Endovascular treatment of a patient with traumatic dissection lesions of both vertebral arteries obtained during chiropractic manipulation
Bibliographic record
Abstract
The observation of endovascular treatment of a 34-year-old woman with bilateral dissection lesions of vertebral arteries in V4-segments with occlusion of the right vertebral artery and right posterior inferior cerebellar artery, severe stenosis of the left vertebral artery caused by chiropractic manipulation in the neck region is described. There are intensive staticolocomotor and dynamic coordinating insufficiency, severe neck pain, headache, severe dizziness, Wallenberg syndrome, moderate central tetraparesis. MRI of the brain on the DWI Isotropic identified the hyperintensive round-shaped foci in the right hemisphere of the cerebellum, in the right side of cerebellum worm, in the right side of the medulla oblongata and in the right side of the pons (DWI BSS 3). Selective cerebral angiography was performed an hour after the clinic manifestation. Simultaneously, balloon angioplasty of severe dissection stenosis was performed in the V4-segment of the left vertebral artery by the compliant balloon-catheter Scepter C. In 18 hours from the development of vertebral artery dissection, self-expending stent LVIS was implanted into the left vertebral artery in the zone of dissection lesion. On the control angiograms: the left vertebral artery patency is restored without stenosis all along. The stent is fully opened. A second contrast contour is determined outside the stent in the dissection zone. All the arteries of the vertebrobasilar basin above the vertebrobasilar junction are passable. The V4-segment of the right vertebral artery is contrasted through the vertebrobilar junction. There was a rapid regression of neurological symptoms in the postoperative period. Only mild hypoesthesia on the right side in the outer Sölder’s zone, light coordination disorders on the right were remained. Control selective cerebral angiography revealed recanalization of the right vertebral artery and the right posterior cerebellar artery. But distal basin of the right posterior cerebellar artery is very poorly. The left vertebral artery is passable all over, but in the place of the former dissection, two equivalent arterial «sleeves» were formed according to the fenestration type. One «sleeve» is formed by a stent, the other — outside. All arteries of the vertebrobasilar basin are contrasted. The mild hemihepesthesia on the right side of the face in the outer Sölder’s zone, light coordination disorders on the right are remained. Implantation of the self-expanding stent LVIS allowed to restore the dominant vertebral artery and restrict ischemic brain damage in the brain stem and cerebellum in a patient with a both vertebral arteries dissection lesion caused by chiropractic neck manipulations.

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.
