Summary
Infant venous thrombosis after cardiac catheterization is higher than expected, particularly in lower-weight infants. Prolonged catheter dwell time and infection increase thrombosis risk.
Area of Science:
- Pediatric Cardiology
- Vascular Medicine
- Interventional Radiology
Background:
- Post-catheterization venous thrombosis is a complication in infants undergoing cardiac procedures.
- Understanding risk factors is crucial for preventing adverse outcomes.
Purpose of the Study:
- To investigate factors influencing the rate of venous thrombosis following cardiac catheterization in infants.
- To identify specific risk factors associated with increased thrombosis incidence.
Main Methods:
- Retrospective study of 180 infants under one year of age undergoing cardiac catheterization.
- Assessment of thrombosis at repeat catheterization on the ipsilateral side.
- Analysis of various potential influencing factors including weight, catheter dwell time, and infection.
Main Results:
- Overall thrombosis frequency was 15.6%, higher than previously reported.
- Thrombosis rate increased significantly with decreasing infant weight.
- Indwelling femoral vein catheters left for >24 hours and infection were associated with increased thrombosis.
- Age, cardiac malformation type, cyanosis, operation timing, catheterization duration, and technique (percutaneous vs. cutdown) did not influence thrombosis rate.
Conclusions:
- Infant weight, prolonged catheter dwell time, and infection are significant risk factors for post-catheterization venous thrombosis.
- A notable proportion of thromboses involved the vena cava, potentially missed by contralateral catheterization.
- Early identification and management of these risk factors are essential in pediatric cardiac interventions.
