The present study aims to measure the role of Doppler waveforms in pregnancy-induced hypertension (PIH) and its relationship with the perinatal outcome. MethodsWe have studied 50 pregnant women with PIH with gestational age (GA) 30-40 weeks for Umbilical Artery (UmA), Middle Cerebral Artery (MCA) and Uterine Artery (UtA) Doppler waveforms. Comparison between the various Doppler indices, i.e., Pulsatility Index (PI), Resistive Index (RI) and S/D ratio, with the severity of the disease and the perinatal outcomes were evaluated using appropriate statistical tests considering a threshold value of p-value <0.05 as significant. The Statistical Package for the Social Sciences (SPSS) version-16 (SPSS Inc, Chicago, USA) and MedCalc software (MedCalc Software Ltd, Ostend, Belgium) were used for data analysis. ResultsHalf (50%) of the cases attributed to the 26 to 30 years age group were at 38 to 40 weeks of gestation. Out of the 50 patients, 68% were primigravida, and 74% had severe PIH. Mean UmA PI, mean MCA PI, mean MCA RI, and mean Cerebro Placental Ratio (CPR) were differed significantly among mild and severe PIH patients (p-value<0.05). Perinatal outcomes in 33 (66%) cases were adverse. The abnormal UmA RI, MCA RI, MCA PI, MCA S/D were significantly linked with poor pregnancy outcomes (p-value <0.05). PIH cases with the presence of early diastolic notch of UtA (p-value <0.01), abnormal PI CPR (p-value <0.001) and S/D CPR (pvalue <0.003) were observed to have more adverse outcomes. PI CPR had the highest sensitivity (84.8%), and the existence of early diastolic notch of UtA and MCA-PI were most specific in diagnosing adverse perinatal outcomes. ConclusionCPR-PI is a valuable indicator of adverse perinatal outcomes in PIH. Doppler studies of multiple vessels may help manage high-risk pregnancies as it may provide helpful information about the fetus at risk of hypoxia and placental insufficiency.
Objectives Placenta previa is characterised as the placenta implant in the lower uterine segment, wholly or partially covering the internal os. Uterine scars from surgical operations are a potential factor of placenta previa. The present study aims to estimate the role of ultrasound in determining the incidence of placenta previa in the scarred and unscarred uterus. Also, it aims to evaluate the types of placenta previa in the scarred and unscarred uterus. Methods This hospital-based, prospective, observational study was performed from September 2021 to August 2022 among patients referred to the Department of Radiology, Fakhruddin Ali Ahmed Medical College and Hospital (FAAMCH), Barpeta, Assam. Written informed consent was obtained from the subjects. Transabdominal and transvaginal ultrasonography methods were used to assess placenta previa. The data analysis was performed using Statistical Package for the Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY) considering a p-value < 0.05 as significant. Results Out of the 517 subjects with bleeding per vagina, 41 (7.9%) were diagnosed with placenta previa by ultrasonography. The mean maternal age was 27.80 ± 5.36 years, and the most prevalent age group was 20-24 years (31.71%). The majority (70.73%) of cases had scarred uterus. The most prevalent placental position was fundo-body anterior. Complete placenta previa was present in 26% of the total cases in the present study. Conclusion The incidence of placenta previa in the scarred uterus was higher than that of the unscarred uterus. The high prevalence of placenta previa in women with scarred uterus necessitates improved monitoring and management to avoid disastrous outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
