Bevezetés: A boka-kar index meghatározása során az oszcillometriás eszközök a hagyományos Doppler-elven működő eszközökkel összevetve több ígéretes előnyt mutatnak. A speciális képzés szükségtelensége, a gyorsabb kivitelezés, valamint a mérés operátortól független volta sorolható ezek közé. Célkitűzés: A boka-kar index oszcillometriás és a Doppler-elven működő meghatározásának összehasonlító elemzése. Módszer: A vizsgálati egyének esetében folyamatos hullámú Doppler és automata oszcillometriás (BOSO ABI-system 100) módszerrel a boka-kar index egyidejű meghatározását végeztük. Az összehasonlító elemzés Bland−Altman- és ROC-analízis alkalmazásával történt. Eredmények: A két módszerrel végzett vizsgálat (734 mérés) jó egyezést mutatott a boka-kar index tartomány 0,9 értékéhez közel. Ezen érték alatt és felett az egyezés mértéke csökkent. Az oszcillometriás mérés során optimálisnak tekinthető diagnosztikus boka-kar index határérték 0,96 volt. Következtetések: A boka-kar index oszcillometriás meghatározása nem helyettesíti a Doppler-alapú mérést a teljes boka-kar index tartományban. Mindazonáltal a hatékony diszkriminációs tulajdonságának köszönhetően a tünetmentes egyének szűrésekor hathatós eszköz lehet. Orv Hetil. 2018; 159(5): 176–182.
