目的:探讨CT血管成像技术对肾移植供肾术前评估的应用价值。方法:活体肾移植供肾者40例,均行64排螺旋CT血管成像,通过3个方面的评估(肾实质、肾血管、集尿系统)以明确供肾的临床移植价值。结果:40例供肾者均获得满意图像,18例显示4级分支,18例显示3级分支,4例显示2级分支。发现有副肾动脉者19例(47.5%),其中右肾有副肾动脉者11例,左肾有副肾动脉者6例,提前分支1例,双肾均有副肾动脉供血者1例;显示胡桃夹综合征1例。肾静脉未见畸形与变异。结论:64排螺旋CT血管成像技术能直观、准确评估肾实质、肾血管、集尿系统的实际情况,对活体肾移植供肾的评估准确、有效、无创、快捷、低廉。
Objective: To evaluate the value of CT angiography in the preoperative assessment of kidney transplantation. Methods: 40 cases of living donor kidney donor were treated with 64-slice spiral CT angiography. Three aspects of assessment (renal parenchyma, renal vascular, urine collection system) were used to clarify the clinical value of donor kidney transplantation. Results: Satisfactory images were obtained in 40 patients with kidney, 18 with 4 branches, 18 with 3 branches and 4 with 2 branches. There were 19 cases (47.5%) with accessory renal artery. There were 11 cases of accessory renal artery in right kidney, 6 cases of accessory renal artery in left kidney, 1 case of anterior branch in advance, 1 case of accessory renal artery in both kidneys One case showed Nutcracker syndrome. Renal vein no abnormalities and variations. Conclusion: The 64-slice spiral CT angiography can evaluate the real situation of renal parenchyma, renal blood vessel and urine collection system accurately and effectively, and it is accurate, effective, noninvasive, quick and inexpensive to evaluate the donor kidney of living kidney transplantation.
