Pathophysiology of Incomplete Abortion

RisK Factors:

Precipitating Factor:

Fetal Factors:  Abnormal development of zygote

8 weeks AOG( occurs during 1st Trimester of Pregnancy)

Maternal Factors:  Infection  Systemic disease  Exposure to radiation  Reproductive system anomalies  Drug ingestion  Age Placental Factors:  Abnormal placental implantation  Premature separation of the normall implanted placenta

Implanted egg, slightly separates or tears from the uterus

Blood collects between the chorionic membrane( a membrane that develops around a fertilized egg) and the wall of the uterus

Blood leaks in the cervix

Mild uterine cramping on the lower abdomen with minimal vaginal spotting / bleeding ( 3-4 days )

Subchorionic hemorrhage

Severe subchorionic bleeding can lead to rupture of subchorionic membrane.

Disruption of blood flow, containing oxygen& nutrients to the developing fetus.

Fetus is compromised

subsequently expelled from the uterus

Patient now manifest signs and symptoms of a spontaneous abortion like:  Heavy vaginal flow  Severe uterine cramping  Open cervix  Passage of tissue  Ultrasound reveals the absence of a viable fetus

Risk for miscarriage and threatened abortion

Incomplete abortion

Ultrasound shows that some of the products of conception are still inside the uterus
