The radiofrequency ablation effect was observed in 21 patients with single right atrioventricular accessory pathway by superior vena cava approach. Because of many factors, radiofrequency ablation by routine inferior vena cava approach failed. However, all of these accessory pathways were successfully ablated by the superior vena cava approach with could significantly reduce operation and radiofrequency ablation time and exposed time in x-ray, and there were not any complications. The success was probably related to the good contact between the ablation catheter tip and ablation target point. It is suggested that radiofrequency ablation of right atrioventricular accessory pathways by superior vena cava approach is effective and safe when the routine inferior vena cava approach is difficult or unsuccessful.
采用上腔静脉途径对21例单纯右房室旁道患者进行了射频消融治疗。由于多种因素，经常规下腔静脉途径射频消融失败。然而，所有这些旁道均用上腔静脉途径成功消融，该途径可显著缩短手术及射频消融时间和X线下曝光时间，且无任何并发症。成功可能与消融导管尖端与消融靶点良好接触有关。提示当常规下腔静脉途径困难或失败时，经上腔静脉途径射频消融右房室旁道有效且安全。
