Stent infections are exceedingly unlikely, particularly in the internal carotid artery (ICA).The treatment for these patients is still under debate, with a high mortality rate.In this article, we report a 47-year-old male patient who underwent stent implantation in the right ICA and presented with infection and pseudoaneurysm at the stent site 15 days later.The patient was managed with antibiotics and dual antiplatelet therapy. In cases where the pseudoaneurysm does not continue to grow, early antibiotic treatment can keep the stent infection under control.
