Transient single-digit ectopic implantation.

Abstract

Although immediate replantation of an amputated digit is always preferable, mitigating circumstances (such as a severe concomitant injury involving the appropriate recipient neurovascular structures) might preclude such an attempt altogether. However, if these local structures have the potential, following adequate debridement and/or other tissue transfer, to accept this digit later, than an alternative for transient storage for delayed replantation should be considered. The deep inferior epigastric vessels are a recognized convenient site that could provide temporary ectopic revascularization of such a solitary finger. An example of this approach for thumb preservation is presented, although amputation of the hand before performing the secondary transfer unfortunately proved prudent.
