摘　　要：目的探讨多层螺旋CT血管造影(CTA)对血管压迫所致肾盂输尿管连接部梗阻(UPJO)中的诊断价值。方法分析手术证实的16例血管压迫所致UPJO患者的CT血管造影图像,观察有无肾脏血管变异,肾盂输尿管连接部周围有无骑跨血管、血管的起源、大小及其与UPJO间的关系。结果 16例UPJO中,肾动脉解剖变异12例,肾静脉解剖变异3例。CTA16例见19支血管压迫,其中动脉血管15支,静脉血管4支。单支血管压迫13例,双支血管压迫3例,包括副肾动脉12例,迷走动脉3例,性腺静脉2例,副肾静脉2例。均与手术病理相吻合。结论多层螺旋CTA不但能够了解肾脏血管解剖及变异,并且在血管压迫所致UPJO的诊断及手术治疗方面具有重要价值。Objective To evaluate the diagnosis values of multi-slice CT angiography （CTA） in patients with ureteropelvic junction obstruction （UPJO） caused by aberrant crossing vessels. Methods 16 patients with surgically proved UPJO caused by aberrant crossing vessels were included. Their CTA findings were retrorespectively analyzed to observe the variants of renal vessels, presence, origin and size of crossing vessels surrounding ureteropelvic junction, Results Of 16 patients, 12 had variants of renal artery and 3 had variants of renal veins. A total of 19 aberrant crossing vessels were found in 16 patients. 15 of these vessels were arteries and 4 were veins. Solitary vessel was found in 13 patients and 2 vessels were found in 3 patients. Of the 19 vessels, 12 were accessory renal arteries, 3 were aberrant arteries, 2 were gonadal veins, and 2 were accessory renal veins. CTA fmdings of 16 cases were corresponded to their surgical pathology. Conclusion Multi-slice CTA not only reveals the anatomy of the renal vessels and its vascular variants, but also plays vital roles in the diagnosis and preoperative assessment of patients with UPJO caused by aberrant crossing vessels.
