Breech Presentation: Vaginal Versus Cesarean Delivery, Which Intervention Leads to the Best Outcomes?

INTRODUCTION: The best route of delivery for the term breech fetus is still controversial. We aim to compare maternal and neonatal outcomes between vaginal and cesarean term breech deliveries. MATERIAL AND METHODS: Multicentric retrospective cohort study of singleton term breech fetuses delivered vaginally or by elective cesarean section from January 2012 - October 2014. Primary outcomes were maternal and neonatal morbidity or mortality. RESULTS: Sixty five breech fetuses delivered vaginally were compared to 1262 delivered by elective cesarean. Nulliparous women were more common in the elective cesarean group (69.3% vs 24.6%; p < 0.0001). Gestational age at birth was significantly lower in the vaginal delivery group (38 ± 1 weeks vs 39 ± 0.8 weeks; p = 0.0029) as was birth weight (2928 ± 48.4 g vs 3168 ± 11.3 g; p < 0.0001). Apgar scores below seven on the first and fifth minutes were more likely in the vaginal delivery group (1st minute: 18.5% vs 5.9%; p = 0.0006; OR 3.6 [1.9 - 7.0]; 5th minute: 3.1% vs 0.2%; p = 0.0133; OR 20.0 [2.8 - 144.4]), as was fetal trauma (3.1% vs 0.3%: p = 0.031; OR 9.9 [1.8-55.6]). Neither group had cases of fetal acidemia. Admission to the Neonatal Intensive Care Unit, maternal postpartum hemorrhage and the incidence of other obstetric complications were similar between groups. DISCUSSION: Although vaginal breech delivery was associated with lower Apgar scores and higher incidence of fetal trauma, overall rates of such events were low. Admission to the neonatal intensive care unit and maternal outcomes were similar. CONCLUSION: Both delivery routes seem equally valid, neither posing high maternal or neonatal complications' incidence.

Introdução: A melhor via de parto do feto pélvico de termo ainda é controversa. Pretendemos comparar desfechos maternos e neonatais entre partos vaginais e cesarianas de fetos pélvicos de termo. Material e Métodos: Estudo de coorte, multicêntrico e retrospetivo, incluindo gestações de feto único de termo, em apresentação pélvica, que terminaram em parto vaginal ou cesariana eletiva entre janeiro de 2012 e outubro de 2014. Os desfechos primários foram a morbilidade e mortalidade maternas e neonatais. Resultados: Sessenta e cinco partos vaginais foram comparados com 1262 cesarianas eletivas. As nulíparas foram mais frequentes no grupo das cesarianas (69,3% vs 24,6%; p < 0,0001). A idade gestacional foi inferior nos partos vaginais (38 ± 1 semanas vs 39 ± 0,8 semanas; p = 0,0029), verificando-se o mesmo para o peso ao nascer (2928 ± 48,4 g vs 3168 ± 11,3 g; p < 0,0001). Índices de Apgar < 7 foram mais frequentes nos partos vaginais (1º minuto: 18,5% vs 5,9%; p = 0,0006; OR 3,6 [1,9 - 7,0]; 5º minuto: 3,1% vs 0,2%; p = 0,0133; OR 20,0 [2,8 - 144,4]). Verificou-se também uma maior incidência de traumatismo fetal neste grupo (3,1% vs 0,3%; p = 0,031; OR 9,9 [1,8 - 55,6]). Nenhum grupo teve casos de acidemia fetal. As taxas de internamento na unidade de cuidados intensivos neonatais, de hemorragia materna pós-parto ou de outras complicações obstétricas foram idênticas. Discussão: O parto vaginal associou-se a índices de Apgar inferiores e a uma maior incidência de traumatismo fetal, com taxas globalmente baixas. Não se verificaram diferenças nas taxas de internamento neonatal nem nos desfechos maternos. Conclusão: Ambas as vias de parto parecem adequadas, nenhuma condicionando incidências elevadas de complicações maternas ou neonatais.

Levels of agreement between clinical examination and transabdominal ultrasound evaluation of fetal head position in the second stage of labor.

AIM: To compare transvaginal digital examination performed by residents and attending physicians to transabdominal suprapubic ultrasound in the evaluation of fetal head position in the second stage of labor. METHODS: A prospective study was conducted at a tertiary center and included pregnant women at term, with normal singleton cephalic presentation fetuses. All patients had ruptured membranes and were evaluated during the second stage of labor. Fetal head position was assessed consecutively by two clinicians (one resident and one attending physician). Afterwards, transabdominal suprapubic ultrasound was performed by another observer. Examiners were blinded to each other's findings. Cohen's kappa test was used to assess the degree of agreement between the evaluation methods. RESULTS: One-hundred sixty-one women were included. Transvaginal examination was consistent with the ultrasound in 45.0% of cases (95% CI: 37-53%) when the examination was performed by residents (k = 0.349) and in 67% (95% CI: 60-74%) if the attending physician carried out the evaluation (k = 0.604). When considering only the anterior positions, the Cohen's kappa test was 0.426 and 0.709, respectively. CONCLUSION: Transabdominal suprapubic ultrasound improved the accuracy of the evaluation of fetal head position, namely when transvaginal digital examination was performed by residents. This may be important especially when instrumental deliveries are considered.

