Coil embolization of giant serpentine aneurysms: report of two cases arising from the posterior cerebral artery

Abstract

The authors describe the presentation, investigation and successful treatment of two giant serpentine aneurysms with Guglielmi detachable coils. Both aneurysms selectively involved the P2 segment of the posterior cerebral artery. The authors describe an endovascular approach to these challenging lesions as an alternative/adjunct to conventional surgery.
