Abstract:
Cases of coronary and pulmonary artery pseudoaneurysms secondary to COVID-19 have been reported in the literature and are supposed to be secondary to inflammatory and vasculitis processes linked to a viral multisystem inflammatory syndrome. Although the incidence of COVID-19-associated liver injury ranges from 14% to 53% in hospitalized patients, COVID-19-associated hepatic artery pseudoaneurysms have never been reported so far. We present the case of a patient whose follow-up CT after cryoablation of renal cell carcinoma revealed seven fusiform pseudoaneurysms of the two hepatic arteries secondary to COVID-19. Anticoagulant or anti-inflammatory treatments were not introduced. Vascular lesions were unchanged on the 3-month follow-up CT. At 6-month CT, the proximal pseudoaneurysm was replaced by a proximal occlusion of the accessory RHA.
