| 目的 利用彩色多普勒超声(CDU)观察经导管超选择性动脉栓塞治疗颈动脉体瘤(CBT)后的外科切除时机。方法 对22例外科切除术前CBT患者行经导管超选择性肿瘤供血动脉栓塞。于栓塞术前、术后1、2、4天分别采用CDU检测肿瘤供血动脉的峰值血流速度(PSV)和阻力指数(RI),并进行统计学分析。结果 栓塞术后1、2天,CBT供血动脉的PSV、RI均低于术前(P均<0.01),而栓塞术后4天PSV、RI与术前比较差异无统计学意义(P均>0.05)。结论 CDU对判断CBT侵犯范围、供血血管、侧支循环状况及选择手术时机均具有临床应用价值。栓塞术后2天内可能为安全切除CBT的手术时机。 |

| Objective To investigate the opportunity choice of surgical resection of carotid body tumor (CBT) after transcathter superselective embolization of feeding artery with color Doppler ultrasound observation (CDU). Methods Transtheter embolization of tumor feeding artery was performed on 22 CBT patients before surgical operation. CDU was used to measure the peak systolic velocity (PSV) and resistance index (RI) of blood flow of feeding artery before and 1, 2, 4 days after embolization, respectively. Statistical analysis of these data was performed. Results One and 2 days after embolization, PSV and RI of tumor feeding artery were lower than those before embolization (both P<0.01), while no difference of PSV nor RI was found 4 days after embolization (both P>0.05). Conclusion CDU is valuable for the judgment of involvement aera, feeding artery and collateral pathways of CBT, as well as for the opportunity choice of surgical resection. Surgical resection of CBT may be safely performed within 2 days after transtheter superselective arterial embolization of feeding artery. |
