摘　　要：目的探讨炫速双源CT血管造影左心房憩室影像学表现及临床意义。方法266例受检者行冠状动脉血管造影,观察左心房憩室位置、形态,测量憩室颈部直径及体部长度、憩室房壁及正常左心房壁厚度。结果检出左心房憩室34例,发生率12.8%,发生率在不同性别、年龄组间差别无统计学意义(P>0.05);憩室房壁厚度为(0.86±0.21)mm,相邻左心房壁厚度为(1.29±0.31)mm,两者间差别有统计学意义(P<0.05)。结论炫速双源CT血管造影可清晰再现左心房憩室的位置、大小、形态、与周围组织的关系,对外科治疗术前方案的制定具有重要意义。Objective To investigate imaging manifestations and clinical significance of left atrial diverticulum with dual-source CT(Somatom Definaton Flash)angiography.Methods 266 cases were subjected to client coronary artery angiography.We observed position and shape left atrium diverticulum and measured the diverticulum neck diameter and body minister,diverticulum room wall and normal left atrial wall thickness.Results 34 cases of left atrial diverticulum were detected,the presence probability of left atrial diverticulum was 12.8%.There was no difference on gender and age(P>0.05);the thickness of diverticulum wall was(0.86±0.21)mm,the thickness of nomal left ventricular wall was(1.29±0.31)mm,there was a significant difference between them.Conclusion Dual-source CT(Somatom Definaton Flash)angiography can clearly represent the position,size,shape of left atrial diverticulum,and anatomical relationships with the surrounding tissue,which is important significance for preoperative plan formulation of the surgical treatment.
