Uterine arteriovenous malformation is a rare disorder that can cause sudden life-threatening vaginal bleeding. ⋯ The use of office gynecologic ultrasound in combination with other imaging techniques is an important tool in the diagnosis and localization of uterine arteriovenous malformation. Embolization of supplying arteries is considered a safe and effective therapeutic option due to advances in radiologic intervention techniques. Advantages of this procedure include a minimally-invasive technique, low morbidity and preservation of uterine function.

Observational Study
[Second stage of labor: Does accelerations matter?].
Accelerations role during the second stage of labor has not been studied and current classification system NICHD downplays its presence. The objective of this study is to determine validity for acidemia detection of the loss of accelerations during the second stage of labor. ⋯ The absence of accelerations during the second stage of labor shows a bigger validity for neonatal acidemia than the presence of a category II tracing.

Obstetric hemorrhage is the leading cause of maternal mortality, responsible of 143,000 deaths every year. Thromboelastography is a tool that allows measuring the viscoelastic, dynamic and global properties of the blood, offering valuable information of coagulation alterations and help to guide early goal directed transfusional therapy. The purpose of this review is to evaluate the evidence of this tool in obstetric hemorrhage and the management of the associated coagulopathy.
