Coil embolization of basilar tip aneurysms: Analysis of complications

Abstract

Although various treatments of cerebral aneurysms continue to be the methods of care, best treatment method is still controversial. Despite recent advances in endovascular techniques, coil herniation and parent artery occlusion may complicate the treatment, particularly in wide-necked aneurysms. Endovascular therapy is an effective alternative for treating basilar artery (BA) bifurcation aneurysms. It is important to select a suitable treatment option in each case depending on the patient's condition and the angiographic features of each aneurysm. In this report, the mechanism of early parent vessel occlusion by coils, and the pathogenesis of thrombosis associated with coil embolization are discussed. Endovascular treatment of cerebral aneurysms is not always safe method but efficacious therapeutic alternative to surgery in selected cases. The purpose of this study was to discuss the indication, limitations and complications of coil embolization for BA bifurcation aneurysms with illustrative Hunt-Hess high grade patient.
