Antepartum haemorrhage

In obstetrics, antepartum haemorrhage (APH), also prepartum hemorrhage, is bleeding from the vagina during pregnancy from twenty four weeks gestational age to term.

It should be considered a medical emergency (regardless of whether there is pain) and medical attention should be sought immediately, as if it is left untreated it can lead to death of the mother and/or fetus.

It can be associated with reduced fetal birth weight.cite journal |author=Lam CM, Wong SF, Chow KM, Ho LC |title=Women with placenta praevia and antepartum haemorrhage have a worse outcome than those who do not bleed before delivery |journal=Journal of obstetrics and gynaecology : the journal of the Institute of Obstetrics and Gynaecology |volume=20 |issue=1 |pages=27–31 |year=2000 |pmid=15512459 |doi=10.1080/01443610063417]

Bleeding without pain is most frequently bloody show, which is benign; however, it may also be placenta previa (in which both the mother and fetus are in danger). Painful APH is most frequency placental abruption.

Differential diagnosis of APH

* Bloody show (benign) - most common cause of APH
* Placental abruption - most common pathological cause
* Placenta previa - second most common pathological cause
* Vasa previa - often difficult to diagnose, frequently leads to fetal demise
* Uterine rupture
* Bleeding from the lower genital tract
** Cervical bleeding - cervicitis, cervical neoplasm, cervical polyp
** Bleeding from the vagina itself - trauma, neoplasm
* Bleeding that may be confused with vaginal bleeding
** GI bleed - hemorrhoids, inflammatory bowel disease
** Urinary tract bleed - urinary tract infection
