Major complications
Neurological complications
One case of stroke (1.44%) occurred in a male neonate aged 30 days and
weighing 3Kg, with severe HAA and VSD, admitted to our pediatric intense
care unit in a state of cardiogenic shock. His hemodynamics improved
upon inotropic medication, and surgery was performed 24 hours
post-admission, consisting of complete reconstructive aortoplasty and
VSD closure. CPB lasted 181 minutes, aortic clamping 90 minutes, and
CCMSP of 55 minutes. After weaning from CPB failed, the neonate was
placed on central extracorporeal membrane oxygenation (ECMO), and then
withdrawn from ECMO after 7 days. Thereafter, the infant displayed
marked global developmental delay, brain imaging revealing ischemic and
hemorrhagic lesions in the frontal and occipital regions.
Renal complications
Two (2.89%) neonates developed transient renal failure requiring
dialysis with patients’ characteristics listed in Table 4. They weighed
less than 3kg underwent total reconstruction for HAA and concomitant VSD
with CPB for over 150 minutes. Durations of CCMSP were 42 and 46
minutes.
No myocardial or visceral ischemia complications were observed in our
study.
