A 30-year-old woman with a bicorporeal uterus complained of abdominal pain and vaginal hemorrhage at 28 weeks and 5 days of gestation. There were no signs of placenta previa with echography in the second trimester; however, the echography showed a highly echoic area (91 × 85 mm), indicating placenta previa. Thereafter, abdominal pain and vaginal bleeding increased. Read More

Rationale: Pernicious placenta accrete (PPP) is an obstetrical complication associated with severe life-threatening hemorrhage, which is one of the leading causes of maternal mortality worldwide. Caesarean hysterectomy is the effective method to control intraoperative bleeding for this unscheduled high-risk patient. But a challenge for clinicians in this case is to determine the optimal timing of hysterectomy, because it will directly determine maternal outcome. Read More

Bleeding in late-term pregnancy can present as an innocuous start to parturition or a catastrophic maternal-fetal hemorrhage masked by the physiologic adaptations of pregnancy. The emergency management of late-term bleeding can be challenging, especially when providing stabilizing care in a limited-resource environment. Early recognition of life-threatening vaginal bleeding, potential causes, and emergency management of maternal-fetal distress is reviewed. Read More

Placenta accreta spectrum disorders, especially placenta percreta (PP) and placenta praevia (PLP), are major risk factors for massive obstetric haemorrhage which is a common cause of maternal morbidity and mortality in our environment. This risk becomes exponential and life-threatening when the two conditions co-exist in the same patient. Even in advanced countries with readily available expertise and state of the art resuscitative and supportive facilities, these conditions are associated with grave maternal and perinatal morbidity and mortality.

Here we reviewed the literature regarding an interesting new approach to treat type 2 vasa previa (VP). Vasa previa is a rare placental disorder in which fetal blood vessels, unsupported by underlying placenta, cross over the cervical internal os; type 1 vasa previa is attributed to a velamentous cord insertion near the cervix while type 2 vasa previa occurs when connecting vessels of a bi or multilobed placenta cross over internal cervical . To date, there have been 5 reported cases of fetoscopic laser ablation for the treatment of type 2 vasa previa between 22 and 33 weeks' gestation . Read More
