目的:分析锚定区不足的胸主动脉病变中部分覆盖左锁骨下动脉技术的应用价值。方法:回顾性分析54例锚定区不足的胸主动脉病变患者的临床资料,27例患者行部分覆盖左锁骨下动脉技术治疗,27例行全部覆盖左锁骨下动脉技术治疗,对比两组患者的治疗效果及术后并发症情况。结果:两组患者的锚定区长度、双上肢平均收缩压、术后显影通畅人数比例差异有统计学意义(P<0.05),内漏、脑卒中和围手术期死亡发生率差异无统计学意义(P>0.05);14例内漏消失,2例减少,1例内漏无明显变化。12例完全覆盖组患者出现轻度上肢麻木、乏力全晕等症状,部分覆盖组患者未出现以上症状。结论:对于行胸主动脉覆膜支架植入术治疗的锚定区不足的胸主动脉病变患者,在保证锚定区距离的情况下选择部分覆盖左锁骨下动脉治疗的安全性更高,可有效预防急性脑梗塞发生。
OBJECTIVE: To analyze the value of partial coverage of the left subclavian artery in the thoracic aorta with insufficient anchoring area. Methods: The clinical data of 54 cases of thoracic aortic lesions with insufficient anchorage area were retrospectively analyzed. Twenty-seven patients underwent partial treatment of the left subclavian artery and 27 cases were treated with the left subclavian artery. Compared with the two groups The treatment effect and postoperative complications. Results: The length of anchorage zone, the average systolic pressure of both upper extremities and the percentage of postoperative unobstructed patency in the two groups were significantly different (P <0.05). There was no significant difference in the incidence of endoleak, stroke and perioperative mortality between the two groups Significance (P> 0.05); 14 cases of endoleak disappeared, 2 cases decreased, 1 case of endoleak no significant change. Twelve patients in the complete coverage group showed mild upper limb numbness and weakness and full halo, and some of the patients in the covered group did not have the above symptoms. CONCLUSIONS: For patients with thoracic aortic lesions who have undergone stent placement of thoracic aortic stents for the treatment of thoracic aortic lesions, it is safer to choose a partial coverage of the left subclavian artery with a guaranteed distance from the anchorage zone. Effective prevention of acute cerebral infarction.
