Abstract

The “spectacular shrinking deficit” (SSD) [1–4] refers to a syndrome of profound hemispheric ischemia that resolves rapidly over hours to days leaving patients with minimal residual neurological deficits. It is postulated that the SSD results from rapid clot lysis, fragmentation, and migration along the internal carotid-middle cerebral arterial axis, with tissue perfusion being restored before irreversible damage has occurred. Clot migration has been demonstrated angiographically in this syndrome [4]; however, the tissue perfusion changes have not previously been described.
