Abstract

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.
