锁骨下动脉狭窄介入治疗20例随访分析

目的　总结采用两种介入方法治疗 2 0例锁骨下动脉狭窄患者的随访结果。方法　 2 0例有症状男性锁骨下动脉狭窄患者平均年龄 6 3 4岁 ,定量血管造影分析显示锁骨下动脉平均狭窄87% ,双上肢动脉收缩压差平均为 116mmHg。经右股动脉完成球囊血管成形术 8例、支架置入术 11例 ,经右桡动脉完成支架置入术 1例。结果　介入操作全部成功 ,术后即刻桡动脉搏动恢复正常 ,双上肢平均动脉收缩压差降低至 2 4mmHg。未发生严重并发症。 2 0例平均随访 18 5个月 ,除 1例行球囊血管成形术患者复发外 ,其余 19例均良好。结论　经皮球囊血管成形术和支架置入术的效果可靠、操作相对简单和安全 ,可以作为锁骨下动脉狭窄的一线治疗方法。

Interventional management in 20 patients with subclavian artery stenosis: follow-up results

Objective To describe our follow-up results of interventional management in 20 patients with subclavian artery stenosis. Methods This study involved in 20 symptomatic patients with an average age of 63.4 years,a mean stenose severity of 86.2% and a mean systolic arterial pressure difference of 116 mm?Hg between both upper limbs. Percutaneous transluminal angioplasty (PTA) in the first 8 patients and stenting in the last 12 patients were performed via a right femoral or radial artery. Results Both PTA and stenting were successfully archived in all patients with normalization of radial pulses and a mean systolic arterial pressure difference of 24 mm?Hg between both upper limbs. No major complications occurred. In the follow-up for an average of 18.5 months,19 patients were free of adverse events except one with symptom recurrence. Conclusion As effective,simple and safe procedures,PTA and stenting can be used as a first-line treatment modality for the symptomatic patients with subclavian artery stenosis.
