“…Because the entire fetal cardiac output passes through the cord, it can take less than 10 min for total exsanguination of the fetus to occur. If cesarean delivery is accomplished immediately, good neonatal outcome can be obtained by aggressive postnatal transfusion [2]. In our case, there was only a small abrasion of one of the vessels and no actual rupture of the vessel (Fig.…”

“…Catanzarite and colleagues 25 reported a specificity of 91% for the sonographic diagnosis of vasa previa. They could not ascertain the sensitivity of ultrasonographic diagnosis of vasa previa because they did not have outcomes data for all pregnancies they scanned.…”

Introduction:Vasa previa is an uncommon obstetrical complication that poses a high risk of fetal demise if not recognized before rupture of membranes. It is vital that providers recognize risk factors for vasa previa and diagnose this condition before the onset of labor so that fetal shock or demise is prevented.Methods: We report a patient with a bilobed placenta and perinatal hemorrhage caused by vasa previa that was not detected with antepartum ultrasound. A review of the literature published between January 1965 and August 2002 was conducted using a MEDLINE-assisted search using the key words "vasa previa," "bilobed placenta," and "succenturiate.

“…1 The membranous fetal vessels can either lead from the placenta to a velamentous cord insertion (type 1) or connect the main bulk of the placenta to a succenturiate lobe (type 2). 2 The localization of the membranous fetal vessels can be classified as overlying (located directly over the internal os) or low-lying (located apart from the internal os but in front of the fetal presenting part).…”

“…Therefore, while safe vaginal delivery is clearly out of the question in the presence of overlying VP, it remains to be determined whether all cases with low-lying VP require elective cesarean section. 2 Here, we describe our experience in two cases of prenatally diagnosed low-lying VP where vaginal deliveries were attempted with extreme caution. We also review past case reports that described details of the clinical course leading to the VP rupture to find out certain preventive measures against VP rupture during vaginal delivery.…”

We herein describe our experiences in vaginal deliveries for women with prenatally diagnosed vasa previa (VP).Case 1: A 29-year-old uniparous woman was referred to us at 34 +4 gestational weeks. Trans vaginal ultrasonography (TV-USG) showed a membranous fetal vein located 1.1cm apart from the internal cervical os. At 34 +6 gestational weeks, spontaneous rupture of membranes (ROM) occurred, and labor was naturally initiated at 36 +1 gestational weeks. The progression of labor was favorable and a non-anemic male baby weighing 2290g was vaginally delivered 9.5hours after the onset of labor.Case 2: A 32-year-old primiparous woman was referred at 39 +2 gestational weeks. TV-USG showed a pair of membranous fetal vein and artery located 1.0cm apart from the internal cervical os. At 40 +4 gestational weeks, spontaneous ROM occurred and labor was naturally initiated 2hours later. After labor augmentation with intravenous prostaglandin F2α, a non-anemic female baby weighing 2715g was vaginally delivered 22hours after the onset of labor.These experiences and a review of past case reports suggest that an early minimallytraumatic amniotomy, avoidance of excessive cervical manipulation, and the shortening of the expulsive stage could contribute to the prevention of VP rupture.
