Characteristics, management, and outcomes of segmental and subsegmental pulmonary embolism in ICU patients: A retrospective cohort study
Researchers reviewed 896 CT pulmonary angiograms from 804 ICU patients between January 2019 and June 2025. Pulmonary embolism was identified in 164 examinations, while 104 patients had segmental or subsegmental embolism without a more proximal clot. Anticoagulation was given to 96% of this group and 86% of treated patients received therapeutic dosing. At 90 days, bleeding occurred in 15%, major bleeding in 12%, recurrent venous thromboembolism in 7.8% and mortality in 24%.
