Abstract
Objective

It is difficult to demonstrate the success of the procedure in patients with third ventriculostomy. We evaluated that optic nerve sheath diameter (ONSD) measurement, which can reflect intracranial pressure, may be a criterion for decision of endoscopic third ventriculostomy (ETV) success.

Methods

28 adult patients suffering long overt standing ventriculomegaly (LOVA) who performed ETV were included in this retrospective study. The patients were divided into two groups as successful (group A) and failed ETV group (group B) according to their postoperative evaluation. ONSD was measured on pre- and post-operative computed tomography (CT) and Evan's index (EI), diameter of third ventricule (V3), the patency of ETV stoma and periventricular edema were evaluated by magnetic resonance imaging (MRI).

Results

The mean ONSD was measured as 6.39±0.92mm for the right eye, 6.50±0.91mm for the left eye on preoperative CT. The mean ONSD by CT (after surgery) was 4.89±0.87mm for the right eye, 5.02±0.1mm for the left eye (p<0.05). Postoperative group A and group B were compared according to ONSD measurement; mean ONSD in group A was 4.52±0.69mm for the right and 4.59±0.9mm for the left, mean ONSD in group B was 5.82±0.51mm for the right and 6.1±0.32mm for the left (p<0.05). The best ONSD value for detecting failed ETV was 5.40mm (sensitivity 90%, specifity 75%, AUROC 0.938) for right and 5.91mm (sensitivity 90%, specifity 75%, AUROC 0.950) for left. EE was measured as 0.39±0.12mm on preoperative MRI and 0.39±0.12mm on postoperative MRI (p=0.3). V3 was measured as 14.7±2.47mm on preoperative MRI and 10.47±1.99mm on postoperative MRI (p<0.05).

Conclusion

The statistical values obtained from study show that the ONSD measurement can help in the postoperative evaluation of patients, who had a ETV surgery.

Resumen
Objetivo

Es difícil demostrar el éxito del procedimiento en pacientes con ventriculostomía premamilar. Evaluamos que la medición del diámetro de la vaina del nervio óptico (ONSD), que puede reflejar la presión intracraneal, puede ser un criterio para la decisión del éxito de la ventriculostomía endoscópica (VE).

Métodos

En este estudio retrospectivo se incluyeron 28 pacientes adultos que sufrían ventriculomegalia marcada de larga evolución (LOVA) que realizaron VE. Los pacientes se dividieron en dos grupos, según su evaluación postoperatoria: el grupo de ETV exitosa y el grupo fallido. La ONSD se midió en tomografía computarizada (TC) pre- y postoperatoria, y el índice de Evan (IE), el diámetro del tercer ventrículo (V3), la permeabilidad del estoma VE y el edema periventricular se evaluaron mediante imágenes de resonancia magnética (IRM).

Resultados

La ONSD media se midió como 6,39±0,92mm para el ojo derecho, 6,50±0,91mm para el ojo izquierdo en la TC preoperatoria. La ONSD media por TC (después de la cirugía) fue de 4,89±0,87mm para el ojo derecho, 5,02±0,1mm para el ojo izquierdo (p<0,05). El grupo postoperatorio A y el grupo B se compararon según la medición ONSD. La media de ONSD en el grupo A fue de 4,52±0,69mm para el derecho y de 4,59±0,9mm para el izquierdo; la media de ONSD en el grupo B fue de 5,82±0,51mm para el derecho y 6,1±0,32mm para el izquierdo (p<0,05). El mejor valor de ONSD para detectar VE fallida fue de 5,40mm (sensibilidad 90%, especificidad 75%, AUROC 0,938) para el derecho y 5,91mm (sensibilidad 90%, especificidad 75%, AUROC 0,950) para el izquierdo. IE se midió como 0,39±0,12mm en la IRM preoperatoria y 0,39±0,12mm en la IRM postoperatoria (p=0,3). V3 se midió como 14,7±2,47mm en la IRM preoperatoria y 10,47±1,99mm en la RM postoperatoria (p<0,05).

Conclusión

Los valores estadísticos obtenidos del estudio muestran que la medición de ONSD puede ayudar en la evaluación postoperatoria de los pacientes que se sometieron a una cirugía de ETV.
