RESUMO
INTRODUCTION: Open spina bifida (OSB) is the most common congenital anomaly of the central nervous system. It is associated with severe neurodevelopmental delay, motor impairment, hydrocephalus, and bowel and bladder dysfunction. In selected cases, intrauterine spina bifida repair has been shown to improve neonatal outcomes. Rarely, the spine can have a double defect compromising two different segments and there is a lack of evidence on the feasibility and benefits of intrauterine repair in these cases. CASE PRESENTATION: We present a case with both cervicothoracic and lumbosacral myelomeningocele, Arnold-Chiari malformation type II and bilateral ventriculomegaly, that was treated successfully at 25 weeks with open micro-neurosurgery. Double myelomeningocele was successfully treated through a single 2-cm micro-hysterotomy, by performing external versions to sequentially expose and repair both defects. Weekly postoperative follow-up showed no progression of ventriculomegaly or complications attributable to the procedure. Preterm rupture of membranes prompted a conventional cesarean delivery at 32 weeks of gestation. Neurodevelopmental outcome at 20 months was within normal ranges, having achieved ambulation without orthopedic support and with no need for ventriculoperitoneal shunting. CONCLUSION: This report demonstrates for the first time the feasibility of double OSB repair through a single 2-cm micro-hysterotomy, suggesting that selected isolated cases of double myelomeningocele could be candidates for fetal intervention. Further prospective studies should be carried out to assess the potential benefit of double OSB intrauterine open repair.

OBJECTIVE: To evaluate maternal and perinatal outcomes of late open fetal repair for open spina bifida (OSB) between 26+0 -27+6 weeks. METHODS: A cohort of fetuses with OSB who underwent open surgery in two fetal surgery centers (Argentina and Mexico). Two groups were defined based on the gestational age (GA) at intervention: Management of Myelomeningocele Study (MOMS) time window group: GA 19+0 -25+6 , and late intervention group: GA 26+0 -27+6 . RESULTS: Intrauterine OSB repair was successfully performed in 140 cases, either before (n = 57) or after (n = 83) 26 weeks, at on average 25+0 (22+6 -25+6 ) and 26+5 (26+0 -27+6 ) weeks + days, respectively. There were no significant differences in the rate of premature rupture of membranes, chorioamnionitis, oligohydramnios, preterm delivery, perinatal death and maternal complications. The late intervention group showed a significantly lower surgical times (112.6 vs. 124.2 min, p = 0.01), lower interval between fetal surgery and delivery (7.9 vs. 9.2 weeks, p < 0.01) and similar rate of hydrocephalus requiring treatment (30.6% vs. 23.3%, p = 0.44) than the MOMS time window group. CONCLUSION: Late fetal surgery for OSB repair between 26+0 -27+6 weeks is feasible and was associated with similar outcomes than that performed before 26 weeks. These findings may allow an extension of the proposed time window for cases with late diagnosis or referral.

INTRODUCTION: Thromboelastometry evaluates viscoelastic changes in the coagulation process. It offers a graphic representation of the formation of the coagulum, its stability and the presence of lysis. OBJECTIVE: This first case of transfusion management guided by thromboelastography in Mexico and we conducted a review of the literature. METHOD: A metasearch search was performed (PubMed, Scielo, Medigraphic) with the words thromboelastometry, coagulopathy, transfusion medicine and the most influential works were included. CONCLUSIONS: The rotational thromboelastometry is a diagnostic tool that graphs the functionality of the clot, for a directed and individualized management of the coagulopathy associated with bleeding.
INTRODUCCIÓN: La tromboelastometría evalúa los cambios viscoelásticos en el proceso de coagulación. Ofrece una representación gráfica de la formación del coágulo, su estabilidad y la presencia de lisis. OBJETIVO: Se notifica el primer caso de manejo transfusional guiado por tromboelastografía en México con revisión de la bibliografía. MÉTODO: Se realizó una búsqueda en metabuscadores (PubMed, Scielo, Medigraphic) con las palabras tromboelastometría, coagulopatía y medicina transfusional y se incluyeron los trabajos más influyentes. CONCLUSIONES: La tromboelastometría rotacional es una herramienta diagnóstica que grafica la funcionalidad del coágulo para un manejo dirigido e individualizado de la coagulopatía relacionada con hemorragia.
