Abstract
Purpose
To evaluate the feasibility and utility of serial measuring of the optic nerve sheath diameter beyond the hyperacute and acute stage of intracerebral hemorrhage (ICH).
Methods
Four patients with extensive ICH in the left basal ganglia were followed using ultrasound (US) and cerebral CT scans.
Results
Optic nerve sheath diameter values assessed beyond the acute stage of ICH showed a high correlation (ρ = 0.84, p = 0.0022) with midline shift of the third ventricle seen on CT scans.
Conclusions
Optic nerve sonography can be useful to evaluate patients with extensive ICH beyond the acute stage and help monitoring clinical evolution in these patients, when ICP monitoring is not feasible.
Riassunto
Obiettivi
Valutare l′utilità clinica della misurazione seriale del diametro del nervo ottico e dei suoi rivestimenti dopo la fase acuta dell′emorragia cerebrale.
Metodi
Quattro pazienti con emorragia cerebrale sono stati sottoposti ad ecografia del nervo ottico e tomografia assiale computerizzata (TAC) del cranio.
Risultati
I valori del diametro del nervo ottico e dei suoi rivestimenti correlavano in maniera marcata con lo shift della linea mediana del terzo ventricolo evidenziato alla TAC cerebrale.
Conclusioni
La sonografia del nervo ottico con la misurazione del diametro del nervo ottico e dei suoi rivestimenti potrebbe costituire un utile strumento nel valutare l’evoluzione clinica dei pazienti con estesa emorragia intracranica, qualora la misurazione della pressione intracranica non fosse eseguibile.
