Introduction Treatment of wide necked bifurcation aneurysms often poses procedural and long-term outcome challenges. We describe the initial preclinical experience with the Pulsar Vascular Aneurysm Neck Reconstruction Device (PVANRD) in a canine bifurcation model.
Methods Experimental bifurcation vein pouch aneurysms were surgically created in the carotid arteries of eight canines. Endovascular coiling of the aneurysms with assistance of the PVANRD was performed in all cases with acute performance compared to Y-stenting.
Results 12 devices were deployed in the eight cases. Device deployment was straightforward and successfully protected the parent artery and maintained patency of the bifurcation in all cases, despite the use of oversized coils.
Conclusion The PVANRD is a novel bifurcation stent that facilitates treatment of wide necked bifurcation aneurysms compared with currently available adjunctive devices.
