| Outline of Final Research Achievements |
Fifteen cases with ruptured vertebral artery dissection admitted to our institution between 2014 and 2016. All the cases were examined by cerebral angiography, and the anatomical morphological features of the dissected segment were analyzed. Furthermore, computational fluid dynamics (CFD) of the dissected segment was assessed, based on the data obtained from cerebral angiography. We studied the appropriate condition to preserve the perforators arising from the dissected segment using the CFD technique. We created the new design of stent in the computer simulation, however, these stents did not apply to the real clinical situation, because there were too many morphological and anatomical variations of the dissected segment.
