摘要

摘要: 目的:探讨炫速双源CT在左心耳(LAA)解剖结构及毗邻关系评价中的应用价值。方法:回顾性分析行冠状动脉扫描的62例窦性心律患者及行左心房增强扫描的21例房颤组患者的临床及影像学资料,观察左心耳与肺静脉的关系,对左心耳各径线进行定量测量,并对两组间数据进行比较。结果:房颤组患者与对照组肺静脉变异率及左心耳与左上肺静脉位置关系比较差异无统计学意义(P>0.05)。房颤组左心耳口部长短径、面积、容积及第一转折角度与对照组比较差异有统计学意义(P<0.05)。结论:炫速双源CT可以对左心耳各径线进行定量测量,并可清晰显示其相邻解剖结构,对射频消融术及左心耳封堵术具有重要的指导意义。

Abstract: Objective: To study the relationship and morphological assessment of left atrial appendage (LAA) and adjacent anatomical structure by SOMATOM Definition Flash CT. Methods: 83 patients were selected retrospectively including 62 patients with sinus rhythms underwent coronary angiography and 21 patients with atrial fibrillation underwent left atrial enhancement scanning. The relationship between the LAA and the pulmonary vein was observed, and the diameter of the left atrial appendage was measured quantitatively. Then the data between the two groups were compared. Results: There was no significant difference in pulmonary vein variation rate and anatomical relationship of the LAA to left superior pulmonary vein (LSPV) between the atrial fibrillation patients and the control group (P > 0.05). And there were significant differences in the length, area, volume and the first turning angle of LAA in the two groups (P < 0.05). Conclusion: SOMATOM Definition Flash CT scan can quantitatively measure the diameter of LAA, and it can also clearly show the correlation of LAA and its adjacent anatomy. So it may have an important guiding significance for atrial fibrillation ablation and LAA occlusion.
