Abstract:
Objective:To investigate clinical characteristics and high-risk factors of prognosis of twin-to-twin transfusion syndrome(TTTS) combined with necrotizing enterocolitis(NEC).Methods:The clinical data of 102 children with TTTS admitted to the NICU at the Third Affiliated Hospital of Zhengzhou University from January 2017 to January 2020 were collected.Fifty-one pairs(102 cases)of twins without TTTS who were hospitalized at the same time and in the same gestational age were selected as the control group, and the relevant case data were collected and compared.The clinical data of 14 children with NEC in TTTS group were analyzed retrospectively.Results:(1)The average gestational age of TTTS group was(32.24±2.12)weeks, and that was (32.47±1.84) weeks in control group, with no statistical significance( P>0.05). The average birth weight of TTTS group was(1 547.63±523.80)g, which was lower than that of control group(1 658.71±454.13)g( P<0.05). There were 14 children in TTTS group with NEC, with an incidence of 13.7%(14/102), and seven children in the control group with NEC, with an incidence of 6.9%(7/102)( P<0.05). The proportion of very low birth weight infants, NEC occurrence within 2 weeks and mortality in TTTS group were higher than those in control group( P<0.05). (2)Compared with the non-NEC group, the NEC group of TTTS children had lower birth weight, the incidence of intrauterine distress and severe postnatal asphyxia, and the rate of sepsis were significantly higher than those in non-NEC group( P<0.05). (3)Among TTTS children, NEC was diagnosed in ten donors(71.4%) and four recipients(28.6%), with statistically significant difference between two groups( P<0.05). (4)The early clinical symptoms of TTTS complicated with NEC were mainly bloody stools, abdominal distension, poor response, apnea, and vomiting. Conclusion:TTTS is one of the risk factors for NEC, which the occurrence time of TTTS combined with NEC is not completely consistent with the classic NEC, which is more likely to occur within 2 weeks after birth.Children with TTTS complicated with NEC mostly occur in donor infants, and fetal distress in utero, severe asphyxia and sepsis are the high risk factors.The early clinical symptoms of TTTS combined with NEC are not significantly different from those of common NEC, mainly including bloody stools, abdominal diste, poor response, apnea, and vomiting.Vigilance should be raised when similar digestive symptoms appear in children.
