作者报告了11例仅单肾有功能的病人行肾动脉经皮经腔血管成形术(PTRA)以矫正肾血管性高血压或保存肾功能。男5例,女6例,年龄42～81岁。11例肾动脉硬化性狭窄截面积减少75～99%。9例有肾功能减退。PTRA前记录2～3次基线血压,术后记录随访血压。若病人舒张压较基线者至少降低10mmHg或在90mmHg以下,及不再需用降压药者视为治愈。若病人血压降低至90mmHg或更低,但仍需用降压药者视为改善。若肌酐水平降至0.4mg/dl或更低视为肾功能改善。9例完成PTRA者随访2～180周。操作从股动脉进路,扩张前动脉注入3000μ肝素,均应用两步法调
The authors reported that renal artery percutaneous transluminal angioplasty (PTRA) was performed in 11 patients with only single renal function to correct either renovascular hypertension or renal function. 5 males and 6 females, aged 42 to 81 years old. 11 cases of renal artery sclerosis cross-sectional area decreased by 75 ~ 99%. Nine cases had renal dysfunction. PTRA before the record 2 to 3 times the baseline blood pressure, postoperative follow-up blood pressure. If the patient diastolic blood pressure lower than baseline at least 10mmHg or 90mmHg below, and no longer need to use antihypertensive drugs were considered as cure. If the patient’s blood pressure dropped to 90mmHg or lower, but still need antihypertensive drugs were considered as improvement. A decrease in creatinine level of 0.4 mg / dl or less is considered as an improvement in renal function. Nine patients who completed PTRA were followed up for 2 to 180 weeks. Operation from the femoral artery approach, pre-dilated artery injection of 3000μ heparin, are applied two-step method
