Simultaneous stenting of the left main coronary stem and internal carotid artery in a hemodynamically unstable...

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Surgery

Background:

• Combined endovascular interventions on carotid and coronary arteries are uncommon.
• Stenting the unprotected coronary left main stem carries significant risk.
• This case addresses a hemodynamically unstable patient requiring combined carotid and left main coronary artery stenting.

Observation:

• A 78-year-old female presented with severe right carotid artery stenosis and left carotid artery occlusion.
• Coronary angiography revealed critical stenosis in the left main coronary artery and occlusions in other major coronary arteries.
• Simultaneous carotid endarterectomy and coronary artery bypass grafting were deemed too high-risk.

Findings:

• The patient underwent successful endovascular stenting of both the carotid and coronary arteries.
• The procedure was completed without complications, leading to hemodynamic stabilization.
• This approach avoided high perioperative risks associated with traditional surgery.

Implications:

• Simultaneous coronary and carotid stenting is a viable and potentially life-saving option for select high-risk patients.
• Endovascular techniques offer an alternative when surgical risks are prohibitive.
• This case highlights the successful application of combined interventions in complex cardiovascular and cerebrovascular disease.
