Perforator infarction immediately distal to the stenosis of parental artery: is it hemodynamic?
1Department of Neurology, Asan Medical Center, Seoul, Korea.
Abstract:
Perforator infarction accompanying intracranial atherosclerosis is usually explained by the obstruction of perforator by atheroma of the parent artery. However, the improvement of neurologic symptom after stenting is hardly explained by the concept. Here, we report a case of perforator infarction caused by the unique hemodynamic condition of the poststenotic area without any plaque at the origin of perforator, which was confirmed by high-resolution magnetic resonance image. Poststenotic area with eddying flow separating the region from the main flow may hemodynamically contribute to the perforator infarction and neurologic symptom.
