Early Detection of Vascular Obstruction in Microvascular Flaps using Thermographic Camera

Area of Science:

• Plastic Surgery
• Medical Imaging
• Vascular Surgery

Background:

• Microvascular flaps are crucial in reconstructive surgery.
• Vascular obstruction is a significant complication.
• Early detection of vascular compromise is vital for flap survival.

Purpose of the Study:

• To evaluate the efficacy of a thermographic camera for early detection of vascular obstruction in microvascular flaps.
• To compare thermography with conventional clinical monitoring methods.

Main Methods:

• A cross-sectional study involving 31 patients undergoing microvascular surgery.
• Postoperative monitoring of microvascular flaps using a thermographic camera alongside conventional methods.
• Re-exploration decisions based on conventional methods, with intraoperative confirmation of vascular obstruction.

Main Results:

• Three out of 31 (9.7%) flaps experienced postoperative vascular obstruction.
• Thermographic camera detected complications 2-4 hours earlier than conventional methods.
• The difference in detection time was statistically significant (p >0.109).

Conclusions:

• Thermographic camera is a valuable, non-invasive tool for monitoring microvascular flaps.
• Early complication detection by thermography can potentially change clinical practice.
• This technology enhances the safety and success rates of microvascular reconstructions.
