A 20-year-old primigravida at 12 weeks of gestation complains of spotting per vaginum. On examination uterine size corresponds to gestational age and cervical os appears closed. What is your diagnosis?: (A) Inevitable aboion, (B) Threatened aboion, (C) Complete aboion, (D) Incomplete aboion
Answer is B. The clinical diagnosis of threatened aboion is presumed when bloody vaginal discharge or bleeding appears through a closed cervical os during the first 20 weeks. Uterus corresponds to the gestational age. Transvaginal sonography is used to locate the pregnancy and determine if the fetus is alive.Reference: William's Obstetrics; 25th edition; Chapter 18; Aboion
