Temporary Solitaire stent neck remodeling in the coiling of ruptured aneurysms
Bibliographic record
Abstract
BACKGROUND: Stent-assisted coiling is a commonly adopted technique employed in the coiling of broader-based aneurysms. It avoids flow arrest and the risk of vessel rupture associated with balloon-assisted coiling. However, there is a risk of stent thrombosis with the corollary risk of stroke during and after the procedure. Antiplatelet agents are used to mitigate this risk but raise a secondary concern of hemorrhagic complications, particularly with ruptured aneurysm where further interventions such as ventriculostomy occur not infrequently. Stent removal after coil embolization would eliminate the risk of post-procedure stent thromboembolic complications and alleviate the need for continuing antiplatelet therapy. METHODS: A prospectively maintained endovascular database was searched to identify patients who underwent stent-assisted coil embolization followed by stent retrieval and removal. The clinical and technical aspects of the cases were obtained in addition to the procedural outcomes. RESULTS: Three cases were identified where the use of the fully resheathable Solitaire AB Neurovascular Remodeling Device permitted the coiling of broad-based aneurysms with subsequent retrieval and removal of the stent. All patients presented with subarachnoid hemorrhage and received aspirin prior to the procedure. Two patients did not require antiplatelet therapy after the procedure. No coil herniation or thromboembolic events were encountered. CONCLUSIONS: Stent retrieval and removal can be done safely in selected cases at the end of stent-assisted coil embolization using the Solitaire AB device. This technique avoids the need for continuing antiplatelet therapy, which can be particularly important in the setting of acute subarachnoid hemorrhage.

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.
