| 目的 采用256层MSCTA观察肾癌患者肾动脉解剖及肿瘤供血动脉情况,为肾癌患者术前评估提供影像学信息。方法 回顾性分析56例经手术后病理确诊的肾癌患者(肾癌组)及300例非肾癌患者(对照组)肾动脉CTA资料,采用VR及MPR技术重建肾动脉图像,观察肿瘤供血动脉形态改变、肿瘤与肾动脉空间解剖关系及肿瘤肾外迷走供血动脉情况;比较肾癌组及对照组肾动脉解剖及变异差异。结果 肾癌组肿瘤位于左肾者31例、位于右肾者24例、双肾癌1例,肿瘤最大径(5.86±2.48)cm;肾动脉主干及分支、肾盂、肾静脉呈各种受压、受侵改变;患侧肾动脉直径分别为左侧(7.14±0.72)mm、右侧(7.04±0.70)mm,较对照组 明显增粗(P<0.05);共发现肿瘤肾外迷走供血动脉27支,分别来自脾动脉、肠系膜下动脉、膈下动脉、肾包膜动脉、肝动脉、腰动脉及肠系膜上动脉。肾癌组肾动脉变异率与对照组比较差异无统计学意义 |

| Objective To observe the renal artery anatomy and tumor feeding arteries in patients with renal cell carcinoma using 256-slice CT angiography, and to provide preoperative image information for renal cell carcinoma patients. Methods Renal artery CTA data of 56 patients with renal cell carcinoma confirmed by pathology (renal cancer group) and 300 non-renal cancer patients (control group) were retrospectively analyzed. VR and MPR were used to reconstruct renal artery images to observe the tumor feeding of kidney artery morphological changes, the spatial anatomical relationship of tumor and renal artery anatomy, and the situation of the vagus arteries of the tumor. The incidence rate of renal artery anatomy variation was compared between renal cancer group and control group. Results In renal cancer group, the tumor located on the left kidney in 31, on the right kidney 24, and on bilateral kidney in 1 case. The average maximum size of the masses was (5.86±2.48)cm, the main renal artery and the branches, the renal pelvis and the renal vein showed a variety compressed and invaded changes. The diameter of renal artery on the lesion side was (7.14±0.72)mm (left) and (7.04±0.70)mm (right), which was more thicker than normal renal artery (left: mm, right:, P<0.05). Totally 27 feeding arteries to the tumor were found outside from kidney as follows: Splenic artery, inferior mesenteric artery, inferior phrenic artery, lumbar artery, superior mesenteric artery, hepatic arterial and renal capsular artery. There was no difference in mutation rate of renal artery between renal cancer group and control group (44.64% vs 41.67%, P>0.05). Conclusion The performance of tumor vascular morphology of renal cell carcinoma are complex, and the feeding arteries to the mass outside kidney sources diversely, which can be detected by 256-slice spiral CTA accurately. |
