Arteriovenous malformations are the most common vascular congenital malformation of the brain. The vein of Galen arteriovenous malformation (VGAM) consists of end-to-end aneurysms in which the artery and vein connect without intervening capillaries. Cardiomegaly with congestive heart failure and increased intracranial pressure with hydrocephaly are the most common features in the neonate. In this case report, both features are present in utero. Prenatal morbidity and mortality are high due to cardiac failure. The authors present a case of spontaneous delivery at 35 weeks with one twin affected with vein of Galen aneurysm.

Background: Preterm infants born at <32 weeks gestational age (GA) have increased morbidity if they are born outside tertiary centres (outborn). Stabilization and resuscitation after birth consistent with the neonatal Golden Hour practices (NGHP) are required to optimize outcomes., Objectives: To evaluate physiological outcomes of hypothermia and hypoglycaemia, and compliance with NGHP by neonatal transport team (NTT) compared with referral hospital team (RHT) during the stabilization of infants born at <32 weeks GA., Methods: A retrospective case-control study of infants born at <32 weeks GA during 2016-2019 at non-tertiary perinatal centres where the NTT attended the delivery (cases) were matched to infants where the RHT team attended the delivery (controls)., Results: During the 4-year period, NTT team received 437 requests to attend deliveries at <32 weeks GA and attended 76 (17%) prior to delivery. These cases were matched 1:1 with controls composed of deliveries attended by the RHT. The rate of hypothermia was 15% versus 29% in the NTT and RHT groups, respectively (P = 0.01). The rate of hypoglycaemia (<2.2 mmol/L) was 5% versus 12% in the NTT and RHT groups, respectively (P = 0.64). For compliance with the NGHP, use of fluid boluses was 8% versus 33%, use of thermoregulation practices, that is, plastic bag, was 76% versus 21%, and establishment of intravenous access was 20 min versus 47 min, in the NTT and RHT groups, respectively., Conclusions: High-risk preterm deliveries attended by the NTT compared with the RHT had increased compliance and earlier implementation of the NGHP elements, associated with improved physiological stability and lower hypothermia rates. Outreach education for RHT should ensure that these key elements are included during the training in the stabilization of high-risk preterm deliveries., Competing Interests: All authors reported that there are no conflicts of interest.

Objective: To evaluate prospectively whether saline-infusion sonography endometrial sampling will improve diagnosis of benign and malignant endometrial disease compared with blind endometrial biopsy in perimenopausal and postmenopausal women with abnormal uterine bleeding., Methods: After initial assessments and endometrial biopsies, women aged 40 or older with abnormal uterine bleeding were referred for transvaginal ultrasonography. Patients with abnormal endometrial evaluations were offered sonohysterography and invited to enter the saline-infusion sonography endometrial sampling study. Saline-infusion sonography endometrial sampling was performed at the end of sonohysterography using an endometrial sampling curette at the sight of the endometrial abnormality or at a representative site in the endometrial cavity if the cavity was normal. Histopathologic diagnoses of blind endometrial biopsy and saline-infusion sonography endometrial sampling were compared with final outcomes. Kappa values for the two sampling techniques were calculated for diagnostic accuracy., Results: A total of 88 saline-infusion sonography endometrial samples were obtained; final outcomes were attained in 80 cases. When comparing saline-infusion sonography endometrial sampling with final outcomes, saline-infusion sonography endometrial sampling provided a diagnosis 89% of the time (95% confidence interval [CI] 82-95%) compared with endometrial biopsy at 52% (95% CI 42-62%). Forty-five patients with endometrial biopsies had final outcomes. When comparing endometrial biopsy with final outcomes, endometrial biopsy underestimated the incidence of pathology, especially when focal lesions and malignancy were present. This difference was statistically significant (P<.005)., Conclusion: Saline-infusion sonography endometrial sampling is superior to endometrial biopsy in diagnosing endometrial pathology in perimenopausal and postmenopausal women with abnormal uterine bleeding., Level of Evidence: II.
