Abstract
Background: Intravascular Ultrasound (IVUS) has been being an effectively supportive tool at Cathlab. Objectives: We perform this study in order to evaluate the role of IVUS in coronary lesions. Method: All patients, who were treated at Choray hospital from 10/2009 to 10/2013 and had indication for IVUS, were enrolled in this study. This was a cross-sectional prospective study. Results: A total of 46 patients, in which male patients was 63%, was used IVUS procedure to evaluate coronary artery lesions. IVUS provided an exact and diffferent information about: lesion length (20,17 ± 6,43mm sv 17,39 ± 6,79mm; p < 0,001), reference vessle diameter (3,13 ± 0,60mm sv 2,81 ± 0,49mm; p < 0,001), minimal lumen area (3,19 ± 0,67mm2 sv 1,60 ± 0,98mm; p < 0,001) respectively when compared with coronary angiography. IVUS is a powerful tool for evaluating ostial lesions 4,35% (2/46); superficial cancification 19,56% (9/46); mural thrombus 2,17% (1/46) and vulnerable lesions 2,17% (1/46) in which coronary angiography can not reveal. There was no IVUS related complications documented. Conclusion: IVUS is an effective and safe tool in evaluation of coronary artery lesion. Key words: Coronary lesion, IVUS, angiography
