ABSTRACT

Se describe el caso de un varón de 15 años con cuadro clínico caracterizado por dolor y aumento de volumen de la rodilla derecha, fiebre, diaforesis, cefalea, ganglios palpables y pérdida de peso. En la radiografía y RMN de rodilla se encontró acentuada alteración de la epífisis y metáfisis proximal de la tibia y de la metáfisis distal del fémur. La biopsia e inmunohistoquímica fueron compatibles con linfoma no-Hodgkin difuso de células grandes B.


We report a 15-year-old male patient who presented with pain and edema on the right knee, fever, diaphoresis, headache, palpable lymph nodes and weight loss. Marked alteration of the epiphysis and proximal metaphysis of the tibia, and of the distal metaphysis of the femur were observed in the plain x-ray and MRI images. Biopsy and immunohistochemistry findings were compatible with diffuse large B-cell non-Hodgkin lymphoma.

ABSTRACT

Objetivo: Determinar las principales complicaciones postquirúrgicas en pacientes pediátricos con hidrocefalia en el Hospital Nacional Guillermo Almenara Irigoyen. Material y método: Estudio descriptivo, de tipo serie de casos que incluyó las historias clínicas de pacientes post operados por hidrocefalia mediante la derivación ventriculoperitoneal, entre 0 y 14 años al momento de la primera intervención quirúrgica en la institución indicada. Los datos fueron recolectados en una ficha estandarizada. Se aceptó como significancia estadística p<0,05. Resultados: Se encontró complicaciones en 35,5% de los pacientes. De las complicaciones 54% fueron tempranas y 45% tardías. Las causas fueron: disfunción del sistema, infección y hematoma subdural debido a sobredrenaje, 54,5%, 27,3% y 18,2% respectivamente. De los pacientes con complicaciones: 54,5% tenían hidrocefalia adquirida y 45,5% congénita; 72,7% fueron intervenidos de emergencia y 27,3% de manera electiva. Se encontró asociación estadísticamente significativa entre la etiología de la hidrocefalia y las complicaciones registradas χ2 = 5,387 (p = 0,02). Conclusiones: Se encontró una frecuencia de 35,5% de complicaciones post quirúrgicas, siendo la disfunción del sistema la complicación más frecuente en este escenario. Los resultados indican que la hidrocefalia adquirida presenta mayor riesgo de presentar complicaciones postquirúrgicas que la congénita.


Objective: To determine the main surgical complications in pediatric patients with hydrocephalus in Guillermo Almenara Irigoyen National Hospital. Material and method: A descriptive case series reviewed the charts of pediatric patients with hydrocephalus who underwent a ventriculo-peritoneal shunt procedure. These patients were between 0 and 14 years old when they had their first surgery. Data was collected in a standardized chart. Statistical significance was established in p<0.05. Results: Approximately one third of patients (35.5%) developed complications. Fifty- four percent had early complications and 45% developed late complications. Causes for complications were: system malfunction, infection and subdural hematoma caused by overdrainage of VP shunts in 54.5%, 27.3% and 18.2%, respectively. Of all patients who developed complications, 54.5% had acquired and 45.5% had congenital hydrocephalus; 72.7% underwent emergency surgery and 27.3% underwent elective surgery. There was a statistically significant association between the origin of hydrocephalus and the development of complications, χ2 = 5.387 (p = 0.02). Conclusions: The frequency of complications after surgical therapy for hydrocephalus was 35.5%. The main cause was system malfunction. These results show that acquired hydrocephalus has a greater likelihood for developing post surgical complications compared to congenital hydrocephalus.
