Modified Suturing Techniques in Carotid Endarterectomy for Reducing the Cerebral Ischemic Time

Area of Science:

• Neurosurgery
• Vascular Surgery
• Cerebrovascular Disease

Background:

• Carotid endarterectomy (CEA) is a key procedure for carotid stenosis.
• Shunting during CEA is common but controversial due to potential complications.
• Alternative methods to shunting are sought to improve patient safety.

Purpose of the Study:

• To evaluate two modified arteriotomy suture techniques as alternatives to shunting in CEA.
• To assess the efficacy of these techniques in reducing perioperative ischemic complications.

Main Methods:

• Technique 1: Partial arteriotomy closure with a clamp isolating the middle third, followed by full opening before suture completion.
• Technique 2: Arteriotomy closure at the common carotid artery (CCA), with a clamp isolating the internal carotid artery (ICA) and allowing backflow through the external carotid artery (ECA).

Main Results:

• Both modified techniques successfully reduced cerebral ischemia.
• Technique 1 provided direct reduction, while Technique 2 utilized collateral circulation.
• The methods are simple, safe, and broadly applicable to CEA procedures.

Conclusions:

• Modified arteriotomy suture techniques offer a viable alternative to shunting in CEA.
• These techniques effectively reduce perioperative ischemic complications by minimizing cerebral ischemic time.
