螺旋CT肾动脉成像在腹腔镜肾部分切除术中的应用

目的：探讨术前肾血管CT血管成像（CTA）在指导腹腔镜下肾部分切除术中血管处理的作用。方法：15例患者中肾癌9例，肾错构瘤6例。术前均行。肾血管CTA。经腹膜后入路施行腹腔镜肾部分切除术，术中根据CTA提示寻找并阻断肾动脉。结果：CTA示肾门前肾动脉分支3例，占总病例数20％。副肾动脉1例，占总病例数6．7％。术中探查均发现CTA所提示的异常血管，探查未发现其他异常动脉。本组15例全部手术成功。结论：CTA能清楚显示血管的解剖及变异，为术中处理肾动脉提供有效的指导。

The Application of Spiral CT Arteriorenal Angiography in Laparoscopic Partial Nephrectomy

Objective：To discuss preoperative renal vascular CTA in guiding the vascular treatment during laparoscopic partial nephrectomy. Methods：This group of 15 cases, 9 cases of renal cell carcinoma, renal angiomyolipoma 6 cases. Preoperative Renal vascular CTA were performed. All the cases underwent retroperitoneal laparo- scopic partial nephrectomy and search for arteriorenal variants according to CTA tips. Results：Of all the spiral CT angiography, proximal arterial branches were found in 20% ,3 cases, 6.7% was accessory renal artery, one cases. All the operations （15 cases） were successful, arteriorenal anatomical variants in CTA were confirmed by operations. Conclusions： Arteriorenal anatomical variants can be clearly displayed by preoperative spiral CT angiography. It will be great help for the treatment of renal artery in partial nephrectomy.
