Controlled hypothermia in carotid endarterectomy

Area of Science:

• Cardiovascular Surgery
• Neurology
• Vascular Medicine

Background:

• Recurrent transient ischemic attacks (TIAs) and amaurosis fugax indicate significant cerebrovascular disease.
• Complex carotid artery disease poses surgical challenges.
• Controlled hypothermia is a potential adjunct for neuroprotection during carotid endarterectomy.

Observation:

• The patient presented with ipsilateral vertebral artery obstruction, contralateral internal carotid artery obstruction, and contralateral external carotid artery stenosis.
• Shell cooling was employed to induce controlled hypothermia.
• Carotid endarterectomy was performed successfully under these conditions.

Findings:

• Controlled hypothermia via shell cooling facilitated a successful carotid endarterectomy.
• The surgical intervention addressed the patient's complex arterial anatomy and symptoms.
• The case highlights the feasibility of hypothermia in challenging carotid endarterectomy scenarios.

Implications:

• This case demonstrates the utility of hypothermia in managing complex carotid artery disease.
• The findings suggest hypothermia may be a valuable technique for neuroprotection in select carotid endarterectomy patients.
• Further research into the indications and techniques for hypothermia in vascular surgery is warranted.
