Insights from parent vessels' responses to flow diverters: Key lessons and clinical implications

Cerebrovascular/304B
Flow diverters (FDs) are well-established in the endovascular treatment of cerebral aneurysms, achieving approximately 70% obliteration at 6 months and 83% at 12 months. Despite their efficacy, the higher metal content and resultant hemodynamic alterations induced by FDs may provoke varied unfaborable responses in the parent artery and adjacent jailed vessels. For example, intimal hyperplasia was obserteved inside the flow diverters in up to 42.5%. In addition, among the arterial branches jailed by the flow diverters, brach stenosis or occlusion was observed in 75% of anterior cerebral arteries, 11.8% of anterior choroidal arteries, 58.6% of posterior communicating arteries and 8.1% of ophthalmic arteries. These parent and jailed vessels' responses to flow diverters cannot be overlooked, and will become a clinical issue if left unnoticed. In this presentation, we are going to address this issue, and highlight how this issue will determine our treatment strategy.
