Objective:
Infection after carotid artery stenting (CAS) is rare. We report two dialysis cases of delayed stent infection associated with a carotid dual-layer stent (DLS), which occurred several months after deployment of the stent.
Case Presentations:
Case 1: A 74-year-old man receiving dialysis underwent CAS with DLS. Three months after CAS, the patient developed a high fever, neck pain, and neck swelling. Neck CT and carotid ultrasonography (CUS) indicated an abscess around the inserted DLS. The patient was treated with antibiotic agents and fully recovered. Case 2: A 73-year-old man receiving dialysis underwent CAS with DLS. Two months after CAS, this patient also developed a high fever, neck pain, and neck swelling. Contrast-enhanced neck CT indicated inflammatory effusion with an abscess and a giant infectious pseudoaneurysm. Endovascular stent graft reconstruction was employed urgently under antibiotic therapy to prevent its rupture. However, intracranial hemorrhage occurred postoperatively and left hemiparesis remained.
Conclusion:
Delayed carotid stent infection is a rare but severe complication. The use of a DLS might be avoided during CAS for dialysis cases.
