Presentation of twins in Der Rosengarten ("The Rose Garden"), a German standard medical text for midwives published in 1513. In obstetrics, the presentation of a fetus about to be born specifies which anatomical part of the fetus is leading, that is, is closest to the pelvic inlet of the birth canal.
Fetal abnormalities are conditions that affect a fetus or embryo, are able to be diagnosed prenatally, and may be fatal or cause disease after birth. They may include aneuploidies, structural abnormalities, or neoplasms. Acardiac twin; Achondrogenesis; Achondroplasia
Prior to the arrival of C/S the fetus usually died during protracted labor and the mother's life was at risk as well due to infection, uterine rupture and bleeding. On occasion, if the baby was macerated and small, it collapsed sufficiently to be delivered. The shoulder presentation was a feared obstetrical complication.
The main causes of obstructed labour include a large or abnormally positioned baby, a small pelvis, and problems with the birth canal. [2] Both the size and the position of the fetus can lead to obstructed labor. Abnormal positioning includes shoulder dystocia where the anterior shoulder does not pass easily below the pubic bone.

Products of conception, abbreviated POC, is a medical term used for the tissue derived from the union of an egg and a sperm. It encompasses anembryonic gestation (blighted ovum) which does not have a viable embryo. In the context of tissue from a dilation and curettage, the presence of POC essentially excludes an ectopic pregnancy.
Hydatidiform moles are abnormal conceptions with excessive placental development. Conception takes place, but placental tissue grows very fast, rather than supporting the growth of a fetus. [12] [13] [14] Complete hydatidiform moles have no fetal tissue and no maternal DNA, as a result of a maternal ovum with no functional DNA.

In obstetrics, asynclitic birth, or asynclitism, refers to the malposition of the fetal head in the uterus relative to the birth canal. [1] Many babies enter the pelvis in an asynclitic presentation, but in most cases, the issue is corrected during labor. [2] Asynclitic presentation is not the same as shoulder presentation, where the shoulder ...
