Case Report: Redo carotid endarterectomy with patch angioplasty for treatment of restenosis caused by excessive intimal hyperplasia following endarterectomy: illustrative case

Symptomatic restenosis caused by simple intimal hyperplasia shortly following CEA is relatively uncommon. In contrast to atherosclerotic plaques, this dense and fibrous tissue is more resistant to dissection and may lead to a reduction in vessel diameter. Neither standard CEA nor CAS alone can adequately prevent long-term restenosis. However, CEA combined with patch angioplasty has been shown to be an effective therapeutic option for this specific type of stenosis.
