Abstract:Uma série de 95 crianças hidrocefálicas foram submetidas à derivação ventriculoperitoneal (DVP) com válvula no período de dezembro de 1965 a novembro de 1969. Os resultados obtidos são analisados e comparados com os obtidos mediante derivação ventriculoatrial (DVA). Das crianças operadas, 54 estão vivas e com a hidrocefalia compensada, 9 faleceram, não sendo possível estabelecer as condições atuais das 32 restantes. Com a derivação para o peritônio foram evitadas as severas complicações vasculares e cardiopulm… Show more

Em nossa observação 42,3% das 52 DVP realizadas em 45 crianças foram revisadas uma ou mais vezes ocasionando um índice de 1,02 revisões por paciente, que coincide com a observação de Faulhauer & Schmitz 15 e é inferior ao observado por Scott e col. 3,0 (1,3 revisões por paciente) e por Facure 14 (1,8 revisões por paciente).

The authors analized the complications of fifty seven children with hydrocephalus due to congenital malformation (42.1%), meningitis (36.8%) and tumor (21.1%), that were submitted to surgical treatment for hydrocephalus, from 1970 to 1980. External ventricular drainage and insertion of ventriculostomy reservoir were used to control the expanding hydrocephalus in children with meningitis. Complications weren't observed in the first procedure. Cutaneous abscess, brain abscess, cerebrospinal fluid leakage, wound dehiscence, malposition of the reservoir and local tumor were observed in the use of the ventriculostomy reservoir and these complications caused a revision rate of 0.47 revisions per patient. Hypothalamic ventriculostomy with catheter showed complications (catheter obstruction and meningitis) that caused a revision rate of 0.57 revisions per patient. Ventriculoatrial shunting procedure showed several complications (malposition of the distal catheter, malfunction of the valvular system without obstruction and infection and thrombosis of the superior vena cava), that caused a revision rate of 0.57 revisions per patient. Ventriculo-peritoneal shunting procedure showed infections in 30.8%, malfunction of the valvular system in 32.2% cerebrospinal fluid leakage in 17.3%, malposition of catheter in 13.5%, catheter disconnection in 9.6%, transient abdominal distension in two cases and overdrainage phenomena, ascites and abdominal pseudocyst in one case.

Apresentação de 18 pacientes adultos submetidos à derivação ventriculoperitoneal com válvula. Em 17 casos havia hipertensão intracraniana. Em 10 casos, com período de seguimento de 2 a 48 meses, os sistemas estão funcionando bem. Seis doentes faleceram, não sendo possível estabelecer as condições atuais dos 2 restantes. Em 2 pacientes necropsiados, foi verificada permeabilidade da derivação e ausência de aderências e de peritonite. Oclusão da extremidade peritoneal do cateter não ocorreu em caso algum.
A study into the neurosurgical approach to thirty-five patients with increased intracranial pressure due to inflamatory diseases affecting the central nervous system and meninges is reported. The entitites under consideration were found to have similar surgical aspects despite the heterogeneity of etiologic agents. As regards the surgical treatment, two groups of cases were recognized. Group 1 comprises 7 patientes with symptoms of a space-occupying lesion; in these patients craniotomies were performed with good results. Group 2 included the remainder 28 cases with acquired hydrocephalus. In this group differents methods for ventricular drainage were used, but ventriculo-auriculostomy and specially ventriculo-peritoneal shunts proved to give more gratifying results. Chemotherapy was administred when the etiologic agent was disclosed. Corticosteroids were institued to reduce inflammatory reations and cerebral edema. A review of the literature supported the practical classification and surgical techniques employed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
