[The effect on higher cortical dysfunction of percutaneous transluminal angioplasty for internal carotid artery
1Department of Neurological Surgery, Wakayama Medical College.
Insights
Percutaneous transluminal angioplasty (PTA) effectively improved higher cortical dysfunction in patients with internal carotid artery (ICA) stenosis. This treatment is beneficial for those experiencing hemodynamic compromise when the artery is successfully dilated.
Area of Science:
- Neurology
- Vascular Surgery
- Interventional Cardiology
Background:
- Internal carotid artery (ICA) stenosis can lead to hemodynamic ischemia, causing higher cortical dysfunction.
- Evaluating treatment options for cognitive impairment resulting from cerebrovascular disease is crucial.
Observation:
- Seven patients (49-71 years old, 5 male, 2 female) with ICA stenosis and higher cortical dysfunction were treated with percutaneous transluminal angioplasty (PTA).
- Neuropsychological tests were administered before and after the PTA procedure.
Findings:
- All seven patients demonstrated improvement in higher cortical dysfunction following PTA.
- Successful dilation of the ICA was a key factor in the observed improvements.
Implications:
- PTA is a viable and effective treatment for higher cortical dysfunction caused by ICA stenosis and hemodynamic compromise.
- This suggests a potential therapeutic strategy for improving cognitive function in select cerebrovascular patients.
Abstract:
Seven patients with internal carotid artery (ICA) stenosis with higher cortical dysfunction due to hemodynamic ischemia were treated by percutaneous transluminal angioplasty (PTA). The patients ranged from 49 to 71 years of age, and included five males and two females. Neuropsychological tests were evaluated before and after PTA. Higher cortical dysfunction improved in all cases after PTA. It is concluded that PTA is effective to improve higher cortical dysfunction in patients who have ICA stenosis associated with hemodynamic compromise, if the ICA is satisfactorily dilated.
