Discrepancia de longitud de los miembros inferiores tras canalización arterial en niños / Limb lengh shortening after arterial cannulation in infancy

Objetivos. Conocer la posible asociación entre la realización de canalizaciones arteriales con el desarrollo de discrepancias de longitud en los miembros inferiores y de alteraciones del crecimiento del fémur proximal en la infancia. Material y métodos. Se realiza un estudio retrospectivo de 300 niños que precisaron una canalización arterial y/o un cateterismo cardíaco durante la infancia en relación con la existencia de patología cardiovascular congénita. Durante su seguimiento en la consulta de cardiología pediátrica, a 7 de ellos se les detectó una discrepancia de longitud de los miembros inferiores (MM II) por lo que fueron remitidos a nuestras consultas externas para estudio. Resultados. Los 7 pacientes fueron valorados en nuestra consulta con una media de 10 años de edad. La media de discrepancia de longitud fue de 2,7 cm, más frecuente en el lado derecho a expensas de fémur y tibia. Tres de los pacientes presentaron una deformidad de la extremidad proximal del fémur: 2 casos de caput valgum y uno de apofisiodesis aislada bilateral de trocánter mayor. Todos los niños fueron tratados inicialmente con un alza en el miembro más corto. Uno de ellos precisó un alargamiento tibial y 2 de ellos están a la espera de alargamiento para la compensación de la discrepancia. Conclusión. Es recomendable el seguimiento clínico y radiológico de los pacientes a los que se les haya realizado un cateterismo en su primera infancia por la relación que existe entre estas técnicas y el riesgo de desarrollar una discrepancia de longitud en el miembro inferior (AU)

Objectives. The aim of this study was to assess the relationship between arterial cannulations and the development of limb length discrepancies in childhood or impaired growth of the proximal femur. Material and Methods. A retrospective study was conducted on 300 children who required arterial cannulation and/or cardiac catheterisation during childhood in relation to congenital heart diseases. Seven of these patients were referred from the Paediatric Cardiology clinic due to a limb length discrepancy and/or proximal femoral deformities. Results. Seven children, with a mean age of 10 years, were referred to our clinic. The mean length discrepancy was 2.7 cm, and was more frequent on the right side. Three of the patients presented with proximal femoral deformities: two cases of caput valgum and one of bilateral physeal arrest of the greater trochanter. All children were initially treated with a shoe lift in the shortest limb. One of them required a tibial lengthening and two others are awaiting a similar procedure. Conclusion. We recommend clinical and radiological follow-up of patients who have undergone catheterisation during their infancy due to the relationship between these techniques and the risk of developing a limb length discrepancy (AU)
