Novel aneurysm neck reconstruction device: initial experience in an experimental preclinical bifurcation aneurysm model.
BACKGROUND
Treatment of wide-necked bifurcation aneurysms often poses procedural and long-term outcome challenges. The initial preclinical experience with the Pulsar Vascular Aneurysm Neck Reconstruction Device (PVANRD) in a canine bifurcation model is described.


METHODS
Experimental bifurcation vein pouch aneurysms were surgically created in the carotid arteries of eight dogs. Endovascular coiling of the aneurysms with assistance of the PVANRD was performed in all cases with acute performance compared with Y-stenting.


RESULTS
Twelve devices were deployed in the eight cases. Deployment of the devices was straightforward and successfully protected the parent artery and maintained patency of the bifurcation in all cases, despite the use of oversized coils.


CONCLUSIONS
The PVANRD is a novel bifurcation stent that facilitates treatment of wide-necked bifurcation aneurysms compared with currently available adjunctive devices.
