FIG 1. Endovascular fibrinolysis of the left ICA embolism.
A, Anteroposterior-view angiogram of the left carotid artery reveals occlusion of the left ICA at the cisternal portion.
B, Lateral-view angiogram of the left carotid artery reveals occlusion of the left ICA at the cisternal portion.
C, A microcatheter was advanced into the embolus, and the distal lumen was visualized. This lumen later proved to be a saccular aneurysm. Note that the tip of the microcatheter is on the aneurysmal wall (arrow).
D, Anteroposterior-view angiogram of the left carotid artery after recanalization of the carotid embolism.
E, Left anterior oblique–view angiogram of the left carotid artery after recanalization of the carotid embolism.
