Abstract:

【Abstract】 Objective To obtain the preliminary experience on retractable self-expandable stent (LEO) combined with coils for embolization of wide-necked anterior communicating artery aneurysms. Methods Ten wide-necked anterior communicating artery aneurysms were embolized with LEO stent in combination with detachable coils. Six cases were male, and four cases were female. All patients were from 19 to 78 years old, with mean age was 58±6 years old. Six cases were treated by staged release of the LEO stent. Stent delivery cross the aneurismal neck after endovascular coiling of aneurysms was performed in two cases. In another two cases, aneurysms were coiled endovascularly after LEO stent released. The delivery system was advanced inside the Vasco+ microcatheter. The LEO stent was sent back and forth until it was precisely across the neck of the aneurysm. Results Nine aneurysms were embolized completely with stent-coil technique, and one case was partially occluded . There was a thrombo-embolic event following the deployment of the LEO stent in one patient with acute subarachnoid hemorrhage, whom was cured without complications. Conclusion The LEO stent can be deployed accurately within the cerebral vascular vessels. It is a feasible, secure and effective system in treating wide-necked anterior communicating artery aneurysm. Furthermore, its combination with coiling embolization offers a promising therapeutic alternative in the treatment of wide-necked anterior communicating artery aneurysms.
