People require double antiplatelet therapy for a period of up to 3 months after the procedure and aspirin therapy for up to 1 year. In a systematic analysis of 19 studies with 207 cases, there was an 87% improvement in overall symptom rate and 90% cure rate for treatment of papilledema. Major complications only occurred in 3/207 people (1.4%). [23]
