Early Ambulation After Microsurgical Reconstruction of the Lower Extremity

Area of Science:

• Microsurgery
• Plastic Surgery
• Orthopedic Surgery
• Vascular Surgery

Background:

• Timely return to ambulation is crucial for successful lower extremity reconstruction outcomes.
• Current flap monitoring methods have limitations in sensitivity for detecting complications.
• Enhanced postoperative monitoring protocols are needed to improve flap viability and patient recovery.

Purpose of the Study:

• To evaluate the effectiveness of a multimodal monitoring system in enhancing postoperative flap monitoring.
• To assess the impact of this system on initiating earlier patient dependency protocols.
• To improve the sensitivity of detecting poorly performing flaps in lower extremity reconstruction.

Main Methods:

• Prospective analysis of 36 anterolateral thigh free flaps and radial forearm flaps for lower extremity reconstruction.
• Incorporation of a multimodal system including physical examination, ViOptix tissue oxygen saturation monitoring, and implantable venous Doppler into the postoperative monitoring protocol.
• Monitoring for flap viability and progression of patient dependency.

Main Results:

• Twenty-three patients ambulated, and 3 dangled their legs on the first postoperative day.
• One flap exhibited early mottling, which resolved with elevation, and the dependency protocol was initiated on postoperative day 3.
• All flaps achieved successful healing, demonstrating the reliability of the multimodal monitoring system.

Conclusions:

• The combination of physical examination, implantable venous Doppler, and ViOptix significantly increases the sensitivity of flap monitoring.
• This multimodal approach facilitates earlier implementation of dependency protocols and supports successful lower extremity reconstruction.
• The integrated system reliably aids in the early detection of compromised flaps during postoperative recovery.
