“…3) In our patient, therapy is not considered very effective. Anticoagulant therapy is reported by Kawano et al 3) to be effective, but recurrence was observed in 3 of the 11 patients administered heparin, and sufficient management of anticoagulation is necessary. Reports regarding endovascular treatment are few, and it should be performed in patients who have suffered recurrence even by anticoagulant therapy.…”

“…This condition, called vertebral artery stump syndrome, has been reported to be likely to recur and have a poor functional prognosis. [1][2][3] Occlusion at the origin of the vertebral artery is considered to be caused by disorders including atherosclerosis, aortitis syndrome, vertebral artery dissection, and trauma. [4][5][6] While it is most often caused by atherosclerosis, radiation-induced cases have also been reported.…”

Objective:We report endovascular treatment of a patient with acute basilar artery occlusion considered to be due to an embolus from radiation-induced vertebral artery stenosis.Case Presentation: The patient was a 46-year-old male with a history of neck irradiation. He developed basilar artery occlusion. Temporary recanalization achieved by intravenous alteplase therapy and revascularization was followed by relapse. The origin of the vertebral artery was stenosed, and basilar artery was considered to have been embolized by a thrombus formed on the proximal side of the vertebral artery, where blood flow was stagnated due to reduced antegrade flow from the distal side of the stenotic vertebral artery and the increased collateral flow from the deep cervical artery.Recurrence of cerebellar infarction could be prevented by revascularization and occlusion of the parent artery. Conclusion:Acute basilar artery occlusion considered to be due to an embolus from radiation-induced vertebral artery stenosis is a rare condition, but it must be recognized as a possible cause of posterior circulation infarction.

“…However, if infarction recurs in the posterior circulation territory alone, angiogenic embolism due to atheroma or stenosis/occlusion of the origin of the vertebrobasilar system and arterial dissection is possible as differential diagnosis. [14][15][16] Particularly, embolism from stenosis/occlusion of the VA origin is attracting attention as VA stump syndrome. 16) Regular search for the source of emboli is carried out, but it is often impossible to identify the cause.…”

Objective: A condition that presents with recurrent embolism due to "hidden bow hunter's syndrome," a subtype of bow hunter's syndrome with a different pathogenic mechanism, is reported. Case Presentation:The patient was a 78-year-old male who exhibited recurrent embolic stroke of the posterior circulation territory resistant to medical treatment. DSA showed occlusion of the right vertebral artery (VA), but dynamic left vertebral arteriography (VAG) presented no change in blood flow. Since indirect signs of occlusion and recanalization of the right VA were retrospectively obtained, dynamic right VAG was performed again on another day, which revealed that the occluded right VA in the neutral neck position recanalized when the neck was rotated to the left. Suspecting that thrombi formed during occlusion scattered with recanalization, we performed embolization of the parent artery in the distal right VA for the prevention of recurrence. Conclusion:This pathological condition should be considered as a differential diagnosis if unexplained ischemia of the posterior circulation is accompanied by unilateral VA occlusion.Keywords▶ bow hunter's syndrome, vertebral artery stump syndrome, cryptogenic stroke, vertebrobasilar insufficiency, rotational vertebral artery compression
