OBJECTIVE AND IMPORTANCE: Bow hunter's @entity64 is a symptomatic @entity9085 caused by @entity850 or occlusion of the vertebral artery at the C1C2 level with @entity717 . No case of anterior decompression of the vertebral artery for surgical treatment of bow hunter's @entity64 has been reported. CLINICAL PRESENTATION: A 47-year-old male @entity1 presented with repeated episodes of @entity909 caused by turning his head approximately 40 degrees to the right; he recovered consciousness within approximately 10 seconds after his head was returned to the neutral position. Angiography revealed an occluded right vertebral artery and temporary occlusion of the left vertebral artery, at the level of the C2 transverse foramen, when the @entity1 's head was turned approximately 40 degrees to the right. INTERVENTION: Anterior decompression of the left vertebral artery at the transverse foramen of the axis was performed. Postoperative angiography demonstrated sufficient flow in the left vertebral artery even when the neck was rotated. CONCLUSION: The @entity1 was discharged without @entity51 . We demonstrate that simple surgical untethering of the vertebral artery at the transverse foramen of the axis is an effective method of treatment that avoids the limitation of @entity717 . The advantage of this procedure is that it does not result in postoperative restriction of the @entity1 's neck movements. The anterior approach, with decompression of the transverse foramen of the axis, in the present case provided adequate exposure of the vertebral artery and resulted in a satisfactory outcome.
