Surgical management of intracranial aneurysms previously treated with endovascular therapy

Endovascular treatment with coils of cerebral aneurysm is being increasingly used for definitive treatment. An increasing number of patients are coming for surgical intervention either for recurrences, incomplete coil embolization or its complications. Our objective was to assess the surgical management in such patients. This was a retrospective analysis of the patients who were initially treated with endovascular embolization and later managed surgically with clipping either for unsuccessful coiling, recurrence of aneurysm or post-procedural complication, between 2003 and 2007. Anatomical results were excellent in all five patients, and all the aneurysms were totally excluded from the circulation. All patients had good recovery. None of the patients suffered any major intraoperative or postoperative complication. Neurosurgical management of intracranial aneurysms previously treated with endovascular therapy is an emerging challenge, but with proper patient selection and careful planning, this subset of aneurysms can be managed with good results.
