目的用于评价两种径路的血管成形术的方法对移植肾动脉狭窄的治疗作用。材料与方法 18例移植肾动脉狭窄并高血压患者成功进行了血管成形术。18例中,15例患者血管狭窄位于外科手术血管吻合处或吻合处远侧端移植肾动脉主干,3例位于移植肾的肾内分支动脉。同侧股动脉径路用于治疗端-侧血管吻合的患者(n=10),对侧股动脉径路,用于治疗端-端血管吻合的患者(n=6)。16例采用股动脉径路,2例经肱动脉径路。疗效以临床随访、血管造影和超声追踪为评价。结果 18例移植肾动脉狭窄患者成功地施行了血管成形术。成形术后,所有病人均治愈。1例患者因为复发动脉狭窄,而再次作血管扩张,同时放置1个支撑器。第二次血管成形术后6个月,考虑病人已治愈。结论血管成形术是移植肾动脉狭窄所致长期高血压和肾功能减退的有效的、首选治疗方法。
Objective To evaluate the therapeutic effect of two angioplasty methods on transplanted renal artery stenosis. Materials and Methods 18 cases of transplanted renal artery stenosis and hypertension were successfully performed angioplasty. Of the 18 patients, 15 had vascular stenosis at the distal end of the renal artery at the distal end of the vascular anastomosis or anastomosis, and 3 at the branch of the renal artery located in the renal graft. The ipsilateral femoral artery approach was used to treat patients with end-to-side vascular anastomosis (n = 10), contralateral femoral artery approach (n = 6) for end-to-end vascular anastomosis. 16 cases of femoral artery approach, 2 cases of brachial artery approach. The efficacy of clinical follow-up, angiography and ultrasound tracking for the evaluation. Results 18 patients undergoing renal artery stenosis were successfully treated with angioplasty. After surgery, all patients were cured. One patient had vasodilation again due to recurrent arterial stenosis with one supporter placed. Six months after the second angioplasty, consider the patient has been cured. Conclusion Angioplasty is an effective and preferred treatment for long-term hypertension and renal dysfunction caused by renal artery stenosis.
