being added every day. COVID-19 is linked to a number of co-morbidities, one of which, hypercoagulability, has piqued the interest of many researchers. Here, we present a case of a portal vein and superior mesenteric vein thrombosis in a patient with subclinical COVID-19 infection.
Case Description/Methods: A healthy 30-year-old male presented 3 weeks after having mild, asymptomatic COVID with epigastric abdominal pain, nausea, and vomiting. His only complaints when he had COVID was a decreased appetite, but no other gastrointestinal (GI) or respiratory symptoms. Upon admission, initial CT with contrast showed thrombophlebitis of superior mesenteric vein (SMV) and portal vein (PV), decreased contrast within the intrahepatic PVs; follow up MR Angiography revealed PV intraluminal filling defect beginning just distal to the superior mesenteric vein and splenic vein confluence and involving the intrahepatic PV with periportal edema. He denied any prior clots nor family history of clotting disorder. GI and hematology were consulted. He received catheter-directed tPA for 2 days due to abdominal pain and follow up CT angiogram with no evidence of occlusion in arteries. The cause for his extensive abdominal vasculature thrombosis is thought to be secondary to COVID hypercoagulability, and the location has not been well delineated. Abdominal pain improved, he continued anticoagulation (AC), did not require repeat sessions with plans for close follow up imaging.
Discussion: Klok et al. reported a crude cumulative thrombosis incidence in COVID19 ICU patients is of 57% (95% CI 47–67%). In terms of intestinal damage, prothrombotic effects of the virus rises the incidence of mesenteric ischemia from 0.09–0.2% in the normal population to 1.9–3.8% in COVID-19 patients. Thrombosis is a known outcome, but in our case, this location is atypical, and he required catheter directed tPA by IR due to abdominal pain, that is a large measure and not typically done for thrombosis so it is also an aggressive management for thrombosis (done due to unrelenting abdominal pain). Hereby, we conclude that any vascular complication without an underlying reason should raise suspicion of an underlying COVID-19 infection, and more research should be done to determine the risk of such complications.
