Carotid artery occlusion secondary to retropharyngeal abscess treated with endovascular carotid sacrifice
Bibliographic record
Abstract
Introduction: Carotid occlusion is a rare but serious complication of retropharyngeal abscess (RPA). Management questions that must be addressed include the choice between reconstruction and occlusion in the setting of an active infectious process. Case Report: A 4 year old female presented with hoarseness, shortness of breath, and a right-sided Horner’s syndrome. A CT scan confirmed the diagnosis of RPA, and contrast studies showed no filling in the right internal carotid artery (ICA). Surgical exploration of the abscess disrupted the occluded artery, causing deep, uncontrolled bleeding. Emergent angiographic evaluation was completed, and the decision was made to sacrifice the ICA. The patient recovered on antibiotics, but the Horner’s syndrome persisted. Discussion: The presence of a carotid artery occlusion must be ruled out in the setting of a RPA. When suspected, it should be investigated further. Therapeutic decisions regarding sacrifice or reconstruction of the carotid artery are burdened by risks associated with the setting of an infection, notably infection and systemic dissemination. Conclusion: The presence of a carotid occlusion is a serious complication resulting from a RPA that can lead to permanent neurological deficit. Endovascular vessel sacrifice is a viable treatment option for carotid occlusion in the setting of a retropharyngeal abscess, but must be considered on a case-by-case basis.

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.
