目的研究经皮腔内血管成形术+内支架植入术治疗大动脉炎性肾动脉狭窄所致肾性高血压的临床效果。资料与方法选用Palmaz支架和AVEBridge支架,对18例大动脉炎所致肾动脉狭窄先行经皮腔内肾动脉成形术(PTRA),然后放置支架。术后检测血管的内径和术后一周时血压的变化。结果18例PTRA+支架植入术技术成功率100%。血管内径由术前平均为(1.7±0.6)mm恢复至术后为(5.3±0.4)mm,术后1周时血压由术前的(22.7±3.3/14.0±2.1)kPa降为(19.3±1.6/10.4±2.0)kPa,其中10例血压恢复正常,6例血压改善。术后随访肾动脉血流通畅,血压控制满意。结论PTRA+支架植入术治疗大动脉炎性肾动脉狭效果满意,创伤小,患者痛苦少;PTRA+支架术是目前治疗大动脉炎性肾动脉狭窄的首选方法,具有安全、简便、有效的优点。
Objective To study the clinical effect of percutaneous transluminal angioplasty and stent-graft in the treatment of renal hypertension caused by aortic arterial stenosis. Materials and Methods Palmaz stent and AVEBridge stent were used in this study. PTRA was performed on 18 cases of renal artery stenosis caused by arteritis and then stent was placed. Postoperative vascular diameter and blood pressure changes after a week. Results 18 cases of PTRA + stent implantation technology success rate of 100%. The mean intra-arterial diameter was (1.7 ± 0.6) mm from pre-surgery to (5.3 ± 0.4) mm postoperatively, and was decreased from (22.7 ± 3.3 / 14.0 ± 2.1) kPa to (19.3 ± 1.6 / 10.4 ± 2.0) kPa, of which 10 patients returned to normal blood pressure, 6 patients improved blood pressure. Follow-up Renal artery blood flow was smooth and blood pressure control was satisfactory. Conclusion PTRA + stent implantation for the treatment of small artery inflammation of the renal artery narrow satisfaction with less trauma, less pain patients; PTRA + stenting is the preferred method of treatment of aortic arterial stenosis of the preferred method with safe, simple and effective advantages.
