The predictive value of three-dimensional Doppler ultrasonography in determining implantation in patients underwent in vitro fertilization

Özet

Objective: The aim of this study is to evaluate the relationship between endometrial and sub-endometrial blood flow and implantation rate in patients whose undergone in vitro fertilization.Methods: A prospective study was conducted. Long protocol and antagonist regimens were administered to the patients. Endometrial and sub-endometrial blood flow was evaluated by using 3 dimensional Doppler ultrasonography on the day of oocyt retrieval measurement. For comparison pregnant and non-pregnant women in terms of endometrial and sub-endometrial blood flow, t test was used. The p value was considered statistically meaningful as <0.05.Results: Endometrial and sub-endometrial blood flow was not different between pregnant and non-pregnant women in both groups (p>0.05). In long protocol group, the number of embryo was greater in pregnant women than non-pregnant women (p=0.012). The number of transferred embryo increased pregnancy rate almost 3.5 fold (p=0.002).Conclusion: The endometrial and subendometrial blood flow is not reliable factor in prediction pregnancy or implantation.Key words: Doppler ultrasonography, in vitro fertilization, pregnant women

Abstract

Objective: In this study, it was aimed to compare the sensitivity of diagnostic tests in patients with a preliminary diagnosis of brucellosis.Methods: We have compared the serological methods, standard tube agglutination test (STA), Coombs Test (CT), Rose Bengal (RBT), and the gel centrifugation test. In patients with a preliminary diagnosis of brucellosis, subjects with a positive test result of RBT has been included in the research and other diagnostic tests STA, CT and Coombs Gel centrifugation tests were performed within the range of same titration.Results: Total 132 patient’s serums were studied. In RBT positive 92 patients’ serums, negative test results were found in 11 with STA, in 9 with CT and in 6 with gel test. While 35 patients were identified to be positive by using Brucella gel test at 1/5120 titer, no positive test results were seen with STA and CT at the same titer. Generally, CT results were one titration below the gel centrifugation test results.Conclusion: In conclusion, RBT and STA were not always adequate to determine the diagnosis of brucellosis. Low titer STA results should be supported by tests such as CT or gel centrifugation and the seroconversion must be monitored. Due to giving fast results, gel centrifugation test can be preferred in diagnosis of Brucellosis.Key words: Brucellosis, gel centrifugation, Coombs test
