Only 50\u201360% of all conceptions fail to survive 20 weeks of gestation. It is estimated that about 75% of all unsuccessful conceptions are due to failed implantation and are not reported as spontaneous abortions.<\/jats:p>\n               <jats:p>\n                  <jats:italic>Material and Methods:<\/jats:italic> We performed a prospective observational study at the Department of Obstetrics and Gynecology of the Medical University Plovdiv between October 2014 and September 2015. We studied two groups of pregnant women: women with threatened abortion and those with normal pregnancy. All women underwent a transvaginal ultrasound evaluation of the uterine arterial blood flow. We measured peak systolic and end-diastolic velocity and calculated the average IR (resistance index) and S \/ D (systolic to diastolic ratio).<\/jats:p>\n               <jats:p>\n                  <jats:italic>Results:<\/jats:italic> There was no association between pregnancy outcome and the mean difference between uterine arterial IR and S \/ (P &gt; 0.05).<\/jats:p>\n               <jats:p>\n                  <jats:italic>Conclusion:<\/jats:italic> In our study, Doppler ultrasound could not differentiate between women at risk for miscarriage and normal women. Further studies are necessary to answer this question.<\/jats:p>","DOI":"10.1515\/prilozi-2016-0007","type":"journal-article","created":{"date-parts":[[2016,7,18]],"date-time":"2016-07-18T08:14:59Z","timestamp":1468829699000},"page":"51-56","source":"Crossref","is-referenced-by-count":1,"title":["Doppler velocimetry of the uterine arteries: an early screening test for miscarriage"],"prefix":"10.1515","volume":"37","author":[{"given":"Ilian","family":"Trayanov","sequence":"first","affiliation":[{"name":"UMBAL St. George \u2013 Plovdiv, Department of Obstetrics and Gynecology, Chair of Obstetrics and Gynecology, Plovdiv, R.
