Other specified abnormal products of conception (OSAPC) is a term used to describe pregnancy losses that do not fit into the categories of miscarriage or ectopic pregnancy. OSAPC refers to any abnormal tissue or fetus that is expelled from the uterus during pregnancy and is not a viable pregnancy. Examples of OSAPC include a molar pregnancy, a blighted ovum, and a partial molar pregnancy.
A molar pregnancy occurs when there is an abnormal growth of cells in the uterus that usually develops into a placenta. Instead of a healthy placenta, the growth forms a mass of abnormal cells that look like clusters of grapes. Most molar pregnancies are benign, but some may develop into a cancerous growth. A molar pregnancy can be detected through an ultrasound and is usually treated by a D&C procedure to remove the abnormal tissue.
A blighted ovum occurs when a fertilized egg implants in the uterus but fails to develop into an embryo. The gestational sac is empty, and there is no visible fetal pole or heartbeat. A blighted ovum usually results in a miscarriage, and the tissue is expelled from the uterus. The cause of a blighted ovum is unknown, but it is thought to be due to chromosomal abnormalities.
A partial molar pregnancy occurs when there are too many chromosomes in the fertilized egg. The extra genetic material leads to the development of abnormal placental tissue and a fetus that is not viable. A partial molar pregnancy can be detected through an ultrasound, and the treatment is usually a D&C procedure to remove the abnormal tissue. In rare cases, a partial molar pregnancy can develop into cancer.
Other specified abnormal products of conception are pregnancy losses that do not fit into the categories of miscarriage or ectopic pregnancy. Examples of OSAPC include a molar pregnancy, a blighted ovum, and a partial molar pregnancy. These conditions are detected through ultrasound and are usually treated by a D&C procedure to remove the abnormal tissue. If you experience any symptoms of a pregnancy loss, it is important to speak with your healthcare provider for guidance and support.
