title: Unilateral a(1) and m(1) occlusions in a child with trisomy 21.
abstract: We report a child with known trisomy 21 who presented with a stroke. Angiographic evaluation demonstrated unilateral intracerebral arterial occlusions of the A1 and M1 segments of the anterior and middle cerebral arteries. The hypothesis of segmental arterial vulnerability is reviewed in an attempt to explain these findings.
