Trfx indicates year chronic transfusions were begun; MRA, MRA and MRI done; CT, computed tomography; MR, only MRI done; CA, cerebral angiogram; S, infarct; NMV, no moyamoya with vessel changes; MM, moyamoya; NMNL, no moyamoya, no vessel changes; F/U MRA, MRAs done after initial MRA/CA; F/U MRA scan diagnosis, the year of earliest progressive large vessel changes. If the vessels were static, this column lists the initial MRA diagnosis; Prog, progression of large vessel changes; +, progression; −, no progression; latest MRA scan diagnosis, all large vessel changes noted on the most recent MRA; ACA, anterior cerebral artery; L, left; MCA, middle cerebral artery; B, bilateral; ICA, internal carotid artery; PCA, posterior cerebral artery; R, right.
Noncompliant with chronic transfusions.
Had MRA studies prior to initial stroke as part of enrollment in the STOP study.
