Abstract
Objective To study the distribution and morphological features of atherosclerotic plaques detected by 16 -slice multi spiral CT ( MSCT ) coronary angiography. Methods Clinical data of 140 patients underwent MSCT coronary angiography from Feb. 2009 to May 2010 were analyzed. Results As for the 684 plaques detected by MSCT, 119 were non - calcified plaques. Plaques were most often seen in the LAD -6 segment ( 41 plaques ), followed by LAD -7 ( 20 plaques ), LCX 11 ( 13 plaques ) and RCA - 1 ( 13 plaques ). Coronary artery stenosis with degrees ≥50％ were found in 78 plaques, most of which were focal lesions ( ＜ 10 mm ), followed by tube - like lesions ( 10 ～ 20 mm ) and diffused lesions ( ＞ 20 mm ). Two dimensional and three dimensional reformation were performed on the 78 plaques. In 73 cases the stenosis were found to be eccentric ; 43 of them were found in the medial wall, while others were found in the lateral wall. Only 5 cases of stenosis were shown to be concentric. Conclusion ( 1 ) Incidence rate of atherosclerotic plaques is higher in the left coronary arteries than in the right ones and higher in the proximal segments than in the distal segments. Most plaques are focal or tube - like lesions. Most plaques are eccentricly shaped and prefer the medial wall better than the lateral wall ( with the exception of the LAD branch which displays similar plaque distribution in both the medial and the lateral walls ). Concentric plaques are rare. ( 2 ) Computed tomographic coronary angiography can effectively detect the degrees of coronary artery stenosis and the morphology of the atherosclerotic plaques . It could be applied in prevention and early diagnosis of coronary heart diseases.关键词
