Đặc điểm lâm sàng, cận lâm sàng các trường hợp thai chậm phát triển trong tử cung từ 37 tuần tại Bệnh viện Phụ sản Hà Nội

Intrauterine growth restriction (IUGR) poses a substantial challenge in obstetrics due to its association with adverse perinatal outcomes, including increased risks of stillbirth and neonatal morbidity. Despite its critical impact, the diagnosis and management of IUGR remain complex, with ongoing debates regarding optimal criteria and interventions. There is a pressing need for effective strategies to identify IUGR cases early and monitor fetal well-being closely to determine the appropriate timing for delivery. This study aims to contribute to this understanding by describing the clinical characteristics and paraclinical characteristics of IUGR cases identified from 37 weeks gestation at Hanoi Obstetrics and Gynecology Hospital, thereby providing valuable insights for clinical practice in Vietnam.

This retrospective cross-sectional descriptive study investigated the clinical and paraclinical characteristics of 139 pregnant women diagnosed with intrauterine growth restriction (IUGR) from 37 weeks of gestation at Hanoi Obstetrics and Gynecology Hospital. The research aimed to provide essential insights into late-onset IUGR, a condition demanding careful diagnosis and management. Key findings revealed a mean maternal age of 29.69 ± 5.8 years, with most mothers falling within the 20-34 age bracket. The average gestational age at delivery was 38.09 ± 0.73 weeks, and the mean birth weight was 2310 ± 145.5 grams. Importantly, the majority (90.6%) showed normal fetal monitoring patterns, while only 9.3% exhibited abnormal fetal heart rates. Furthermore, the cerebroplacental ratio was ≥ 1 in 96.4% of cases, and the incidence of oligohydramnios was low at 6.5%. The study confirmed that ultrasound findings accurately reflect the fetal condition in IUGR cases, with the cerebroplacental ratio proving to be a strong indicator of chronic hypoxia, especially for severe IUGR (below the 3rd percentile). These results underscore the critical importance of timely detection and thorough in-utero fetal status assessment to optimize the timing of delivery, aiming to improve perinatal outcomes. The consistency of these findings with other regional and international studies reinforces their relevance for clinical practice and highlights the ongoing need for improved management protocols for IUGR.
