title: Spontaneous Early Recanalization after Acute Innominate Artery Thromboembolic Occlusion Secondary to Abrupt Aspirin and Statin Discontinuation: A Case Report.
abstract: Statin and antiplatelet drugs are widely used for prevention of ischaemic stroke and other cardiovascular diseases in high-risk patients. We report a rare case of a 49-year old man with a history of myocardial infarction and hyperlipidaemia who suffered an acute occlusion of his innominate artery (IA) accompanied by subclavian steal syndrome and cerebral infarction, on day seven after abrupt cessation of aspirin and statin, as confirmed by magnetic resonance and computed tomographic angiography of head and neck, and colour-coded Duplex ultrasonography (CCDU). Aspirin and atorvastatin were immediately re-started on admission. Spontaneous recanalization of IA was shown on repeat CCDU and digital subtraction angiography on day 10 after stroke onset. This case serves as a reminder that abrupt discontinuation of both aspirin and statin in patients with previous history of cardiovascular disease may increase the risk of ischaemic stroke.
