The "pipe-anchor" technique: A method for intra-aneurysmal loop reduction using a partially unsheathed pipeline stent.

Anchoring for loop reduction was previously described using a non-flow diverter stents or balloon requiring additional devices and exchange maneuvers to deploy a pipeline. The "pipe anchor" technique describes the use of a partially deployed flow diverter system as an anchor. This report suggests that pipeline radial force, albeit low, is sufficient. We believe that this method is worthy of consideration in select cases as a first choice and can be valuable tool in the armamentarium of the endovascular neurosurgeon.
