Vascularized Partial Free Toe Tissue Transfer Under Local Anesthesia

초록

Background This study was designed to introduce free toe soft tissue transfer using local infiltration anesthesia in patients not suitable for general anesthesia and local tissue coverage. Methods From January 2006 to August 2012, a total of 11 traumatic fingertip defects were reconstructed by toe soft tissue transfer. All procedures except 1 were done as primary reconstructions, with either the lateral side of the great toe (5 cases) or the medial side of the second toe (6 cases) used as a donor. Postoperative follow-up periods were between 8 months to 2 years and 6 months. Results Flap sizes varied from 1.0 x 2.0 to 2.0 x 3.5 cm. The mean operative times were 4 hours 29 minutes for cases done by a single team and 3 hours 21 minutes for cases done by a 2-team approach. Approximately 5.8 mL of local anesthetic agent was used in each finger and 5.9 mL was used in the toes for a total of 11.7 mL. All flaps survived and were fully taken without complications, except 1 case that presented partial necrosis. Conclusions Fingertip soft tissue reconstruction by free toe tissue transfer under local anesthesia uses a more limited operative field, with a shorter operative time, enabling reconstruction in patients not suitable for general anesthesia. This is even more so with a microsurgical 2-team approach, which reduces the volume of anesthetic agent needed, making this method a sufficiently realistic option for fingertip soft tissue reconstruction.
