Acta Neurochirurgica Aims and scope Submit manuscript

Summary

A method is described for the evaluation of the patency of ventriculoatrial shunts. It is based on local cooling of the shunt and recording of the transported cold at a site downstream, by means of a thermosensitive device connected to a Wheatstone-bridge and a recorder.

Zusammenfassung

Beschreibung einer Methode zur Prüfung der Durchgängigkeit von ventrikulo-atrialen Shunt-Systemen.

Das Prinzip der Methode besteht in einer örtlichen Kühlung des Shunts und Registrierung der Kälteweiterleitung mit dem Flüssigkeitsstrom mit Hilfe von Thermofühlern unter Verwendung einer Wheatstone-Brücke und eines Registriergerätes.

Résumé

Une méthode est décrite pour l'évaluation du fonctionnement des shunts ventriculo-atriaux. Elle est basée sur le refroidissement local du shunt et l'enregistrement du transport du froid par le courant vers l'aval au moyen d'un appareillage thermosensible connecté à un pont de Wheatstone et à un enregistreur.

Riassunto

Gli AA. descrivono un metodo qer la valutazione della pervietà della derivazione ventricolo-atriale basato sul raffreddamento locale della derivazione e la registrazione del freddo transportato dal flusso liquorale discendente mediante un'apparecchiatura termosensitiva collegata con un ponte di Wheatstone ed un registratore.

Resumen

Se describe un método para la valoración del funcionamiento de los shunts ventrículo-atriales. Está basado en el enfriamiento local del shunt y el registre de la transmisión del frio por el flujo sangúíneo hacia abajo, por medio de un aparato termosensible conectado a un puente de Wheatstone y a un aparato de registro.
