Neurological Injury and Cerebral Blood Flow in Single Ventricles Throughout Staged Surgical Reconstruction

CirculationPublished Prospective cohort study

Authors' conclusion

Significant brain abnormalities are commonly present in patients with a single ventricle, and detection of these lesions increases as children progress through staged surgical reconstruction, with multiple coexisting lesions more common earlier than later.

Study context

Population
Patients with a single ventricle undergoing staged surgical reconstructionscans in 168 subjects
Participants
235 patients
Exposure
Pre-BDG vs BDG vs post-Fontan stages
  • Pre-BDGn = 63reference
  • BDGn = 118
  • Fontann = 54
Outcome
Brain abnormalities on MRI by surgical stage
Methodological detailsserial MRI across surgical stages
  • Serial MRI across surgical stages

Main finding

As reported in the abstract

Nonacute ischemic white matter changes, focal tissue loss and ventriculomegaly more common in BDG and Fontan vs pre-BDG

P<0.05

Odds of brain injury (adjusted for surgical stage) decreased with increasing cerebral blood flow

63%-75%

Odds of ≥2 coexisting lesions decreased with increasing cerebral blood flow

44%

Observational data: associations, not effects.
