鼻泪道支架植入术治疗鼻泪道阻塞

目的：观察鼻泪道支架植入术治疗鼻泪道阻塞的近期及中期疗效,评价其临床应用价值。方法：对102例（136只眼）鼻泪道阻塞患者行鼻泪道支架植入术,经逆行扩张鼻泪道后植入特制的鼻泪道支架,并于手术前后行数字减影泪道造影检查,分析其疗效。结果：136只眼中,成功植入支架132只眼,手术成功率为97．1％。术后随访3个月,有效率为99．2％;1年随访有效率为91．4％。并发症包括支架植入失败、术中活动性出血及术后支架阻塞等。结论：鼻泪道支架植入术不改变局部解剖结构,是一种简单、安全及有效的治疗鼻泪道阻塞的新方法。

Lacrimal duct stent for nasolacrimal duct obstruction

Objective To introduce a new interventional procedure using lacrimal duct stent for the treatment of nasolacrimal duct obstruction, evaluate the short term and long term efficacy and observed its intra and post operative complications and management Methods 102 cases (136 eyes) of nasolacrimal duct obstruction underwent the lacrimal duct stent placement, the nasolacrimal duct was dilated and the stent was placed retrograde Digital subtraction dacryocystography was performed before and after the stent placement Results Stent placement was technically successful in 132 eyes, and the technical success rate was 97 1% Good flow of contrast medium was obtained in all patients after stenting Three months postoperatively, the success rate was 99 2% After twelve months of follow up, the success rate was 91 4% The intra and post operative complications included stenting failure, transient hemorrhage and obstruction of the stent Conclusion Interventional procedure using lacrimal duct stent is a safe, simple and effective method for nasolacrimal duct obstruction without disturbing the normal anatomy
