Value of routine transvaginal ultrasound scan in women requesting early termination of pregnancy

This was a retrospective study of 140 women attending a termination clinic from 1 April 2002 to 31 March 2003. All women had a transvaginal ultrasound scan. Of 140 women, 56 women benefited from the scan; 26.7% had non-viable pregnancy, 35.71% did not remember their LMP, 12.5% had discrepancy between the scan and LMP. Incidental findings were noted in 24.6% of which two had a twin gestation, nine had ovarian cysts, one had an ectopic pregnancy, one had a hydatidiform mole, one conceived with an IUCD and one had a bicornuate uterus with pregnancy in one horn. Two of the nine women with ovarian cysts needed a laparotomy. This study concludes that routine transvaginal scan (TVS) scan is an essential investigation for proper assessment of all women requesting termination of pregnancy. TVS is a safe and effective procedure which provides useful information regarding gestational age, viability of pregnancy and uncertain dates. In cases of the ectopic pregnancy and the hydatidiform mole transvaginal ultrasound helped us in appropriate management from the outset and minimised complications.
