LOCATION OF THE PLACENTA IN PATIENTS WITH GESTATIONAL HYPERTENSION

Abstract

Data on the relationship of the location of the placenta and gestational hypertension is very limited. Objective: to study the location of the placenta and, depending on its location, compare baseline indicators in pregnant women with gestational hypertension in the second trimester. 104 women were examined in the period of 20-26 weeks of pregnancy. The control group consisted of 22 women comparable with the main group. An obstetric history was collected, a physical examination of the patients was performed, a body mass index (BMI) was calculated, and an ultrasound examination (ultrasound). Gestational hypertension was defined as blood pressure >140/90 mmHg. According to the anamnesis, 18.3% of patients in the main group had a positive family history of hypertension. The age of the surveyed pregnant women ranged from 20 to 34 years. The groups were comparable in age, and in both groups the largest number of patients were in the age group of 30-34 years. Obesity was diagnosed in 49.0% of cases in the main group and in 40.9% of cases in the control group. In the group with gestational hypertension, the anterior position of the placenta was visualized in 44.2% of patients, the posterior position in 38.5% and the lateral position in 17.3% of patients. The mean age of patients with lateral placenta was significantly higher compared with anterior placenta (p=0.052) and posterior placenta (p=0.053). With a lateral location of the placenta, patients of the older age group accounted for 72.2%, which is higher than with the posterior location of the placenta (p=0.055). The lateral location of the placenta was statistically less common in the age group of 25-29 years compared with the posterior placenta (p=0.047). With the lateral placenta, there was a high SBP compared with the anterior localization (p=0.030). It is recommended to monitor women with a lateral placenta during the entire period of pregnancy.
