Delayed leukoencephalopathy following non-coil embolization flow diverter stent deployment for an intracranial aneurysm. | LitMetric
This report examines delayed leukoencephalopathy as a postoperative complication after the use of flow diverter (FD) devices for endovascular cerebral aneurysm treatment. A case involving a 78-year-old female treated with a pipeline embolization device for a left internal carotid artery aneurysm is presented. Despite adherence to dual anti-platelet therapy, the patient developed intermittent headaches and memory issues 3 months post-operation. MRI revealed T1-enhancing foci and T2 hyperintense signal abnormalities in the left cerebral hemisphere, without new ischemic lesions, indicating potential embolic events or foreign body reactions. Following aphasia, a change from clopidogrel to prasugrel and the initiation of steroid pulse therapy led to the resolution of symptoms and MRI abnormalities over 6 months. This case underscores the reversibility of delayed leukoencephalopathy with appropriate intervention.
