Hunter’s bow syndrome is characterized ultrasonographically by narrowing of blood vessels during head rotation, decreased blood flow, and slower blood flow than on one side of the head. Hunter’s bow syndrome, also known as rotational vertebral artery occlusion syndrome (RVOS), or archer’s stroke as it was discovered by a hunter who was practicing archery, is characterized by unilateral occlusion of the vertebral arteries, resulting in vertigo, miosis, nystagmus, abnormal sensation of the face on one side, or weakness in the upper and lower extremities. The manifestations mostly resolve when the head is returned to a neutral position. Hunter’s bow syndrome may be caused by abnormal bony or soft structures that cause dynamic narrowing of the vertebral arteries and hemodynamic abnormalities when the head and neck are rotated or hyperextended, thus causing posterior cerebral circulation dysfunction. It is recommended that patients with symptoms such as vertigo, tinnitus, and blurred vision when their head is rotated should seek timely hospital consultation and examination, and targeted treatment should be given after a clear diagnosis is made.
