Valoarea predictivă a indicilor Doppler ai arterei uterine la 11-14 săptămâni pentru complicaţiile hipertensive ale sarcinii

Introduction. Hypertensive complications of pregnancy can often lead to serious, even life-threatening situations for the mother and fetus. First-trimester uterine artery Doppler can be a predictive tool for such complications. Materials and method. At the Department of Obstetrics and Gynecology of the Arad County Emergency Clinical Hospital, we examined 305 pregnant patients, from 11 weeks to 13 weeks+6 days gestational age, by ultrasound, both as inpatients and outpatients, and we have assessed the evolution of their pregnancy. Results. There were 21 patients with hypertensive pregnancy complications (6.89%) and 284 patients with normal outcome (93.11%). Three patients had pregnancy-induced hypertension (0.98%), and 18 had preeclampsia (PE; 5.9%), with 12 cases of mild PE (3.95%) and six cases of severe PE (1.97%). The sensitivity for uterine artery PI above the 95th percentile, for uterine artery RI above the 95th percentile, and for uterine artery PI/RI above the 95th percentile was 0%, 0-33.33% and 0%, respectively. The specificity was 94.72-95.03%, 94.98-95.42% and 94.98-95.03%, respectively. The positive predictive value was 0%, 0-13.33% and 0%, respectively. The negative predictive value was 92.76-98.97%, 93.45-99.31% and 92.76-98.97%, respectively. Odds ratios were 0.453-3.966, 1.147-10.286 and 0.453-3.966, respectively. Conclusions. Uterine artery Doppler indices above the 95th percentile during the 11-14 week gestational age offers low to medium detection rates, the best index being the resistivity index.
