Abstrakt		Background. Ultrasound Doppler measurements can provide important and useful information about the uterine circulation in pregnant women with hypertension and fetal growth retardation. The aim of this prospective study was to assess the velocity of uterine artery blood flow and compare the current known pulsatility index (PI) and resistance index (RI) with the new parameter- the compliance index (CI). The purpose of the research was an early detection and prediction of fetal growth retardation and hypertension in pregnancy. The research was made on Gynecology and Obstetrics Department of General Hospital in Nova Gorica from June 1994 to October 1996 All pregnant women were informed of the purpose and joined the research voluntarily signing an informed consent. The research was approved by The Board for medical and ethical matters. Methods: A group of 80 randomly selected pregnant women with single pregnancy was included in the research. The group was at the end of study divided into normal and pathological. The normal group was composed of 44 pregnant women with normal pregnancy, and the pathological group of 36 pregnant women with hypertension and fetal growth retardation. Doppler measurements of the uterine artery were made in a period between 18th and 40th week of pregnancy. The position of the placenta was also taken into account. A comparison of the velocity of bload flow, the PI and RI and the CI was made. The fetal body weight was also assessed on the basis of ultrasound measurements of fetal parameters.

Izvleček		Izhodišča. Ultrazvočne meritve pretokov uterine arterije pri nosečnicah s hipertenzijo in zastojem plodove rasti nam lahko dajo koristne podatke o obtoku v maternici. V prospektivni raziskavi sem ocenjeval hitrosti pretokov uterinih arterij in primerjal doslej poznana količnika pulzatidnosti (PI) in upora (RI) z novim kazalcem - količnikom podajnosti (CI). Cilj raziskave je bil zgodnje odkrivanje in napovedovanje zastoja plodove rasti in hipertenzije v nosečnosti. Raziskava je narejena na ginekološko-porodniškem oddelku Splošne bolnišnice v Novi Gorici od junija 1994 do oktobra 1996. Vsem nosečnicam sem pojasnil namen raziskave, k raziskavi so pristopile prostovoljno in podpisale izjavo o "obveščenem pristanku". Razdskavo je odobrila Komisija za medicinsko etična vprašanja. Metode. Avtor je v raziskavo vključil 80 naključno izbranih nosečnic z enoplodno nosečnostjo. Izbrano skupino je na koncu raziskave razdelil na normalno in patološko. V normalni skupini je bilo 44 nosečnic z normalno nosečnostjo, v patološki skupini pa 3G nosečnic s hipertenzijo in zavrto plodovo rastjo. Meritve pretokov uterinih arterij so narejene od 18. do -40. tedna nosečnosti; upoštevana je lega posteljice; primerjane so hitrosti pretokov ter količniki pulzatilnosti; upora in podajnosti. Na osnovi ultrazvočnih meritev ploda je ocenjena tudi plodova telesna teža. Rezultati. Analiza splošnih podatkov med skupinama je pokazala statistično pomembno razliko v pojavljanju proteinurije, urgentnega carskega reza in 2,6-krat večje redativno tveganje za prirojene napake v patološki skupini. Meritve ploda in ocenitev telesne teže ploda so pokazale 87,5odstotno občutljivost in 96,9-odstotno specifičnost za odkrivanje zastoja plodove rasti. (Izvleček skrajšan pri 2000 znakih)
