锁骨下动脉狭窄经皮血管腔内成形术及支架植入术的临床研究

目的探讨经皮血管内支架治疗动脉粥样硬化或大动脉炎所致锁骨下动脉狭窄及梗阻性病变的临床疗效。方法9例锁骨下动脉狭窄及梗阻性病变患者中，5例为动脉粥样硬化，4例大动脉炎。其中，锁骨下动脉狭窄2例，完全闭塞7例，均成功的置入血管内支架治疗。结果9例行经皮血管内支架置入治疗的患者均获成功，有5例置入Wallstent支架，4例置入Palmaz支架。术后即刻桡动脉搏动恢复正常，双上肢平均动脉压差降低至2．0kPa，介入治疗后，血管恢复通畅，患者临床症状消失。未发生严重并发症，9例介入治疗成功者随访6～18个月，无1例发生再狭窄。结论血管内支架置入术治疗动脉粥样硬化或大动脉炎所致锁骨下动脉狭窄梗阻性病变，安全、可靠、成功率高、并发症少、临床疗效好，是目前最有效的治疗方法之一，可以作为锁骨下动脉狭窄的一线治疗方法。

Clinical Study on Subclavicular Artery Stenosis Treated with Percutaneous Transluminal Angiography and Stand Implantation

Objective To discuss the clinical curative effect of subclavicular artery stenosis treated with percutaneous transluminal angiography(PCTA) and stand implantation.Methods There 5 cases in arteriosclerosis and 4 cases in arteritis in 9 cases.There were 2 cases stenosis and 7 cases complete occlusion.All had underwent the stand implantation.Results All cases had successfully performed PTCA and stand implantation(5 cases of Wallstent and 4 cases of Palmaz).The radial artery pulse recovery and both upper limbs MAP decreased to 2 Kpa.There was no clinical manifestation without severe complication.All cases had followed up 6～18 months without stenosis.Conclusion The PTCA and SI might be safe,reliable,successful and good effect without complication.It might be first line therapy method for such disease.
