Summary
This study details a successful surgical approach for a patient with severe carotid artery blockages and coronary artery disease. The technique involved specialized extracorporeal circulation during carotid endarterectomy to maintain brain blood flow.
Area of Science:
- Cardiovascular Surgery
- Neurology
- Vascular Surgery
Background:
- The case involves a patient with critical bilateral internal carotid artery (ICA) stenoses necessitating multivessel coronary revascularization.
- The left ICA diameter significantly exceeded the right, indicating high dependence of cerebral circulation on the left side.
Observation:
- During left ICA endarterectomy, active cerebral perfusion was maintained using extracorporeal circulation.
- Perfusion was administered at 300 mL/min at 23°C directly through the ICA undergoing repair.
Findings:
- The surgical strategy successfully managed simultaneous critical carotid artery stenosis and coronary artery disease.
- Maintaining cerebral perfusion during carotid endarterectomy in a highly dependent left ICA was achieved.
Implications:
- This approach offers a potential solution for complex cases requiring both carotid and coronary interventions.
- The technique highlights the importance of tailored cerebral perfusion strategies in high-risk vascular surgery patients.
