Fetoscopy for meningomyelocele repair: past, present and future

Abstract: Meningomyelocele is a malformation with high prevalence, and one of its main comorbidities is Arnold-Chiari malformation type II. The intrauterine repair of this defect has been studied to reduce the progressive spinal cord damage during gestation. The purpose of the present review was to describe the evolution of fetal surgery for meningomyelocele repair. Searches on PubMed database were conducted including articles published in the last 10 years. Twenty-seven articles were selected, 16 experimental studies a… Show more

“…MMC is associated with a number of other disorders, such as motor deficit and fecal and urinary incontinence, as well as with several malformations of the central nervous system (CNS) resulting from herniation of the posterior fossa components to the medullary canal. This set of malformations of the CNS, known as Arnold-Chiari Type II Malformation (ACMII), can lead to progressive dilation of the cerebral ventricles and consequent need for ventriculoperitoneal shunt (VPS) for the treatment of hydrocephalus (19) . In this study, associated risk indicators were collected in this population, observing that most infants with MMC and ACMII, in the Study Groups 1 and 2 (SG2 and SG1), respectively, remained in neonatal intensive care unit (NICU) longer than five days.…”

“…De acordo com Simões (1988) MACGRATH e SIMON, 1983). O real mecanismo pelo qual se inicia a contração da ferida é ainda controvertido; pode ocorrer nos bordos da ferida (ARAÚJO, 1997;BEVILACQUA et al, 1981), ou na sua parte mais profunda, ou em ambos os locais (BEVILACQUA et al, 1981;KITCHEN e YOUNG, 1998). No curto prazo, o fechamento de uma ferida pela contração de suas margens é considerado insuficiente, pois resta quase sempre uma área central cujo fechamento é por epitelização, de modo que a cicatrização se completa como resultado de uma combinação dos processos de contração e epitelização (MACGRATH e SIMON, 1983).…”

“…A reação vascular local é caracterizada, inicialmente, por uma vasoconstrição, que previne a perda sanguínea ou de líquidos corporais, durando de alguns segundos a poucos minutos (GONÇALVES e PARIZOTTO, 1998;KITCHEN e YOUNG, 1998;SIMÕES, 1988). Segue-se, então, uma vasodilatação, com aumento da permeabilidade capilar, causada por agentes como a bradicinina e a histamina, levando a uma separação reversível entre as células endoteliais que permite a saída dos fluídos e macromoléculas para o interstício, juntamente com leucócitos, responsáveis pela fagocitose e, uma pequena parte, pela resposta imune mediada por células (BEVILACQUA et al, 1981).…”
