鼻泪管支架植入术前数字减影泪道造影的意义

应用数字减影泪道造影对 10 7例鼻泪管支架植入的泪道阻塞患者进行检查。结果发现泪总管阻塞患者9只眼 ;阻塞部位在泪囊颈部以上的 12只眼 ,以下的 86只眼。阻塞部位在泪囊水平的患者能进行鼻泪管支架植入 ,术后泪道能保持通畅 ,溢泪症状有所改善。提示鼻泪管支架植入前行数字减影泪道造影有助于鼻泪管支架植入适应证的选择及疗效的评估。

Significance of preoperative digital subtraction dacryocystography for nasolacrimal stent

Digital subtraction dacryocystography were performed prior to placement of a nasolacrimal stent. Among the 107 eyes, the sites of obstruction were in the common canaliculus in 9 eyes, above the neck of the lacrimal sac in 12 eyes and under the neck of the lacrimal sac in 86 eyes. The placement of a nasolacrimal stent may become the treatment of choice for epiphora due to obstruction of the nasolacrimal duct at the saccular or subsaccular level. After operation, these nasolacrimal ducts after stenting were patent and epiphora was resolved completely or partially. The results suggest that the preoperative digital subtraction dacryocystography is helpful in selective indication of placement of a nasolacrimal stent and prognostic assessment of the postoperative outcome.
