Abstract

Abstract: Background: The venous thromboembolism (VTE) is a frequent condition, which may worsen the prognosis of hospitalized COVID-19 patients. Nevertheless, the incidence of this complication is unknown in patients with mild COVID-19 symptoms. Case summary: A 26-year-old female nurse, who had been taking oral contraceptive pills (OCPs) treatment for the last 2 years, developed mild COVID-19 symptoms (rhinitis and anosmia). She underwent isolation at home and was subsequently followed up with telehealth visits. Fifteen days after her initial presentation, she developed acute onset sudden dyspnoea. On physical examination, she was found to be tachycardic with normal pulse oximetry. The initial risk score for VTE was moderate and laboratory results showed increased D-dimer level without other relevant findings. Computed tomography pulmonary angiography was performed, which confirmed low-risk subsegmental pulmonary embolism. Discussion: Venous thromboembolism in patients who present with severe COVID-19 symptoms has already been described in the literature; its incidence is greater in patients hospitalized in intensive care units. Efforts to prevent VTE based on risk scores are widely recognized. However, the relationship in patients who present with mild COVID-19 symptoms and VTE is still unknown. Recently, experts on this field have introduced thromboprophylaxis guidelines including ambulatory patients based on the severity of COVID-19 symptoms and pro-thrombotic risk. Our patient showed no major risk for developing VTE; therefore, the VTE could be associated with SARS-CoV-2 infection or the eventual pro-thrombotic association with the concomitant use of OCPs.
