Left internal carotid artery occlusion and acute-phase cerebral infarction in the left middle cerebral artery region were observed on head magnetic resonance angiography (MRA) and diffusion-weighted imaging (DWI) conducted 30 min after onset, respectively (Fig. 1).
Pre- and postoperative angiography. A: Preoperative left internal carotid angiography demonstrating internal carotid artery occlusion at the level of the origin of the posterior communicating artery. B: Left internal carotid angiography after thrombectomy with the Merci retrieval device, showing complete reperfusion of the internal carotid and middle cerebral arteries.

Left internal carotid artery images showed left internal carotid artery occlusion at the level of the posterior communicating artery bifurcation (Fig. 2A). Left internal carotid artery imaging after thrombus removal showed complete recanalization of the left internal carotid artery, and visualization of the left middle cerebral artery periphery was also satisfactory (Fig. 2B).
Contrast-enhanced computed tomography of the body trunk. A: Contrast-enhanced computed tomography of the chest demonstrating thrombus formation (arrow) in the pulmonary vein stump after left upper lobectomy. B: Contrast-enhanced computed tomography of the abdomen showing acute splenic infarction (arrow).

Contrast-enhanced CT (CECT) of the trunk conducted 7 days after thrombus removal showed thrombus formation in the left upper pulmonary vein stump after left upper pulmonary lobectomy (Fig. 3A). In addition, acute splenic infarction was detected on CECT, and was thought to have developed at the same time as cerebral embolism (Fig. 3B).
