ABSTRACT

Derivação Ventrículo-Peritoneal (DVP) é um dos procedimentos mais frequentemente realizados para o tratamento dehidrocefalia. Entretanto, mesmo sendo tecnicamente simples e bem conhecido, existem várias complicações graves que podemocorrer, sendo a perfuração intestinal uma delas. Esta complicação é rara, especialmente entre adultos e geralmente ocorredentro do primeiro ano após o procedimento cirúrgico. Esta pode ainda, ser agravada, tanto por infecção, do sistema nervosocentral ou sistêmica, quanto por aumento da pressão intracraniana devido ao mau funcionamento do sistema de drenagem. Oquadro clínico geralmente oligossintomático muitas vezes torna o diagnóstico difícil, sendo necessário o uso de múltiplos examescomplementares. Existem também inúmeras dúvidas quanto à fisiopatologia e fatores predisponentes para esta complicação.Ainda, devido à sua baixa incidência, sendo descrita, em sua maioria, através de relatos de caso ou pequenas séries, não existeconsenso para seu ideal manejo. O tratamento varia desde abordagens menos invasivas, preservando os componentes da DVP,até a retirada completa de todos os componentes e uso de antibióticos de amplo espectro. Relatamos um caso de perfuraçãointestinal e extrusão de cateter de DVP através do ânus em um paciente adulto, tardiamente, discutindo os dados da literaturasobre este assunto.

ABSTRACT

OBJECTIVE: Analyze the changes in the seminiferous epithelium in rats with carbon tetrachloride-induced cirrhosis (CCl4). MATERIALS AND METHODS: Forty-eight male Wistar rats aged 45-50 days, weighing 150-180 grams were used. Twenty-two rats underwent CCl4-induced cirrhosis with CCl4 0.25 mL/Kg weekly intragastrically once a week, during 10 weeks. Additionally, they had a 44 percent food restriction diet (Group 1). The control group was divided in two subgroups: 13 rats had a 44 percent food restriction diet and no CCl4 (Group 2) and 10 rats were not submitted to CCl4 or food restriction (Group 3). After 10 weeks, the rats were sacrificed and liver sections were collected for histological analysis. The testicular analysis was carried out to evaluate the frequency of tubules in stages VIII and XIV. RESULTS: The mean rates of stage VIII in animals with food restriction plus CCl4-induced cirrhosis and food restriction without CCl4 were significantly different from animals without either food restriction or CCl4 (18.1 ± 5.5 percent, 20.5 ± 2.5 percent and 13.4 ± 3.5 percent, respectively, p = 0.002). The mean rate of stage VIII in rats with cirrhosis was not significantly different from rats without cirrhosis (18.1 ± 5.5 percent and 17.4 ± 4.6 percent respectively). The mean frequency of stage XIV in rats with cirrhosis was significantly greater than rats without cirrhosis (4.7 ± 2.3 percent and 6.8 ± 1.9 percent respectively, p = 0.027). CONCLUSION: Animals with CCl4-induced cirrhosis and food restriction have shown alterations in spermatogenic cycle that were not seen in rats without CCl4-induced cirrhosis and food restriction.
