Temporal arterial ligation in head and neck surgery with absorbable sutures

Area of Science:

• Surgical innovation in head and neck oncology.
• Vascular surgery techniques.
• Biomaterials in medical devices.

Background:

• Temporary arterial ligation is valuable in head and neck surgery for managing hemorrhage and vascular neoplasms.
• The efficacy of absorbable sutures for temporary arterial occlusion requires further investigation.

Purpose of the Study:

• To evaluate the reliability of different absorbable sutures for temporary common carotid artery ligation in a canine model.
• To determine which suture material provides effective transient arterial occlusion for potential surgical applications.

Main Methods:

• Common carotid arteries in dogs were ligated using absorbable sutures: plain gut, chromic gut, and polyglycolic acid.
• Serial selective arteriograms were performed to monitor arterial patency post-ligation.

Main Results:

• Polyglycolic acid sutures demonstrated reliability in achieving transient arterial occlusion.
• Plain gut and chromic gut sutures were found to be unreliable for sustained temporary ligation.

Conclusions:

• Polyglycolic acid sutures are a reliable option for temporary arterial ligation in head and neck surgery.
• This study supports the use of polyglycolic acid for transient vascular control in specific surgical scenarios.
