鼻泪管阻塞的内涵管治疗

Nasolacrimal duct obstruction treated with plastic stent

目的介绍鼻泪管阻塞的内涵管治疗。方法对9例11只鼻泪管阻塞（鼻泪管与泪囊连接处）置放Song601型内涵管治疗，按Song方法顺行引入导丝，逆行放入内涵管。术前与术后做泪囊造影。结果所有鼻泪管在术后造影均通畅，最长随访日为377天，放内涵管前，所有病例均有Ⅳ～Ⅴ度流泪程度，放内涵管后半年内，10只（91％）流泪明显好转，其中7只完全正常；1只5个月后无效，取出内涵管重新置放，症状消失至今3个月。结论介入治疗界泪管阻塞是一种安全、简单及有效的方法，不影响局部解剖结构。

Purpose To introduce the interventional procedure in the treatment of nasolacrimal duct obstruction. Methods Eleven plastic stems were placed under fluoroscopic guidance in 9 patients with epiphora due to complete obstruction at the junction between nasolacrimal duct and lacrimal sac. The stent we used was Song naso lacrimal duct stent set. According Soang's method. The guidee wire was inserted antegradly and the stent was placed retrogradly. Dacryocystography was performed before and after the interventional procedure. Redults Good flow of contrast medium was obtained in all patients after stenting. The longest follow-up pened s 377 days. Before stent placement, all patients had grade 4-5 epiphora. After stent placement, epiphora resolved completely in 7eyes,partly resolved in 3 eyes and one occluded again in five months which resolved completely after restenting.Conclusion Interventional procedure using stent is a safe, simple, and effective method for nasolacrimal duct obstruction without disturbing the normal anatomy.
