经眼动脉超选插管溶栓治疗视网膜中央动脉阻塞

目的探讨超选择性眼动脉溶栓治疗视膜中央动脉栓塞治疗方法和疗效。方法采用Seldinger技术，对9例患者经超选择性眼动脉插管，用尿激酶18~75万U直接灌注溶栓治疗。结果其中8例患者视力有不同程度的提高，1例患者视力与治疗前相比没有变化；各例患者在治疗过程中均未出现任何并发症。结论视网膜中央动脉阻塞介入溶栓治疗可使大部分患者视力不同程度的提高。临床疗效与发病时间、尿激酶用量及治疗前视力不呈正相关。超选择性眼动脉溶栓治疗视网膜中央动脉阻塞是安全、可靠的。(中华眼底病杂志,2005,21:22-24)

Treatment of central retinal artery occlusion by thrombolysis via super-selective ophthalmic artery catheterization

Objective To investigate the therapeutic method and effect of thrombolysis via super-selective ophthalmic artery catheterization treating central retinal artery occlusion (CRAO). Methods 9 patients with CRAO were treated by urokinase infusion via super-selective ophthalmic artery catheterization with Seldinger technique. Results In the 9 patients, the visual acuity was improved to different extent in 8, and remained unchanged in 1. No complications was found during the treatment in any patients. Conclusions Thrombolysis via super-selective ophthalmic artery catheterization for CRAO can improve the visual acuity of most of the patients in different degrees. No positive relation exists in clinical therapeutic effect, time of onset, quantity of urokinase and the visual acuity before the treatment. The method of thrombolysis via super-selective ophthalmic artery catheterization for CRVO is safe and reliable.
