Treatment of primary orbital varix via inferior petrosal sinus approach / 中国脑血管病杂志

ABSTRACT

Objective To investigate the effectiveness of treatment of primary orbital varix via venous embolization therapy approach. Methods From January 2007 to January 2015,the clinical data of 12 patients with primary orbital varix were analyzed retrospectively. All the micro-catheters were implanted via the inferior petrosal sinus approach. The microcoils and Onyx18 were used to embolize the primary orbital varix. Four patients were embolized with micro-coils only, three were embolized with Onyx, and five were embolized with microcoil + Onyx. Results After successful catheterization, the lesions were totally embolized in 12 patients. The symptoms of postural exophthalmos disappeared and the pain was relieved,the depressed symptom of eyeball disappeared in 10 cases, and two patients were relieved partially ( single material embolization) . Nine patients were followed up for 6 to 24 months. The orbital DSA,MRI or CT re-examination was performed. The thrombosis of orbital varices within the lesions was observed and no cavity was found. One of the patients suffered from limited lateral eyeball abduction. Another three were lost to follow up. Conclusion The embolization treatment of primary orbital varix is safe, effective, and convenient via inferior petrosal sinus approach.
