摘要
目的探讨腔内治疗锁骨下动脉盗血综合征(SSS)的临床疗效与安全性。方法 2005年4月—2013年2月对12例SSS患者(锁骨下动脉狭窄7例,闭塞5例)行腔内治疗,其中单纯经皮血管球囊成形术(PTA)4例,支架植入8例(8枚支架)。结果手术成功率为100%(12/12)。患/健侧收缩压比由术前0.46±0.28提高至术后的0.89±0.32,差异有统计学意义(P<0.05)。术后患者临床症状均不同程度改善,随访16.7±7.9个月,1例左侧锁骨下动脉闭塞患者PTA术后13个月再狭窄,给予支架治疗后好转;1例锁骨下动脉重度狭窄患者PTA术后23 d出现患肢末梢微血管栓塞,经改善微循环、扩血管等治疗后好转,无脑卒中等严重并发症发生。结论腔内治疗SSS是微创、安全、有效的治疗方法,能明显改善患者因盗血导致的椎-基底动脉供血不足的临床症状,改善患肢乏力、温度低等症状,值得临床上推广应用。
Objective To investigate the efficacy and safety of endovascular treatment for subclavian steal syndrome (SSS). Methods During the period from April 2004 to Feb. 2013 at authors’ hospital, a total of 12 patients with SSS, including subclavian artery stenosis (n = 7) and occlusion (n = 5), underwent endovascular treatment. Percutaneous transluminal angioplasty (PTA) was carried out in 4 cases and stent implantation in 8 cases. The clinical data were retrospectively analyzed. Results Technical success rate was 100%(12/12). The diseased side/healthy side blood pressure ratio increased from preoperative (0.46 ± 0.28) to postoperative (0.89 ± 0.32), and the difference was statistically significant (P 〈 0.05). After the treatment, the clinical symptoms were improved in different degrees in all patients. During the follow - up period lasting for (16.7 ± 7.9) months, restenosis occurred in one case with left SSS thirteen months after PTA, and the condition was improved after stenting angioplasty. Another patient with severe subclavian artery stenosis developed peripheral micro- vascular thrombosis of the diseased limb in 23 days after PTA, which was relieved after medication to improve microcirculation and vasodilation. No severe complications such as stroke occurred. Conclusion For subclavian artery steal syndrome, endovascular management is a minimally invasive, safe and effective treatment. It can significantly relieve the clinical symptoms due to vertebral- basilar artery insufficiency caused by subclavian steal syndrome, and improve limb weakness, low body temperature, etc. Therefore, this technique should be recommended in clinical practice.
