Functional Outcome And Reebleding Risk In Patients With Ruptured Aneurysm Treated With Flow Diverter

Background: Intracranial aneurysms are abnormal dilatations in cerebral arteries, most often located at arterial bifurcations. They are part of cerebrovascular diseases and have a worldwide prevalence estimated between 5% to 10% in the general population. Methods: Observational, descriptive, analytical, retrospective cohort study, with the aim of determining the functional outcome according to the Rankin scale of patients with ruptured intracranial aneurysms treated with flow diverter at 6 and 12 months post treatment. Results: The population was 37 patients treated with flow diverter of which 12 met the inclusion criteria. The mean age was 43.9 years. 50% of patients were female and 50% of patients were male, with a M:H ratio of 1:1. 66.7% were ruptured aneurysms of infratentorial location treated with flow diversion, of which the basilar artery and vertebral artery were the most prevalent arterial segments with 33.3% respectively. Conclusion: The use of flow diversion in patients with ruptured intracranial aneurysms is associated with excellent functional results (Rankin<1) in the medium and long term. In addition, the use of flow diversion devices showed occlusion rates at 6 months and aneurysmal exclusion in 100% of patients at 12 months.
