Computed tomography (CT) of the head and a routine 12-lead electrocardiogram (ECG) on admission. CT shows left hyperdense middle cerebral artery sign (arrowhead) (a). Twelve-lead ECG shows ST-segment elevation at II, III, and aVF (b).

Computed tomography (CT) of the head revealed no intracranial hemorrhage but the left hyperdense middle cerebral artery (MCA) sign [Figure 1a]: the Alberta Stroke Program Early CT Score was 10 points. In addition, admission 12-lead electrocardiogram (ECG) showed ST-segment elevation in II, III, and aVF, leading to the diagnosis of CCI [Figure 1b].
Percutaneous coronary intervention (PCI) and mechanical thrombectomy (MT). Coronary angiography shows occluded right coronary artery (a) and thrombolysis in myocardial infarction Grade 3 recanalization after PCI (b). Cerebral angiography shows the left M1 occlusion (c) and thrombolysis in cerebral infarction Grade 2b recanalization after MT (d).

Coronary angiography revealed occlusion of the right coronary artery, which was treated with PCI using a thrombosuction catheter to retrieve a red clot, resulting in thrombolysis in myocardial infarction Grade 3 recanalization [Figures 2a and b]. Subsequently, cerebral angiography was performed to show the left M1 occlusion followed by MT using a stent retriever which retrieved a red clot and accomplished thrombolysis in cerebral infarction Grade 2b recanalization [Figures 2c and d].
Postoperative magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the head. MRI shows the left middle cerebral artery territory cerebral infarction (a). MRA shows almost patent left middle cerebral artery (b).

Postoperative brain magnetic resonance imaging and angiography showed the almost patent left MCA but with extensive left MCA territory infarction [Figures 3a and b].
