Normal placenta spherical or round shape weighing approximately 500 grams and an average diameter of 15-20 cm with a thickness of about 2.5 cm
First: severe deformity and placenta
If the placenta is found to have excess weight, usually found in women with diabetes mellitus or a mother who suffered from syphilis
If less, or nearly 1/9 weight infants, usually found in women with heart disease or kidney
For the deformity can be divided into;
1. With multiple lobes, can occur in the placenta and placental tripartite duplex
2. Placenta fenestrata, which has a hole or window
3. Horse shoe placenta, shaped like a horse shoe
4. Membranasea placenta, with a very thin and wide form
5. Anularis placenta, placental ring-shaped
6. Suksenturiata placenta, if the main placenta contained a smaller placenta in addition to or separated by membranes
7. Spuria placenta, if there are two placentas are not related by blood vessels
8. Sirkumvalat placenta, which has a white ring on the edge of the placenta, decidua from entering between the membranes
Second: the disease in the placenta
1. Placental infarction, a placenta that has a small hard white tissue up to several centimeters on the surface of the maternal and fetal
2. Placental calcification, occurs when the placenta is too old, then there calcium accumulation in the basal layer of decidua, especially in places around the embedded villi and place terjedi fibrin degeneration
3. Tumor of the placenta, the placenta is divided again into cysts, fibromata, miksifibromata, hemangioma and korioangioma
4. Plasentitis or chorioamnionitis, which is an infection of the placenta, chorion, and amnion caused by the examination in which repeated
5. Placental insufficiency, the inability of the placenta in sufficient oxygenation, nutrients, excretion, and hormones to the fetus
Third: Abnormalities of the Umbilical Cord
Abnormalities of the umbilical cord insertion
Normal insertion (planting) the umbilical cord in the middle of the placenta
Bailedore placenta: umbilical cord insertion at the edge of the placenta
Velamentous insertion: insertion of the umbilical cord is located on the membranes lining
Length of the umbilical cord abnormalities
The length of the average umbilical cord is 55 cm, if the bias is too short causing placental abruption, whereas if too long can cause the coil cord to cause the death of the fetus.
