BACKGROUND The global burden of postpartum hemorrhage (PPH) in women with placenta previa is a major public health concern. Although there are different reports on the incidence of PPH in different countries, to date, no research has reviewed them. OBJECTIVE The aim of this study was to calculate the average point incidence of PPH in women with placenta previa. METHODS A systematic review a...

BACKGROUND To determine whether patients with placenta previa who delivered preterm have an increased risk for recurrent spontaneous preterm birth. METHODS This retrospective population based cohort study included patients who delivered after a primary cesarean section (n = 9983). The rate of placenta previa, its recurrence, and the risk for recurrent preterm birth were determined. RESULTS ...

Placenta previa totalis can cause life-threatening massive postpartum hemorrhage, and careful anesthetic management is essential. Preventive uterine artery embolization (UAE) before placental expulsion was introduced to reduce postpartum bleeding in cases of placenta previa totalis. We describe the case of a 40-year-old woman (gravida 0, para 0) with placenta previa totalis and uterine myomas w...

Placenta percreta is one of the most serious complications of placenta previa and is frequently associated with severe obstetric hemorrhage usually necessitating hysterectomy. We present a case of placenta previa percreta diagnosed by ultrasound and magnetic resonance imaging techniques, in which we accomplished conservative management of postpartum hemorrhage. The management we propose include...

The "lean" umbilical cord (also known as thin-cord syndrome) is a comparatively rare anomaly of the umbilical cord, which has seldom been described in the medical literature. We report on a 35-year-old women who presented to us at 29 + 4 weeks gestation with vaginal bleeding and cervical incompetence subsequently complicated not only by premature rupture of membranes but also acute placental in...

Placenta previa is a condition derived to an abnormal implantation of the embryos in the lower uterine segment, a place that predisposes to persistent uterine bleeding because of the development of new vessels and because it is a poorly contractile area of the uterus. Risk factors for placents previa are: maternal age, number of pregnancies, cigarette smoking, multiple pregnancies, previus surg...

Perinatal arterial ischemic stroke (AIS) is estimated to occur in 1/1600 to 1/5000 births [1]. Even if rare, it is an important cause of mortality and morbidity in neonates. A meta-analysis showed that 57% of infants who suffer perinatal AIS develop motor and/or cognitive deficits, and 3% die [2]. Risk factors proposed for perinatal AIS include maternal prothrombotic conditions and pre-eclampsi...

Correspondence To the Editor: I reviewed the article Quantification of adventitial vasa vasorum (VV) vascularization in double‑injury restenotic arteries by Meng et al. with great interest, which described their experiment about adventitial VV and postangioplasty restenosis. Percutaneous transluminal angioplasty is now widely used for the treatment of atherosclerotic lesions in various arteries...

BACKGROUND The autologous saphenous vein is the most common conduit for coronary artery bypass grafting, but the vein graft disease will occur. This study used Matrigel basement membrane matrix with many different growth factors to promote vasa vasorum neovascularization and extenuate the hypoxia to improve remodeling. METHODS This study observed the hypoxia and thickness of the vein grafts a...
