Role of ultrasound in early pregnancy in differentiating normal and abnormal pregnancies.
A prospective study was carried out from November 2006 - December 2008 in which a total of 304 patients with early pregnancy were examined by ultrasound (US). Of these, 203 (66.8%) cases were normal pregnancies (including 8 cases of twin pregnancy), 32 (10.5%) missed abortions, 19 (6.3%) incomplete abortions, 14 (4.6%) complete abortions, 12 (4.0%) blighted ovums, 11 (3.6%) without sonographic evidence of pregnancy, 7 (2.3%) ectopic pregnancies and 6 (1.9%) molar pregnancies. US in early pregnancy gave a reliable and accurate differentiation between a viable normal pregnancy and an abnormal/pathological pregnancy.
