Internal jugular vein patency following carotid endarterectomy

Area of Science:

• Vascular Surgery
• Medical Imaging
• Anatomy

Background:

• Carotid endarterectomy is a common surgical procedure.
• Internal jugular vein (IJV) cannulation is frequently used for central venous access.
• Concerns exist regarding IJV patency and position after ipsilateral carotid endarterectomy.

Purpose of the Study:

• To evaluate the patency and anatomical position of the internal jugular vein on the side of previous carotid endarterectomy.
• To determine if prior carotid surgery impacts the suitability of the IJV for cannulation.

Main Methods:

• Ultrasound examinations were performed on 45 patients with a history of carotid endarterectomy.
• Fifty-five internal jugular veins were assessed (including 10 bilateral procedures).
• Assessment focused on the patency and relationship of the IJV to the carotid artery.

Main Results:

• All examined internal jugular veins were found to be patent.
• The internal jugular veins were consistently in a normal anatomical relationship to the carotid artery.
• No adverse findings were noted in relation to prior carotid surgery.

Conclusions:

• Previous carotid endarterectomy does not compromise the patency or normal positioning of the ipsilateral internal jugular vein.
• Internal jugular vein cannulation can be safely considered in patients with a history of carotid surgery.
• The findings support the use of IJV for central access in this patient population.
