Embolization of a wide-necked basilar bifurcation aneurysm by double-balloon remodeling using HyperForm compliant balloon catheters.

摘要

We report a patient with a wide-necked basilar bifurcation aneurysm that was difficult to address by standard coil embolization because the left and right posterior cerebral artery (PCA) branched from the base of the aneurysm. To preserve both PCAs, the aneurysm was endovascularly embolized using a double-balloon remodeling technique and HyperForm compliant balloon catheters (MicroTherapeutics, Irvine, CA, USA). The aneurysmal neck was not tightly embolized to avoid coil protrusion into the parent arteries. The present technique is an important adjunct to the embolization of wide-necked basilar bifurcation aneurysms.
