Strokes in the subinsular territory: clinical, topographical, and etiological patterns.
The authors studied 11 patients with subinsular stroke (subIS) located in a deep border zone between lenticulostriate arteries and small insular cortical penetrating branches of the middle cerebral artery. The typical clinical features of subIS were motor deficits (11 patients), sensory disturbances (6 patients), transcortical motor aphasia and hypophonia (2 patients), and transient dysphagia at stroke onset (5 patients). Large artery disease and cardioembolic mechanisms may give rise to subIS by hemodynamic mechanisms.
