ICG Fluorescence Imaging to Guide Head and Neck Free Flap Surgery

Official title: Comparing Intraoperative Indocyanine Green Fluorescence Imaging With Standard Clinical Assessment for Flap Perfusion in Head and Neck Reconstruction: A Randomised Controlled Trial (VISION Trial)

Run by Region Skane · NCT07635420 · Data updated 2026-11-12

This trial tests whether using intraoperative indocyanine green (ICG) fluorescence imaging helps surgeons improve flap outcomes compared with standard assessments in adults undergoing head and neck free flap reconstruction.

Is this trial a fit for you?

Likely a good fit

Adults (18 years or older) undergoing microvascular head and neck free flap reconstruction at participating centers who can provide informed consent.

Probably not a fit

Patients with contraindications to indocyanine green or iodine allergy may not benefit from the imaging approach.

What this trial studies

This multicenter, open-label randomized trial compares intraoperative ICG fluorescence angiography plus standard perfusion assessment to standard clinical assessment alone in adult head and neck free flap reconstruction. Primary outcome is partial flap loss requiring intervention within 30 days post-surgery; secondary outcomes include total flap loss, flap-related re-exploration, flap salvage, and postoperative complications. The study aims to determine if real-time ICG visualization can improve perfusion assessment and reduce complications. Eligible participants are adults undergoing microvascular free flap reconstruction for oncologic, trauma, or benign head and neck defects at Swedish centers. The trial plans to enroll 244 participants across sites led by Region Skane, Skåne University Hospital, Malmö.

Why it matters

Potential benefit: If successful, the approach could reduce partial flap loss and related complications, potentially improving reconstructive success and patient recovery.

How similar studies have gone: Previous retrospective studies suggested benefits of ICG angiography for flap perfusion, but high-quality randomized evidence has been limited until now.
