Understanding the regional anatomy is intensively concerned to avoid procedure complications. The purpose of this study is to describe the anatomic relationships of PSV to its adjacent structures using computed tomographic coronary angiograms (CTCA).展开更多

Methods A 48-year-old female presented with right conjunctival chemosis and right abducens nerve paresis. Cerebral angiography demonstrated a right carotid-cavernous sinus fistula associated with persistent primitive trigeminal artery. Transvenous routes to the sinus were failed due to the tortuous facial vein. The fistula was treated by Matrix detachable coils and Fibered detachable coils through the transarterial approach. Results The patient was successfully treated by means of transarterial embolization, and symptoms improved within a week. Conclusions Although other techniques using a transvenous approach may also be useful, transarterial embolization with detachable coils should be a safe and effective method to immediately occlude the fistula.展开更多

The rationale is to prevent re-diversion of flow into the ophthalmic veins and cortical veins in a subtotally occluded carotid cavernous fistula.Method From 1997 to 2004, a total of 46 patients with carotid cavernous fistula were treated by transvenous embolization using the proposed selective occlusion strategy. There were 6 direct and 40 dural cartoid cavernous fistulae. The embolic agents were Guglielmi detachable coils and fibered platinum coils. Transvenous embolization routes included inferior petrosal sinus (IPS) alone (32 patients), IPS and intercavernous sinus (9 patients), and superior ophthalmic vein (5 patients).Result The follow-up period ranged from 4 months to 7 years. One patient developed retinal hemorrhage due to ophthalic vein thrombosis one week after the embolization procedure. Two patients had transient ophthalmoplegia and 2 patients had symptomatic recurrence of the carotid cavernous fistula during the follow-up. Clinical cure was achieved in 44 patients (96%).Conclusion The sequential occlusion strategy offers a safe and effective method in the transvenous embolization of carotid cavernous fistula.展开更多
