Comparison of septic and nonseptic pulmonary embolism in children.
2021
BACKGROUND Septic pulmonary embolism (SPE) in children is a rare disease. Data are scarce regarding the clinical and laboratory manifestation of SPE compared with nonseptic pulmonary embolism (ns-PE). Furthermore, specific guidelines for the management of SPE in children are lacking. AIM We compared the clinical course and outcome of children with SPE and ns-PE. METHODS A retrospective, cohort study of hospitalized children, 2005-2020, with documented pulmonary embolism imaging. RESULTS Sixteen children (eight SPE, eight ns-PE) were identified. Episodes of SPE occurred secondary to endocarditis, musculoskeletal and soft tissue infections, with Staphylococcus aureus (n = 4) and streptococcus spp. (n = 2) as the most common pathogens. Radiographically, SPE presented as a microvascular disease with parenchymatic nodules/cavitations, whereas ns-PE presented as larger vessel disease with filling defects. Risk factors (including thrombophilia) were noted in 0% and 87.5% of SPE and ns-PE patients, respectively (p 4 months was administrated to 14.3% and 87.5% of SPE and ns-PE patients, respectively (p < .01). One ns-PE patient had a second thromboembolic event compared to none in the SPE group. CONCLUSIONS SPE in children is a unique subgroup of PE with different clinical and laboratory findings that requires a different diagnostic approach and probably shorter duration of antithrombotic treatment.
