Successful throb endarterectomy in a patient with occlusion of the internal carotid artery
Bibliographic record
Abstract
Strokes account for 15–25 % of confirmed cases internal carotid artery (ICA) occlusion. The frequency of ICA occlusion in asymptomatic patients is unknown. The strategy of treatment patients with symptomatic ICA occlusion has not been determined. A clinical observation is presented with the stage of surgical treatment of a 67‑year-old patient with a developed stroke in the basin of the left middle cerebral artery. The examination according to MSCT angiography revealed occlusion of the left ICA. To assess the brain perfusion, a single-photon emission computed tomography (SPECT) with 99mTc was performed. Throb endarterectomy of the left internal carotid artery was performed, with a control ultrasound examination on the 6th day after the operation and after 6 months the blood flow through the internal carotid artery was preserved. Control SPECT with 99mTc was performed, in comparison with the previous study, a significant improvement perfusion on both hemispheres is determined. Improvements in the neurological status were noted in the form of a complete regression of neurological symptoms. On the sixth day after surgical treatment, the patient was discharged in a satisfactory condition. During the hospital stay, the patient was “examined” using a questionnaire for assessing the quality of life – The Short Form‑36 (SF‑36) and MoCA (Montreal Cognitive Impairment Assessment Scale). The survey was conducted on the 15th day of inpatient treatment, before surgery, and on the 6th day after surgery. After 6 months, the patient was re-interviewed. The results obtained indicate a correlation between the improvement of brain perfusion and cognitive impairment, as well as a positive effect of revascularization of the internal carotid artery on the patient’s quality of life. The presented results indicate not only the possibility, but also the high efficiency of surgical treatment of occlusive lesions of the internal carotid artery. Surgical treatment in the early stages after occlusion against the background of the collapse of atherosclerotic plaque and thrombosis of the lumen is a determining factor in the successful restoration of blood flow, improvement of brain perfusion.

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.
