目的探讨心房颤动(简称房颤)射频消融治疗中通过选择性上肺静脉造影显示下肺静脉开口位置的可行性与效果。方法97例房颤患者,取左前斜位(LAO)50°和右前斜位(RAO)50°两个体位进行左上肺静脉造影。取LAO50°及RAO30°两个体位进行右上肺静脉造影。结果97例(100%)均可通过选择性左上肺静脉造影清晰显示左下肺静脉开口的下缘,其中78例(80.4%)可以清晰显示左下肺静脉的开口前缘。79例(81.4%)患者可以清晰显示左下肺静脉开口的后缘。选择性右上肺静脉造影时,86例(88.7%)能够清晰识别右下肺静脉开口下缘,76例(78.4%)能清晰显示右下肺静脉开口前缘,81例(83.5%)能清晰显示右下肺静脉开口后缘。结论选择性上肺静脉造影不仅能够显示上肺静脉的开口位置,而且在大部分患者中亦能较清晰显示下肺静脉的开口解剖。
Objective To investigate the feasibility and effect of selective upper pulmonary venous angiography in radiofrequency ablation of atrial fibrillation (AF). Methods A total of 97 patients with atrial fibrillation were enrolled in the study. Left anterior oblique (LAO) 50 ° and right anterior oblique (RAO) Take LAO50 ° and RAO30 ° two positions for right upper pulmonary vein angiography. Results All the 97 cases (100%) could clearly show the lower edge of the left lower pulmonary veins through the selective left upper pulmonary vein venography. Among them, 78 cases (80.4%) clearly showed the leading edge of the left lower pulmonary vein. 79 patients (81.4%) patients can clearly show the posterior edge of the left lower pulmonary vein openings. In the selective right upper pulmonary vein angiography, 86 cases (88.7%) clearly identified the inferior border of the right lower pulmonary veins and 76 cases (78.4%) clearly showed the leading edge of the right lower pulmonary vein and 81 cases (83.5%) clearly showed the lower right Pulmonary veins open trailing edge. Conclusion The selective upper pulmonary venous angiography can not only show the position of the opening of the upper pulmonary veins, but also can clearly show the anatomy of the lower pulmonary veins in most patients.
