目的探讨多层螺旋CT血管成像(MSCTA)在活体肾移植供肾切除术前的应用价值。方法采用西门子公司双源CT设备对40例受检者行MSCTA检查,评估肾脏血管解剖及变异情况。结果40例80个肾脏中,MSCTA显示64个肾脏由单支动脉供血、67个肾脏由单支静脉引流、16个肾脏存在副肾动脉、11支主肾动脉存在过早分支、1例左肾上段动脉起始部局限性狭窄、1例肠系膜上动脉起始部局限性狭窄、1例左肾静脉中段见一血管袢。40例受检者中22例行供肾摘除术,术中所见供肾血管情况与MSCTA术前评估结果一致。结论MSCTA可准确显示受检者肾脏血管情况,可作为活体肾移植供肾术前血管评估的首选检查方法。
Objective To investigate the value of multislice spiral CT angiography (MSCTA) before nephrectomy for living donor kidney transplantation. Methods Forty subjects were examined by MSCTA with double-source CT equipment of Siemens to evaluate the anatomy and variation of renal blood vessels. Results Among the 80 nephrons in 40 cases, MSCTA showed that 64 kidneys were supplied with blood from a single artery, 67 kidneys were drained through a single vein, 16 kidneys had accessory renal arteries, 11 main renal arteries had premature branches, and 1 left kidney There was a limited stenosis at the beginning of the superior arteries, a limited stenosis at the beginning of the superior mesenteric artery, and a thrombosis at the middle of the left renal vein. Twenty-two cases of 40 subjects underwent enucleation of the kidneys, and the findings of intracoronary blood vessels were consistent with those of MSCTA preoperatively. Conclusion MSCTA can accurately show the renal blood vessels of the subjects, which can be used as the preferred method for preoperative assessment of the kidneys for donor kidney transplantation.
