Dynamic computer tomography determining the patency of buried free flaps

Area of Science:

• Plastic Surgery
• Radiology
• Medical Imaging

Background:

• Monitoring free flap patency is crucial for reconstructive surgery success.
• Existing methods for monitoring cutaneous free flaps are numerous, but options for buried free flaps are limited.
• Rhomberg's disease presents unique challenges for facial contour reconstruction.

Observation:

• A case report details a 39-year-old female with Rhomberg's disease undergoing an abdominus rectus muscle free flap for facial contour correction.
• Dynamic CT scanning was utilized on the sixth postoperative day.
• The study involved comparing density changes in the free flap to adjacent facial muscles.

Findings:

• Dynamic CT scanning provides high-resolution imaging of the entire free flap.
• This technique allows for the assessment of microvascular anastomosis patency in buried free flaps.
• The rate of change in tissue density effectively indicates flap viability.

Implications:

• Dynamic CT scanning offers a valuable, high-resolution method for monitoring buried free flaps.
• This approach can improve early detection of complications, ensuring better patient outcomes.
• The findings suggest a potential new standard for postoperative surveillance in complex free flap reconstructions.
