Purpose: To investigate the possible risk factors which might increase the likelihood of
surgical evacuation after medical termination of pregnancy during the second trimester.
Methods: Data derived from 262 women who had undergone medical termination of
pregnancy during her second trimester in a tertiary care center between January 2009-
February 2013 were retrospectively analyzed. Misoprostol was administered vaginally at
intervals of 4-6 hours at a total dose of 100-4400 mg for medical termination.
Results: Surgical evacuation was performed at a rate of 19.8 percent (52/262). Indications for
surgical evacuation were incomplete abortion in 37, and failure of medical induction of
abortion in six patients. Total dose of misoprostol, time to abortion after induction, duration of
hospitalization, systolic blood pressure at admission and baseline hematocrit levels,
occurrence of side effects of misoprostol seem to increase the likelihood of a surgical
procedure for definite termination of a second- trimester pregnancy.
Conclusion: Both surgical evacuation as well as medical induction of abortion can be utilized
for termination of second- trimester pregnancies. Surgical evacuation should be considered in
case of failure of induction, incomplete abortion or for hemodynamically instable patients.
Correct and timely decision for the selection of an appropriate method is crucial to avoid
hazardous outcomes.
Key words: Second trimester; pregnancy; termination; surgical evacuation.

Material and Methods
At least 3% of pregnancies are affected by either a genetic or structural fetal anomaly, were retrospectively analyzed. The local and prenatal screening for anomalies is a trial. The study included patients treated in the obstetrics and gynecology department of a tertiary care center between January proportions ranging from 47% to 90% (2). Most diagnoses of genetic and structural and/or ultrasonography, and, consequently, of gestation were included in the analysis. patients wishing to terminate an anomalous These patients were admitted to our clinic fetus often do so in the second trimester. because of fetal abnormalities, and a dead Both medical and surgical evacuation can fetus. 67 patients were performed cesarean operation previously. Patients aged ≥18 years with a history of live fetuses were surgical evacuation performed during STP included in this study. Exclusion criteria ranges between 5 and 30% (1, 3, 4). There are few studies focusing on the possible severe asthma or coronary artery disease, and the presence of ectopic pregnancy or evacuation for termination of STP (1).
