手术治疗锁骨下动脉闭塞症

目的探讨锁骨下动脉闭塞症的有效手术治疗方法。方法 2005年12月-2010年2月,收治锁骨下动脉闭塞症53例。男40例,女13例;年龄22～77岁,平均64岁。病程15d～20个月,平均6.5个月。动脉硬化闭塞症49例,大动脉炎4例。左锁骨下动脉闭塞35例,狭窄5例;右锁骨下动脉闭塞5例,狭窄4例;双侧锁骨下动脉闭塞4例。对39例单侧锁骨下动脉闭塞伴颈、脑动脉病变者采用腋动脉-腋动脉聚四氟乙烯(polytetra?uoroethylene,PTFE)人工血管转流术;10例不伴颈、脑动脉病变者行颈动脉-锁骨下动脉PTFE人工血管转流术。4例双侧锁骨下动脉闭塞者采用升主动脉-双锁骨下动脉PTFE人工血管转流术。术后常规应用抗凝及抗血小板药物治疗。结果 1例大动脉炎患者术后48h动脉吻合口及人工血管血栓形成;余52例手术均获成功,手术成功率98.11%。术中神经钳夹损伤2例,术后双侧吻合口周围血肿4例,均经保守治疗痊愈。52例手术成功患者均获随访,随访时间1～52个月,平均24.5个月。患者均存活,术前椎基底动脉及上肢动脉缺血症状均消失。彩色超声多普勒血流探测仪检查见吻合口及人工血管血流通畅,术后1年及2年人工血管通畅率均为100%;患侧椎动脉血流方向恢复正常。1例术后18个月出现腋动脉吻合口假性动脉瘤,行介入栓塞治愈。结论锁骨下动脉闭塞症的治疗术式较多,但应根据患者全身情况和病变特点进行合理选择。围手术期的正确处理及术中严格操作,是保证手术成功的关键。

Surgical treatment of subclavian artery occlusion

Objective To explore the effective surgical approaches in treating subclavian artery occlusion. Methods Between December 2005 and February 2010, 53 patients with subclavian artery occlusion were treated, including left subclavian artery occlusion (35 cases) and stenosis (5 cases), right subclavian artery occlusion (5 cases) and stenosis (4 cases), and bilateral subclavian artery occlusion (4 cases). There were 40 males and 13 females with an average age of 64 years (range, 22-77 years), including 49 cases o...
