目的观察植入特制支架治疗鼻泪管阻塞的疗效。方法在X线监视下共植入特制支架48个,治疗因鼻泪管阻塞而引起溢泪症状病人44例。首先将导丝经泪小点、泪小管、泪囊,通过阻塞的鼻泪管到达下鼻道,钩出导丝后将特制支架逆行植入,头端达泪囊位置时自动扩大成球状。结果48个支架均成功植入,未出现严重并发症。38只眼溢泪症状完全消失,4只症状较前有改善,总有效率87.5%,另6个支架出现阻塞或脱出。结论鼻泪管支架植入术是一种简单、安全、有效、损伤小的治疗鼻泪管阻塞的好方法。
Objective To observe the effect of specially stenting on nasolacrimal duct obstruction. Methods A total of 48 special stents were implanted under X-ray monitoring, and 44 cases of patients with overflowing tears due to nasolacrimal duct obstruction were treated. The first guide wire through the tear dot, lacrimal duct, lacrimal sac, nasolacrimal duct through the obstruction to reach the lower nasal passages, the guide wire hook after the retrograde implantation of special stents, head up to the position of the lacrimal sac automatically expanded into a ball. Results All the 48 stents were successfully implanted without serious complications. Thirty-eight eyes had complete disappearance of symptoms of spilled tears, and the four symptoms improved compared with the former. The total effective rate was 87.5%. The other six scaffolds showed obstruction or prolapse. Conclusion Nasolacrimal duct stenting is a simple, safe, effective and less invasive method for the treatment of nasolacrimal duct obstruction.
