Abstract:

Objective To analyze the clinical characteristics and outcomes of newborns delivered bywomen after renal transplantation, and to evaluate the associated risk factors and the effectiveness of management strategies. Methods A retrospective analysis was conducted on the clinical data of 4 female patients who successfully conceived and delivered after allogeneic renal transplantation between December 2023 and January 2025. Results All four patients conceived 5 ~ 12 years post-transplantation and delivered via cesarean section. Major maternal complications included preeclampsia (4 cases,2 severe), anemia (4 cases,3 moderate,1 mild), chronic hypertension (2 cases), gestational diabetes mellitus (1 case), and fetal growth restriction (1 case). Gestational age at delivery ranged from27 to 37+3 weeks, with 3 preterm births (2 extremely preterm) and 1 term birth. Birth weights ranged from 700 ~3 280 g (2 very low birth weight,1 extremely low birth weight). Three infants were appropriate for gestational age and one was small for gestational age. Major neonatal complications included neonatal respiratory distress syndrome (4 cases),bronchopulmonary dysplasia (2 cases), neonatal sepsis (2 cases), mild neonatal asphyxia (2 cases), hemodynamically significant patent ductus arteriosus requiring surgery (1 case), pneumothorax (1 case), neonatal hypoglycemia (1 case), and neonatal hypothyroidism (1 case). All four newborns survived after intensive neonatal care and showed favorable growthand development at the 6-month follow-up. Conclusion Pregnancy after renal transplantation is at high-risk, withsignificant maternal and neonatal morbidity, particularly in patients with preterm birth, preeclampsia, and anemia. However,favorable neonatal outcomes can be achieved through rigorous pre-pregnancy evaluation, optimized multidisciplinary antenatal management, and timely, targeted neonatal interventions.

摘要:

目的 探讨肾移植术后妊娠患者及所分娩新生儿的临床特点、结局及其相关风险因素,评估孕期管理和产后干预策略的有效性。方法 回顾性分析 2023 年 12 月至 2025 年 1 月天津市第一中心医院收治的4 例同种异体肾移植术后成功妊娠并分娩的患者及其新生儿的临床资料。结果 4 例患者均于肾移植术后 5 ~12 年首次妊娠,均行剖宫产终止妊娠。孕期主要并发症包括 :子痫前期(4 例次,其中重度 2 例)、贫血(4 例次,中度 3 例次、轻度 1 例次)、慢性高血压(2 例次)、妊娠期糖尿病(1 例次)、胎儿宫内生长受限(1 例次)。 分娩孕周 27 周至 37+3 周,早产 3 例次(超早产 2 例次),足月产 1 例次 ;新生儿出生体重 700 ~ 3 280 g(极低出生体重儿 2 例次,超低出生体重儿 1 例次),3 例次为适于胎龄儿,1 例次为小于胎龄儿。新生儿主要并发症:新生儿呼吸窘迫综合征(4 例次)、支气管肺发育不良(2 例次)、新生儿败血症(2 例次)、新生儿轻度窒息(2 例次)、动脉导管未闭(1 例次,需手术)、新生儿气胸(1 例次)、新生儿低血糖症(1 例次)、新生儿甲状腺功能减退(1 例次)。4 例新生儿经积极救治后均存活出院,随访 6 个月生长发育良好。结论 肾移植术后妊娠属高危妊娠,母儿并发症发生率高,尤其是早产、子痫前期和贫血。尽管如此,通过严格的孕前评估、优化的孕期多学科管理及新生儿科及时的针对性救治,可以有效改善新生儿结局。
