Catastrophic vertebral artery and subclavian artery pseudoaneurysms caused by a fishbone: A case report

Figure 1 Coronal reconstruction of the contrast-enhanced chest CT (A) and digital subtraction angiography of the vertebral artery and endovascular stent implantation (B and C). A: Pseudoaneurysm formation in the initial segment of the left vertebral artery (arrow) and a large amount of effusion in the left thoracic cavity; B: Contrast medium overflow at the start of the left vertebral artery (arrow), suggesting the formation of a pseudoaneurysm; C: The signs of vertebral arterial contrast medium spillage disappeared after stent implantation.

Figure 2 Coronal reconstruction of the contrast-enhanced chest CT (A) and digital subtraction angiography of the left subclavian artery and stent implantation. A: Pseudoaneurysm formation at the start of the left subclavian artery (arrow) and endovascular stent implantation in the left vertebral artery. B: Contrast medium overflow at the start of the left subclavian artery, suggesting the formation of a pseudoaneurysm (arrow); C: After the stent graft was implanted, the contrast medium spillage disappeared.
