[Watershed infarctions--a special type of infarction in cases with carotid artery stenosis or occlusion verified by CT and angiography (author's transl)].
Watershed infarctions appear in the axial CT-sections mostly as stained or striated hypodense areas in the white matter of the parietal and seldom temporal region, without or with extension into the supply area of the adjacent cerebral arteries. We observed these changes in approximately 40% of our series with carotid artery stenosis or occlusion. These findings may be very subtle, and in such cases angiography should be performed.
