Delayed middle cerebral artery occlusion following endovascular coiling of carotid terminus aneurysm
Bibliographic record
Abstract
Endovascular coil embolization of intracranial aneurysms is a relatively safe and effective alternative to traditional clip ligation. While bare platinum coils have long been used with good success, newer bioactive coils have been developed since approximately 2002 in an attempt to improve occlusion rates. Although unexpected complications such as aseptic meningitis , seizures , new-onset headaches , hydrocephalus , cranial nerve palsies and delayed visual compromise have been described following the use of both bare platinum coils and bioactive coils, we have not yet seen reports of delayed large vessel occlusion . We describe an unusual case of an uncomplicated, elective endovascular coil embolization of a right internal carotid artery (ICA) terminus aneurysm using a combination of bare platinum coils and HydroCoils leading to the delayed occlusion of the proximal M1 segment of right middle cerebral artery (MCA) with no clinical sequelae .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
