Short-term follow-up angiographic evaluation of renal artery stenoses treated by means of percutaneous transluminal renal angioplasty was performed in 89 patients with 108 treated stenoses, at a mean of 5.9 months +/- 6.7 after the procedure. In 72 patients intravenous digital subtraction angiography was performed; in 17 patients intraarterial digital subtraction angiography was performed. Indications for the study were (a) routine follow-up in 31 patients, (b) residual hypertension in 16, (c) residual stenosis on the postdilation angiogram (with residual hypertension) in 17, and (d) relapse of hypertension in 25. In 16 of the 25 patients (64%) with relapse of hypertension, angiography showed relapse of stenosis or occlusion of the vessel. In nine of the 17 patients (53%) with residual stenosis on the postdilation angiogram, an improvement in the angiographic appearance of the lesion was noted. Residual stenosis was noted in one normotensive patient, in three patients with residual hypertension, and in eight patients with residual stenosis on the postdilation angiogram.
对89例患者的108处经皮腔内肾血管成形术治疗的肾动脉狭窄进行了短期随访血管造影评估，平均在术后5.9个月±6.7个月进行。72例患者进行了静脉数字减影血管造影；17例患者进行了动脉数字减影血管造影。该研究的指征为：(a) 31例患者的常规随访，(b) 16例患者的残余高血压，(c) 17例患者扩张后血管造影显示残余狭窄（伴有残余高血压），以及(d) 25例患者的高血压复发。在25例高血压复发患者中的16例（64%）中，血管造影显示血管狭窄复发或闭塞。在17例扩张后血管造影显示残余狭窄的患者中的9例（53%）中，病变的血管造影表现有所改善。在1例血压正常的患者、3例有残余高血压的患者和8例扩张后血管造影显示残余狭窄的患者中发现有残余狭窄。
