Intra-DIC (distal intracranial catheter) deployment of the Pipeline embolization device: a novel rescue strategy for failed device expansion.

When a partially deployed PED remains constrained despite exhaustion of standard maneuvers to facilitate opening, the technique of intra-Navien PED deployment is a valuable rescue strategy. This new alternative method of PED deployment can be used to open a stretched device with successful completion of the PED implantation.
