Background: Persistent right umbilical vein (PRUV) is usually an isolated findingbut it may be accompanied by other fetal malformations.Aims: We aimed to determine the incidence of prenatally diagnosed PRUV in a referral population, assess the neonatal outcome and discuss the findings together with those from previous publications. Materials and methods:A total of 2360 women with low-risk singleton pregnancies were examined in the second and third trimesters. A transabdominal convex volume transducer was used. B-mode was applied in each patient. Scanning of the venous system included imaging of the target vessels with two-dimensional colour Doppler mapping. The diagnosis of PRUV was made in a transverse section of the fetal abdomen. Three-dimensional ultrasounds were performed as necessary, when anomalous cases were encountered. Results:The incidence of PRUV in our population was 12/2360 = 0.5%, and it was higher than in other retrospective studies. In 75% (n = 9), PRUV was an isolated finding where delivery was uneventful and the postnatal outcome was favourable. In two cases PRUV was accompanied by omphalocele, and in one case by tetralogy of Fallot and single umbilical artery. Conclusions:PRUV is an uncommon prenatal finding. Screening for this anomaly can be easily performed in all pregnant patients. A diagnosis of PRUV should be followed by a thorough fetal morphology scan in order to exclude any other malformations, especially those of the cardiovascular system.

Introduction Following laparoscopic myomectomy, uterine rupture during pregnancy or delivery in the area of the scar is a very rare but dangerous complication. Individual cases of uterine rupture during pregnancy are described in the literature. Setting University Teaching Hospital. Material Casereport of uterine rupture after delivery in a patient who had previously undergone laparoscopic myomectomy. In the case presented here, the patient conceived 2 months after an 8‐cm subserous myoma with a pedicle had been laparoscopically removed. Intervention No symptoms suggesting uterine rupture were observed during the pregnancy. Spontaneous vaginal delivery was under way, but in the third stage of delivery the condition of the patient deteriorated and symptoms of oligaemic shock developed. A laparotomy was performed, which showed the presence of blood in the peritoneal cavity and ruptured uterine muscle in the scarred area about 5 cm. Conclusions In patients who have previously undergone a laparoscopic myomectomy, there is some risk of uterine muscle rupture at delivery. This is also the case where no suturing of the uterine muscle had been required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
