# Emergency Carotid Thrombo-Endarterectomy after Failed Endovascular Recanalization for Acute Complete Carotid Occlusion: A Case Report

## TL;DR

A 76-year-old man with a blocked carotid artery underwent emergency surgery after failed endovascular treatment, resulting in a successful recovery.

## Contribution

Demonstrates the safety and feasibility of emergency carotid endarterectomy after failed endovascular recanalization.

## Key findings

- Emergency carotid endarterectomy successfully restored blood flow after failed endovascular attempts.
- The patient recovered well with no new deficits and maintained arterial patency long-term.
- Multidisciplinary collaboration and hybrid operating rooms are crucial for optimal outcomes in such cases.

## Abstract

Rapid identification of the type and origin of a stroke is crucial for prompt and appropriate treatment, which can significantly influences patient outcomes. We report a multidisciplinary management case involving a 76-year-old man who presented with left-sided weakness and mild dysarthria. Imaging revealed a completely occluded right internal carotid artery. Despite multiple endovascular recanalization attempts, adequate flow could not be achieved, leading to the decision to perform an open thrombo-endarterectomy. The patient underwent carotid endarterectomy with microsurgical techniques under general anesthesia. The atheroma plaque and central thrombus were removed, which reestablished flow. Continuous intraoperative neuromonitoring was utilized to ensure patient safety. The patient woke up without new deficits and was discharged for rehabilitation. Follow-up imaging confirmed arterial patency, and the patient eventually made an excellent recovery, including being independent over one and a half years. Emergent recanalization with carotid endarterectomy following a failed endovascular recanalization is both safe and feasible, emphasizing the need for collaboration between different treatment providers to ensure optimal patient outcomes. Our report highlights the importance of a multidisciplinary approach and the advantages of a hybrid operating room in the treatment of acute complete carotid artery occlusion.
