A case study of the disconnected dual taper tip of the Wingspan stent during percutaneous transluminal angioplasty and stenting of the vertebral artery

•The dual taper tip of a Wingspan stent was entrapped in the stent after deployment.•The inner body of Wingspan stent was disconnected and the stent was occluded.•Insufficient dilation of the stenotic lesion may lead the dual taper tip entrapment.•Angioplasty for the CTO of the contralateral VA prev...

Description
Summary:•The dual taper tip of a Wingspan stent was entrapped in the stent after deployment.•The inner body of Wingspan stent was disconnected and the stent was occluded.•Insufficient dilation of the stenotic lesion may lead the dual taper tip entrapment.•Angioplasty for the CTO of the contralateral VA prevented functional BA occlusion.
