摘要
目的: 总结15 例间隔旁路的射频消融结果。方法: 将间隔旁路区分为前间隔旁路,左、右中间隔旁路以及左、右后间隔旁路; 然后对不同部位旁路的射频消融方法进行分析。结果: 前间隔旁路1 例、左中间隔旁路1 例、右中间隔旁路2 例、左后间隔旁路6 例及右后间隔旁路5 例。所有病例均一次消融成功, 均未发生房室传导阻滞; 2 例左后间隔旁路在冠状静脉窦内消融成功。随访2 个月~38 个月, 无心动过速复发。结论: 射频导管消融术是阻断间隔旁路的安全有效的方法。
Objective:To analyze the results of radiofrequency ablation in 15 patients with septal accessory pathways.Methods:Septal accessory pathways were divided into aneroseptal ones,left and right midseptal ones,and left and right posteroseptal ones.The radiofrequency ablation methodology in different septal accessory pathways were analyzed.Results:Anteroseptal region in one patient,left midseptal in one,right midseptal in two,left posteroseptal in six,and right posteroseptal in five.All patients underwent successful ablation in the first procedure without atrioventricular block.Left posteroseptal accessory pathways in two patients were ablated within the coronary sinus.No recurrences of tachycardia occurred during a mean follow up of 20 months.Conclusion:The radiofrequency catheter ablation is a safe and eftective method for the curative therapy of septal accessory pathways. Subject headings:catheter ablation;heart block;bundle of Hise based on SGI INDIGO2 workstation. It worked with a nice and friendly graphical interface; could input and manage patient's details; extract external contours automatically and determine contours of target or ROIs interactively; reconsf interest within skull, at the same time of contour drawing; determine automatically or interactively the parameters of focuses, such as number, position, collimator size, source distribution etc; make dose prescription at the point of maximum dose or at any other reference point and make out automatically the precise treatment time for each focus. To make GAMMA TPS safer or for the sake of evaluation and scientific research, it provided the user with kinds of verification tools, such as volumetric dose distribution, Beam's Eye View, Dose Volume Histograms, isodose contours, isodose surfaces, dose summary table, magnifier etc. As a result, it exported the treatment plan by means of laser jet printer. We presented the essential concepts of our treatment planning approach, and illustrated these in a clinical case.
