The Pipeline Embolization Device (PED) is a flow diverter designed to treat intracranial aneurysms through endoluminal parent vessel reconstruction. The role of adjunctive coil embolization is unknown. ⋯ Flow diversion is an evolutionary step in the treatment of giant intracranial aneurysms. However, complete aneurysm occlusion occurs over a delayed period. The authors recommend placement of coils in addition to PED in the treatment of large or giant distal intracranial aneurysms in an attempt to protect the dome. However, robust packing is to be avoided because it can lead to acute PED thrombotic or compressive occlusion.
