This study evaluated patients' preoperative platelet function and the relation between acute embolic or hemorrhagic complications in unruptured intracranial aneurysm patients undergoing stent treatment. From September 2013 to December 2013 we prospectively collected clinical data in all unruptured intracranial aneurysm patients undergoing stent-assisted coiling. All patients received a dual antiplatelet therapy (aspirin and clopidogrel) protocol. ⋯ Anterior circulation aneurysms were also associated with ischemic events (P = 0.034). Silent acute embolism may be frequent in unruptured intracranial aneurysm treated with stent-assisted coiling even when dual antiplatelet therapy is given. The antiplatelet inhibition parameter (MAADP) was a predictor for acute thromboembolism in unruptured intracranial aneurysm patients treated by stent-assisted coiling.
