Abstract Number: PB1173
Meeting: ISTH 2021 Congress
Background: Subacute mesenteric venous thrombosis (SMVT) is a vascular complication commonly associated with hypercoagulability, resulting in abdominal pain and ischemia of the intestines.
Aims: This case exemplifies the heterogeneous presentation of late thrombotic complications in COVID-19 and the relevance of prophylactic measures against hypercoagulability.
Methods: We carried a full investigation of the patient to gather all the information needed to conclude the origin of his thrombotic episode.
We report a 44 y/o male without relevant history and COVID-19 disease who developed abdominal pain after the onset of respiratory symptoms. The initial differential diagnosis from surgical evaluation for the patient’s abdominal pain included mesenteric ischemia, bowel obstruction, and pancreatitis. Imaging studies by computed tomography (Fig.1) demonstrated defined hypodensities in the portal vein, venous filling defects, vein enlargement, and engorgement (yellow arrows). Doppler ultrasound (Fig.2) showed abnormal flow consistent with thrombosis of mesenteric veins. He was successfully treated with anticoagulation therapy.
Conclusions: Reports on coagulopathy are on the rise yet the question remains on how to predict these complications. It is relevant to consider prophylactic measures for avoiding hypercoagulability. Progressive diffuse abdominal pain with no significant alterations on coagulation profile or other risk factors should raise the awareness for mesenteric thrombosis. Actually, few cases of intestinal thrombosis exist in the literature considering our patient one of the first cases of subacute mesenteric venous thrombosis in a non-severe COVID-19 patient. More case reports and descriptive data are needed in the literature to increase the index of suspicion for these types of complications.