Fetal bronchopulmonary malformations.

INTRODUCTION: Fetal body tumors are rare, but the ability to diagnose them has improved over recent years. Most masses discovered in the chest results from fetal bronchopulmonary malformations, such as congenital cystic adenomatoid malformation and bronchopulmonary sequestration. Congenital cystic adenomatoid malformation and bronchopulmonary sequestration have a reported incidence of 50% and 33% of all prenatally diagnosed lung lesions, respectively. MATERIAL AND METHODS: Retrospective analysis of the congenital cystic adenomatoid malformation and bronchopulmonary sequestration cases diagnosed or surveilled at our department, between January 2003 and March 2013. Prenatal examination, evolution, management and patient outcome were analyzed. RESULTS: A total of 918 fetal malformations were diagnosed at our hospital, 17 of them representing fetal bronchopulmonary malformations. The majority were diagnosed during the second trimester and stabilized or regressed during the third trimester of pregnancy. The pregnancies and deliveries had no other relevant findings or complications, except in three cases. Nine children required surgery. All of the children are healthy and have a normal development, with regular surveillance by the pediatricians. DISCUSSION: The majority of these fetal lung masses are isolated findings that partially regress during intrauterine life. With adequate postnatal surveillance and eventual surgery the prognosis is good.

Effect of vaginal intercourse on spontaneous labor at term: a randomized controlled trial.

OBJECTIVE: This study aimed at evaluating the effect of vaginal intercourse on spontaneous labor onset at term. METHODS: In a randomized controlled trial, patients with singleton, cephalic, term, and low-risk pregnancy were assigned to either vaginal intercourse at least twice a week or abstinence. The following data were assessed: demographics, parity, vaginal coitus frequency before and during pregnancy, Bishop score at 38th weeks, gestational age at delivery, mode of delivery, and days between recruitment and delivery. The primary outcome was spontaneous labor onset. RESULTS: Of the 123 patient analyzed, 63 were assigned to study group and 60 to control group. Mean interval between study recruitment and delivery was higher in sexually active women (15.05 days ± 0.8 compared with 14.17 days ± 0.8, p = 0.45) as well as the rate of cesarean delivery (14.3 % compared with 10 %, p = 0.58), but the differences were not statistically significant. The rate of spontaneous labor was similar in both groups (84.1 % in vaginal coitus group; 75 % in control group, p = 0.26). CONCLUSION: Our results showed that vaginal intercourse does not hasten spontaneous labor onset at term.

Ureterocele: antenatal diagnosis and management.

Ureteroceles are cystic dilations of the intravesical submucosal ureter. Most cases are associated with complete ureteral and renal duplication, and association with ureterohydronephrosis is frequent. The authors describe the 4 cases of fetal ureterocele diagnosed from March 2008 to March 2012. Mean gestational age at diagnosis was 23 weeks (16-34 weeks). One of 4 cases progressed to severe hydronephrosis with megacystis and was referred to a Fetal Medicine Center for fetoscopy and laser ureterocelotomy. The remaining 3 cases did not need fetal therapy. Mean gestational age at delivery was 37 weeks. One case abandoned follow-up; 2 children were submitted to cystoscopic ureterocele incision and the child submitted to fetal therapy needed heminephrectomy due to recurrent urinary tract infections. In those 3 cases renal function was preserved. When a fetal ureterocele is diagnosed, close sonographic surveillance should be offered to monitor the possible urinary tract obstruction and assess the need for prenatal intervention. Fetal diagnosis is important to program the timing of delivery and postnatal care.

Limb constriction secondary to pseudoamniotic band syndrome after selective fetoscopic laser surgery: report of a case with a favorable outcome.

Pseudoamniotic band syndrome (PABS) is an iatrogenic complication that causes entanglement of fetal parts in a constrictive sheet of detached or ruptured amniotic membrane after an invasive procedure, namely amniocentesis, amnioreduction or septostomy in twins. The incidence and risk factors for PABS after fetoscopy-guided laser have not been documented [Winer et al.: Am J Obstet Gynecol 2008;198:393.e1-393.e5]. We report a case of monochorionic biamniotic twin pregnancy submitted to selective fetoscopic laser photocoagulation for twin-to-twin transfusion syndrome at 16 weeks of gestation. The procedure was complicated by the death of one of the fetuses at 24 weeks of gestation. Moreover, the surviving twin was diagnosed postnatally with pseudoamniotic band syndrome, presenting with affected limbs. The newborn was submitted to surgical correction of these lesions with a successful outcome and was discharged on day 15.

Prenatal diagnosis of persistent urogenital sinus with duplicated hydrometrocolpos and ascites--a case report.

We report a successful case of persistent urogenital sinus associated with a duplicated nonsyndromic form of hydrometrocolpos and ascites diagnosed prenatally. Though urogenital malformations are extremely rare and variable in presentation, the conjugation of those anomalies in a newborn is reported here for the first time. Prenatal ultrasound diagnosis was suspected at 25 weeks' gestation and MRI imaging supported the diagnosis. Periodic ultrasound surveillance was conducted until birth at 35 weeks' gestation by cesarean section. The presumptive diagnosis was confirmed after birth. One month later, the newborn underwent reconstructive surgical intervention with good outcome.

