Abstract:
Objective To explore the potential relationship between left coronary bifurcation angle and plaques forming in left anterior descending artery by dual-source CT angiography.Methods One hundred patients who underwent dual-source CT angiography in our hospital from January to May during 2016 and had plaques in left anterior descending artery were retrospectively studied,while 100 patients with normal image were as negative controls.There were 57 male and 43 female at the mean age of (57.54 ±-8.38) years in negative controls,and 64 male and 36 female at the mean age of (62.08 ± 13.94) years in patients with left anterior descending artery plaques.The left coronary bifurcation angle was measured by multi-planar reconstruction (MPR) and maximum density projection (MIP) techniques.Results The left coronary bifurcation angle in negative control group were range from 41.25°to 112.14°,at the mean age of 69.45 ° ± 18.71 °,while range from 54.14 ° to 128.12 o,at the mean age of 85.65 °-± 15.96 ° in plaque group.The bifurcation angle in plaque group was larger than those in negative control group(P ＜ 0.05).Conclusion Dual-source CTA could objectively evaluate left coronary bifurcation angle and plaque character.The left coronary bifurcation angle had an important influence on the formation of left anterior descending artery plaque.
