目的 探讨旋转肾动脉DSA临床应用的可行性。方法 回顾性分析 48例肾肿瘤患者腹主动脉DSA检查中肾动脉的解剖情况。测量 5 0例腹部CT增强扫描肾动脉开口的位置、方向。观察 16例旋转肾动脉DSA的效果。结果 48例常规腹主动脉DSA中 ,右肾动脉开口、主干及分支显示不清分别为 12例、5例及 10例。左肾动脉开口、主干及分支显示不清分别为 8例、4例及 6例。 5 0例腹部CT增强扫描显示 :右肾动脉开口位于腹主动脉侧壁、侧前壁以及侧后壁分别为 4例、2 4例及 3例。左肾动脉开口位于腹主动脉侧壁、侧前壁以及侧后壁分别为 13例、2例及 13例。两肾动脉开口位于腹主动脉同一水平面 11例。 16例旋转肾动脉DSA中 ,两侧肾动脉旋转 6例 ,单侧肾动脉旋转 10例。肾动脉开口狭窄 3例 ,主干狭窄 2例 ,肾肿瘤供血动脉 7例 ,排除肾动脉狭窄 4例。结论 旋转肾动脉DSA有助于详细显示肾动脉的解剖细节。
Objective To investigate the feasibility of clinical application of revolving renal artery DSA. Methods A retrospective analysis of 48 cases of renal tumor DSA examination of the abdominal aorta in the anatomy of the renal artery. Fifty cases of abdominal CT scan enhanced renal artery opening position, direction. To observe the effect of DSA in 16 cases of revolving renal artery. Results 48 cases of conventional abdominal aorta DSA, right renal artery opening, trunk and branches were unclear were 12 cases, 5 cases and 10 cases. Left renal artery openings, trunk and branches were unclear, respectively, 8 cases, 4 cases and 6 cases. 50 cases of abdominal CT enhanced scan showed: the opening of the right renal artery located in the abdominal aorta, anterior and posterior wall were 4 cases, 24 cases and 3 cases. The opening of the left renal artery was located in the side of the abdominal aorta, anterior and posterior wall were 13 cases, 2 cases and 13 cases. Two renal artery openings located in the same level of the abdominal aorta in 11 cases. DSA in 16 cases of revolving renal artery, both sides of the renal artery rotation in 6 cases, unilateral renal artery rotation in 10 cases. 3 cases of renal artery stenosis, 2 cases of stenosis, 7 cases of renal tumor and 4 cases of renal artery stenosis. Conclusion Rotating the renal artery DSA helps to detail the anatomy of the renal artery.
