Coil embolization of anterior circulation aneurysms supported by the Solitaire AB Neurovascular Remodeling Device

Neuroradiology. 2010 May;52(5):349-59. doi: 10.1007/s00234-009-0568-x. Epub 2009 Jul 31.


Introduction: The purpose of the study is to evaluate patients with wide-necked or complex aneurysms of the anterior circulation who underwent Solitaire AB Neurovascular Remodeling Device-assisted coil embolization.

Methods: From February 2008 to March 2009, consecutive data were collected from 45 patients with anterior circulation aneurysms. Eighteen of the patients presented with acute subarachnoid hemorrhage. Forty-six aneurysms were treated with the aid of different applications (n = 49) of the Solitaire AB Remodeling Device followed by standard coiling procedure (n = 43) using bioactive coils or/and bare coils.

Results: Successful positioning of the remodeling device was obtained in 95.9% of the cases. There were two thromboembolic complications (4.1%) and one severe vasospasm requiring retrieval of the device. Permanent procedural morbidity was observed in one patient (2%). The proportion of patients in whom Raymond class 1 occlusion was obtained was 53.5% (n = 23). Raymond class 2 occlusion was achieved in 42% (n = 18) and Raymond class 3 occlusion in 4.7% (n = 2). Thirty-nine patients left the hospital with a good clinical status.

Conclusion: The initial technical and clinical results of Solitaire AB device-assisted coiling of aneurysms in the anterior circulation are highly encouraging. This technique may enhance the possibilities of the endovascular treatment of these aneurysms in clinical routine.
