Traumatic Subdural Hygromas: Proposed Pathogenesis Based Classification

Abstract

SSEff detected in the first 24 hours posttrauma in our series evolved into TSHy suggesting that this is an early lesion; all THSy were divided in three groups according to the pathophysiologic mechanism. These three groups probably represent a continuum of CSF absorption impairment. Group Ia represents what most authors consider a simple hygroma, with no impairment on CSF absorption. Group Ib represent the external hydrocephalus form with various degrees of CSF imbalance, and group II were the cases presenting marked mass effect.

Coleções subdurais crônicas não infecciosas: Aspectos epidemiológicos e resultados em 581 pacientes consecutivos submetidos a tratamento cirúrgico

“…O HSD é uma coleção semelhante ao líquor: apresentando conteúdo líquido claro, xantocrômico ou levemente hemorrágico. O higroma tem pressão oncótica mais baixa que a do sangue, e menor quantidade de eritrócitos, leucócitos, concentração total de proteínas, albumina e imunoglobulina G que o plasma, porém maior que o liquor (11) . Sua formação geralmente ocorre após traumatismos crânioencefálicos (TCE).…”

“…Tende a diminuir sem nenhuma intervenção, mas pode não reabsorver espontaneamente e até aumentar, tornando-se um processo expansivo que leva a compressão cerebral, necessitando de intervenção cirúrgica. O quadro clínico do higroma geralmente é inespecífico, com distúrbios da consciência sendo mais frequentemente relatados (11)(12) . Neste estudo, os higromas predominaram no gênero masculino (46,84%) e a mediana de idade foi de 55 anos, predominando em menores de 60 anos, semelhante ao observado em publicação realizada por Zanini et al, 2008 em nosso meio (11) .…”

Subdural Hygromas in Abusive Head Trauma: Pathogenesis, Diagnosis, and Forensic Implications

“…Children were even excluded in a recent radiologic SDHy study because their pathogenetic aspects were considered a priori as different from adults. 61 Hereafter, the 2 current basic concepts of SDHy formation with their different medicolegal implications, as well as important alternative explanations, are presented.…”
