Non-target lung embolization during portal vein embolization due to an unrecognized portosystemic venous fistula: A case report.

Background: Portal vein embolization (PVE) is an effective and relatively safe procedure performed prior to major hepatic resection to enhance future liver remnant. Non-target embolization during PVE is rare, and if it occurs, it usually affects the future liver remnant. Intrahepatic portosystemic venous fistulas are extremely rare in non-cirrhotic livers.

Pulmonary Embolism in COVID-19 Patients: A Retrospective Case-Control Study.

Background: Coagulopathy is a well-recognized complication in patients with coronavirus disease 2019 (COVID-19). Pulmonary embolism (PE) has substantial morbidity and mortality if the diagnosis is missed or the management is delayed. Computed tomography pulmonary angiography (CT-PA) is the imaging modality of choice for PE.
