The Evolution of Carotid Surgery

Area of Science:

• Vascular Surgery
• Cerebrovascular Disease
• Medical History

Background:

• The carotid arteries are crucial for cerebral blood supply, and their stenosis is a major cause of ischemic stroke.
• Historical understanding of the carotid arteries' role in stroke evolved significantly from the 17th century onwards.

Purpose of the Study:

• To review the historical evolution of carotid surgery techniques.
• To examine the advancements in treating carotid artery stenosis.
• To discuss the current landscape and future directions in carotid revascularization.

Main Methods:

• Historical literature review tracing the development of carotid surgery.
• Analysis of key surgical innovations and clinical trials.
• Discussion of emerging endovascular and hybrid techniques.

Main Results:

• Early carotid ligation attempts were followed by the development of carotid endarterectomy (CEA) in the mid-20th century.
• Innovations like patch angioplasty and shunting improved CEA outcomes, establishing it as a standard treatment.
• Carotid artery stenting (CAS) emerged as a less invasive alternative, with newer techniques like TCAR gaining traction.

Conclusions:

• Carotid surgery has evolved from basic ligation to sophisticated endovascular and open surgical procedures.
• CEA remains a cornerstone, but CAS and TCAR offer alternative revascularization strategies.
• Personalized treatment for carotid artery stenosis is advancing through research into plaque morphology and diagnostics.
