To present our experience in the treatment of nasolacrimal occlusion by means of polyurethane stents.
Forty polyurethane stents were placed under fluoroscopic guidance in 35 consecutive patients with epiphora due to total or partial obstruction of the nasolacrimal system. The set designed by Song was used in all patients. The procedure was performed by introducing a guidewire through the superior punctum into the canaliculus and advancing it across the obstruction into the inferior meatus of the nasal cavity. After pulling out the guidewire, the stent was advanced in retrograde fashion and released into the sac and the nasolacrimal duct.
The technical success rate was 100%. The average time for the procedure was 25 min (range 10-60 min). Immediate complications were: mild pain (n = 5), severe pain (n = 1), minimal epistaxis (n = 7), and moderate epistaxis (n = 1). No major complications occurred. The last clinical control revealed complete resolution of epiphora in 35 eyes and partial resolution in four; one patient did not improve.
This technique for treatment of obstruction of the nasolacrimal system is simple and safe, and may obviate the use of more invasive procedures.
介绍我们使用聚氨酯支架治疗鼻泪管阻塞的经验。
在透视引导下，为35例因鼻泪系统完全或部分阻塞而溢泪的连续患者置入40个聚氨酯支架。所有患者均使用宋氏设计的套件。该操作通过将导丝经上泪点插入泪小管，并使其穿过阻塞部位进入鼻腔下鼻道来进行。拔出导丝后，将支架逆行推进并释放到泪囊和鼻泪管中。
技术成功率为100%。该操作的平均时间为25分钟（范围10 - 60分钟）。即刻并发症有：轻度疼痛（n = 5）、重度疼痛（n = 1）、少量鼻出血（n = 7）和中度鼻出血（n = 1）。未发生重大并发症。最后一次临床检查显示，35只眼溢泪完全缓解，4只眼部分缓解；1例患者未改善。
这种治疗鼻泪系统阻塞的技术简单且安全，并可能避免使用更具侵入性的手术。
