    Introduction: Stroke in the immediate post operative period following carotid endarterectomy (CEA) is usually due to carotid thrombosis. Many centers have begun incorporating angiography before re-exploration, which has the advantage of confirming carotid occlusion and treating tandem intracranial lesions. The aim of this study is to determine the safety and efficacy of this strategy.

    Methods: A retrospective review was performed of all cases undergoing stenting of the carotid artery following carotid endarterectomy from November 2009 to June 2013 at the Medical University of South Carolina. Charts and angiographic images were reviewed. Four cases of carotid thrombosis within 72 hours of CEA and subsequent stent reconstruction are summarized.

    Results: All patients had greater than 70% carotid stenosis prior to carotid endarterectomy. One patient had intraoperative occlusion and dissection of the ICA which was noted on intraoperative carotid duplex ultrasound. All patients underwent post operative computer tomography (CT) or computer tomography perfusion (CTP) scans with subsequent cerebral angiography and stent reconstruction within 11 hours of symptom onset. One patient had tandem middle cerebral artery M3 branch occlusion which was successfully recannalized. In all four cases, recanalization was successfully completed between 40 to 160 minutes. There were no procedural complications.

    Conclusions: Emergent endovascular evaluation in the setting of acute post CEA thrombosis is a safe and timely treatment option, with the benefit of detecting and treating embolic intracranial lesions. More investigation is necessary to define the role of immediate angiography and intervention in this rare surgical complication.

    Patient Care: By describing a novel therapy for the treatment of acute post CEA stroke

    Learning Objectives: By the conclusion of this session, participants should be able to: 1) Describe the importance of identifying a post CEA occlusion 2) Identify effective treatments for post CEA occlusion
