Angiography of Cervical Carotid Plaque Rupture Due to Percutaneus Transluminal Balloon Arterioplasty.

We describe the rare imaging of a plaque rupture at cervical internal carotid artery stenosis after balloon arterioplasty. The patient was an 82-year-old male who complained of left hemiparesis. Diffusion-weighted magnetic resonance imaging revealed multiple high-signal intensity in the right cerebral hemisphere. Magnetic resonance angiography showed severe stenosis at the cervical internal carotid artery. We considered the high risk of hyperperfusion syndrome after revascularization. We planned staged angioplasty. Angiography after arterioplasty revealed a meshlike appearance, like a net, in the arterial wall, which indicated the critical sign of ischemic complications.
