- Placenta Increta- Varying degree of penetration of villi into muscle bundle
- Placenta Percreta- Penetration of villi in to serosal layer.
Management Partial morbid adherent placenta
- Adherent area is separated with finger
- Leaving behind the bit of placental tissue
- With inj. Oxytocin & Ergometrine-effective uterine contraction is achieved
- If uterus fails to contract- hysterectomy in parous women.
