Undiagnosed tandem stenosis of the internal carotid artery – A case report

We report a case of a 77-year-old patient with a tandem carotid stenosis diagnosed intra-operatively. Even though standard computed tomography angiography was performed before surgery, second stenosis distal to carotid bifurcation had not been detected. No recommendations or guidelines for managing tandem stenosis are available. It remains an unsolved issue in vascular surgery.
