Cerebral venous distention associated with cardiac failure in infants
Insights
Congestive cardiac failure in infants can cause specific CT scan findings in the brain's veins and sinuses. These changes may indicate venous congestive failure and raise the risk of sinus thrombosis.
Area of Science:
- Pediatric Radiology
- Cardiology
- Neurology
Background:
- Congestive cardiac failure (CCF) in infants presents unique diagnostic challenges.
- Understanding the impact of CCF on intracranial structures is crucial for early diagnosis and management.
Observation:
- Noncontrast cranial computed tomography (CT) in three infants with CCF revealed dilated and hyperdense intracranial veins and sinuses.
- These findings were observed despite the exclusion of intracranial venous thrombosis and arteriovenous malformation.
Findings:
- The observed CT pattern is hypothesized to be secondary to elevated central venous pressure resulting from cardiac failure.
- This suggests a potential imaging biomarker for venous congestive failure in infants.
Implications:
- This specific CT pattern should alert clinicians and radiologists to the possibility of venous congestive failure.
- It highlights the risk of subsequent sinus thrombosis in affected infants, necessitating vigilant monitoring and management.
Abstract:
Three infants with congestive cardiac failure demonstrated dilated and hyperdense intracranial veins and sinuses on noncontrast cranial CT. Intracranial venous thrombosis and arteriovenous malformation were excluded in two infants by autopsy and in one infant by MR imaging. We believe the CT findings were secondary to an elevated central venous pressure caused by the cardiac failure. This CT pattern suggests venous congestive failure, and it should alert the clinician and radiologist to the risk of subsequent sinus thrombosis.
