Abstract:
Objective To explore the effect of blood oxygen saturation on the hemodynamics in fetuses with complete transposition of the great artery ( CTGA ) without outflow tract obstruction in the second trimester of pregnancy . Methods The brain biometry and hemodynamics parameters were retrospectively analyzed in 38 fetuses with CTGA from multiple medical centers .All the fetuses with CTGA were divided into two groups ,ventricular septal defect ( VSD) group( 14 cases) and no VSD group( 24 cases) according to the VSD . Twenty-four gestational age (GA)-matched fetuses were chosed as control group . The biparietal diameter (BPD) and head circumference ( HC) ,pulsatility indexes ( PI) in the middle cerebral artery (MCA) and the umbilical artery ,the cerebroplacental ratio (CPR) were compared among different groups . Results There were no significant differences in GA ,BPD ,HC ,MCA-PI ,UA-PI and CPR among control group ,CTGA with VSD group and CTGA without VSD group in the second trimester of pregnancy ( P ＞0 .05) . Conclusions The altered oxygen saturation of the cerebral circulation in CTGA does not affect the brain biometry and hemodynamics in fetuses in the mid-gestational age .
