RÉSUMÉ
Objective To investigate the safety,efficacy and feasibility of endovascular recanalization in non-acute symptomatic occlusion of the ophthalmic segment of internal carotid artery,and analyze the factors affecting its success.Methods Fifty-four patients with non-acute symptomatic occlusion of the ophthalmic segment of internal carotid artery,underwent endovascular recanalization in our hospital from January 2013 to December 2017,were enrolled.Modified Rankin scale (mRS) and National institutes of health stroke scale (NIHSS) scores were compared before and after treatment;the prognosis results were analyzed after 2 years of follow-up.Independent factors influencing the prognoses were identified by Logistic regression analysis.Results Recanalization was achieved in 52 patients and failure was noted in two patients.The mRS scores and NIHSS scores before treatment (2.25±0.13,18.43±1.36) were significantly higher than those after treatment (1.44±0.05,11.81±0.71,P＜0.05).After 2 years of follow-up,good prognosis was noted in 42 patients,poor prognosis in 8 patients,and loss of follow-up in 2 patients.Multivariate Logistic analysis showed that history of hypertension and history of diabetes were independent risk factors for the prognoses of patients with non-acute symptomatic occlusion of the ophthalmic segment of internal carotid artery after endovascular reeanalization (OR=1.429,95CI:1.146-1.783,P=0.005;OR=2.597,95CI:2.364-2.854,P=0.005).Conclusion The curative effect of interventional therapy for non-acute occlusion of symptomatic internal carotid artery is reliable,and histories of hypertension and diabetes can affect the prognoses of patients.
