作者对5例纤维肌性发育不良引起的灶性肾动脉窄狭的高血压患者,进行了肾动脉PTA。3例年龄为22、38和45岁的患者高血压史分别为3、5.5和20年,另2例不详;4例为单侧、1例为双侧肾动脉狭窄。主动脉造影显示在腹主动脉及其主要分支中均未见动脉粥样硬化。操作均经股动脉进行。依血管造影显示的血管直径选择球囊的直径。5例患者均用高压球囊导管并用-3 ml塑料注射器扩张球囊导管最大至10个大气压(10.1×10~5Pa),每例扩张两次。扩张术后3～12个月所有患者均行IV DSA,总随访期为7-16个月,结果表明,5例中有4例治疗效果满意,其中3例血液恢复正常或降低,扩张术后3～12个月的IV DSA显示无复发,1例用利尿剂后血压改善;另1例血压未改
The authors performed renal artery PTA on 5 patients with focal narrowing of renal artery due to fibromuscular dysplasia. Three patients aged 22, 38, and 45 years had histories of hypertension 3,5,5 and 20 years, respectively, and two others were unknown; four were unilateral and one was bilateral renal artery stenosis. Aortic angiography showed no signs of atherosclerosis in the abdominal aorta and its major branches. The operation is carried out by the femoral artery. Select the diameter of the balloon based on the vessel diameter shown by the angiogram. All 5 patients underwent balloon catheterization with a 3 ml plastic syringe using a high-pressure balloon catheter up to 10 atmospheres (10.1 x 10-5 Pa) with a double dilation in each case. IV DSA was performed in all patients 3 to 12 months postoperatively with a total follow-up of 7-16 months. The results showed that 4 of 5 patients were satisfactorily treated and 3 of them returned to normal or decreased blood flow. IV DSA of 3 to 12 months showed no recurrence, 1 case of blood pressure was improved with diuretics, and 1 case of unchanged blood pressure
