【摘要】： 目的:①通過64層螺旋CT對成人冠狀動脈直徑、冠狀動脈分叉角度及冠狀動脈開口與主動脈根部間距離的測量,探討冠狀動脈與年齡之間的關(guān)系及在臨床的應(yīng)用。②分析冠狀動脈主干分叉角度與斑塊形成的相關(guān)性。材料與方法:①選取行64層螺旋CT檢查,結(jié)果正常者共142例,按不同性別、年齡分成5組。將原始圖像在圖像后處理工作站上重建出冠狀動脈的最大密度投影(MIP)圖像和容積重建(VRT)圖像。在單層橫斷面上測量管腔直徑,在MIP圖像上進(jìn)行角度及距離測量。②另選取55例臨床疑似或確診患有冠心病病例的64層螺旋CT的冠狀動脈造影(CTA)圖像,進(jìn)行冠狀動脈左主干分叉角度的測量。所有統(tǒng)計采用SPSS11.0軟件進(jìn)行分析。結(jié)果:1.直徑:男性①右冠狀動脈:31-40年齡與61-70組之間、41-50年齡組與61-70歲組之間、31-40年齡組與71-年齡組之間、41-50年齡組與71-年齡組的直徑值之間存在顯著統(tǒng)計學(xué)差異(P＜0.05);②左前降支:31-40年齡組與61-70年齡組及71-年齡組之間,存在顯著統(tǒng)計學(xué)差異(P＜0.05);③左回旋支:31-40年齡組與61-70年齡組之間,31-40年齡組與71-年齡組之間存在顯著統(tǒng)計學(xué)差異(P＜0.05)。女性①右冠狀動脈:31-40年齡組與71-年齡組之間、41-50年齡組與71-年齡組的直徑值之間存在顯著統(tǒng)計學(xué)差異(P＜0.05);②左前降支:31-40年齡組與71-年齡組之間、51-60年齡組與71-年齡組之間存在顯著統(tǒng)計學(xué)差異(P＜0.05);③左回旋支:31-40年齡組與61-70組之間、41-50年齡組與61-70歲組之間、31-40年齡組與71-年齡組之間、41-50年齡組與71-年齡組的直徑值之間存在顯著統(tǒng)計學(xué)差異(P＜0.05)。2.不同年齡組中,冠狀動脈與主動脈間,左前降支與左回旋支間的角度及左、右冠狀動脈開口至主動脈根部距離之間無顯著統(tǒng)計學(xué)差異(P＞0.05)。3.對于同一年齡組,性別間測量值無顯著統(tǒng)計學(xué)差異(P＞0.05)。4.左前降支近段有斑塊患者中,左冠狀動脈主干分叉角度＞78.5°與左冠狀動脈主干分叉角度＜78.5°兩組之間有顯著差異(P＜0.05);左回旋支近段有斑塊患者中,左冠狀動脈主干分叉角度＞78.5°與左冠狀動脈主干分叉角度＜78.5°兩組之間無顯著差異(P＞0.05)。結(jié)論:年齡與冠狀動脈的直徑之間存在著負(fù)相關(guān)性;左冠狀動脈主干分叉角度對冠狀動脈粥樣硬化斑塊的形成起重要的影響作用。
[Abstract]:Objective to measure the diameter of coronary artery, the angle of coronary artery bifurcation and the distance between coronary artery opening and aortic root by 64-slice spiral CT. To explore the relationship between coronary artery and age and to analyze the correlation between coronary artery bifurcation angle and plaque formation. Results 142 cases were normal, according to sex. Age was divided into 5 groups. The original image was reconstructed on the image post processing workstation with maximum density projection (MIP) image and volume reconstruction (VRT) image. The diameter of the lumen was measured on a single cross section. Angle and distance were measured on MIP images. Another 55 patients with suspected or confirmed coronary heart disease were selected for 64-slice spiral CT coronary angiography. The angle of left main coronary artery bifurcation was measured. All statistics were analyzed by SPSS11.0 software. Results: diameter: male 1 right coronary artery:. 31-40 age group and 61-70 group. Between the 41-50 age group and the 61-70 age group, the age group 31-40 and the 71-age group. There was significant difference in diameter between 41-50 age group and 71-age group (P < 0.05). (2) there was a significant difference in the left anterior descending branch between the 31-40 age group and the 61-70 age group and the 71-age group (P < 0. 05); 3The left circumflex branch: 31-40 age group and 61-70 age group. There was significant statistical difference between 31-40 age group and 71-age group (P < 0.05). Female 1 right coronary artery: 31-40 age group and 71-age group. There was significant difference in diameter between 41-50 age group and 71-age group (P < 0.05). (2) there was significant statistical difference between 71-60 and 71-60 age groups in the left anterior descending branch (P < 0.05). 3The left circumflex branch was between the age group of 31-40 and the group of 61-70, and the age group of 41-50 and the age group of 61-70 years, between the age group of 31-40 and the age group of 71-70. There was significant difference in diameter between 41-50 age group and 71-age group (P < 0.05). There was significant difference between coronary artery and aorta in different age groups. There was no significant difference in the angle between the left anterior descending branch and the left circumflex branch and the distance between the opening of the left and right coronary artery and the root of the aorta (P > 0.05. 3) for the same age group. There was no significant statistical difference between sexes (P > 0.05). 4. In patients with plaque in proximal segment of left anterior descending branch. There was significant difference between the two groups in the angle of main coronary artery bifurcation > 78.5 擄and the angle of left main coronary artery bifurcation < 78.5 擄(P < 0.05). In patients with plaque in the proximal segment of the left circumflex branch. There was no significant difference between the left coronary artery shunt angle > 78.5 擄and the left coronary artery bifurcation angle < 78.5 擄(P > 0.05). Conclusion: there is a negative correlation between age and coronary artery diameter. The angle of bifurcation of left coronary artery plays an important role in the formation of coronary atherosclerotic plaque.
