Evaluated comparison of transvaginal and abdominal ultrasound in diagnosis of ectopic pregnancy
Main Article Content
Abstract
SUMMARY
Purpose: To compare the value of abdominal and transvaginal ultrasound in diagnosis of ectopic pregnancy.
Materials and methods: Cross-section and descriptive study was underwent on 140 patients who were suspected of ectopic pregnacies, from June 2009 to June 2010. All of them were done both abdominal and transvaginal ultrasound. The value of each modality was analysed base on gold standard of histopathology.
Results: 140 cases of suspected ectopic pregnancy in which 110 were ectopic pregnancies, 10 viable intrauterine pregnancies, 19 abortions and 1 hydatidiform mole. The suggestive abdominal ultrasound diagnosis of ectopic pregnancy has Sn 71%, Sp 86%,
PPV 95% and NPV 44%, those of transvaginal ultrasound has Sn 92.7%, Sp 96.6%, PPV 98% and NPV 96,6%.
Conclusion: Transvaginal ultrasound has a primary role in the
diagnosis of ectopic pregnancy.
