256层螺旋CT肾动脉成像在腹腔镜肾脏手术中的应用价值

Clinical application of renal vessel angiography with 256-slice spiral CT in laparoscopic surgery for renals

目的评价。肾动脉256层螺旋cT三维血管造影（CTA）在腹腔镜。肾脏手术术前评估中的价值。方法155例行腹腔镜肾脏手术患者术前行肾动脉CTA，根据术前CTA所显示的肾动脉情况，初步计划术中处理肾动脉的情况，最后与实际手术情况相比较。结果所有患者术前肾动脉CTA结果与实际手术所见符合率100％。CTA的影像立体感强，很好地反映了肾血管的解剖结构和异位血管走行。结论CTA能准确评价。肾动脉的走形和变异情况，对于术中快速、准确的处理肾动脉，减少术中出血及损伤等并发症有重要意义。

Objective To investigate the clinical application of renal vessel angiography with 256-slice spiral CT in laparoscopic surgery for renals. Methods One hundred and fifty-five cases underwent computed tomograph angiography（CTA） who were all confirmed by operations. According to preoperative renal artery CTA case shown, the initial plan intraoperative renal artery was compared with the situation with the actual surgery. AI1 axial images were reconstructed using technique. Results All patients underwent preoperative renal artery CTA operative findings correspond with the actual rate of 100%. CTA stereoscopic images were good at reflecting renal vascular anatomy and ectopic blood vessels line. Conclusion CTA can accurately evaluate out of shape and variation of the renal arteriesvariation. It has important significance of processing of renal arteries intraoperative rapid, dealing with the renal artery accurately and reducing blood loss or damage and other complications.
