目的:探讨肾动脉CT血管造影(Computed Tomography angiography,CTA)在肾脏肿瘤出血介入栓塞治疗中应用的临床效果。方法:28例肾脏患者在介入栓塞治疗前行肾动脉CTA检查。在介入手术中寻找所有的肿瘤供血动脉,并逐一进行栓塞治疗。栓塞治疗一周后复查肾动脉CTA检查。对肾动脉CTA在介入栓塞治疗中应用效果进行回顾性总结评价。结果:28例肾脏肿瘤出血患者在介入栓塞治疗前行肾动脉CTA检查,共找到32支肿瘤供血动脉,介入手术中共找到34支肿瘤供血动脉并成功栓塞治疗。介入手术前肾动脉CTA检查诊断的准确率为94.12%(32/34)。栓塞治疗后复查肾动脉CTA检查证实所有已栓塞的肿瘤供血动脉栓塞效果良好。结论:介入栓塞治疗前肾动脉CTA检查可以为肾脏肿瘤出血介入栓塞治疗提供准确的定位作用。栓塞治疗后肾动脉CTA检查有利于对栓塞疗效的准确判定。
Objective: To investigate the clinical effect of Computed Tomography angiography (CTA) in renal artery embolization in the treatment of renal tumors. Methods: 28 cases of renal patients underwent CTA before renal artery embolization. In the interventional operation to find all the tumor feeding artery, and embolization treatment. One week after embolization, renal artery CTA examination was performed. Renal artery CTA interventional embolization in the application of retrospective evaluation. Results: Twenty-eight patients with renal tumor hemorrhage underwent renal artery CTA before interventional embolization. A total of 32 tumor-supplying arteries were found. During the interventional procedure, 34 tumor-supplying arteries were found and were successfully embolized. The diagnostic accuracy of CTA before interventional surgery was 94.12% (32/34). Renal CTA examination after embolization treatment confirmed that all embolized tumors had a good arterial embolization. Conclusion: Interventional embolization before renal artery CTA examination can provide accurate positioning for interventional embolization of renal tumor hemorrhage. Embolization of renal artery CTA examination is conducive to accurate assessment of the efficacy of embolization.
