Intra-arterial Tissue Plasminogen Activator for Thrombosis Complicating Cerebral Angiography in a 17-Year-Old Girl
Bibliographic record
Abstract
Few reports describe the use of intraarterial recombinant tissue plasminogen activator to treat intracranial thrombosis in children. A 17-year-old girl with a history of prior venous thrombosis developed a left middle cerebral artery thrombus during diagnostic cerebral angiogram. Therapy with intra-arterial tissue plasminogen activator was initiated. An immediate follow-up angiogram demonstrated recanalization, and diffusion-weighted magnetic resonance imaging 9 hours later showed no evidence of infarction. Following the angiogram, femoral artery thrombosis developed. Treatment with supratherapeutic levels of heparin, localized delivery of intra-arterial tissue plasminogen activator, embolectomy, danaparoid, and dipyridamole failed to re-establish perfusion to the lower leg, and below the knee amputation was required. Neurologic examination remained normal 1 year later. Cerebral damage was avoided with the use of emergency intra-arterial tissue plasminogen activator for cerebral artery thrombosis in this child.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
