ABSTRACT
BACKGROUND:
Patients (pts) scheduled for coronary artery bypass grafting, burdened with high risk of carotid stenosis, are recommended to undergo duplex ultrasonography (DUS) of carotid arteries.PURPOSE:
To validate pocket-size imaging device (PSID) equipped with linear probe as an easily accessible tool enabling bedside screening for carotid artery stenosis (CAS).METHODS:
A total of 100 pts (60 men, mean age 69±11 years) with multivessel coronary artery disease underwent bedside DUS of carotid arteries with the use of PSID performed by a cardiology resident trained in DUS. Subsequently, DUS with the use of stationary high-end ultrasound system was performed in all pts to verify findings of PSID examination.RESULTS:
Initial diagnosis of atherosclerotic plaque presence obtained with PSID in 59 patients was confirmed by high-end ultrasound system examination in all cases. There was a statistically significant correlation of intima-media thickness measurements between PSID and stationary system (r=.58; 95% CI 0.48-0.66; P<.0001), but the coefficient of agreement (κ) between the two methods in classification of intima-media as normal or thickened (>0.9 mm) was only .38 (95% CI 0.299-0.459). During PSID examination, turbulent flow was observed in 21 pts-CAS was confirmed in all these pts-5 pts were diagnosed with significant CAS, the rest with CAS ranging from 30% to 70%.CONCLUSIONS:
Pocket-size imaging device equipped with linear probe allows for identification of patients with atherosclerotic plaques and turbulent flow in carotid arteries; however, the degree of CAS cannot be reliably determined. The measurement accuracy of intima-media thickness is insufficient for a diagnostic purpose.Palavras-chave
