Abstract

In the diagnosis of acute vestibular syndrome (AVS) the key part is a quick and reliable differentiation between peripheral and central etiologies. Video head impulse test (vHIT) is a new method that is based on the examination of rotational vestibulo-ocular reflex. vHIT has demonstrated high specificity for peripheral vestibular damage. Several studies have shown a broad applicability for vHIT, with an emphasis on potential use in the emergency department. It has been called “eye ECG” due to the speed and simplicity of this method use in AVS. However, vHIT is not a replacement for other methods in vestibular testing battery, rather their supplement. As a part of the HINTS (Head impulse, Nystagmus, Test of Skew) protocol it has shown higher sensitivity and specificity than diffusion weighted brain MRI in the detection of stroke with isolated vertigo. It is still under-utilized in the emergency department compared to the potential benefits it carries.

Abstract in Croatian

U dijagnostici akutnoga vestibularnog sindroma (AVS) nužno je brzo i pouzdano razlikovanje između perifernih i centralnih uzroka. Novost u dijagnostici AVS-a jest metoda video head impulse testa (vHIT), koja se temelji na testiranju rotacijskog vestibulo-okularnog refleksa. vHIT je pokazao visoku specifičnost za periferno vestibularno oštećenje, ali i nešto nižu osjetljivost u usporedbi s kalorijskim testiranjem, što mu je glavna mana. Dosadašnja istraživanja pokazala su višestruku primjenjivost ove metode s naglaskom na potencijalnoj primjeni u hitnoj službi. Zbog svoje brzine i jednostavnosti primjene ova metoda naziva se i „očni EKG“. Ipak, metoda vHIT nije zamjena za dosadašnje metode testiranja vestibularnog sustava, već njihova nadopuna. U sklopu protokola HINTS (engl. Head impulse, Nystagmus, Test of Skew) pokazala je višu osjetljivost i specifičnost od difuzijskih sekvencija MR-a mozga pri detekciji moždanog udara s izoliranom vrtoglavicom. Primjena vHIT-a u hitnoj ambulanti i dalje je premalena u odnosu prema potencijalnoj dobiti koju ona donosi.
