Abstract： Objective To evaluate the safety and efficiency of Solitaire? AB neurovascular remodeling device - assisted coil embolization for patients with wide - necked or complex aneurysms. Method From August 2010 to December 2010, the consecutive data were collected from 20 patients with aneurysms treated with comined stenting. All patients underwent clinical and angiographic follow - up after the initial treatment. Results Successful position of the remodeling device was obtained in all cases. There were three complications ( 15% ), and only one complication (5% ) was attributed to the application of stent. One of the three patients was dead for hydrocephalus caused by cerebral hemorrhage during AVM embolization. One thromboembolic complication occurred after the stent was deployed. One ophthalmic artery occlusion occurred after coiling. The proportion of patients in whom Raymond class 1 occlusion was obtained was 65% ( n = 13). Raymond class 2 occlusion was achieved in 10% ( n = 2) and Raymond class 3 occlusion in 25% ( n =5). Nineteen patients left the hospital with a good clinical status. Conclusions The initial technical and clinical results of Solitaire? AB device - assisted coiling of aneurysm are encouraging. But we suggest that it may be applied in the vessel which diameter is more than 2 mm. In addition,the long - term outcome of patients and experiences of using this device need further study.
