【摘要】：目的 探讨鼻泪管支架植入术后泪道再阻塞原因。 方法 对70例(70只眼)鼻泪管支架植入术后再溢泪的泪道阻塞患者进行数字减影泪道造影,并分析其图像。 结果 数字减影泪道造影能清楚地显示鼻泪管支架植入术后再溢泪患者的泪道情况及支架的位置,在数字减影泪道造影技术图片上发现术后再溢泪是支架本身阻塞与其它原因引起,其中支架本身阻塞占45.71%；支架以外的阻塞占54.29%：其中泪小管阻塞占2.86%；泪总管阻塞占5.71%；支架位置异常占45.71%。 结论 鼻泪管支架术后泪道再阻塞的原因一是支架本身阻塞,二是支架以外的阻塞,包括泪小管、泪总管的阻塞及支架位置异常。
[Abstract]:Purpose. To investigate the causes of lacrimal duct re-obstruction after nasolacrimal duct stent implantation. Method. Digital subtraction lacrimal passage angiography was performed in 70 patients with lacrimal duct obstruction after nasolacrimal duct stent implantation. Results. Digital subtraction lacrimal passage angiography can clearly show the lacrimal passage situation and the position of the stent in patients with recurrent lacrimal tear after nasolacrimal duct stent implantation. Among them, the obstruction of stent itself was 45.71%; that of non-stent obstruction was 54.29; of which, the obstruction of lacrimal canaliculus was 2.86; the common lacrimal duct was 5.71; the abnormal position of stent was 45.71. Conclusion. The reason of lacrimal duct re-obstruction after nasolacrimal duct stenting was that the stent itself was blocked and the obstruction outside the stent, including lacrimal tubules, common lacrimal duct obstruction and abnormal stent position.
