Treatment of Intracranial Venous Occlusive Disease with Sigmoid Sinus Angioplasty and Stent Placement in a Case of Infantile Multifocal Dural Arteriovenous Shunts
Bibliographic record
Abstract
SUMMARY: The infantile dural arteriovenous shunts are multifocal involving different dural sinuses and progress to an occlusive venopathy with sigmoid sinus and/or jugular bulb stenosis and subsequent occlusion. We report a successful angioplasty and stent placement of a sigmoid sinus - jugular bulb stenosis due to venous occlusive disease in a patient with infantile dural arteriovenous shunts. A five-year-old patient presented with status epilepticus due to severe venous congestive encephalopathy. The angiogram revealed multifocal dural arteriovenous shunts, occlusion of the right sigmoid sinus, absence of cavernous sinuses and significant stenosis of the left sigmoid sinus - jugular bulb. By transvenous approach, percutaneous transluminal balloon angioplasty and stent placement of the stenosed left sigmoid sinus - jugular bulb segment was performed. This resulted in a significant decrease of the venous pressure gradient across the stenosis and allowed a dramatic clinical recovery. Dural sinus angioplasty and stent placement appears to be a safe and effective procedure and should be considered in the treatment of the venous occlusive disease associated with infantile dural arteriovenous shunts.

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.
