Personality change after 'flow diverter implantation' for intracranial aneurysm in a patient with stroke: A case report
Brain injury(2023)
Abstract
ObjectiveThis study aimed to present a patient with psychiatric symptoms that occur after flow diverter stent placement in a posterior communicating artery (PComA) aneurysm in a patient.DesignA case study.MethodWe performed cranial magnetic resonance imaging (MRI), magnetic resonance angiography, computed tomography angiography, neuropsychological tests, Levenson Self-Report Psychopathy Scale (LSRP), and a 25-item version of the Wender Utah Rating Scale (WURS-25). The patient's recent MRI was compared with previous MRIs. Neuropsychological testing consisted of a clinical interview, clinical assessment of frontal lobe syndrome, and tests evaluating the prefrontal cortex functions (Wisconsin Card Sorting Test-128 card version and Iowa Gambling Test).ResultsOur results showed that the patient's personality change and psychiatric symptoms occurred after the stent placement. Symptoms were still present at evaluation two and a half years after stent placement.ConclusionThe study demonstrates personality changes and psychiatric symptoms that might occur as complications following the placement of a flow diverter for incidentally detected aneurysm.