Prenatal diagnosis of a congenital postaxial longitudinal limb defect: a case report.

Introduction. Although congenital longitudinal fibular deficiency is one of the most common long bone deficiencies, there are few published cases of its prenatal diagnosis. Case report. A right longitudinal deficiency of the fibula associated with tibial shortening, foot equinovalgus, and absence of the fourth and fifth foot rays diagnosed at 22 weeks gestation is described. Sequential ultrasonographic surveillance was performed without obstetric complications. The anomaly was confirmed after birth, and conservative orthopaedic management was decided. Conclusion. Though rarely seen, postaxial longitudinal limb defect may be detected by ultrasound. The correct approach can only be decided after birth, when the functional impact of the anomaly can be fully evaluated.

Sexuality during pregnancy.

INTRODUCTION: Sexuality is an important part of health and well-being. Sexual behavior modifies as pregnancy progresses, influenced by biological, psychological, and social factors. AIM: To evaluate changes in sexual perceptions and activities during pregnancy and to determine sexual dysfunctions in that period. MAIN OUTCOME MEASURES: Sexual perceptions (desire from the partner, feelings of attractiveness, and fear of sexual intercourse), sexual activities during pregnancy (sexual intercourse frequency, the most frequent sexual intercourse trimester, sexual activity during the birth week, type(s) of sexual intercourse, changes in sexual satisfaction and desire compared with the pre-pregnancy period, and changes in sexual intercourse frequency during each trimester compared with the pre-pregnancy period), and sexual dysfunctions. METHODS: Puerperal women were asked to anonymously complete a self-administered and structured questionnaire at the day of discharge from hospital. RESULTS: One hundred and eighty-eight women, aged between 17 years and 40 years with a mean age of 28.9 years, were analyzed. The first trimester was considered the most frequent period of sexual intercourse (44.7%), followed by the second trimester (35.6%). Fifty-five percent reported a decrease of sexual activity during the third trimester. Fear of sexual intercourse was referred by 23.4% of the women questioned. Sexual satisfaction was unchanged in 48.4% of the subjects and decreased in 27.7% (P < 0.0001); sexual desire is reported to be unchanged in 38.8% and decreased in 32.5% (P = 0.196) of the population. Vaginal, oral, anal sex, and masturbation were performed by 98.3%, 38.1%, 6.6%, and 20.4% of the women, respectively. CONCLUSIONS: We determined in our study that sexual satisfaction do not change in pregnancy compared with the pre-pregnancy patterns despite a decline of sexual activity during the third trimester. A discussion of expected changes in sexuality should be routinely done by the doctor in order to improve couples' perception of possible sexual modifications induced by pregnancy.

Ultrasonographic diagnosis of fetal ovarian cysts: five cases in five years.

OBJECTIVE: To evaluate the outcome of ultrasonographically diagnosed fetal ovarian cysts within a 5-year period. METHODS: This was a retrospective evaluation of the prenatal and postnatal medical records of the five cases of fetal ovarian cyst diagnosed at our institution from January 2002 to December 2006. RESULTS: The mean gestational age at diagnosis was 31.6 weeks. One of the patients had type I diabetes and another had chronic hypertension and preeclampsia. The mean cyst diameter at diagnosis was 38.3 mm (range 29-60 mm). When diagnosed, four of the cysts were simple and the other was septated. During pregnancy, the septated cyst and two of the simple cysts became hemorrhagic. Postnatally the septated cyst and two of the simple cysts underwent spontaneous remission; the other two cases, corresponding to hemorrhagic cysts, were surgically removed after birth. CONCLUSIONS: The best clinical approach to a fetal ovarian cyst is controversial. In this small series, three of the five cysts regressed spontaneously, including a hemorrhagic one. Once a fetal ovarian cyst is diagnosed, ultrasonographic monitoring should be provided in order to identify complications and define the best therapeutic approach.

Prenatal ultrasonographic diagnosis of abdominal cystic lymphangioma: a case report.

Abdominal lymphangioma is a rare tumor of the lymphatic vessels. A case of an abdominal cystic lymphangioma identified at 22 weeks of gestation is reported. Ultrasonographic monitoring showed a progressive increase of mass size during the gestation. Pregnancy was terminated at 38 weeks and the newborn was submitted to a laparotomy with resection of all cystic structures. At the present time the infant is three years old and is doing well.

Prenatal ultrasonographic diagnosis of vein of Galen aneurysms--report of two cases.

Aneurysms of the vein of Galen (AVG) represent less than 1% of all intracranial arteriovenous malformations. Two cases of prenatal diagnosis made by color Doppler ultrasonography at 32 weeks of gestation are reported. Both cases presented with antenatal mild cardiomegaly and both developed severe cardiac failure in the neonatal period. Embolization was unsuccessful and both infants died. These cases highlight the need for a careful evaluation of the time and mode of delivery; embolization must be performed after a fully informed decision.
